TTT, scientists hypothesize that time travel is possible. Through the use of worm holes, but there is a major problem worms holes are about a few nanometers across and only last for a few split seconds.
Here is a thread to discuss time travel and pose hypothetical questions.
Please don't cite wikipedia... because people like me edit it too..
If you really want to read about realitivity and Time travel, pick up Steven Hawking's book: The Universe in a Nutshell
I may be missing something... Could someone please explain what evidence exists to support this wormhole theory? Sounds more like Science Fiction to me.
Well, I was just using that as an example. What if someone killed Noah while he was building the ark. I highly doubt that God would let that happen. Which is why I don't think time travel could ever exist.
Will we please agree to stop posting about God? This is a very interesting Physics scenario and I would like to let the science flow without restriction. If anyone wants to debate about God, go to one of the numerous threads about religion.
Wormholes are a very nifty subject. The sheet of paper that you mentioned DDX I believe is Space-Time? As I hear it, it is theorized that gravity has the effect of creating dents in that sheet. More gravity equals deeper dents. I guess if you get enough gravity in one location you can create a dent that goes all the way to the other side of the universe, this idea of wormholes. Supposedly a blackhole which appears to suck things in without end has this ability. It's an interesting theory and one that I might look into further.
Also in regard to the wormholes you mentioned that are very small. Did know as you approach the speed of light you appear to lose dimension to onlookers? That is you appear to become flatter, maybe there is a correlation?

First off I would like to thank you for being the first serious poster.
Anyway, the theory of relativity proposed by Einstein did say that, however if wormholes were bigger don't you think we would have found more? hmmmm.

Not necessarily, see my thought is that perhaps blackholes produce larger wormholes because of their vast amounts of gravity and seeing as how the only thing that appears to escape blackholes are x-rays, we don't really have a clue as to what's inside of them.

This part, what I figured was perhaps as a person approaches the speed of light maybe these smaller wormholes would become larger and maybe accessible. Not to mention at these high speeds even if they only last a split second, you'd be through them before they dissipated.
I actually have never come across the notion of somebody raising a theological objection to the concept of time travel before this. Perhaps the matter could be brought up in a separate thread.

Would this be related to the basic spatial effects of special relativity? In this case it wouldn't be so much "flatter" so much as "longer". Or is this something separate?

I think it has to do with e=mC^2 cuz of Einstein and all.
I'm not sure exactly but as you go faster you're supposed to become more massive too. Umm, It's been a while but I'm sure this somehow correlates to how you do become "flatter". It's been so long since I had a good conversation on this subject.
Oh wait I remember now you become *less* massive as you approach the speed of light. Then to maintain density your volume must also decrease, therefor you become flatter
Alright, yes, I believe you are talking about the basic (experimentally verified) phenomena, which is that as one approaches c, one becomes longer and more massive in a manner proportional to the expression 1/(c^2-v^2)^(1/2)...please pardon the horrible syntax!
A more comprehensive explanation of spatial and kinetic effects in special relativity exists in Wikipedia, though it's also been a while since I've looked at it properly too!
But the bottom line is that I doubt that one would literally become "flatter"...I think the spatial change is only in the dimension of the direction of motion.
Oh wait I remember now you become *less* massive as you approach the speed of light.
Woah, wait up, that's completely the opposite of the theory!
The rationale for it being (according to Newtonian methods, that is) impossible to actually achieve c is because one becomes more massive (see above formula), such that in order to reach the speed of light, one would have to expend infinite energy even in an ideal system, which is impossible.
... Waaiiiit just a moment. Perhaps I was thinking of the other direction?
As you slow down you must become less massive and therefor lose dimension. I think this thought popped into my head a while back when I was talking with my father about 2 dimensional existance.
I'm more used to framing this kind of discussion in terms of FTL travel (faster-than-light travel), in which wormholes are one possible (some would say fanciful, depending on if you're Stephen Hawking or not) idea. Others include the Alcubierre drive (otherwise known as quantum tunneling...I think)...and at that point my memory gets hazy!
Anyhoo it really is a shame when this kind of cool knowledge is forgotten. I'm in college right now for engineering so I'm more into the applied side of science than the theoretical type.
Oh well.
On the topic of wormholes, I'm not sure if I believe its possible to perform time travel (I'm not even sure of what I know >.>, but I do have a rather involved concept behind it and other things. If anyone is interested in the various dimensions theorized to exist you should check out String Theory.
