What do you mean by this, the movement of the universe around whatever bigger is outside, or the universe of all the galaxies around the universe?

If it is the movement of the universe as a whole, then it's stupid to think that. Time, space, gravity, matter exist inside this universe, we don't even know if it exists at all in other universe, or even if the universes exist, or, even being more exact, we can't be sure that these properties exist in our universe, or even that our universe exists. But as gravity only exists inside the universe, it can't be between universes. Time, or space, or matter...
