EPTDoes this mean that a Blackhole is literally so heavy and so strong that it literally tears through space. Like if an object was to fall through the rubber because it was so heavy? That would be the equivalent of a black hole in space?

The plain fact of the matter is that we don't know. We don't know the effect infinitely strong gravity has on space time. I'm almost certain though that space time as we know it is pretty much completely different at a singularity point. In your example it's equivalent to dropping something so heavy on the rubber that it stretches it to it's ABSOLUTE breaking point such that a single iota more of force would cause it to tear. Blackholes could stretch it that for or possible completely tear it, we're not sure. | ||

So pretty much there are still many mysteries regarding to the black holes. | ||

I think you mix something up here. gravitational pull is an acceleration it can not have the speed of light. what you mean is the escape velocity of a black hole exceeds the speed of light, right? | ||

some people call it a rip in space-time, some people call it a hole so deep it's impossible to get out what motiva's probably referring to is a singularity (which may or may not actually be at the center of a black hole), but "gravity is infinite" and "time is infinite" are misleading and don't really make sense | ||

We can't directly observe them because all forms of measurement (the easiest one being light) are absorbed in to it. I can't help myself. In your first sentence the words everything and completely are absolutely not true. Well completely theoretical in the sense that friction and gravity, or evolution are theoretical. Relgious folk always have that problem withevolution. a Scientific theory is something very different than a non-scientific theory. We do know some things about blackholes, and we know some of it with a very great deal of certainty. We can determine the charge, mass, and spin of a black hole. We have determined details about the entropy of blackholes, and how something with such a distorted spacetime continuum can even have a charge. Obviously there are problems gathering direct evidence due to the nature of the problem, but to say we don't know anything because -all- forms of measurement are absorbed into is not only just wrong, but a great disrespect to the majesty of science.
