    I looked up the definition of a Gravitational Singularity and it defines it as a gravitational pull that is infinitely strong.

    This is how it's represented in physics and mathematics. But in reality, there is a limit on how strong that attraction is right?

    The singularities are predicted in General Relativity. They represent the point where General Relativity is no longer useful as an accurate description. GR does not describe Quantum effects. That is not a problem until your talking about a mass being compressed to a size where it can no longer be ignored. Essentially it is where current accepted understanding ends.

    So the answer to your question is that it most certainly is not infinite, but nobody as yet can say anything else without speculating.

    Would we be able to make a simple statement that the gravitational pull of a black hole of a 100 solar masses is greater than the attraction of a black hole with 50 solar masses without speculation?

    Yes. Away from the event horizon, and even a little inside of that, current understand works just fine, and a more massive black hole has a stronger gravitational pull. We just don't know what happens as you approach the center where GR says the pull would become infinite. (Infinities are generally a sign that something's not working right.)

    Grvitation is infinite in 2 dimention , to get free from it , what you get is 3 dimention of space . Thanks

    There a rison why you free 3 dimention to space and not 1 , 2 or 4 and it conect to time , you probely joke from it so meen while i keep it to my self

    If you move partical 3 time in time back and forth you can multiply the space by 3 , but why 3 time , that il keep to my self , and that two the rison way the forth have 2 degre .

    I have never seen him post anything that is readable. The worrying part is he spent half an hour crafting those three posts.

    Infinities are always difficult for armchair science buffs like us to try to comprehend. In the case of the singularity at the center of a black hole, I find it easier to understand if I describe it to myself as "the gravitational force asymptotically approaches infinity as the radius asymptotically approaches zero". This way of thinking may not be strictly scientific, but it allows me to think of a gravitational field that never quite becomes "infinitely strong" (or infinitely weak, for that matter).

    It would look something like this:


    If you consider the "x" axis to be the radius, the "y" axis would be the "strength" of gravity and the red line in the upper right hand quadrant would show the relationship.

    Look up big word to see what means it.

    Check my previous post again - I added a graph to show the relationship.

    Please reword the underlined portion - I don't understand what you're trying to say.
