Is it possible to build a time machine through the use of programming?
 |
The only time travel that programming will support is uni-directional - you will be older when you are done. There is nothing in Einstein's General ToR work that implies time-travel and everything in Special ToR that explicates that time-travel is impossible. The Einstein-Rosen Bridge predicts wormholes because Albert could not stand the idea of a singularity in the center of a black hole - Wheeler discovered that the Einstein-Rosen bridge space-time structure was dynamically unstable in field-free space. They showed that if such a wormhole somehow opened, it would close up again before even a single photon could be transmitted through it, thereby preserving Einsteinian causality. This lead to Lorentzian wormholes and Euclidean wormholes but I digress.
I would look more towards Feynman - "It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong."

Imagine a world without hypotheticals....

Listen, time travel is possible, this I know. I travel back every time I think of playing in our huge chestnut tree as a child. Every time I remember my Grandfathers hand touching mine as he passed me a dollar and said " here, go buy yourself a couple cigarettes or something" while smiling at me with such sarcasm and love. Every time a memory passes through the polarized atoms of my brains neurons.
Ok, but seriously, time travel is not impossible in my opinion. We can see the beginning of the universe if we produced a perfect source of magnification. Enough that we could view billions of light years into space. And even then, if it were possible to view back at ourselves through the curvature of some light rays as they pass by a black whole, we may be able to see ourselves years before but never create a wormhole and survive, or even produce a machine to pass the speed of light in a sphere around us and survive.
I think our time machines, my friends, will be for now and forever, in our memories and the stories or our elders.
BTW, a great movie about time travel and one of my favorite movies is Time Machine (2002). You should check it out.

An eye for an eye and the world would be blind.

Hehehe, retarded eh! But you could never deny that most of you has been always intrigued about time travel... If you weren't intrigued about Einstein's theory then why did you replied to this thread, hehehe... you really can't deny it.
Imagine if you see your past self or future self.... HAHAHAHA Still RETARDED thing to think of!!!
If you have not read [U]All You Zombies[/U] by Bobby Heinlein - do so as quickly as possible - it is the end all and be all fo Time Travel stories. All the characters in the story are the same person; he is both his own mother and father - the bartender, the time traveler, the sargent of the guard and when he closed his eyes, he was terrified that the universe would go away. He knew who he was but - who are 'all you zombies'.

Thanks Ancient Dragon! You're so cool! With this, we might solve the problem of Einstein theory... a little bit... hehehe we still don't know how to bend time by using this codes... there are still several problems we will possibly encounter...

If the universe is deterministic, it'd be possible to simulate forward progression of events and have it exactly correspond to actual progression of events. If it's deterministic & time invertible, then it'd be possible to simulate backward progression of events. Provided that the simulation exactly corresponds to the entire universe, in every detail.
Not then, for a person to travel forwards and backwards, but to to create an identical copy/'image' of the universe and run it backwards and forwards at whatever speed desired. Of course, such a system would necessarily take all the matter and energy in the universe plus some* to implement.
*infact, multiply some.
So, if my pre-requisites hold, then it's theoretically possible to at least gather data about the past and present, just totally infeasible.
Paradoxically, if the universe truely is deterministic, it wouldn't be possible to act any differently (i.e. to 'change the future') regardless of the outcome of such a simulation; since doing anything 'differently' would violate that determinism.

I think these people have been watching too much Star-Trek, where the computers run in the future then bring back the result to the present so that it appears to do its stuff instantly.
Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.
At least... for now, all the technology that we are using would have a very much much more better, and a very absolutely worthy to die for purpose.
We might get a very very tiny specs of ideas from every technology that we are enjoying as for this moment in time. Like the concepts that are used for DVD players, we could rewind, go forward, and stop. Or could you get any other ideas how to solve it? Everyone, you might not see it but we are helping the great genius Einstein solve the problem of his theory. You might not be aware of it but each one of you is finding a way how to solve this theory. You may think its funny but just notice how destiny drives us here, in this rendezvous of fate...
We might see someday and fulfill these purpose... all of us might see someday... to build our very dream... to build our very dream...
