Once you cross a black hole’s event horizon, there’s no going back. But inside, could creating a singularity give birth to a new Universe?

For hundreds of millions of years, a cosmic fog blocked all signs of starlight. At last, JWST found the galaxies that cleared that fog away.

The ANITA experiment found cosmic rays shooting out of Antarctica. One interpretation claims “parallel Universes,” but is that right?
