A thought just occurred to me.
The multiverse concept is where an infinite number of universes exist in which everything is possible, right?
So, if the multiverse existed and everything is possible, it would mean there is at least one universe in which the multiverse does not exist. Therefore, for that to actually be true in that universe, then there cannot be any other universes. So, the multiverse would not exist. It could be said thus, if it existed it would not exist.
Paradox?
On the 7th day, God was arrested.
