Brent,
That's just your interpretation and you apparently ARE UNABLE to find any authoritative
sites to confirm it. Yes, of course the mass interior to a BH collapses into the
singularity but that doesn't mean it vanishes from the black hole.
Looking at Carroll's Wiki Bio it seems that a lot of his theories are highly speculative
and unconfirmed...
Here, on the other hand, is a quote from Kip Thorne's 'Black Holes and Time Warps' which
says otherwise:
"The hole must be born when a star implodes upon itself; THE HOLE'S MASS, AT BIRTH MUST
BE THE SAME AS THE STAR'S; AND EACH TIME SOMETHING FALLS INTO THE HOLE, ITS MASS MUST GROW"
So what? Your question was about how does the gravity get out if the mass is inside the
BH. But the point is that when matter falls into the BH the mass of the BH increases but
there is still no matter inside. The matter is crushed into a singularity (in the
classical approximation of course) and what remains is a VACUUM solution to Einstein's
equations known as the Schwarzschild metric. The increased mass just went into warping
more spacetime. Notice that when Thorne describes and astronaut falling into a BH the
astronaut never encounters anything inside the BH except the singularity. And he assumes
the biggest know BH so that the astronaut reaches the singularity only 20hrs after
crossing the event horizon. So ANYTHING inside the BH will reach the singularity in 20hrs
or less. That's why a vacuum solution is a good model.
