In Lifegazer’s thread on relativity, he raised the issue of the experience of relativity, then Fliption gave what I thought was a solid interpretation of that idea, and I raised the matter again in my thread on potential. So far no one has offered any suggestions on what to expect and so I remain very curious to hear opinions on this. I’ve framed the question in GR’s twins paradox.

The question is, would each twin's experience of time be the same? Say the traveling twin were gone five years according to shipboard clocks, and when he came back to Earth saw that 40 years had passed according to Earth clocks.

Although only five years had passed would the traveling twin feel like it had been the longest five years he'd ever experienced? That is, though his physical situation had been subject to time constriction, did it also make his consciousness fully relative to the physical circumstances?

You try spending five years cooped up on a rocketship and tell me it isn't the longest five years of your life. (sorry, just had to get that in.)

That's funny Wuli, but not a bad point either. For the sake of proper control in this experiement, I suppose we'd have to make the spaceship a Galactica-type, so it was big enough to keep someone from going nuts.

You just answered your question, if in fact your'e allowed to provide for everyone's comfort and "well being."

Not really. The idea is simply to not have excessive discomfort be the cause of judging "time" as longer than usual.

What we are after is if all other factors are constant, will the experiences of those in significantly different frames of GR reference be noticable?

If I feel comfortable and I feel fine, then I doubt if I'm going experience anything other than "what's normal." Including time.

Otherwise we'll need to address those "ill-effects," lest we get sick and die.

Not at all. They would experience time in exactly the same way.

Think of it this way: up to the moment one of them turns around (breaking the symmetry of the system), there is no way of telling who will be the youngest brother when they get back together.

Another way of undestanding it is this: relativistic time dilation affects all processes that you can use as measures of time. This not only includes quartz chrystals and radioactive decays, but also all those electrochemical processes that happen while you experience what you call "thinking".

The heart of the issue is that you cannot say that one twin has the "real" time, while the other is "delayed". This would be the same as assuming the existence of a preferred frame (plus the indefensible assumption that one of the twins is at, or closer to, the "right" time).

I probalby should have made it more clear that I've assumed the twins grew up together, and so when the space trip happens, the traveling twin will have an experience of time that is different from that in which he grew up. I do NOT mean one frame of reference is preferred; I mean one frame of reference conditions the traveling twin to expect a certain pace of time.

True for purely material processes, which it seems you are assuming that consciousness is fully a product of. But even "thinking," on this issue at least, is preceded by the traveling twin's experience. I am asking if the traveling twin's consciousness will notice the difference in the rate of time.

There is no "difference in time rate" to notice (at least not in the way you are thinking of it). Instead, for the "traveling twin", the distance "traveled" is shorter than that measured by the "stay at home" twin, and thus takes less time to traverse.

I am going to question you further, not because I necessarily disagree, but because I do not yet believe what I am asking you answered.

First, let me be certain I understand your interpretation. When you say there is no difference in time rate to notice, are you saying that time has not been constricted for the traveling twin during the journey? It is "space-time" is it not that has been altered?

If time is not an issue, then how can it be the traveling twin finds his brother 35 years more aged than himself?

Spacetime isn't truly "altered" at all, it is just perceived in different ways. In any case, both twins' clocks, brains, rulers, bodily functions, lightbulbs, control pannels, anything, seem completely normal. The twin who comes home to find himself younger than everybody else will be very surprised, because his clock said it only took a little while, at no time did he feel as though time was being slowed down, at no time did anything seem unusual, unless he had decided to take a look at his surroundings closely.

And, as archaron has said, it's not as though the twin on the rocket is in motion and the other is at rest. Halfway through the whole cherade, while the rocket twin is still on his way off, niether twin can be said to be older. From the perspective of the earth-twin, the rocket twin should be younger. From the perspective of the rocket twin, the earth-twin should be younger. It is when the rocket-twin turns his ship around and starts heading back that he has altered things to the point that he, is for sure, the one that will have aged less. He passed through 2 different realms of time (with respect to the earth-twin.)

This statement is so full of inconsistencies. The major one being between your first sentence, and your final sentence.

LWS... What you should realize about Relativity, is that it states all observers experience a different/unique universe. They literally experience a different universe. In the case of the twins, one might see his whole universe age 5 years, and the other twin 40 years.
Let's imagine if we sent 2 brothers to watch a game of football from different positions in the stand (this analogy loosely mirrors the spacetwin scenario, whereby the universe can be equated to ~the game~). If we sit next to the person who experiences the whole game (representing the earth-twin), we can know via the Lorentz-transformation, that the other observer (the spacetwin) has yet to see the second-quarter start.
Paradoxically; what would now happen if the guy who had already seen the game was now to go and 'sit with the observer' (have motion and position like the spacetwin) who has not yet seen the whole game? [Let's imagine that this observer (earthtwin) has the capacity to catch-up with the other observer in a matter of seconds - which wouldn't be difficult if they shared the same radial-of-orbit, as in my thread's example.]. Would he see the second-quarter (or catch the end of the game) again as he met up with his brother? Of course not. This would require time to actually reverse.

