Time travel is deemed impossible due to logical and physical constraints, with no evidence of future travelers visiting the present. The discussion highlights that if time machines existed, one would expect to see visitors or devices from the future, which has not occurred. Arguments against time travel often cite violations of causality and quantum mechanics, while some suggest the possibility of traveling to parallel universes instead. The conversation also references Stephen Hawking's experiment, which failed to attract future time travelers, further questioning the feasibility of time travel. Ultimately, the consensus leans towards the idea that time travel, particularly to the past, is unlikely to ever be realized.

You say you move the "birth" and "death" positions of the salt crystal to new locations.

And every temporal (or spatial) point in between.

But, why does the time machine care about your concept of the crystal being "the thing" to move?

Because that is the defined object to be moved. If I pick a sugar cube out of the sugar bowl and put it in my tea (spatial movement) I do not care that this sugar was once sap in a plant or a liquid in a sugar factory tank or that it touches the side of the bowl or other sugar cubes.

But I still move the whole cube, not a part of it.

Consider this experiment.
I have a stack of blocks on the table.
I remove one of them and place it by the side of the stack. ( a spatial movement )

If it is the top one there is no further disturbance in the universe (spatial consequences)
If it is the bottom one the whole pile comes tumbling down and there are spatial cause and effect consequences, because there are blocks depending upon the bottom one, but not the top one, for support.

There seems to be an argument which runs that a temporal movement of the block will create a paradox ( temporal consequences) therefore time travel is impossible.

I am simply saying that if a block is moved in time or space there may be cause and effect consequences. However the time axis seems to be jam packed full, compared to the space axes where it may be possible to arrange movement without consequences. Perhaps we could posit a totally isolated block that could be moved in time with no effect on the rest of the universe?

This is the pont I was trying to make using PEP, Studiot.

Every particle has it's place in the universe and in history. If anything went back in time it would go back to where it was at that time.

If one were to travel back in time one would not be aware of it, as the future would not have happened yet.

I like very much the theory, but I have a question...
Does anyone start trying some kind of electronic test? I say you that because I have some books (some of them very old and very rare), that describes theories about the matter, time, etc...
My question is if someone want to collaborate with me into replicating these experiments and working together in the development of the devices.

The first experiment would be a device to alter matter using radiations. Basically it consists in a non-hertzian wave generator (potential waves transformer), a circuit and a computer program to measure the composition of the object through resonant properties, and a "spark gap" to put between the object we want to be irradiated. This is absolutely experimental and it requires some knowledge in the electronic field.

This completely fails to grasp the very concept of time travel.

This is an utterly philosophical belief of choice, bereft of any physics-esque teeth.

It is also tautological. 'Time travel is impossible because I've defined it in a way that says time travel is impossible.'

Ash Small said:

Why? Time is a dimension. I can go from y to y' and back to y again. We are simply talking about going from t to t' and back to t again. No one said x or z have to remain fixed in either case.

Ash Small said:

That is not time travel.

If one goes somehere, by definition, one takes one's mind with one.

Consider the analogy to traveling back in space. If I go to the cottage, do I only have with me the things I brought last time I came back from the cottage? No. A change in direction does not imply an undoing of the previous direction. This trip to the cottage is with the current me. I have new luggage in my trunk and new tires on my car.

As it is with time travel, I travel in time, meaning I bring all my current thoughts with me.

Dave, I appreciate the points you make, but consider this:

If you travel from (x,y,z,t) to (x',y',z',t'), you pass through every point on the x-axis between x and x', similarly for the y,z and t axes.

If you then take a different route back to (x,y,z,t), you again pass through every point on each axis between (x',y',z',t') and (x,y,z,t).

When traveling along the t axis you either get older or younger, depending on your direction.

You cannot travel along the time axis in either direction without your age changing.

If you are getting older you are traveling forwards in time, not backwards.

This is not true.


If I travel West 10 miles, then East 8 miles, I personally have traveled 18 miles (and so has every aspect of my car), even if to an outside observer it appears I have only traveled 2. (The observer does not see gross distance and duration of trip, observer only sees net result).

If I travel 10 years into the future (at 1 year per year, like everyone else does), then travel 8 years back into the past (at 1 year per year), I will be 18 years older, not 2.

So that even if I travel 8 years back into the past taking only 8 seconds instead of 8 years to do so, I personally am now 10 years+8 seconds older.

