Quote miketaurus="miketaurus"Erm ... Forgive my underdevelopment in this theoretical analysis but as we cannot travel at said light speed, we dont know what is at the end of it .. as far as travelling. Do we?
Fascinating though ....'"
Course we do. Old Einstein figured it all out, and every single test has only confirmed the old boy's theory. We perfectly understand how time slows with increase in speed, and while we cannot (yet) travel at light speed, communications to fast moving GPS satellites can - and do; the clocks on the GPS satellites do not run at Earth rate, but run slower than clocks on Earth. Because relative to clocks on the ground, they are travelling much faster.
The amount by which they run slower is calculated by the theory of relativity. What you need to do is calculate how much their extra speed will slow down their local time; then set their clocks to run that bit faster than "normal". Until it appears, viewed from Earth, that their clocks are ticking at the same rate as our clocks.
If they didn't do this, GPS wouldn't work properly. Granted, as in relative terms, the increase in speed is tiny, the time dilation is minuscule - but is real, is as predicted, and you prove the fact of time dilation each time you use your SatNav.
When Omari Caro sprinted down the field, as a result of that run, he is an infinitesimal (but precisely calculable) amount of time younger, relative to the spectators, than he would have been had he not made that run.
