No, at least according to Einstein's special theory of relativity. Maybe the Book of Mormon says different, but this is what I believe in. Read my post and/or something about that theory to understand.
Edit: Specifically read this: http://en.wikipedia.org/wiki/Velocity-addition_formula

pete's just saying don't confuse science and theology, which is something that's often hard to due to for a person with strong religous beliefs.
like pete said, your theory was once accepted, but since science has bypassed the first set of newtonian physics and agreed that it's incorrect, it's widely agreed upon to be incorrect.

my problem with this, is that even though the clock isnt "ticking" according to him, TIME for him is still ticking, time runs whether the clock is or not. just becuase light rays portraying the time on a clock doesnt "Reach" a blind person's eyes doesnt mean the clock isnt ticking, or that the time the clock is telling isnt still going forward. maybe to his sense of sight time has stopped, but that doesnt mean he wont age while sitting in that train. I personally am extremely interested in all this bullshit, and i cant figure out any sort of way it could be possible at ALL, like not even because it would fuck shit up. but think about this:
LETS say, someone figures out some sort of way to travel into their past, wheres the huge harddrive storing everything that has happened to them? surely we can travel back in time with like remembering things, but where is that actual instant stored? There's information stored in our brain that makes it possible for humans to think about something that has already happen, and basically relive it if they really are that bored and concentrate. Problem is, where is that information stored that would be available to a device that would transport you to that moment? thats sort of what makes it seem impossible to me.
just to take this idea 1 step further,
-lets assume there is a massive harddrive somewhere, recording every moment of everything happening everywhere.
-a man goes back in "time" (clicks on the "past" folder in windows explorer) and decides to open up "conception.txt" and delete the part where his parents get it on and concieve him.
-logically, this would at the very least postpone his birth.
-SooOoOoO where is the program that runs through every *.txt, figures out what WOULD happen now that they didnt have sex that night and changes it in the file?
-furthermore, where is the insanely powerful cpu that powers that program?
HA, better get on that one, microsoft
same would apply to traveling forward in time. which seems even less possible to me. to travel in time, there would have to be events that have happened to travel to. and obviously, the future hasnt already happened, so either the "time machine" sort of makes up what happens, or it cant do shit because what WILL happen cant be set in stone or stored as something definite

damn bk just owned chase
and the only effective way that i think there is to travel into the future is if you want to go 5 minutes into the future then you have to wait 5 minutes. and going into the past would only mess everything up if it worked. because it could result in you never builind a time machine. so you would like disapear or something

This is the matrix conception, haha. Well, your conception in the future is kind of wrong to me. The future exists, it's only the unaccessible part of the spacetime that hasn't even happened yet. The fourth dimension, time has one direction and the space is 'moving' along it. The flow of time is our personal illusion, based on the facts we remember about the past in appropriate order, the way we concept world etc. Imagine that your brain has no, or very little memory, you would hardly be able to concept some of the present, and the past would seem as shady for you as the future is (maybe it's the case of some primitive animals). I guess that if you drug your brain the time might feel like going fast or slow (maybe the same thing happens when you're having a very boring lesson at school, or find yourself playing an awesome game in the evening and suddenly realize it's 4AM). I guess that the time flow rate varies for different living beings, maybe for different people also.
The main thing is that I'm a determinist when it comes to thinking about the world. If we scanned the present universe, as in every particle, wave with it's physical data, then put it into a computer and applied an algorithm of a perfect set of physics laws, we would get a perfect universe simulation. This includes such complex systems like gas particles or human brains generating thoughts etc. I believe that nothing is random, even though some argue that the quantum inequality (I guess that's the law that says that we're never going to 100% locate an electron in the atom or something like that, I horribly suck at quantum physics) is what generates the random events, there's even one book that argues that this is tha way God influences the world. This is a weak argument for me though, and I believe that with this kind of perfect simulation we would be either able to 'reverse' time and go all the way to the big bang, or accelerate and see the future.
As for time travel, Brandon has spotted an important issue of targeting the point in the spacetime where we would like to move. Some time machine stories Ive read tell about machines 'that move you in time but not in space' which results in dropping the guy in the middle of the forest 100 years ago, because the time machine workshop didn't exist back then, or splitting a person in half after being teleported in the middle of a wall or something. But then, you can argue that if you move half a year back, the earth will be halfway around its orbit so if you move back in time in the same exact spot, you will end up in space. But then the solar system moves... etc. The modern physics says that you can't figure out a fixed point in the middle of the universe to refer everything's location to, that's why it is so hard to concept, for me at least.
Superman did it.
But yeah, all stuff about space and time and worm holes and black holes and teleportation and stuff is confusing but very interesting.
i love trying to understand it.
A wormhole could allow time travel.[8] This could be accomplished by accelerating one end of the wormhole to a high velocity relative to the other, and then sometime later bringing it back; relativistic time dilation would result in the accelerated wormhole mouth aging less than the stationary one as seen by an external observer, similar to what is seen in the twin paradox. However, time connects differently through the wormhole than outside it, so that synchronized clocks at each mouth will remain synchronized to someone traveling through the wormhole itself, no matter how the mouths move around. This means that anything which entered the accelerated wormhole mouth would exit the stationary one at a point in time prior to its entry. For example, if clocks at both mouths both showed the date as 2000 before one mouth was accelerated, and after being taken on a trip at relativistic velocities the accelerated mouth was brought back to the same region as the stationary mouth with the accelerated mouth's clock reading 2005 while the stationary mouth's clock read 2010, then a traveler who entered the accelerated mouth at this moment would exit the stationary mouth when its clock also read 2005, in the same region but now five years in the past. Such a configuration of wormholes would allow for a particle's world line to form a closed loop in spacetime, known as a closed timelike curve.
It is thought that it may not be possible to convert a wormhole into a time machine in this manner: some analyses using the semiclassical approach to incorporating quantum effects into general relativity indicate that a feedback loop of virtual particles would circulate through the wormhole with ever-increasing intensity, destroying it before any information could be passed through it, in keeping with the chronology protection conjecture. This has been called into question by the suggestion that radiation would disperse after traveling through the wormhole, therefore preventing infinite accumulation. The debate on this matter is described by Kip S. Thorne in the book Black Holes and Time Warps. There is also the Roman ring, which is a configuration of more than one wormhole. This ring seems to allow a closed time loop with stable wormholes when analyzed using semiclassical gravity, although without a full theory of quantum gravity it is uncertain whether the semiclassical approach is reliable in this case.
