: : According to theory, Black Holes have infinte mass and infinte gravity. : : How then, can there be an event horizon? If the force of gravity from the Black : : Hole is infinite, then it would not dissipate with distance and therefore would be : : the same everywhere, for an infinite distance. If my understanding of infinity is : : correct, then Black Holes must have a finite mass and gravity if there is to be an : : an event horizon.....right? : actually I think you have the theory off a bit. : BH have (at their singularities) infinite density, : not infinite mass; for the reason you state in the : latter portion. : ) : this is why there are different sizes of BH as well. : For instance the gravitational field surrounding a : BH may as well be the mass of 50 of our suns, and : the event horizon be 1500 feet across. Thanks, the finite mass aspect clears a few things up. It still doesn't deal with the infinite gravity though. How is it possible to measure the dimensions of a gravitational field under conditions of infinite gravity? |