I can almost agree that "both twins' clocks, brains, rulers, bodily functions, lightbulbs, control pannels, anything, seem completely normal." What you assume is that every element of a human being will be subjected to relativity; I am wondering if experientially he will be made to fully accommodate relativity.

Because relativity is only a physical principle, the question becomes one of the nature of consciousness. If it is purely mechanistic and purely matter generated, then we'd expect consciousness to be fully subject to relativity. But if there is an immaterial aspect to consciousness (and I don't necessarily mean "divine," just "non-material"), then we might expect it to notice that its physical environment is aging slower than it had gotten used to on Earth despite the fact that clocks, rulers, and all other measuring devices registered "normally."

Yes, but isn't it that the traveling twin's one year equals the Earth twin's eight years? Isn't it that the universe itself ages at a rate independent of the observers, and that it is measurement that is affected?

I freely admit that relativity paradoxes can make my brain ache, and I am open to learning all I can from anyone who understands relativity better than I. Yet in this thread at least I am not so interested in the details of relativity as I am in understanding how consciousness would be affected. In my example the traveling twin was already used to Earth's rate of time. Since relativity is a physical effect, and I don't believe consciousness is 100% physical, then it seems to me that the traveling twin will have some sense that his shipboard five years was the longest five years he'd ever experienced.

If time is not an issue, then how can it be the traveling twin finds his brother 35 years more aged than himself?

Let's break it down into what is measured from each frame.

Earth twin:

He sees his brother accelerate up to some large fraction of c Relative to himself and then coast. As a result, he sees his brother's time rate as running slower than his own. After coasting for some distance(Let's say to Alpha Centauri), his brother decelerates, and comes to a stop relative to him (the Earth twin). The space twin then accelerates back towards Earth, Coasts again, and then decelerates to a stop again next to him again.

According to the Earth twin, his brother's clock should show less elapsed time and his brother should have aged less than him, because of the large relative velocity difference between them during the majority of the trip.

Space twin:

His sees the Earth accelerate away from himself, while Alpha Centauri accelerates towards him. He also notes that there is a g-force acting on everything in the ship, acting in the same direction as the Earth and Alpha Centauri are Accelerating, and with a force that equals the rate of that acceleration.

This can be explain in two ways, that he is accelerating towards Alpha C, Or, He is standing still in a uniform Gravitational Field, and Earth and Alpha C are falling in it. Either assumption will give the same result because of the Equivalence Principle (equating Accleration and Gravitation), So we will use the second interpretation, as it allows us to treat the space twin as "fixed" frame of reference".

Therfore the Space twin sees the Earth fall away from him and Alpha Centauri fall towards him. As a result, he wil see the combination of two effects on his brother's time rate; one due to the Earth's increasing relative velocity, and one due to the Earth's position in the gravity field. Since Clocks lower in a gravity field will appear to run slower as measured form a frame higher in that field, he will see his Earth twin's brother's time rate as running slower. This is compounded by the fact that the Earth has an increasing Relative velocity, which will also decrease its time rate.

The g field leaves ( This corresponds with what the Earth twin sees as the "coasting" period.) Earth and Alpha C. now maintain a constant relative velocity with respect to him. He will see the time rate on Earth as running slower than his. He also will see length contraction in both the Earth, Alpha C and the distance between them (Earth and Alpha C are just two points in the same frame that is moving relative to him.) It will take some time (t) for this frame to go from The Earth being near to Alpha C being Near. This time will be shorter than that measured by his Earth Brother during this same period. (His Earth brother see him (travel 4.3 ly at a given speed taking a certain time. He sees Earth and Alpha C Fly by him at the Same speed, measures the Distance between them as less than 4.3 ly, thus the transit takes less time.

The g field returns, but this time it points the other direction. (Earth is now Higher in the Field.) But not only is Earth now higher in the Field, it is much higher than it was lower earlier.(He is close to Alpha C and Far from Earth) The Earth's time rate will now be measured as running faster than his own (much faster than it was running slower before.) Fast enough, that by the time the g field leaves again and the Earth and Alpha C are once again at rest relative to him, all the time he saw it losing during the other periods are made up, plus some. This "plus some" will be exactly the amount that the Earth twin will have seen as due to the Space twin's time rate moving slower.

The second half (That where the Earth returns to being next to him) will be just a mirror image of the first.

Meaning that when the twins are re-united they agree as to which twin has aged the least(or most) and by how much, but not as to why. By each twin's frame the time difference is due to the combinations of length contractions and time dilations his brother went through.

Thank you Janus for such a thorough explanation; it was one of the best I've seen here and cleared up a couple of points for me about the physical side of relativity.

I am not sure you understand where I am coming from. That the details are crucial for sound understanding of relativity I do not doubt. But it seems you automatically assume a consciousness raised in Earth's frame of reference will "follow" physical relativity on the spaceship journey because, I suspect, you see no difference between the consciousness and physical reality.

That really is what my point addresses. Since consciousness and brain are equated, I think the materialist position will be that the traveling twin will not notice any difference (even though he grew up on Earth) because his entire frame of reference, including his brain, adjusted to the rates of change during his journey. As for me, I am not convinced I wouldn't notice that my rate of change had slowed (relative to my prior experience on Earth) because I don't think consciousness is 100% determined by physical factors.

