Where does Planck Cosmology?
In black holes?
- The point black hole singularity?
- Or the ring singularity?

For the time being, mainly what we have is just Liddle, Ch. 14: Direct link.

Plus some supplements/complements.

Actually, I think point origin (AKA Big Singularity) disappears with inflation, I think.
