      Really great question, it isn’t one I can answer! I just really struggle to get my head around the whole universe not existing thing. Then on top of that, matter can’t be created or destroyed as far as I’m aware (see below)…so it kind of did exist, but not as a universe, as a singular thing in nothingness.

      Nope, my head is hurting just thinking about it.

      ‘The first law of thermodynamics doesn’t actually specify that matter can neither be created nor destroyed, but instead that the total amount of energy in a closed system cannot be created nor destroyed (though it can be changed from one form to another)’

      I don’t know – I’m not sure anyone does. In fact, there’s a point in time, called inflation and before that time no one really knows very well what happened at all.

      When the Universe was really young – just after the Big Bang – it suddenly started getting really big really fast. The time when this happened is called inflation. At the moment, we’re not even entirely sure why inflation happened – we don’t know exactly what caused it, or even exactly how it happened. The Big Bang happened before inflation, so that’s even harder to figure out.

      Some people think we’ll never find out what caused the Big Bang. I don’t really know what I think on that one, it’s a hard one.
