Time travel is possible into the future. However, you can't go back in time farther then where you started from when traveling into the future. And of course, the sheer amount of power that would be needed to open the wormhole, make sure its at the right spots, and open it wide enough and for long enough to pass through and come back later are astronomical, and beyond our tech right now. Also, yes, this stuff is mostly correct, it stems from string theory, which is mathematically completely proven, but still untested experimentally due to us lacking the tech to do so. However, it is the new supercollider in Switzerland that could yield the first proofs. See, string theory says there are 11 dimensions, and gravitons, the particles that create gravity, are multidimensional in their ability to affect matter, but single dimensional in where they reside. It is believed that by using the LHC, we can pull those particles into our demijohns, at least temporarily, long enough to see them. If we can do this, it is a MAJOR proof of string theory.
Check out the book and documentary "The Elegant Universe" and the sequel to the book "The Fabric of the Cosmos."
Here's a better visualization:
Each of those points would actually be on every single point, which are infinite, of course. Curled up into each point are the extra dimensions, in which other particles, gravitons included, reside. We pass through these dimensions every day, every time we move, but we don't actually feel it, as they are so minuscule.
I did know, it was possible to travel into the future, theoretical. Never knew much about the string theory (i never was a big fan about the shear amount of dimensions needed, but in way it makes sense).
I always thought that the whole search for the gravition was to unify all the basic forces in nature, in which gravity always was an exeception, into one theory. To prove that even gravity is driven by subatomic particle interaction.
Actually, the problem with unified field theory was that you've got quantum mechanics, and general relativity. The former deals with small stuff, and later with big stuff (big stuff being anything above the quantum level). The problem is, when you try to unify the mathematics and theories, it doesn't work. String theory brings in the extra math and models that are needed to unify it, which is does perfectly. The problem is experimentation on it, which we are getting closer and closer to being able to do.
I watched this video a few weeks back. I see the way it strings it all together and makes logical jumps to get to the next dimension. It actually helped me understand alot about it, yet more or less pointed out what I cannot comprehend!
VM, the human race knows nothing of any real value about the mechanics of time travel, why are you assuming that it would require vast amounts of power? Maybe it is something simple.
Because your talking about literally bending spacetime back on itself. A wormhole is essentially a black hole that has a beginning and end that don't involve gravity. Take a piece of paper, and fold it in half. Now put a hole through both halves. THat's what a wormhole does. The calculations have been done on it, and it is astronomical the resources needed for it. Read The Fabric of the Cosmos, it has a whole explanation on this :P
Saw this on his site a while ago, and really liked its explanation of these concepts. However, I have always had a problem with the whole "time travel" concept because, what if you were to go back in time, and give yourself a locket or some object. Then, that you lives his life until he goes back in time and gives it to himself again.
Where did the locket come from? It is essentially creating something from nothing. It works the same way with information. If you went back in time and told yourself how to build a perfect computer or something, who invented it?
The only way time travel would work is if you were to splinter off into a symmetrical parallel universe.
Actually Mudra it is considered possible to go back in time by jumping through a wormhole. It is speculated that you can reach the speed of light by doing so, and if you manage to survive, surpassing the speed of light will send you so fast forward in time, you'll end up behind where you are about to be, thus, back in time.
