Brent,
We have to be careful to be precisely accurate here.
1. The structure of a black hole is not just a singularity inside an event horizon. The
entire interior of a black hole is not a singularity. The singularity exists only at the
very center of a black hole, there is plenty of volume between the event horizon and the
singularity.
Actually there is plenty of *time* between the horizon and the singularity - if the black
hole is large enough. The singularity isn't at a different place, it's in the future,
once you're inside the event horizon.
2. We have to clearly distinguish gravity WAVES from gravity itself. Gravity waves are
NOT gravity, they are small fluctuations in gravity.
Of course they are small warps in space. But warps in space *are* gravity.
So yes, gravity WAVES can radiate away, but the gravitational force itself remains
unless the mass that produces it vanishes.
If, as you propose, mass vanishes inside a black hole (no one else believes this BTW)
black holes would produce NO gravitational effect....
Of course matter doesn't vanish just because it crosses the event horizon. But so far as
the classical theory goes it vanishes at the singularity. It takes some time to get to
the singularity, but it's relatively short for a black hole that forms from a star.
But even though the mass vanishes the black remains and warps space around it. Which
everybody who ever solved Einsteins equations for the Schwarzschild solution knows. It's
a *vacuum* solution. There's no matter in it. It is because Einsteins equations are
non-linear gravity acts on itself and so can act as it's own source of gravity.
