Forever time dilation!?!

[paultrr]

One question that would have to be answered is how one gets to that speed without hitting C? However, assuming one could, say in some type of quatum jump, you'd be in the way you've discribed such a case going backwards in time. Another words, you'd be in a tachyon state. Problem is in the real world things do not work like that. While quantum tunneling is possible for say particles and even in a few recorded cases with EM fields the distances over which such take place are far to short to say push a macro size body through that way. So quantum tunneling being out rather elimnates any way for what you are thinking about to be possible.

Time is a measurement. We measure by the ticking of a clock. It ticks, we have

traveled in along the time coordinate of one tick. Tick Tock Tick Tock... See.

Time Travel. Now for dilation. Same person, same clock on a rocket moving at

10% the speed of C in a straight direction. Same person same clock sees passage

of time the same. Different observor at rest with respect to rocket observes the

person's clock in the rocket is moving slower than his clock. This person at rest

considers the person in the rocket has his time "dilated". Relativity has the same

effect for the person in the rocket. The person in the rocket see the person at

rest to him has his clock moving slower. He views his time is dilated.

 

I do hope this clears it up... :Alien: :Alien:

I understand that it is useless to compare two different reference frames, but why is it that until a person traveling at a sufficient fraction of c returns to Earthly speeds he is equally right in saying that he went faster as Earthlings are in saying that they had? It reminds me of the cat - it is NOT both dead and alive, it is either or. Just because we don't KNOW which it is doesn't change anything. Why can't we tell who was traveling faster?

 

Also, it is known that the faster you one travels, the slower they age. So if the traveler were to somehow see an Earthling and vs., which would perceive the other as older? It obviosuly cannot be both because no matter how much you twist words around, if one stays on Earth and the other travels at nearly c, they are NOT the same age. Then couldn't we also tell which is traveling faster?

 

And in general, why does this symmetry exits? Why does each think the other is moving slower?
