Proving the Existence of a Future

In summary, there is evidence of the past in the form of fossils, architecture, artifacts, and culturally modified trees. However, there is no concrete evidence of the future, only predictions and assumptions. Memories are not proof of the past, as they are constructed and can be tampered with. The past is a state or condition that is inherent to the present, and potential exists as long as there is a probability of it happening.

"Future events" are not the same that "future". We are moving to future at speed 1 sec per sec. But the lower border of future is moving away from us at the same speed. However "future and possible" events are not moving in time, they are waiting for us.

Everything you wrote here is great. Could you please explain the last bit I've quoted? In what way do future events "wait" for us. I know this is an anthropomorphic way of putting it but, perhaps you mean "future conditions" are predictably going to be the same as they are now so they will occur when we experience them in the "future present". That is, of course, if you take uncertainty out of the equation.!

Of course, if future events do not have their own soul and will, they actually do not "wait" for us. They even DO NOT EXIST, before their time come. It would be better to say: WE waiting for them or we predict them, etc.

baywax said:

It depends...
The "future conditions" MAY BE predictably going to be the same as they are now, for example oceans, large mountains, planets.
But they may even NOT exist now. If the "future event" is COLLISION of two cars on the street, then the event (COLLISION) does not exist yet, however cars and street already exist.

Actually, everything in the last bit you've quoted is easy.

#1. There is a coordinate, time, "t"

#2. "Future event" may have coordinate, for example "Feb 15, 9:00 AM EST" This future event does not move in time.

#3. We have coordinate "t". We move in time. Yesterday our time coordinate was "Jan. 21 ...", today it's already "Jan. 22 ..." and we expect we would enjoy coordinates "Jan 23", ... "Feb. 15" etc.

#4 "Future" has coordinates from "t + epsilon" to "t + epsilon + delta". Its lower border is "t + epsilon". We are moving at unit speed, dt/dt = 1. And the lower border of future is moving at unit speed d (t + epsilon) /dt = 1

#5 We may cover a large interval in time, like 50 years. But we cannot cover interval from "t" to "t + epsilon". That means "Future" never become "Present". "Future" is always future.

Would this be the same inductive logic that proposes the universe was created by a superior being since there is no proof that a superior being did not create it?

Inductive reasoning doesn't propose anything.
If you think it does, you don't know what inductive reasoning is.

If you think inductive reasoning doesn't result in the proposition that a general rule can be formed by making a generalization from specific cases and "formulate a general rule after examining a pattern" then you don't know what a proposition is or you don't know what you're talking about.

People formulate rules using induction. The fact that Omar the crazy homeless guy down the street uses induction to show that pink unicorns exist doesn't mean that induction proposes it. Inductive reasoning is a method.

Once again, thanks for wasting my time. I should know better by now... of course.

Here's what I have so far on the "Wheeler/Feynman Absorber Theory and the Radiation Arrow of Time" .



http://www.phys.cwru.edu/undergrad/Senior%20Projects/SeniorProjectPosters/KevinEngelPOSTER.pdf

What does "direction" have to do with "time"? The radiation arrow of time describes how all waves of energy radiate out from the source of "work" or "energy". So here the direction is "out". However, we can only observe this in "real time" or "the present". So, how do we derive "the future" from the presently observed direction of radiating waves (which radiate in every direction)? And, are we certain that the waves are not radiating "inward" as well?

However, the Arrow Of Time does appear to hold a promise of proving that there is a future because it demonstrates that there is "room" for waves to radiate or for a cup to shatter into pieces... in a direction that will not be spontaneously reversed or is "asymmetric". The "room" to propagate motion is what may be able to be seen as the "future". Or... can we call it "potential"?
Feynman discussed this in one of his Cornell lectures (used to be on the web). The point was as stated here that most all of the fundamental laws of physics hold whether time runs forward or back, but that effects that are now commonly called 'emergent' run in only the forward direction, diffusion or the coffee cup being examples of emergent behavior.

