Hey guyss

    It's been on my mind lately. Do we have any idea of what our universe is contained in? Whats containing it even?

    Is this question silly and not possible to know about??

    Hi Sorry!! :smile:

    It's not contained in anything.

    Its curvature is intrinsic.

    If it's an n-dimensional universe, then it's not contained in an (n+1)-dimensional universe (or higher) …

    the universe is all there is. :wink:

    So then how can it continue to expand? Wouldn't it need to get 'bigger' in order to keep expanding?

    Google on the 'no boundary condition'. Stephen Hawking provides a plausible explanation for a universe that is finite, but, unbounded.
