Well the imbalance in the gr will be in all directions.
GR does not argue with space time.
Space time it still seems to me says neither gravity attracts or that it "pushes" ..the approach is an observation of relationships between objects and space.
Singularity is finally the pointy end of the space time expression.. it is produced when the numbers become extreme... the mass of a black hole distorts everything to a singularity.. on paper.
Personaly I wonder if they can exist in the real Universe.
Maybe matter can not exist in such a way to form a black hole.
Maybe the concentration required is never reached... because of a rule we no nothing about preventing mass concentration past a point.
I feel uncomfortable that we can only ever infer their existence by "wobbles" and long range "observation" I would like to see a truck load of it ...mmm maybe not it would be the ultimate shield ..so you would be pushed to death upon it.
We after all admit that conditions will be so different to what we know inside a black hole that current science may well be meaningless.
Perhaps "nature" will not allow the concentration of mass required to form a black hole.. the theory predicts one if the numbers are right..maybe the numbers can not be right in so far as matter simply will not accumulate as required.
The possibility of GR being in the mix suggests alternatives but it can follow the space time math where ever it goes I guess.
If this be the case (matter is prevented from accumulation past a point) we have no singularity in the real Universe and that sounds simple but that is what the razor dictates.
So much comes from getting a little bit of data and extrapolating extremes.. expansion of the Universe..its one thing to note an expansion and another to infer it started at a point I feel.
A black hole comes from the possibility of concentration of mass and the effect of gravity (a force no one has any ideas on..current company excluded) at the extreme end of the extrapolation...
I just wonder why black holes.. they sortta dont fit in.. not even as a central hub of a galaxy.. their relative mass has little bearing on holding stuff in place..dark energy does that.. so what is their purpose... other than to satisfy the extrapolation of the geometry. Are they gobbling up their galaxies to reach singularity?? and join the other singularities to form the ultimate singularity???
Still that is just my thinking aloud..sorry.
Well Ron it has been a great game.. we must play again some time.
I compliment you on a fine victory