Here you go again, spouting off about Relativity, when you don't know what you're talking about.

Both twins would see the exact same proportion of the "game" played. One will just say that it took longer to play out. While One twin will say the first half took 1 1/2 hrs, the other will say it took 3. If the twins compared notes at any point of the "game" they would agree exactly as to which play just transpired, But wouldn't agree to how much time has expired(By their clock) since the Game started. Either one Twin will see the game progress in slow-motion or the other will see it progress in fast motion. (Or one will see it in fast motion while the other sees it in slow motion.) Also, if either twin took his field glasses of the field to scan the stands to find his brother, he will see him (and those sitting around him), as either moving in fast or slow motion.

Who sees what depends on each twin's "position" (relative velocity and Gravitational potential) Relative to the the "field" and each other.

I think you missed the point of this statement:

By each twin's frame the time difference is due to the combinations of length contractions and time dilations his brother went through.

Put simply: "Relativistic effects always happen to the other frame.

You never have to worry about how your "consciousness" reacts to Relativistic effects, because you or nothing else in your frame experiences them. It is always the other frame in which the effects are measured (by you or anything in your frame).

This is what "no preferred frame of reference means".

Good point, and it mirrors how we all live even in the same frame of reference.

However, I am not talking about comparing myself to my twin when I get back, but rather, comparing my experience of 5 years on Earth to my experience of five years while traveling.

LOL, thanks LG, that's what happens when you write late at night. You don't explain things thoroughly enought.

Yes, the first sentence does seem to contradict the final sentence. However, notice that I said "with respect to the earth-twin." That doesn't completely clear things up, but it does a little bit to alleviate that. Anyway, I was digging myself into a hole saying that "Spacetime isn't truly 'altered' at all." That's confusing. I was just trying to get across the point that a meter is still a meter, no matter what reference frame you use.

The rest of the post, however, is correct. There aren't any other inconsistencies, unless you can point one out to me. It is true that the twin who turns himself around is the one that ends up with the slower clock, due to the explanation Janus just gave. The entire post is worded horribly though, I'll definitely give you that much.

Take care. --Carter

LW Sleeth, it doesn't come down to whether the mind is material or not. It comes down to the basic premises of relativity. The idea of relativity is that no reference frame can be said to be better than another, and that all things within that reference frame are entirely consistent. If they weren't, everything would break down. The point is, the observer is always at rest in his reference frame. He therefore shouldn't be able to feel anything as being different, no matter what kind of mind it is he is using to feel it.

You see that's just it, for those five years, you aren't travelling, it's always the other twin that is doing the travelling, because your frame of reference is always said to be at rest.

Hmmmmmm . . . let me see if I can explain the exception I see to this. And please, I hope you, or Janus, or anyone else wanting to make sure relativity is properly explained and understood do not think I have any interest in challenging relativity. Consciousness, however, I see as not necessarily physical (or only physical), and because of that I cannot yet accept an assumption you are making about it in relativity.

Let's contrast two types of awareness.

Say a computer is able to generate awareness intelligent as humans are right now. The computer lives in an entirely electronic world where every device it interacts with is powered by the same source; the computer shares the same power source too. On hot days when air conditioners around the county are straining generators, the power level of computer's shared power supply drops. Now it and everything connected to the power supply slows proportionately; plus, the computer's awarenes slows too, and so notices absolutely nothing is different.

A neighbor intelligently-aware computer also lives entirely in an electronic world with lots of other electronic devices. All the devices share a common power source. However, this computer runs on its own generator, and so when air conditioners around the county slow down all the appliances around it, it notices the difference.

Similarly, if consciousness is purely a product of materiality, then when all materials slow or speed up, it should "follow" that and not notice any difference. But if some aspect of consciousness remains constant despite physical rates of change, then we might expect one to notice.

Does that make sense?

True. But I am really talking about noticing a difference in the rate of change in my frame of reference compared to the rate of change in my prior frame of reference.

I'm aware of the part in red. The point I was making is that when the twins suddenly meet-up, there is a distinct time-difference apparent in their appearances, too. One looks older than the other. For in what sense can we say that the twins have had a different experience of time, if their bodies are not different? Indeed, if the spacetwin returned after sufficient time, his brother would have aged into dust (being so old himself, he's dead). The Lorentz-transformations aren't just clever-math. They point to real experiences for each observer.
Therefore, we must assume that if the twins meet 'in the stadium', that they will have had real experiences in-line with the Lorentz-transformation (the math of relativity).
Therefore, we must assume that one twin has actually seen less of the same 'game' that his brother has been observing. Correct?

You can't have it both ways. You cannot say that the Lorentz-transformations point to each observer experiencing different times for the same event, unless you acknowledge that this is actually the reality of the situation, and that the spacetwin has actually experienced less of that 'game' than his brother.
And in that sense, you are wrong to state that the brothers can have different experiences of time, when if when they meet-up, they've both seen that game in its entirety.
A game lasts 80 minutes (or is it 40?). That's not important. What is important, is that 2 observers cannot watch the same game and say that they've both watched the same number of 'quarters'. For if this is the case, then in what sense can we say that they've had different experiences of the same game, concerning time?

