David,
> > Einstein's spacetime is a mathematical construct that eliminated time as a fourth dimension and simply treats time and space as the same quantity. Time is relative--that's the whole point of the theory of relativity. If time were a real dimension, it would be the same for all bodies of mass everywhere, but for massive bodies, they experience time at a slower rate than small bodies.

> And faster bodies become smaller. And speed slows the machines we construct to tell time. Makes more sense to me than it did before. But what of the proposal that a twin who travels near the speed of light returns to Earth much younger than his brother. If time is just a human construct how does it affect biological processes of aging, or does it?-It doesn't; Physics rejects any notion of a single frame of reference for time. That means exactly this: Time for me is different than time for you--if we're on differing masses. If I was on a ship going the speed of light (which requires A LOT of mass) my time would slow in relation to your time, but not against some universal law or physical reality. Biology works just the same for me as it does for you, I will feel it at the same rate as you, but yes, I would come back younger than my brother. -This is one of those counterintuitive results that physics is famous for.
