This is of course huge, but the acceleration at the horizon of a black hole still goes to zero as M goes to infinity. This is because any physical signal will get infinitely redshifted at the event horizon, thus never reaching the outside observer. A black hole doesn't need an infinite mass to exert infinite forces (in the sense of acceleration). And this follows from a misconception that they have infinite mass. The resulting black holes are much smaller and denser, but they are still the same mass as the original star they came from. According to the standard theories of cosmology, the universe started with a Big Bang about 14 thousand million years ago and has been expanding ever since. A black hole with the mass of our sun would take half a trillion times the age of the universe to radiate enough energy to power a single light bulb. Address So it also has infinite gravity .
