More Than One Universe? Bring ‘Em On!

From Robert Krulwich at NPR:

“A lot of folks get stumped when they hear the word “universes,” the plural. A universe sounds like it means everything there is and since common sense tells you there can't be more than “everything there is,” universe should remain a singular. A one and only.

But what if….? say the quantum physicists … What if … deep down, down below the level of atoms and protons and neutrons and quarks, down at the very bottom of things, down where nature is “fundamental,” what if everything down there is in a constant jitter, constantly creating and destroying and throwing up new combinations? What if the fundamental laws of nature not only allow the possibility of a universe different from ours, but allow there to be more than one, maybe three, or 10 or a gazillion universes?”
