Is it possible that dark matter could be subatomic particles in this universe quantumly entangled with counterparts across multiple alternate universes? If so, how could we test this?

Why should matter "condense" shortly after BB? The energy collected even in subatomic particles must have come from a very large volume even in the compressed early universe.

If a particle and an antiparticle "pop" into existence, and immediately annihilate each other, doesn't that still violate conservation of energy? Shouldn't they release a burst of pure energy? That's how regular particles work, right?
