amantine - right, we use relativity to compare observers in different reference frames. It's kinda of interesting that if I see a car drive by me,
without the reference of the earth I wouldn't be able to tell if it was me or the car that was moving. In fact, either or both could be right (maybe
we're moving towards each other!).
You did answer one of my questions - the rate through time could be considered time per proper time - it's dimensionless, which I guess makes
The absolutes I'm talking about would be when you compare any reference frame to one that is fixed in space. If the universe is finite, then such a
reference could be determined. If the universe is infinite, however, then there really wouldn't be a truly stationary pont, at least, not that we
So this brings up an interesting question - when we talk about the age of the universe, what reference frame are we in?