Dave, That's like saying if you run five miles every morning and five miles every evening, after two weeks you'll be 140 miles away. (this is not the case for any of the joggers I know.)

If you travel 10 years into the future then 8 years into the past you will only be two years older.

We both have a different opinion here. How do we ascertain which of us is correct?

Quote from Dave
...despite the fact that it's a one-way trip in time.

If you let 100 years go by while you take only 6 years to travel to Gliese 581, all your loved ones are dead forever.
It is important to keep in mind that there is dilation in only one direction. You can slow time via GR but you cannot speed it up. Free space, away from massive bodies is the fastest time is going to travel. Moving into a gravity well will slow time for you, but there'e no counterpart. There is no flatter space or negative curvature.[/QUOTE]

Having given this some thought, I think that according to what you have said above that there may be the possibility of a return journey.

I will re-itterate my idea in the interests of this posts coherency...

On the basis that time is variable according to gravity intensity, I can see that "a" concept of time travel could be realized in that slower time may be created IF gravity could be controlled.
When traveling in very fast time/gravity variables, such as found in outer space, in a slow time/gravity controlled craft, to spell it out, your time would be happening at a much slower rate than time outside the craft.
On the basis that there is no "flatter space" or "negative curvature", could the possibility of an all the way round trip exist?
If your time on the craft were set at a slower rate than Earth's time and the rate, or rates, that time happens at in space were known, a clever mathematician could theoretically navigate the craft in a "round trip" back to Earth not long after it's departure without the need for anything to be in two places at the same time and one's loved one's would still be alive.
The crafts speed would be a factor in these calculations.

There is of course the considerable problem of controlling gravity. As my input to such a discussion would be zero, I realize that it would be unfair of me to ask anyone else to embark in such and will now leave the subject alone.

Thank for the link, I'm reading it and at the moment I have found it interesting.

The problem with serious discussion about time travel is that we need to understand in other way to understand how the universe works. People that have studied in university use the classic point of view of science, valid, but incomplete to fully understand the time travel physics. And the people that haven't studied in university cannot fully explain physics in a correct way.
So, what happens? People with an university degree have a classic, proven, point of view about physics and usually they don't want to believe in these kind of "para-physics", because almost always this non conventional point of view is rated as esoteric science, pseudoscience, etc...
In the pseudoscientific world there are a lot of charlatans, of course. For that reason, pseudoscience is classified as a non-sense way to understand physics. But the true key is that someones in the pseudoscience world seems to be right. But they are very little known. So, speaking about time travel could be like trying to find a needle in a haystack.

I whole-heartedly agree with you statement above and would like to add:
Early man encountered many round things before a slight change in perception and perspective in the way of looking at these things brought about the advent of the wheel.

Do you know what displacement is in comparison to distance travelled? If I run five miles to work every morning and five miles home every evening, after a week I will have traveled 50 miles in distance, however I will have a net displacement of 0 miles.
If you travel 10 years into the future then 8 years into the past you will only be two years older.

If you travel within a time machine, your own personal timeline isn't affected by the changes in time around you.

If you have a time machine and travel 8 years back. Everything outside the time machine will become 8 years younger, everything inside remains at their current age plus the journey time. This is the concept you aren't grasping here. This is what people mean when they say time travel (reference: any movie involving time travel).

Personally I think the field is wide open for all kinds of time travel. Using a (theoretical if only gravity could be controlled) slowing of time in the craft, one could control how much older one became on the journey.

Well the larger the gravity field the slower that time passes. But on the flip side, the higher the gravity, the less likely you are to survive.

All kinds of time travel? Maybe. But we are discussing a time machine. A time machine where your age (inside the machine) changes exactly the same as everything outside, is pointless.

O.K. You got me there. The definition was indeed a "Time Machine" and from the OP as well.
I shall busy myself now with trying to figure out how to "create time."
Don't expect a timely answer on that one.

No change on the "creating time" project, but just to ask did you actually read my method of time travel post? Because what I was suggesting (not withstanding the considerable gravity control problem) was that one's age would stay at the same rate or perhaps (taking into consideration intensity of gravity survival rate) slightly slower while everything else went past very quickly in fast time/gravity variables, out in space.

I haven't, if you point me to it I'll certainly have a gander at it.

I must say, the whole "body ageing normally whilst time goes very fast outside the craft" premise is basically traveling really fast. No gravity involved.