Hello to all,

Again, the most interesting topic of time comes around… here’s some adlib of what comes to mind at this moment ;

As humans we are not aware of time itself, we can only experience it subjectively as the ever flowing present. We are aware of duration, from which we created an objective reference segmentation, the second, that we ‘inflate or deflate’ to use in our daily lives.

As far as proof that the future exists, it most certainly would have to be found in the present. Furthermore, in order to be complete and accepted, the validation of this proof has to be done in the presence of both our subjective and objective representations of time.

We have to start by laying out the rules of an experiment that will bring forth, from a subjective present referenced objectively as t0, a positive and reproducible solution that can be used as proof, in another subjective present, referenced objectively as t1, that future exists. And you know what, this kind of proof is experienced over and over everyday by everybody. Throw a ball in the air look at it long enough and you will see it come down and bounce. You can repeat this as many times as you want, it will happen in the same manner over and over. So you could certainly say to yourself that “if the ball comes down and bounces after I throw it up in the air, future exists …”, of course, if a bird happens to pass by and grab the ball, then you’d be out of a proof, but that’s not the point.

Here’s one possibility in a controlled environment;

We dispose of a gas source and several inflatable balloons that can be attached to the source in order to be inflated, the source’s output is at a constant flow and the balloons are identical, holding the same max pre-burst volume.

The premise of the proof is that if, after a balloon is hooked-up to the source, and that, at our subjective present t0, flow is started, we observe the balloon inflate, become larger until, at our subjective present t1, we see (and hear) the balloon burst, then future exists. End of experiment.

The burst is the proof, reproducible, both subjectively and objectively.

I mean, I know this all naïve, but what more do you want? Only the ever changing present is experienced, past and future are in the abstract realm and are contacted through our spiritual selves where there are no proofs needed.

Forward in relation to what?

What I don't get is, sure you can have left and right, backwards and forwards and clockwise and anticlockwise but all of these conditions are relative to the observer. If you've ever been inside Big Ben (large clock in London England) you will see that it is running anti-clockwise. Then, you get outside on the street and its running clockwise. Its a typical example of relative point of view.

Similarly, forward and backward are relative to a stationary observer or to the observer that is in a specific direction of motion. The perception is that they are moving and that they are leaving something behind. The reality is that they are experiencing many different states and the perception of a succession of states evokes the sensation of motion and forward movement.

I require a definition of "spiritual self" before I can comment on your otherwise engaging definition of time etc (is the "spiritual self an induction like the "future" and "Satan"?... Also... the "t0 and t1" are arbitrary tags placed by yourself. I don't see them on the balloon or a train approaching and leaving. The multitude of states that create the phenomenon of the doppler effect or a bursting balloon are what give us all the impression of succession and sequence. The reality is that these states are all acting at the same time to give us what we call the present.

In keeping with your comment I tried to say to myself that the present is the proof we have of a future. But I'm still trying to justify this idea.

This succession may be parameterized by a variable "t".
"t" belongs to an open interval (T_birth, T_now).
We are at the boundary point "T_now".
There is NOTHING yet on the other side.
We extrapolate this interval and believe our extrapolation is correct.
We even do not predict exactly what will happen.
We just predict that SOMETHING will happen.
That is enough for our happiness.

Actually, a possible THEORY OF TIME may be based on one of the postulates:

Future already exists, past still exists, but our perception is limited only to subspase t = t_our.
This is a theory of a localized observer.

OR

Future does not exist yet, past does not exist already.

OR

Future already exists, past still exist and MY perception is not limited to subspase t = t_my.
This is the theory of the distributed observer.

Hello baywax,

t0 and t1 are of course tags that need to be put there in order to keep track of the portion of objective elapsed time during the experiment. I forgot to mention about the clock that is used to measure the difference between t0 and t1, being the duration of the whole ‘succession of states ‘ as you put it, that lead to the bursting.

