"affect" space-time outside the event horizon?
by what mechanism?
another way to ask:
does mass warp space directly?
so is what we see as "gravity" is just the warping of space?
Or does mass give off a gravitational field
consisting of "gravitons" which interacts with
other bodies and space.]
Of course mass warps the spacetime around it. That is a core feature of GR. The two are only different perspectives.