But you don't change frames of reference. In the Twin paradox for instance, for the space twin, it is the Earth that changes frames. There is no "prior" frame of reference to compare your rate to.

No, not correct. The "game" is just another frame of reference, which each twin is observing from his own frame of reference. They just see the time in this frame and each other's as progressing at different rates.

Since each frame will have its own time rate (as measured form any other frame), How long the game lasts depends upon which frame you measure it from. It could last 80 min from the frame of the field itself, 160 mins for one twin, and 40 mins for the other. At the end of the game bring both twins onto the field (Within the same frame) both twins will agree that they saw the whole game from their seats, and the officials on the field will say the game is over. But if they compare clocks.(sychronized before the start of the game. they will show different times, and twins and officials will each have aged the amount as shown on their respective clocks.

This is what Relativity and the Lorentz contractions say. Not what you are trying to pass off as what they say.

Yes, it does make sense, but again, it comes from a misunderstanding of relativity. I can't blame you for that, it is indeed pretty counterintuitive. It comes from this idea you have in your head that it has to do with all the materials in that frame of reference slowing down or speeding up. There aren't any "physical rates of change" caused by relativity. What you have to understand is that in a particular reference frame, nothing is running slow etc. It's not that everything in there is slowed down proportionally to everything else so it seems normal. It's that everything is normal.

Think of it like this. Right now, we are moving away from some parts of the universe at almost the speed of light. But we consider ourselves to be at rest. There is no way to decide who is at rest. There is no absolute frame of reference that decides whether you are moving or not. It therefore makes no sense to think that time should feel different for any particular mind based on its "motion." The only way that could happen is if all our minds somehow communicate with each other and decide who is at rest, which is ridiculous.

Therefore, we must assume that one twin has actually seen less of the same 'game' that his brother has been observing. Correct?
This seems to be your fundamental misunderstanding of SR, lifegazer. He will have seen the entire game (if he's watching it), it will just have taken a different amount of time to finish. The players will appear to be moving faster, or slower, the clock on the scoreboard will be moving at a different rate in comparison to each observer's clock.

True, one is always in his own frame of reference. I said something I didn't mean. I will explain what I meant in my next post to CJames.

Thank you CJames for bearing with me (thanks to Janus too). I will tell you why I believe some part of your explanation isn't just counterintuitive to me, but it appears to contradict physical facts.

You say that "nothing is running slow etc. It's not that everything in there is slowed down proportionally to everything else so it seems normal. It's that everything is normal."

Let's compare the circumstances of the twins paradox at a couple of stages. While traveling, that twin sees all measurements of time as normal, as does the Earthbound twin.

When the traveling twin returns home however, 35 more years have passed there than on his ship. I am not saying that either frame of reference is the "true" one, but something different has occurred in each situation because the traveling twin and his spaceship have aged at 1/8th the rate that Earth and its inhabitants have. I mean, each twin is going to notice that!

If it weren't for that difference in aging, then I would agree with you. But that aging is a physical fact, and it is a fact of change. What is the nature of aging-type change? Overall it is entropic, and so it appears that the rate of entropy was affected by acceleration. If time is the rate of entropy, the accelerating spaceship slowed "time" by increasing its mass/gravity during acceleration, which we might expect would alter the rate of entropy.

Before getting back to "experience" of relativity, let's see if you agree that actual, physical differences result between someone accelerating and someone zooming along at a (relatively) constant rate.

This is just totally wrong. Your (and Janus') position, is that both observers see an 80 minute game at the same rate (literally). One brother flies-off into space, then experiences time to slow-down (relatively) to his brother on Earth. So; would you please explain how this spacetwin has had this tangible-experience of time-distortion if he has seen as much of 'the game' as his brother, when they meet-up?
I promise you that your argument will not stand-up to logic. If the spacetwin has experienced a 'normal 8o minutes' of the game at the same rate as his brother, then it is impossible for them to have experienced time & space differently. I promise you. If you argue against this fact, then you are exhibiting a total ineptitude to logic.

