Why Does the Universe Expand?

    I kind of like the idea that as the edge of the universe is observed, it expands to fit that observation. "Observed" being in the same sense as the uncertainty principle. But there's also the idea of the universe or space as a kind of mesh that's stretching, not really growing.

    When I think about things at this scale, it really makes me feel minuscule.

      I like that too. It fits with the "there's no such thing as infinity, there's just really big numbers". So space is not infinite, it just doesn't have edges.