If I travel at 0.99C, time to me would pass 'normally' and I would age as per usual. It would take circa 8 years to reach proxima centuri and come back. However, to those who remained on Earth it would have been significantly longer. So, put simply, I aged (and lived) 'normally' wrt my time frame, and it went quickly outside of the ship (from my perspective).

Really? Ask your jogger friends how many miles they've jogged - how many miles of jogging they have actually experienced in that two weeks.

Do you think they will say 0? Or do you think they will say 140? You tell me.

Time travel is about what the individual doing the traveling experiences on their journey.

You go to space in a normal craft and time is moving fast, so fast that your loved one's are dead when you return.
You go to space in a gravity controlled craft using slow time, you come back and your loved one's are alive.
Now what is not time travelish about that?
Goodness gracious how I wish I could do maths!

P.S. It's like there's the numbers, I can see what needs to be done, (I think) I just don't know how to do the sums.

The problem with serious discussion about time travel is that we need to understand in other way to understand how the universe works.
Yes, but huge sweeping changes to the geometry of space isn't what makes a "new way to understand." Very tiny changes to fundamental understanding has dramatic effects on the rest of physical understanding and by the very fact that what we do know is already really accurate, it is the case that even tinier changes are what we should be looking for.

People that have studied in university use the classic point of view of science, valid, but incomplete to fully understand the time travel physics. And the people that haven't studied in university cannot fully explain physics in a correct way.
Your statement reeks of begging the question and besides that is nonsense. It even has a hint of presupposing that people who don't know university physics are somehow better in some way (this really makes no sense).

So, what happens? People with an university degree have a classic, proven, point of view about physics and usually they don't want to believe in these kind of "para-physics", because almost always this non conventional point of view is rated as esoteric science, pseudoscience, etc...
No, that really isn't it. It's just that, if your idea looks like poor or commits logical fallacies it will be called on those things. You'll notice that no one ever straight up rejected your notions, but simply explained it as "It doesn't work like that." Know why? Because it doesn't work like that. The thing with these new and radical ideas is that the authors dive in with all the confidence in the world, and a really odd and deep-seated assumption that what they are saying is right. There is no concern for the truth of the statement, no effort wants to be spent in understanding what really is. Ultimately, there is no humility. It's as though these authors unassumingly believe that they're right and the dogmatic experts are wrong.

In the pseudoscientific world there are a lot of charlatans, of course. For that reason, pseudoscience is classified as a non-sense way to understand physics. But the true key is that someones in the pseudoscience world seems to be right. But they are very little known. So, speaking about time travel could be like trying to find a needle in a haystack.

"Someone in the pseudoscience world seems to be right."
REALLY? Well gosh mate, someone in the REAL science world seems to be right. What now?
These kind of paraphysics include:
Quantum electrodynamics, vorticular physics, quantum numerology, vibratory chemistry, hyperdimensional physics, unified field theories, etc...
Another obstacle is that is very difficult to find information about these fields. The little I know, I have learned reading books in 5 different languages since 1920 to the actuality. And I have found very little amount of books. And you need to know about chemistry, physics, electrical engineering...
Almost an impossible task to achieve.

... you think QED, and Unified Field Theories are paraphysics? You even put QED and UFT next to something called "Quantum numerology." Nope, not even close.

The only way is to read all kind of things with an open mind, get the points in common that the information has and put in practice very simple experiments. The only experiment I've proposed, is to interact with matter using non-electromagnetic waves, aka pure potential waves.
With this experimentation, it could be possible to learn how to affect matter with electrical currents. And, understand than materialization and dematerialization could be possible.
I've also some books in Italian that explains how to access to the memory of solid objects, reading past events.
To those who find the following points in opposition to what they think:
You terribly missed the point as to why I posted that link. To have a serious discussion regarding time travel (or anything) we must all be speaking the same language. Otherwise, too much is lost in semantics and in understanding what is already well accepted. Good arguments and thus new discoveries, be they conventional or not, must ultimately and unfailingly break down into a series of trivially true statements (be they mathematical in nature, or not). If we don't understand mass, and electromagnetism, etc. in the same fashion then it might as well be the case that we're not even speaking english.

