Audible quoted,
" Our universe is simply one of those things that happens from time to time".
So you are saying it happened before. When? Where? The last time it happened -- what is that like now?
In "nothing" time doesn't exist anymore. How does something happen "from time to time" when time is meaningless. This statement is self-fulfilling like: "I assume therefore it is." Well of course!
Something from nothing, that is not the predominant line of thinking in the science community.
"Metaphysics" is physics that excede our own natural laws. This seems more credible. You should be debating Athelwulf on this subject. I will sit back and enjoy the show.
