The first comment should maybe list the two abhorrent thoughts thus:-
There are currently no responses
1) Infinity
2) Nothing (or 0)
Since "nothing" is as equally qualified as "infinity" to be abhorrent. Both are meaningless, unimaginable, and undefined. infinity=0=undefined. How can anyone imagine complete nothingness? It's impossible so there is no justification for a symbol or word to describe it.
The idea that the multiverse cannot be "nothing" seems correct but poses two other questions. What then is the total number of particles in it? This cannot be zero nor infinite so must be a fixed number. Why that number? The only answer I can think of is that God chose it.
