Brent,
Please at least keep the record straight instead of making snide comments about
me.
I asked How does mass inside a BH produce an gravitational effect outside the event
horizon if gravity propagates at the speed of light and nothing can go faster than the
speed of light to come out of a black hole?
Your answer was that when mass enters a black hole the mass disappears completely into
the singularity and has NO gravitational effect outside and that the gravitational
effect of a BH is somehow left over space warping from the passage of the mass before it
enters the BH which seems like a pretty crazy idea. Passing mass doesn't leave trails of
its space warping behind in any other circumstances.
But it's not "passing" it's being crushed into the singularity.
My answer, that no one including you got, is that it is the gravitational field of the
mass inside the BH that creates the event horizon in the first place so gravitational
effect of the mass inside the BH is already 'out' by the time the event horizon is
created and there is no problem emerging from the event horizon since the gravitational
field is what creates it in the first place.
Which I also pointed is why a planet orbiting a star which then collapsed into a BH would
not experience any gravitational difference at its orbit. Jesse also gave a similar
explanation noting that the field at any point can only depend on things inside its past
light cone which means that the field at any point outside the event horizon can only
depend stuff outside the event horizon.
So don't try to change history by snidely implying I got it wrong and you got it right
when the opposite is true....
You claim that BH's don't even have any mass and the curved space outside the event
horizon is residual warping with nothing to sustain it which is incorrect. i provide the
obvious answer of how the actual mass inside a black hole produces and sustains the
actual gravitational field outside the event horizon.
It's not just me. Look up the Schwarzchild metric anywhere. You'll see that the matter
term is zero.
