you just don't get it. here is an experiment that humans actually participated in...<quoted text>
Time is not slowed or sped up for GPS or satellites. Now it does take just a little time for their information to get here for it is not instantaneous, but time is not either slowed or sped up,,, we call it time to update and get caught up
if have two watches and you put one on satellite and keep one on the Earth, they will not register the same amount of time. the warping of space time caused by the gravity well of the Earth makes time different here than up there.(as SZ pointed out, there is also the speed of the satellite to take into account...)
time is different in different kinds of space because space and time are one.
seriously, you really need to research this so you don't look like such a rube...
