Fascinating stuff.
I think it's sensationalist headline-grabbing speculation myself, and potentially dangerous talk:

"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.

This is the sort of thing that will have the public demanding that high-energy physics experiments be curtailed forthwith.
