In the very weird world of quantum mechanics, which describes action on a subatomic scale, random fluctuations can produce matter and energy out of nothingness. And this can lead to very big things indeed, researchers say.

“Quantum mechanical fluctuations can produce the cosmos,” said panelist Seth Shostak, a senior astronomer at the non-profit Search for Extraterrestrial Intelligence (SETI) Institute. “If you would just, in this room, just twist time and space the right way, you might create an entirely new universe. It’s not clear you could get into that universe, but you would create it.”

“So it could be that this universe is merely the science fair project of a kid in another universe,” Shostak added. “I don’t know how that affects your theological leanings, but it is something to consider.”
