Is the acceleration of the gravitational pull of the black hole different from one black hole to another?
I know that the gravitational pull is greater than the speed of light. But can this be measured and compared from one black hole to another? Also, are there any direct correlations of this property to the acceleration of the expanding universe?

The acceleration due to gravity of a black hole depends on the mass of the black hole. Each black hole has its own mass, and this determines the strength of gravity at a given distance. It is a bit inaccurate to say that "the gravitational pull is greater than the speed of light." It is better to say that the escape velocity is greater than the speed of light, within a certain radius called the event horizon.

The only difference there would be from one black hole to another is the strength of its gravitational field. This would depend on how massive a star had collapsed to create it, and how much additional matter had fallen into it. The acceleration of the expansion of the universe is not completely understood at this time but hypothesis are leaning toward it have to do with the dark matter and or dark energy that exists in our universe.

The above is 0.5 suited. The acceleration (no longer probable pull) of gravity is with regard to the completed mass of the object (no longer purely the density) and the gap from it. a much bigger mass has extra acceleration at a given distance or the comparable acceleration at a much bigger distance. the form horizon is the ingredient at which the acceleration of gravity is sufficient to make get away speed extra desirable than 186,000 miles according to 2nd. A extra huge black hollow might have a much bigger diameter experience horizon. In theory, the black hollow itself is an infinitely small and dense ingredient interior the middle of the form horizon. you could form of think of of the form horizon because of the fact the floor of the black hollow and the mass because of the fact the load of the black hollow, yet no longer precisely.

It the black holes have different total masses, then there will be differences in their gravity based on your distance from the event horizon (the point where light does not escape) At the event horizon, the gravity is the same because the escape velocity from the gravity field is equal to the speed of light. But the event horizons of two black holes of different masses will be different sizes.
As you move farther away from the two black holes, the gravity of the more massive one will be stronger than the less massive one.

The more massive black holes have more gravitational tug so the event horizon (point of no return) will be larger for the more massive one. Also outside the event horizon, for the same distance from each, the acceleration due to gravity will be higher for the larger one.

Black wholes are large masses of matter that is all. if you where to compress earth it would fit into a table spoon. and that table spoon would be a black whole. the gravital pull would equal the same as earths gravital pull compressed or not. so the graviational pull for a black whole is defferant depending on the masses with in the black whole. All of them are defferent.
hope this helps

Black holes can veiry in gravitaional pull bueing to their size
