Fascinating new theory about time, as NOT the fourth dimension:

&#1... Reading the article again, it exactly restates what I said earlier: Time as a "thing" does not exist.

> Einstein models (note the use of the word 'model') time by assuming that time and space are equivalent. Time thus becomes the interval of some object as it travels some distance on a map. Time as a *real thing* does not exist for science. Without motion, there is no time.

> Merging in with what dhw had said about time previously, Einstein's view was that time was "only a sequential ordering of events."-And now Gravity Probe B has again shown that space is warped by a big body, here the Earth, and space is swirled or stirred a bit by the planet's rotation and orbit.-The space-time concept is useful, even if time does not exist except as a human concept:-
