Sorry for some probably very basic questions, but here goes.(adsbygoogle = window.adsbygoogle || []).push({});

If gravity equals acceleration, how is the Earth's gravity defined by acceleration?

If an accelerating body distorts spacetime, as described in Einstein's thought experiment about a light beam shined through an accelerating box, how is this equivalent to gravity in terms of what's going on outside the box? Put another way, is an accelerating object's equivalence to gravity only extremely local to the object?

If a large body's distortion of spacetime is propagated by gravitons, as some have theorized, do accelerating bodies also produce gravitons? Einstein's thought experiment suggests to me that the answer is no, because the spacetime distortion seems to be a function of geometry, not force. But then, whence gravitons?

--Thanks for indulging a non-physicist (but a curious one!)
