    Okay, so I had a theory a few days ago, and after typing it out onto my computer and trying to prove it wrong, I decided to submit it here. This is my theory:

    My theory about the universe is that the universe always existed, always will exist, etc, and there is a ‘mega-massive’ black hole at the centre of the universe, and it keeps eating matter, until eventually becomes so massive that it slows down the edge of the universe.
    The black hole would be, by now, incredibly huge, so it would not allow for any matter outside of the black hole, except the ‘edge of the universe’. It would pull in the sides of the universe, until it finally reaches one point, much like a singularity.
    Now, the heat inside this point would be very, very, high, so high that the particles would be moving at around the speed of light, if not, higher. If one of these particles hit another, it would make the particle expand to something around the Planck mass, so it would cause a huge acceleration for the edge of the universe, and a lot of the matter in the singularity would just stay in the centre, (allowing another black hole to form), and the rest would explode outwards, ready to create a new universe, and for it to repeat.

    Is this feasible? I must admit I am not great at astrophysics or whatever.

    Your idea is imaginative and that is important in science. Unfortunately it lacks evidence in support of it and equally crucial there is evidence against it.

    Current belief is that there is no centre to the universe. Black holes do not possess any more gravitational power than the matter from which they are constituted so, contrary to popular ideas, they do not 'suck in' matter. There is clear evidence that not only is the universe expanding, but the rate of expansion is increasing. All these points coint against your hypothesis.

    So, on balance not feasible, but keep thinking and - perhaps more important - read up a little more on current theory. I think it is true to say that practically all new theories that work have been proposed by someone who understood the old theories very well.

    I'm certain this has been mentioned before, but it is interesting to look at dictionary definitions of the word "theory".
    I was looking at the online Free Dictionary just now, and the meaning of the word, when used in scientific disciplines, would seem to be very different from the meaning when used in non-scientific "everyday" speech.
    Of course this is a Science Forum and so I would agree with John Galt when he uses the word "idea" to refer to kwongo's "theory".

    Kwongo your idea is very imaginative. As we know we have nothing but theories to run with in these cases and so that is where your theory will lie until proven unfortunetly. Most interesting idea though......

    Maybe. Maybe not. We don't know. The rest is highly imaginative but that's about all. I hope you stick around to learn more about what we currently know about things like the universe and black holes.

    and there is a ‘mega-massive’ black hole at the centre of the universe
    Well apart from the fact there is no center and there is no evidence for such a black hole ...

    and it keeps eating matter, until eventually becomes so massive that it slows down the edge of the universe.
    How can it keep eating matter; surely, once all the matter nearby is gone it will stop growing? When black holes are absorbing matter they are highly visible because the infalling matter emits massive amounts of high energy radiation.

    And how would it "slow down the edge of the universe"? And what does that mean? And are you aware that there is no edge (as there is no center).

    The black hole would be, by now, incredibly huge, so it would not allow for any matter outside of the black hole, except the ‘edge of the universe’. It would pull in the sides of the universe, until it finally reaches one point, much like a singularity.
    So it sounds like you imagine the black hole has absorbed all matter? So how come we are still here?

    Now, the heat inside this point would be very, very, high, so high that the particles would be moving at around the speed of light, if not, higher. If one of these particles hit another, it would make the particle expand to something around the Planck mass, so it would cause a huge acceleration for the edge of the universe, and a lot of the matter in the singularity would just stay in the centre, (allowing another black hole to form), and the rest would explode outwards, ready to create a new universe, and for it to repeat.
    I'm afraid none of that makes much sense.

    Or ... we can evaluate ideas like this (speculations or hypotheses) against the evidence. If they stack up against that, then they may be promoted to the level of theory.
