Can We Really Get A Universe From Nothing?
The answer is "no", apparently. If you take the meaning of the word "nothing" literally. And why shouldn't you? That's the bigger question after all, isn't it?
Leaving that aside, the universe/the big bang did indeed come from something else. This something else is supposedly "quantum foam" (the imprint of which can be seen blown up from the quantum scale to the largest scale in the cosmic microwave background). Well, I guess that satisfies it. But does it? Isn't there yet another process that must have given rise to the quantum foam itself? Otherwise, how could one take quantum foam to "just be"? If the quantum foam represents the totality of all that exists, how could this total existence be self-sufficient and self-contained? Surely, yet another process must be responsible for it. And so on we go unto infinity.
