When Einstein proved the Theory of Relativity, he also proved the connection between space and time. For example, an atomic clock travelling at high speed in a jet ticks slightly more slowly than its counterpart on the ground. The difference is extremely small when we're dealing with jets and cars and such, but at velocities approaching the speed of light, the effect is enormous. So in fact, we use time machines everyday. At least to move forward in time.
I don't know too much about how it works, but I have been explained that if we ever will be able to use wormwholes (also proved by Einsteins theory of relativity), we would also be able to travel back in time

OK, I admit my English is not as good as it should be (and that my knowledge of Einsteins theories lacks a little, I must admit), so my last reply may have come out wrong.
But apart from that, it has been proved that time moves slower on moving objects (this has been done scientificly by placing an atomic clock on a Boeing 747, while another was placed on the ground). By comparing the two clocks after the flight, it showed that time had moved slower on the plane.
The theory of going back in time, goes something like this (once again, excuse my poor english):
If you could open up a wormehole, and place one end on Earth and the other at a spaceship going close to the speed of light, you could go through the wormhole from Earth to the spaceship, a place that was back in time compared to time on Earth. Don't hold me to this, but I'm sure that is how it was explained. You could of cours not go further back than the existens of the wormhole.
Anyway, timetraveling is mathematicly pheseable, but will remain a theory until proven wrong.
Hope that came out right

Well, your "matrix"-approach to this question might satisfy your perception of the world, but have nothing to do with the real world physics. The gravity pull of any object actually bends space, the larger the object (or densier the mass), the bigger the gravity pull. Just check this out with your fellow country man, Stephen Hawking (one of the greatest geniouses today who has explained the existence of black holes). I'm sure he will answer any questions you might have regarding space and worm holes

Hi again V-Bird,
You wrote: "Time travel cannot be mathematically feasible because we have no mathematics for time!"
We do actually have mathematics for time. Time is often considered to be the fourth dimension. You can read more about how to incorporate time into your everyday mathematics here: http://www.jimloy.com/physics/4d.htm

I enjoy this conversation, but I think it's time to hit the sack. It's getting late here in Norway, and I could probably go on all night discussing this topic. Anyway, I would advise you to read up on the latest progress in String Theory at http://tena4.vub.ac.be/beyondstringtheory/main.html
Once you get the grasp of that, you will surely understand more about the physics of what you are trying to explain to me...
Good night
And Crashfrog, thanks for the support

OK. I'm sorry, just had to throw this in here before I went to bed. I posted the wrong link earlier. Just wanted to give an insight of the String Theory, and especially the M-Theory "theory of everything", which will probably solve the time travel dilema. This was the link I should have posted:
Error 404...
