That was one very hight in my list of questions to ask "if a day I find someone that knows everything" many years.

The answer would be (not to ST but to the one that asked) that it has not meaning in a computer simulation like the one we are in (and our Higher Selves are the ones running the simulation). Imagine a 3D game of a computer and ask about the "nothing" in that computer universe. It has no sense, the "nothing" simply don't exists in a simulation. Out the 3D Game is nothing? No, out there is the real world. The same with the Universe that is a Creation, a 3D Game. The search of who is out of the 3D Game is the principal search of every being. All you do has that goal and you feel bad when you are not searching it.
