    never took the course in college

    anyway, serious question;

    if we're an expanding universe, doesn't that make us a white hole?...for instance, if outside our universe, matter is being expulsed from our origin

    we're supposed to start to collapse eventually as well, which would mean if we were outside our universe, our universe would be either a star or white hole as we're expanding, and a dead star when we started to collapse

    just a theory from a layman with no education in physics

    Seems like its a supported thoery. Makes sense on a theory basis.

    I swear I came up with that theory about ten years ago, when was that first proposed?

    When white holes were first postulated.

    The idea is theoretically supportable but there are many things we don't yet know or understand about the universe, so it is difficult to justify one way or the other definitively.

    I wrote a paper on white holes in my astronomy class in university :) Quite a fascinating subject, so many possibilities. Btw, if you have time, check out some of the NOVA tapes/dvd's with Dr. Stephen Hawking and his view on things. He is not quite infallible, but he has a very broad insight on the subject of space/matter/black holes and the like.

    The wiki piece seems to suggest that there is a central black hole of inordinate size, the origin so to speak. This has not been observed afaik and there are no gravitational indicators to suggest its existence. But it is something we talked about in great detail in uni.
