Is There A Way To Test For The Existence Of Multiverses?

In a provocative press release from the Perimeter Institute for Theoretical Physics, in Ontario, Canada, physicists there are proposing a method of testing the notion that we may live in a multiverse; multiple universes existing in parallel, but separated forever in their own bubbles.

To do that, they intend to model the entire universe.

“We start with a multiverse that has two bubbles in it, we collide the bubbles on a computer to figure out what happens, and then we stick a virtual observer in various places and ask what that observer would see from there,” says Matthew Johnson, a physicist at the institute. “All I need is gravity and the stuff that makes these bubbles up. We’re now at the point where if you have a favorite model of the multiverse, I can stick it on a computer and tell you what you should see.”

The press release indicates that they are not trying to prove that multiple universes actually exist. They are just looking for the possibility of finding the observational clues that would point the way to an answer.

In the meantime. I'll just keep my traveling clothes packed.