Now, it is plainly obvious that observing a succession of states gives us the perception of time flow, but could you please elaborate on your claim that they all act at the same time… I mean, how can you put ‘successive states’ and ‘at the same time’ together in the same sentence? …the train cannot be 1km away and passing me by, nor can the balloon be deflated and on the verge of bursting, all at the same time.

What do you mean by acting at the same time ?

When I use the term spiritual, it’s meant in its nonmaterial aspect, not induced and certainly not religious related.

What I meant when I said successive states is that we perceive states to take place in a sequence. The balloon is empty of air then we perceive it to expand with air then we perceive it to burst. Each of these states, however, takes place in the present and, for all intensive purposes, at the same time... because they all take place in the present. We only have a memory of the "sequence". I would argue that memory is an adaptive development of the brain that facilitates our survival a little longer than, say, algae, which has only instinct which may or may not be based on its own genetic information.

I'm very sorry, but "we" do not distribute an observer. An ant cannot play with an elephant. (But an elephant can play with ant :wink: )

OK, well...

There are observers distributed along commonly known in special relativity world lines. We call them T-distributed observers. (Actually they have a limited distribution in space as well... about a few feet, or about billions of light years, but this is not important) They have practically unlimited ability to reach past and future, but space only within their world lines or world cylinders.

And there is the observer distributed for example over whole (3 + 1) space. You understand that in a given (3 + 1) space there is only one such observer. In another (m + n) space there is another (m + n) distributed observer.

How about just setting up cameras along the path of action/motion? The observer can be anywhere as long as they have a multi-monitor strapped to their head, receiving every phase of the motion for the observer. This set-up would closely simulate the type of "present" I'm trying to explain... where there is no sequence but only a probable "state of sequence" which is one of an infinite number of other states.

I like your model. It may be considered as a first step in understanding (if that is possible for human to understand different creature) what a T_distributed observer may feel about time.

But there are differences between the simulated_by_you and the real T_distributed observers.

1. The real T_distributed observer may reach ALL values of parameter "t" from minus to plus infinity. Your observer only from "T_when_cameras_installed" to "T_now".

2. There is a natural parametrization of external (from monitors) events. For example, let it be dates of January 1,2,3,... 29, 30, 31. Your observer may change the order what watch first, what watch next, like 29, 15, 7, 10, 12, 5...5, 5, 4, 3, 5, 5, 1, 5, 2 (note repetitions of "5"). That means he escaped from external "past_present_future" jail. But instead of external time_jail he created his own internl time_jail, which is his new parametrization. In this new time_jail he has:
The Past: 29, 15, 7, 10, 12, 5...5, 5, 4, 3, 5, 5, 1, 5,
The Present: 2
The Future: Any possible combination, he may wish, from the set 1 to 31.

So, until your observers with monitors has human_like sequence of perceptions (one by one), he cannot actually escape from "past_present_future" time_jail. He may just reorganize it by reparametrization. He may destroy EXTERNAL jail, but he still has his own INTERNAL "past_present_future" jail.

True.

The Cubist movement of artists got around this by springing their paintings from the "jail" of time, distance or positioning coordinates. They used vantage points from 360 degrees around their subject and combined them all on the canvas. So here, the subject is shown from every POV at the same time. This could apply to the perceived transition of time between birth and death as well. As with any painting, their presence is immortalized in imagery. In Marcel Du Champes' "Nude Descending the Staircase" you see each position of the model depicted at intervals in the piece:

http://www.udel.edu/psych/johnmcl/nude.jpg

If you add distance to the method of diminishing sequence etc... you can see another method of transending past and future. Take, for instance, two different points of view separated by great distance.

In one POV the person is in the centre of a city with no idea of where streets lead or what is where. The other POV is in space and the city is one dot on the planet. The dot represents large amounts of time, space, activity, energy etc... but the representation is severely diminished at a distance. It is, in reality from that POV, a dot with no motion, no sequences, no distance, no passage of time... on a spherical dot in a vast ocean of space.

