@Night Ripper,
Quote:It was just an example. You're missing the point. It's still the same idea. Suddenly there are two particles where before there were none. Suddenly there is a universe where before there was none.
Again, this notion that the physical comes from nothing( whatever this means) can be reject. Never mind that "something coming from nothing" is itself a bit impossible. There is also many conceivable alternatives. Our universe could come from a mother universe, a collision between between branes etc. I don ` t see the necessity that the universe need to come from nothing( whatever this means).
Quote:But 2-3 don't solve the mystery, why something instead of nothing. Saying that we come from another universe or another state doesn't solve anything.
It does solve the original question, but it does presuppose something else. To solve why our universe exist by positing another, mother universe will lead us to presuppose this mother universe.
Quote:That's like saying God did it. The question remains, why did that universe exist, why did that state exist, why does God exist?
Saying that god did it would not solve the original mystery because the existence of god itself be a mystery. Why does god exist instead of nothing etc?
To answer the question "why does anything at all exist". You need to realize
this is a different question from "why our physical space-time manifold exist?"
The" everything" need not be the same as our space-time manifold. There could be something not in our space-time manifold that generates us.
My own answer is that there had to be something that exist. It could be god, it could be a set of laws, or metalaws, or some type of matter. Again: i am not sure.

I completely understand.

If you listen to the whole thing. I think you realize more fundamental question is not "where the bb come from?", or " why something exist?", but rather " why this set of laws?" The reason is that the laws is what import order. My own feeling is that there are other laws, meta laws. In fact, all logically possible set of laws would describe a universe, or a multiverse.
