Space is infinite and eternal, you only move in reference to other objects<br>and if you take everything out of it, stars, planets, matter and so on, then space will be pure nothingness, and the one and only true infinity. Only the effects of black holes have been observed and never a black hole itself. Big bang is a theory, and nobody knows if it actually happened, which it most likely didn't, and even if it did happen, there was always a before because space is eternal, it will always exist, because it doesn't really exist since it is pure nothingness.