The same brain receives all the perceptions at once.

T-distributed observer:

“What do you consider the future …. Its just a word and a feeling an uncertainty. The future is what you make that’s of life I am responding to something you rote in the past . You can travel to the future you do it every second we are doing it now as I type this I am on my way to the future and the next word I type will be in the future one could assume that you could travel to the future by preserving your body and waking up in the future but then it would be the present and you would feel know different someone who sees the future is just someone who can see what's gowning to happen next

Once there was a book written from a church steeple looking down on a village the man could see things before they happened a man and a woman walking there dogs down two different streets that met at a corner he knew that they would meet and the dogs would bark but they didn’t . is this seeing the future its for u to decide but let's just travel time this way come join me on my time machine we move constantly towards the future and have fun on the way come one come all I will watch you gather from the roof of my house seeing the future as you come.”

We don't even know* that entropy will continue to increase forever. The universe is currently moving towards thermodynamic equilibrium from the Big Bang, and it's possible that one day it will start moving away from equilibrium again towards a Big Crunch.

What will happen if the Second Law reverses? Well, all our biology would fail, we wouldn't be able to think or record memories, and time as we know it would end.

So the end of humanity, in theory, could be like a lightswitch clicking off when we least expect it.

*=Hawking thinks he knows entropy will always increase. But it seems theoretically possible that it won't, so I won't be convinced unless he can put across a good argument.

In keeping with your comment I tried to say to myself that the present is the proof we have of a future. But I'm still trying to justify this idea.

Well, late last night, coming back home during a 3 hour drive, I was thinking about lots of things and a kind of revelation came to me about this particular thread and your quest for a proof that future exists...


You are quite right in saying that the present holds the proof... I'll try to be as succinct as possible and maybe post again on it, but for now, here it goes...


Life on Earth IS proof that the future exists and as humans we stand in an utmost privileged position, being witnesses of, as well as part of, this proof.


Everyday we can observe our world being bathed by the Sun's life-sustaining radiation coming from the past, after about an eight and a half minute journey, finding its future in Earth’s present.



Now, it’s interesting to apply this thought to a beautiful star lit night sky… but no guarantees being provided, we can hope to have at least an eight and a half minute future and, if predictions hold, humanity can push for about 5 billion years on top of it.

That's the romantic way to put it! There's a lot of faith involved in the view of "living in the now" because you must have faith it won't end and you must imagine it "unfolding", like a flower etc...

On a dryer note, I came up with something along the same line...

The present is, as so many have observed, the "crossroads of the past and the future". They say this because they believe there is a future and because they're propped up on the bones and garbage of the past.

The truth in the "crossroads" statement is that the present is proof of the future because it represents that very "unfolding" of the romantics. The present is the manifestation, the representation and the actualization of the future, however long or short it may be. And the proof is that we are experiencing the future...now.

But I have neglected a large portion of thoughts about the future and so on... and that's the "Eastern" frame of reference when it comes to "time' and past and future.

I'd like anyone with some time to further educate us on those "Eastern" thoughts about the future. Do they have proof of the future... do they believe there is a future. Or are they blissfully only aware of "the now"?

I'm going to bypass the more philosophical comments, since I think they don't really accomplish much, but the above is worthy of note:

We know that nothing with mass can travel as fast as light and that nothing without mass travels faster than light.

This would include the event of oblivion. By oblivion, I don't mean something metaphysical, I mean the actual, physical cessation of matter and energy from the universe.

It can't travel faster than c. so even if the universe somehow ended, it could only propogate across the universe at best at the speed of light.

Hello Dave,

exactly, and that would take a lot longer than our Sun's projected end of life at 5 billion years.

But then again maybe the universe has already terminated and we'll see the result before the sun shuts off ... maybe not...

By the way, could we 'see' this end coming at us, with any means we have to scan the universe, or would it be sudden ?
