Emergence

Once scientists have come to the conclusion that space-time is not fundamental, but emergent, now many things will change in physics and cosmology. One such change is that cosmologists can no longer hold that the universe has originated from nothing.

If an entity is emergent, then in general that will imply these three things:
1) The emergent entity cannot have any existence prior to its emergence;
2) The emergent entity (A) cannot emerge from just anything or everything or nothing; it can emerge from some particular entity or entities only (B); and
3) B must pre-exist before the emergence of A.
