Obviously, Albert Einstein is sticking is tongue out at all the haters and doubters out there!
His General Theory of Relativity predicted that super-massive, incredibly dense objects, such as the core of a black hole, could create such deformation of the time-space continuum that the gravity created by these objects could be virtually infinite.
The further away from a super-massive black hole (SMBH) you are, the less you are affected by its gravity. However, if you venture too close and become entrained in its gravitational vortex you will begin to accelerate until your speed exceeds that of the speed of light, meaning that no one further away from the SMBH than you are will be able to see you! Eventually, your mass will unite with the mass at the core of the SMBH, but in a quantum state in which all that exists are the smallest of sub-atomic particles, all packed into a infinitesimally tiny space (at least, relative to the mass). I don't believe that anyone knows the diameter of the core of a SMBH, or exactly what state of matter exists there, but I would predict that the extreme forces and energy involved (keep in mind a SMBH eats suns for lunch) would break down atoms way beyond electrons, protons and neutrons to subatomic particles that we've never detected and whose behaviour we can only imagine. I also predict that, in the SMHB core, the subatomic particles are as tiny as they can possibly be, are all the same and are arranged in a matrix or geometric pattern, very much like a crystal.
Eventually, all matter in the universe will be reduced in this manner until the black holes themselves begin to be drawn toward one another. Since the sub-atomic particles in the core of the SMBH want to repel one another, bringing two SMBH of similar mass into proximity to one another could destabilize one or the other core which I predict would result in a massive explosion, similar to the "Big Bang". This explosion could propagate throughout the universe, destroying all black holes and creating a great cloud of sub-atomic particles which will begin to arrange themselves to form the building blocks of all matter that we now know.
Getting back to my original point, Einstein's General Theory predicts that the force of gravity at the center of a SMBH is infinite, basically because the force is 1/r, and when r = 0, the result is mathematical infinity. However, it is a force we are talking about here, not some equation on a blackboard. Force is mass times acceleration (F = ma), and so when r = 0, a = 0 and F = 0. Therefore, the gravitational force of a SMBH is a limit approaching infinity, but can never be infinite. In fact, the gravity in the dead center is zero, which is the ultimate source of the instability of a black hole.