No, not correct. The "game" is just another frame of reference
It's an identical game of reference, as observed by both twins. It is 'absolute', in this sense. What the game might observe of itself is irrelevant. If the quarterback scores in the first quarter, then he scores in the first quarter for both twins. Fact. What the game might observe of itself is irrelevant. The same game is observed by all.
The question here, is whether the spacetwin has seen less 'quarters' than his brother on Earth. If you read my last post, to CJames, then you'll see that I say that he does - and he must - for the lorentz-transformations to have any tangible meaning. If they don't have tangible/experienced meaning, then what do the Lorentz transformations mean to each observer? Nothing.
which each twin is observing from his own frame of reference. They just see the time in this frame and each other's as progressing at different rates.
And yet, when they meet-up (as I did stipulate), you are advocating that both twins shall have seen as much of 'the game'. What happens if we bring-them together at the final-whistle? - Both twins have just had a supposedly-normal experience of an 80-minute game, at the same rate (according to you). So where does the experience of a time-distortion come into it?
Since each frame will have its own time rate (as measured form any other frame), How long the game lasts depends upon which frame you measure it from. It could last 80 min from the frame of the field itself, 160 mins for one twin, and 40 mins for the other.
That's what the math tell us. That's what I'm working on (though I argue that 'the field' does not have its own given frame-of-reference. Its frame-of-reference is the observer who sees that field like it is). It just-so happens that all observers shall see the 'same game', eventually.
All observers will see 'a field'. Some will say that the field is longer or shorter than what you think it is. Similarly, some observers will tell you that less events (of experienced time) have happened upon that field. That is exactly what space-time distortion of 'the field' does. It changes your experience of time & space.
Hence, you must acknowledge that the spacetwin will not only measure a different length of the field (assuming he had the technology to do so, from his position); he will also experience less events happening upon that field. This is the only way to make the Lorentz-transformations become 'real' (as experienced) for each observer.
At the end of the game bring both twins onto the field
Better-still; imagine we can bring the spacetwin back to the earth-twin's extra-wide seat at the almost-exact moment of the final-whistle. Now let's scrutinise what you say next...
(Within the same frame) both twins will agree that they saw the whole game from their seats, and the officials on the field will say the game is over.
As confirmed earlier, you are advocating that the 2 twins can see the same 'game' at the same rate. And next, you say this...
But if they compare clocks.(sychronized before the start of the game. they will show different times, and twins and officials will each have aged the amount as shown on their respective clocks.
This is literally nonsensical. Sincerely. How can their clocks move differently if the players on the pitch have not? Can the spacetwin see a 'normal' game in 13 experienced-minutes, for example? How? How can the spacetwin have a 'normal experience' of 13 minutes, and see a full game of football?
Let's face it, if this was the case, then the spacetwin's experience of time is far from 'normal'.
This is what Relativity and the Lorentz contractions say. Not what you are trying to pass off as what they say.
With all due respect, I don't think logic/reason supports your imagined reality of Einstein's work. There is no logical-way that your explanation mirrors any sense of the Lorentz-transformation.
I apologise for being direct. But this is important. Please address it.

At the same rate? Where did this come from. Let's try this again. The game is one frame of reference. One observer is in motion with respect to that reference frame. Within the observer's reference frame, time is running normal. Outside his/her reference frame time is wacked. From the perspective of the observer, the game is running faster/slower than he/she would expect it to be. But the observer does not miss any part of the game. It simply seems to take place in less/more time. The watches of the players are moving faster/slower than his/hers. His/her time feels entirely normal, but the games seems to be wrong. Does it make sense yet?

How's it going LW?

Yes, there are actual, physical differences. Ultimately, when the twins meet again, one of them will have aged more, and one will have aged less.

When the traveling twin returns home however, 35 more years have passed there than on his ship. I am not saying that either frame of reference is the "true" one, but something different has occurred in each situation because the traveling twin and his spaceship have aged at 1/8th the rate that Earth and its inhabitants have. I mean, each twin is going to notice that!
I like how you worded that, because it fits quite perfectly. Yes, something is different. The thing is, that "something" is different depending on which reference frame you use! Crazy isn't it? True though. I'm not sure you understand this yet, but there is more to SR than time dilation. There is also length contraction, which plays a big part. Both reference frames will agree on the final results, they disagree on the means. The rocket-twin will notice that the surrounding universe, traveling at near lightspeed compared to the rocket's reference frame, is contracted in length. He therefore doesn't believe he traveled as far as the other twin believes he did.

Each twin will disagree. One twin finds that the other's measurements say something traveled half as far, with clocks running twice as slow. The other will say something traveled twice as far, with clocks running half the speed of the other. But they agree on the result.

Yes, it can be mindboggling, but I do understand this. Neither twin is "right' in his interpretation of events because all events are perfectly consistent within each twin's frame of reference.

I understand this too, and actually it supports my notion that acceleration is constricting the traveling twin's entire frame of reference relative to the Earth twin.

So, now that we agree that the actual physical rate of change differs in each frame of reference, let's return to the theme of this post.

Will the twin raised at Earth's rate of change notice it when his rate of change is altered by acceleration? I refer you back to my "computer awareness" analogy as the basis of my query.

You still haven't gotten the concepts of Relativity correct, Neither twin experiences time or space dilation, he measures it as happening to the other twin.

Your post contains so many intertwined misconceptions, It would take much more time that I have to correct them all. Add to this that you show no inclination towards wanting to unlearn your misconceptions, and its more work than it worth.

So Instead, let's simpilfy things by dealing with one aspect of Relativity at a time. And if you can come to grips with it, then maybe we can proceed further.

Instead of a twin traveling at high relative velocity, let's just put them in different gravity potentials. ( One in a valley and one on a mountain top) This way we only have to deal one Relativistic effect rather than many. And don't have to deal with the complication of changing distances btween the twins.

According to Relativity, the time rate at the top of the mountain runs faster than at the bottom of the valley.

The mountain twin's time runs faster, (His clock runs faster, he breathes faster, his heart pumps faster and his thought processes run faster.) Since everything on the mountain top shares the same time rate, as he looks around him everything looks normal.