So, I posted those links to show you guys what the experts are saying. If we're going to try to understand time travel in any such way, it's best for us to speak the language of the people who have thought about it the most, and have been the most thorough. These people have really followed each concept through to its logical end, especially the basic ones we have been discussing here. It's their life, they do it 40+ hours a week.

One more thing, I really want to stress the following point: Being non-educated in physics does not make you open-minded or better in any way (seriously, why should it? If I don't go to art-school am I better at drawing/painting than an artist? If I don't major in history, am I somehow made more aware of historical fact?). Creativity is a property that belongs to the individual, not to the profession. If you take a creative person and teach them physics - do they all of a sudden lose their creative nature? No, of course not, that'd be absurd.

If you are going to do physics, at least make an effort to understand the arguments that already exist, and why they are explained in the ways they are, this is the beginning of developing a keen understanding of a field that you seem to be interested in. Not knowing, making a mistake, these are all part of the process of learning and they should be accepted and welcomed. Science isn't about speaking the most amount of jargon or discussing the most esoteric of ideas, it's about understanding a spinning top or the steam on my windows, or the green on the plants. It's simple, and it's about observing and understanding.

To Magnethos and Time Machine

Brin, could I please disassociate myself here. You have used my post to quote Magnethos. It is my fault for leaving too much of his original post in mine, I do admit. Let me clear this up. I agree with Magnetos in that he says that everybody has something to offer despite the origins of their knowledge. I do not know about metaphysic's. I was going to look it up, but had to go to work. The only thing that sprang to mind was deja-vu.
My addition to the post concerned "the advent of the wheel". A valid comment when thinking about adjusting one's perspective.
I have huge respect for established physics, a subject I find compelling.
 
  • #147
I removed both yours and Magnethos's name, and even though we mention them here, the arguments above are irrelevant as to who I am talking to. I think they stand OK in isolation, though I look like a rambling mad man. I also suffer largely by going off topic. I hope the moderators will just see it as a note that I am defending my post with regards to time travel.
 
  • #148
I was discussing this topic with my friend, and reached this conclusion:
Time travel is impossible because of three reasons:

1. You cannot be dead and alive at the same time (unless you're the cat in the box)
If time machines exist, they can surely send video signals back in time. Therefore, if you put a CCTV beside your friend, go back in time with the cable, and plug it in in a TV of the past, watch your friends actions in the present, and kill your friend in the past, your friend will be dead and alive at the same time. The camera excludes the "Schrodinger's Cat" proposition.

2. The Law of Mass Conservation
If one molecule of gas goes back to, say, 1990, team up with two molecules of gas and goes into the time machine in 2010 back into 1990, team up with four molecules and goes into the time machine 20 years later, and so on, the mass of the universe will go up indefinitely.

3. Strange paradoxes exist
If you are about to detonate a bomb, go to the future and dismantle it, get back, and detonate, will you see yourself go dismantle it? If so, what if you detonate just a bit faster and destroy your future self? Will you teleport a moment later into the explosion? Probably not.

It's like you and your friend didn't read the thread. There different types of time travel theories, some fail some haven't been defeated yet.

You haven't given any definitive reason as to why time travel in general is false.

Note that the parallel universes version of time travel still survives your theories.

I.e. you can't travel backwards on your own timeline, but you can travel sideways to timelines like yours, until you find a timeline like the one that shows your past. In this case, you gruesome acts of violence and conservation theories don't really challenge anything other than the local law.

There are a number of hypothesis which circumvent this issue and make time travel possible. So far as a "cable back to the past" goes, that would require a system which allowed the cable to occupy a set of points from present to past. Whether that is possible, let alone would work I am not sure, but the premise sounds wrong.
I suppose you could record a dvd now and take it back to 2000 and show it to the person in it. But again, there are a number of hypothesis which allow for this so it isn't a certainty that it would prevent time travel.
2. The Law of Mass Conservation

Not so, if it goes back to 1990, it does not exist at 2010 anymore (instantaneously). From 1990 to 2010, yes, there would be an additional particle in existence, but once the point at which you send the particle back is reached, the balance is restored. You certainly haven't 'created mass'. This may create some problem with the maths, but it doesn't write off time travel.
3. Strange paradoxes exist
If you are about to detonate a bomb, go to the future and dismantle it, get back, and detonate, will you see yourself go dismantle it? If so, what if you detonate just a bit faster and destroy your future self? Will you teleport a moment later into the explosion? Probably not.

As per point 1.
