Older than the hills
Here's an interesting thought... Perhaps a Black Hole is something like a giant rice cannon. The immense gravitational force of a Black Hole draws in all the planets and stars and light into the center and compresses it. On the other side of the Black Hole, everything that was compressed gets shot out, expelled and expands into the makings of another universe.
You are referring to a White Hole.