But this only applys to those things within his frame, (Sharing the same or nearly the same Gravity potential as himself) not to things outside of this frame!

If he looks at something at Sea level (or at anything else at a different gravity potential wrt to himself) , he will not see the clocks run or events take place at a rate that matches his own.

If he watches a game taking place at Sea level the game will take a longer amount of time to play out for him than it does for someone on the field. For him events on the field will take place at a slower rate because it time runs slower at lower gravity potentials than his own.
But since anyone in the stadium is in the same frame as the game, they will share the same time rate as the game. (If the game take 80 min to play on the field, These spectators will see it take 80 min also , Even though the mountain twin sees it as taking a longer time. (Actually, From the Mountain Twin's frame, it isn't that his time rate is altered by his high altitude, but that the stadiums time rate is altered by its lower alitude)

From the valley twin's frame, the game will appear to run faster. (The stadium is at a higher altitude than the valley twin's frame. ) Again, the Valley twin looking around at things sharing his same altitude will see them behaving at a normal time rate.

If the mountain twin looks at the valley twin he will see the valley twin's time as moving even slower that the stadium's. And if the valley twin looks at the mountain twin he will see the mountain twin's time rate as running even faster than the stadium.

How fast the game "really" played out depends on from which frame it was measured.

The same goes for another time period, that between sunrises. If over any given period you were to ask the Mountain twin, the Valley twin and someone in the stadium how many sunsets they've seen, they would all agree, even though they would'n't agree to how much time has passed over the period. Each would just measure the time between sunsets as taking different amounts of time.

I promise you that your argument will not stand-up to logic. If the spacetwin has experienced a 'normal 8o minutes' of the game at the same rate as his brother, then it is impossible for them to have experienced time & space differently. I promise you. If you argue against this fact, then you are exhibiting a total ineptitude to logic. [/B]

The only thing this exhibits is your ineptitude at understanding the concepts of Relativity, even after they have been explained to you many times, and in many ways.

But then it is not to your advantage to understand Relativity, you then might discover that you've built a 'house of cards'

The game only takes '80 mins' when measured from the same frame as the game. As measured from other frames it will take different times to play out. We've already said that the game will take different times to play out as measured from different frames. That same 80 mins as measured from within the frame of the game, might be measured as 160 min from a different frame.

What is so hard about all this that you can't see it?

What a crock. He 'measures' nothing about the time of the other twin. He only experiences the differences when we get them 'on the same seat'.
That's a fact. Don't lie to this forum (and since you're in a position of respected-authority, you should be doing your utmost to be 'responsible' here). The spacetwin experiences his reality. He does not experience/measure the reality of other observers. At least; not until he experiences the different experiences of those observers (when he sits on the same seat as those observers). The spacetwin doesn't measure the experiences of other observers - he measures his own experiences. That is a fact upon which Relativity hinges.

You won't budge; will you? I can just 'sense' it. You just utterly refuse to contemplate my ideas as being sensical - despite Ahrkron & Tom both admiting that my ideas are compatible with Einstein's work. I somehow sense that you are the biggest materialist in the whole 'plot'. You have certainly given me no indication that you have ever taken me seriously. No matter what I say.
If it is your intention that I shall become bored of this pursuit, then you are probably correct. However, for the time-being, I will challenge established-philosophies until you kick me out of these forums and thereby admit that you are defending a materialistic-bias. You certainly are not defending science here. You are defending your own philosophy: ~Materialism~.
You have no moral right to kick me out of a philosophy-forum for attacking a specific philosophy. Please contemplate that before you kick me out. Therefore; please don't kick me out (as I love posting here). But I won't change my philosophy. Not unless you can prove its unreasonable. To-date, you have not.
I don't just challenge you with a philosophical-dilemma here. I challenge you with a moral dilemma. Is materialism big-enough to kill all other challenges with scorn? I think not. Therefore, think hard before deciding what you shall do. The truth is bigger than a couple of egos.

Earth twin points his telescope at Earth. And measures how much time passes on his brothers clock as compared to his. His brother's clock is seen to be running slower than his. Thus he Measures time as running slower on his brother's ship

Space twin does a close fly by of the Earth, as he does so, Earth twin uses a sextant to measure the Length of a meter stick on Space twin's ship. he finds that it is shorter than 1 meter. He measures length contraction as happening to his brother's ship.

Do we have to give you a lesson on what Measurement means Also?

It appears that the only one practicing deception here is you; By maintaining the pretense that you understand a Subject (Relativity) which you clearily do not.

Your saying "That is a fact" when it come to Relativity bears no weight because you don't understand the "facts" of Relativity.


Don't make a comment like that. It's provocatively unsupported.

It is amply supported by your own statements which misrepresent Relativity.



You won't budge; will you? I can just 'sense' it. You just utterly refuse to contemplate my ideas as being sensical - despite Ahrkron & Tom both admiting that my ideas are compatible with Einstein's work.

My post was entirely aimed at your misconceptions of Relativity
(which I very carefully tried to correct in the rest of the post) and not your Philosophy.

But since you bring it up.

If you read Tom's and Ahrkon's comments closely, they also said that such compatabilty doesn't mean anything, since there are other valid viewpoints that are just as compatible.

