The Origins of the Big Bang

There are scientific speculations about where this initial, so the root of the Big Bang came from. It's not something that we can prove with observations or experiments because we can't actually look outside of our universe. There is still a law, there is still, it's empty, but there is still structure, there's a structure to it. So when a physicist talks about nothing, the closest to nothing you can get is this so-called quantum vacuum.
