Brent Poor choice of a word on my part; he didn't "show" gravity wasn't a force; rather he concluded it from a thought experient of man in free fall. You can conclude this from his direct quote, which I recently read. AG In any event, I don't think there is any direct relation between the EP and the GR field equations. What apparently happened is that Einstein's conclusion that gravity isn't a force, forced him to look elsewhere for a new theory of gravity. That elsewhere turned out to be the geometry of spacetime.

Alternatively, how are the field equations implied by the EP? TY, AG -- You received this message because you are subscribed to the Google Groups "Everything List" group.