Just like pure Solipsism is compatible with Relativity.( The idea that I am the only reality and that everything else (you included) is just an illusion.)

Or materialism for that fact.

That compatibilty cannot be used to support any of these viewpoints over the others.

LG,

You are being extremely unreasonable here. Janus is providing clear explanations of relativistic effects. He is definitely not lying to the forum.

You, on the other hand, have not understood those explanations and, knowingly or not, are presenting your confused ideas about it as logical necessities. They are not, and I find it upsetting that you push so hard from them, being the case that you know that you are not too clear on the meaning of relativity and Lorentz transformations.

Also, when you say that

You just utterly refuse to contemplate my ideas as being sensical - despite Ahrkron & Tom both admiting that my ideas are compatible with Einstein's work.

you are being deceitful. Both Tom and I mentioned that your ideas are UNTESTABLE, and hence UTTERLY IRRELEVANT to any meaningful discussion.
 
  • #44
Lifegazer, I thought you understood that the observer is always at rest in his own reference frame and that everything within that reference frame appears normal. It is when he measures what's going on in somebody else's reference frame and compares his results with the measurements made within that reference frame that the discrepancies arise. I thought you understood that and I still think you do. For some reason, though, right now you just feel like being a martyr. That's how it appears to me, anyway. Maybe you just aren't reading Janus's posts closely enough, maybe they were worded to complicated. I'm not sure. All I can tell is that I see two people I thought understood at least the basic concepts of something, now arguing over its basic concepts. Frankly, I'm a little lost as to why this is even happening. You read a popular text on relativity. Maybe you need to go back to it.

If the spacetwin can see/experience the fast-clock of his brother, or if the earthtwin can see/experience the slow-clock of his brother, then what you're saying is that each observer exists in his own unique bundle of time, and that a clock observed upon any other object which is moving considerably faster or slower than the observer will not mirror his own clock.
But how can the spacetwin have a 'normal' experience of time if the objects he is looking at (the universe) are all moving much-faster than he would expect?
If the observed-clock is the 'stadium clock' (the game clock, on earth), then the spacetwin will experience the 80 minute game happening in the course of less than 20 of his own minutes, for example. Clearly, all the players on the field of play are running about like Charlie-chaplin, in one of those old silent-movies. There's nothing 'normal' happening here, for the spacetwin. The universe (as observed/experienced by the spacetwin) is all moving several times faster than it would be experienced on Earth. That's the experience of the spacetwin.
So; what price 'normality'? What does it mean?

If the spacetwin observes 'the game' at the same rate as the earthtwin, and yet in less than 20 minutes, then he is not seeing a 'normal' game. He must be observing something which can only be compared to the images we see when we use the fast-forward button on our video-recorders.

It seems to me that there is a valid discussion to be had about the individual experience of relativity, whereby it can be shown that space & time are a function of the observer's own mind (how his mind sees those parameters of existence).

Replace "observer" with "Frame of Reference" and "is moving considerably faster or slower than the observer" with "has a considerable relative velocity with respect to the frame of refernce", and that's about it.

But how can the spacetwin have a 'normal' experience of time if the objects he is looking at (the universe) are all moving much-faster than he would expect?
Everything that shares his frame of reference behaves normally. He shouldn't expect objects in other frames to follow the same pattern. You are trying to expand the use of the word 'normal' beyond what it means here.

Again, you are trying to use the word 'Normal' in a way that it is not meant. Normal is a relative term. It is not the absolute term you are trying to make it. When one says that an observer in a frame sees everything as normal, one means "within his own Frame of Reference" it is not meant to extend beyond his frame of reference like you are trying to make it do.

I find it sad when philosophy degenerates into a forum for debating pet and personal theories based on incorrect or incomplete versions of already established science. Philosophy then becomes like God & Religion, an anything-goes forum, where science can be debated even by those with no knowledge of science.

The philosophy forum thereby becomes a backdoor for non-scientists and those with little knowledge of science to sound off about theories and ideas they barely understand.

This relativity discussion could not take place in the physics forum because the standards there are higher. Many posters would be encouarged to go back and study the basics before launching their theories on the world. You can't just make up physics as you go along. In the philosophy forum, on the other hand, there are few standards and the forum suffers as a result.

I would like to thank the mentors for their patience throughout this relativity discussion.

Do you not realize that a discussion upon these lines (by you) is an enforcement of my own personal philosophy? And if you do realize that, then has your philosophy changed?

I thought I would wait for your debate with Janus and others to die down before answered you. I want to try to explain where I think we agree and disagree, and hopefully get this thread back on track.

Where I sense we agree is that neither of us believe consciousness is entirely the result of material processes. In fact, I can say for myself personally that I know that it isn’t. You may remember some of the debate I’ve had with DT Strain and others where I’ve argued against the concept that all knowing can be empirically demonstrated. It is the philosophy of empirically-oriented materialism that wants to reduce and take everything apart, and sometimes claim if it doesn’t show up in laboratory experiments then it can’t exist. I joined this site specifically to challenge that philosophy, mainly because I’m getting a book ready for a publisher and needed feedback for my concepts. So far the people here have been immensely helpful, even the most crabby and uncompromising materialist types.

