Still hoping for micro-black holes as the solution as the early universe density must have been enough for some to form. Also, where's the anti-matter gone?

- snarkconjecture 3y agoBoth of those are pressureless, so they could be dark matter but not dark energy. Except that primordial black holes are ruled out (as 100% of dark matter) by various observational bounds, and antimatter would be just as visible as normal matter and not "dark" at all.
- superjan 3y agoWell, if we suppose all the anti-matter is in those black holes, we kill two birds with one stone. It’s ridiculous, I know, but your remark made me realize that an anti-matter black hole is essentially indistinguishable from a ‘normal’ one.
- BlueTemplar 3y agoCould just be the anthropic principle at work : in a ridiculously large universe, we live in a tiny fraction of it where local fluctuations in the respective distributions of matter and antimatter have happened to favor matter. (And the observable universe is even smaller than that.)
