No, the black hole cannot effect the
outside world.

Whaaa...? A star collapsed to a BH still holds is planets in exactly the
same orbits as before the collapse. Clearly, it expresses gravity to the
'outside world' exactly as before.

Only the event horizon can. But, if the
event horizon vibrated... it might create such waves.
Most likely though it is the trace of things just as they are entering
through the
event horizon.

This bears on the "speed of gravity" question and the popular belief
that gravity propagates at, and is limited to, the speed of light. If
that were the case, gravity would not be able to reach outside the event
horizon. Clearly that is not the case, proving the 'speed of gravity'
far, far exceeds the speed of light.

BTW, where is Mr. Webster Smogpule? He hasn't ''weighed in" lately.
