How about this two clocks the same types set to the very same time
in ten's of seconds:
One is kept on the ground and the other is put in a very fast jet plane
flying 60,000 ft.
12 hours later you check both clocks: tell me are both clocks still the same
time or different times in ten's of seconds?
Thank you for continuing this discussion.....I got your point of time dilation....that is a true and absolute proven point, I know there will be a difference but lets take it further....a plane circling the earth near the speed of light and according to Einstein that would be considered time travel into the future because of the time difference mulitiplied by speed and all effected by gravity but the plane has the whole time been traveling
with Earth through space and only offers a trip into the future with no return to your original point of time. See because the plane stayed with the planet, this experiment might be considered a type of time travel it is what I would consider a relativity experiment because the plane was controlled to stay relative to the planet but time was experience on both objects. I agree with you and it maybe able to "time cloak" yourself and appear in the future relative to your own time experience but I think that is like being froze and woke up later....see what I am getting at? I think that your right and time travel in this fashion maybe possible and wins that debate of time travel is possible on Earth but also may prove there is only one way to travel ....forward in time....let's call it Einstein's amber or time cloak.....lets keep going and shooting ideas....you think it is possible to travel back and forth through time?...I always wondered something else ....if it was possible to travel then I wonder how the universe could handle the loss of mass (or energy) from you leaving this time frame and appearing in another (there would be an increase once you entered the new time frame...except time cloaking because you were always here but moving through time at a different rate).....let me hear from you
