Mug’s eye view: From ScienceDaily:
Perimeter Associate Faculty member Matthew Johnson and his colleagues are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science.
Never mind the big bang; in the beginning was the vacuum. The vacuum simmered with energy (variously called dark energy, vacuum energy, the inflation field, or the Higgs field). Like water in a pot, this high energy began to evaporate — bubbles formed.
Each bubble contained another vacuum, whose energy was lower, but still not nothing. This energy drove the bubbles to expand. Inevitably, some bubbles bumped into each other. It’s possible some produced secondary bubbles. Maybe the bubbles were rare and far apart; maybe they were packed close as foam.
But here’s the thing: each of these bubbles was a universe. In this picture, our universe is one bubble in a frothy sea of bubble universes.
That’s the multiverse hypothesis in a bubbly nutshell.
And this guy actually wants to test it? That makes no sense. The multiverse is implicitly believed by airheads everywhere just because it feels so good and sounds so right. What if it flunked tests? The multiverse fans would still believe it. Those of us who favour reality-based thinking wouldn’t really care if it passed or failed. I it failed, that’s just what we thought. If it passed, the scores would be reversed in a different universe. So there is no test that can decide the issue to the satisfaction of all parties. Follow UD News at Twitter!
