Will the universe end in an anti-bang?

I just read a fascinating article today at bbc.co.uk in which it is theorized that, if certain quantum-level characteristics related to the Higgs boson exist, that at some point in the future a bubble of vacuum will appear. The bubble will then expand at the speed of light and sweep away everything in its path.

It sounds like an anti-bang, the inverse of the big bang from which all energy and matter flowed out from a central point and is still moving outwards today.

“It turns out there’s a calculation you can do in our Standard Model of particle physics, once you know the mass of the Higgs boson,” explained Dr Joseph Lykken.

“If you use all the physics we know now, and you do this straightforward calculation – it’s bad news.

“What happens is you get just a quantum fluctuation that makes a tiny bubble of the vacuum the Universe really wants to be in. And because it’s a lower-energy state, this bubble will then expand, basically at the speed of light, and sweep everything before it,” the Fermi National Accelerator Laboratory theoretician told BBC News.

Data gathered by two independent detectors observing this subatomic debris determined the mass of the Higgs to be about 126 gigaelectronvolts (GeV).

That was fascinating, said Prof Chris Hill of Ohio State University, because the number was right in the region where the instability problem became relevant.

“Before we knew, the Higgs could have been any mass over a very wide range. And what’s amazing to me is that out of all those possible masses from 114 to several hundred GeV, it’s landed at 126-ish where it’s right on the critical line, and now we have to measure it more precisely to find the fate of the Universe,” he said.
