    We know that space warps. We know it creates the effect of gravity. We know that it has energy in it. We know that particles pop out of it. Could Space be a thing? Could Space be what a singularity is made of? Could matter entering a black hole be crushed so hard that it gets turned into space? Could a black hole be a compact ball of space? Is there different kinds of space? Could we be living in a singularity? When our space expands could it be more space being created from our universe/black hole feeding on matter? Does the space inside us expand as our universe expands?

    That is a pretty big ball of hypothetical you got there.
    My answer is possible but not very likely to all the questions and I see no way to test any of them.

    There is an idea floating around that the inside of an eternal black hole is an eternal white hole and it would look a lot like a universe.
    White hole - Wikipedia, the free encyclopedia
    Black Holes and White Holes

    There are even suggestions the Big Bang was a white hole.

    Again there is no way to test it.

    Although I don't think the OP makes very much sense (if space is "stuff", what is it made of) I thought I would throw this in as it is quite a cool model for black holes:
    Waterfall

    But remember, kids: it is a metaphor.

    Thanks for the replies. And thank you to all scientists young and old who discover all these things for people like me to discover. I was just wondering because when it comes to black holes, the dividing by zero thing and the infinite density don't seem to make sense, so I thought maybe if we look at something that doesn't make sense, and see if there's any sense in it.

    You are right. It doesn't make sense. Which is why non thinks a singularity is a physical "thing" at the center of a black hole. We won't have a better idea until we have a theory of quantum gravity. String theory suggests this: Fuzzball (string theory) - Wikipedia, the free encyclopedia

    I liked the "waterfall" page. I still have an awful lot of questions about how it is possible for space to move though.

    Thanks for the link to the fuzzball black hole. I don't see why the density has to reduce and the expansion of the diameter has to follow the Schwarzschild radius though. To me it would make sense that the density remains the same.

    Simply because the Schwarzschild radius is what defines a black hole.

    Thanks, I will just have to categorise it under things I don't understand enough to make sense of them. When it comes to the really technical and mathematical part of science, I am just a baby. And I should apologise to Mr Schwarzschild, he probably measured thousands of black holes to see that phenomena.

    Actually, it is a purely theoretical derivation. No one has (yet) seen a black hole. (Although we have lots of evidence for things that are almost certainly black holes, based on the speed and distance of things orbiting them.

    I had a look up the Schwarzschild radius and found lots of maths which depended on lots of other maths. It seems like there are a lot of probabilities and possibilities when it comes to black holes.
