BBC News - Cosmos may be 'inherently unstable'
So yeah, apparently the universe expands till it can't no more, and then a new takes its place during the implosion of the old one. Whatever is outside of the mystical barrier of the universe is really just the remains of the old one, and probably outside of that is another one. This is all according to the Higgs Boson research. Damn you universe, you scary.Scientists say they may be able to determine the eventual fate of the cosmos as they probe the properties of the Higgs boson.
A concept known as vacuum instability could result, billions of years from now, in a new universe opening up in the present one and replacing it.
It all depends on some precise numbers related to the Higgs that researchers are currently trying to pin down.
A "Higgs-like" particle was first seen at the Large Hadron Collider last year.
One idea that it throws up is the possibility of a cyclical universe, in which every so often all of space is renewed.
"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.
It was not something we need worry about, he said. The Sun and the Earth will be long gone by this time.
If the calculation on vacuum instability stands up, it will revive an old idea that the Big Bang Universe we observe today is just the latest version in a permanent cycle of events.