What my focus has mostly been at PF are materialist claims I feel are premature given the evidence we have (like spontaneous chemogenisis), and to challenge physical theories of, or involving, consciousness. The latter is the theme of this thread. I don’t think materialist theories can automatically be extended to consciousness, particularly the basic materialist concept that the brain (more or less) generates consciousness. I do believe the CN and brain draw in “something” (potentiality?) and then organizes its undifferentiated nature for thinking, memory, etc., but the “something” beneath all that organization retains its original nature.

As you know, I think when materialist concepts are extended into the realm of consciousness, it seems every time the undifferentiated, unified, holistic aspect is overlooked. Point that out and you might be told such ideas about consciousness have been “dismissed” (by materialist advocates of course), along with notions of the “observer” in consciousness, Descartes, the phenomenon of enlightenment, God and anything else which can’t be explained by, or interferes with, materialist philosophy. I believe it is wrong to ignore or dismiss what can’t be explained by one’s philosophy, and so I want to challenge that.

But just as I think it’s incorrect to automaticallyextend physical concepts to consciousness, so too do I worry about interpreting physical things in a consciousness or spiritual context. I think if there is the sort of consciousness I’ve suggested, or something spiritual, it operates by non-physical principles (though not supernaturally). I am not suggesting duality really, because I see them both as offspring of “potentiality”: but the realms are so differentiated that what defines “physical” functions by its own strict rules, as does the non-physical (even if at the level of “potentiality” they are identical).

So, here seems to be where our philosophies collide because you want to mix principles of physical and non-physical together, and I don’t think it can be done. What happens, whether materialists do it or non-materialists do it, is that neither set of principles is understood. I think you prove physical things through physical principles, and you prove non-material things through . . . well, you know. Further, even the methods of “proof” are different. Empiricism requires sense experience to verify; and then results can be demonstrated to others objectively. But sense experience doesn’t work with immateriality, and one cannot “objectify” one’s personal experience. So “proof” ends up being what each person experiences and proves to themselves alone. This is the second area where we disagree, because I believe you’ve said that you think the realities of immateriality can be proven through reason.

So let’s get back to the theme of this thread for a minute. My point was to isolate conscious experience in the relativity experiment. If you read the posts by those explaining relativity, you can tell they’ve assumed the conscious experience of the traveling twin will find everything “normal” because all physical measurements indicate that. However, the traveling twin had been raised on Earth, say for thirty years, and that rate of time he’d experienced for thirty years was his norm. But while traveling his rate of time was different than how he’d been raised, 1/8th the rate (in my example). This is proven by the fact that upon returning the Earth twin had aged 35 more years. It wasn’t just the clocks that were different, an actual real difference in aging had taken place.

My point is that if consciousness is only a product of physical processes, and because relativity is purely a physical phenomenon, then consciousness should adjust accordingly as rates of time or physical contraction fluctuate. We should indeed be unable to tell fluctuations are occurring because consciousness will “follow” the changes since everything, even consciousness, changes proportionally. However, if consciousness is not fundamentally physical, then it might not be fully subject to relativity effects. I tried to analogize what sort of physical independence consciousness might have with the following:

Say a computer is able to generate awareness intelligent as humans are right now. The computer lives in an entirely electronic world where every device it interacts with is powered by the same source; the computer shares the same power source too. On hot days when air conditioners around the county are straining generators, the power level of computer's shared power supply drops. Now it and everything connected to the power supply slows proportionately; plus, the computer's awareness slows too, and so notices absolutely nothing is different.

A neighboring intelligently-aware computer also lives entirely in an electronic world with lots of other electronic devices. All the devices share a common power source. However, this computer runs on its own generator, and so when air conditioners around the county slow down all the appliances around it, it notices differences in the performance of the appliances, even though its electronic measuring devices (running off the county’s power) indicate all is “normal.”


There is no way to prove any of this since such space travel is impossible now, and probably always will be. My point, however, was to challenge the automatic assumptions of the materialist view that the traveling twin, who takes off used to Earth’s rate of time (obviously if the traveling twin had not lived 30 years on Earth before traveling, then he wouldn’t have any comparison rate of time), will find everything “normal” just because physical measurements tell his senses it is so. I think it is very possible that behind his sense experience the twin’s feeling/intuitive experience will feel the indicated five years of space travel was the longest five years of his life.

I find it sad when philosophy degenerates into a forum for debating pet and personal theories based on incorrect or incomplete versions of already established science. Philosophy then becomes like God & Religion, an anything-goes forum, where science can be debated even by those with no knowledge of science.

The philosophy forum thereby becomes a backdoor for non-scientists and those with little knowledge of science to sound off about theories and ideas they barely understand.

This relativity discussion could not take place in the physics forum because the standards there are higher. Many posters would be encouarged to go back and study the basics before launching their theories on the world. You can't just make up physics as you go along. In the philosophy forum, on the other hand, there are few standards and the forum suffers as a result.

I would like to thank the mentors for their patience throughout this relativity discussion.

It's no sadder than opportunistic scavengers waiting for occasions to act superior.
