Why black holes cannot have singularity or infinite gravity?
Black holes are called black as no light may escapes the gravitational pull. This is expected as in general relativity the gravitational
pull is mediated by gravitons. Just like photons the gravitons have no rest mass. Gravitons interact with space as well as matter. If
massive gravity can stop the escape of light in a black hole then why there is not a similar effect on the gravitons. This however will cause
abrupt disconnect of black holes gravity from rest of the universe as the gravitons mediating the gravity should not escape massive gravity
of the black holes. Observations however do not support this picture.
Astronomers know of objects in the universe which fit the black holes model but these objects are observed because of the massive
gravitational pull they exert on the surrounding objects.
Now let us consider that gravity is time differential generated by the expansion of space. Near the center of a very massive object
time will be slower as expansion is slow. In even more massive objects expansion can be brought to “almost complete halt causing time to
approach zero. As expansion of space generates forces and allows motion and time therefore with no expansion there is no further
increase in the gravitational force. Gravity can operate only between near zero expansion and higher expansion of space that is between
near zero time and a faster time.
There cannot be infinite gravity as the driving factor behind every force or motion is the expansion of space. This is why so called
super massive black holes do not disconnect and disappear from the universe as one would expect in infinite gravity. Black holes can be
larger or smaller in diameter but the gravitational pull of the black hole has a limit beyond which gravity cannot increase.
