ok , lets say . . i move with the speed of light . . how do you prove that my body age less ???. . the metabolic rates will be the same ??will it ???. you dont age WRT time .cause time is just an imaginary thing or a reference . and i dont think its got any connection with ageing . cause cells in any organisms body dont work with relation to time . but with relation to environment thats around it . . am i right ???:-l
Wrong, when you travel with the speed of light or even close to it, your bodu ages less. Everything in this space is time .Remember that. That is what Einstein's General Theory says and that is what has been proven too. This happens becuse of what happens inside the atoms themselves. Even subatomic particles stop aging.
Please see Halliday and Resnick, somewhere in the last chapters. He cites an experiment where a subatomic particle is moved 99.98% speed of c or so and the particle which is supposed to decay in 2 microseconds decays in 63.5 microsecs(mayb i screwed up the numbers, doesnt matter).
The explanation is:
In the time frame of the particle ,it has lived for 2 microseconds only, but in our time frame, it is some 60-odd microseconds.
Same way, when you travel at such high speeds, your body thinks it is just an hour or so, but infact ,you've been spending a lot of time.
And what do you think the Twin Paradox is all about?
