Brent,
You seem to be saying 1. that the matter that enters a black hole through the event
horizon warps space as it enters and 2. that then that space warp persists as the matter
disappears into the singularity.
1. is of course correct but 2. isn't. Consider a mass traveling through empty space. As
it travels it obviously does warp the space around it but as soon as it moves away that
warping dissolves. The warping is carried along by the mass and exists only around a
mass. So by your thinking the warping should persist all along the path of any traveling
mass but it doesn't. The earth and sun don't leave permanent trails of space warping
behind them as they move through space. The warping travels WITH the moving mass and is
maintained only by the continuing presence of the mass.
So there can be no warping left around a black hole if the matter falling into it
actually were to disappear. The warping is maintained ONLY by the continuing presence of
mass, just like it is around a mass traveling through empty space.
Do you understand my point here?
Yes, I understand you're still trying to use your Newtonian intuition of predict what a BH
does. Just look up the derivation of the Schwarzschild metric and explain what it means
that T_u_v=0.
