Stephen Hawking: Research on the ‘God particle’ could cause space-time to collapse

In the preface to a new book, Starmus, acclaimed theoretical physicist Stephen Hawking writes that the so-called “God particle” could become unstable and cause a “catastrophic vacuum decay” that would lead to the collapse of time and space, The Sunday Times reports.

“The Higgs potential has the worrisome feature that it might become metastable at energies above 100bn gigaelectronvolts,” Hawking writes. “This could mean that the universe could undergo catastrophic vacuum decay, with a bubble of the true vacuum expanding at the speed of light.”

“This could happen at any time and we wouldn’t see it coming.”

The successful discovery of the Higgs particle has led to calls from within the scientific community to create larger, more powerful supercolliders than the Large Hadron Collider at Cern, where scientists discovered the Higgs boson.

Many in the scientific community are upset with Hawking — not because he is incorrect, but because such statements from a scientist of his eminence could dissuade the public from funding experiments like those at Cern in the future.

In his preface, Hawking stresses that the possibility of the Higgs boson behaving in such a way is highly unlikely — and that creating the conditions in which the particle would is impossible given the current state of technological development.

“A particle accelerator that reaches 100bn GeV would be larger than Earth, and is unlikely to be funded in the present economic climate,” Hawking writes.

Don't eat the forbidden fruit!

Hmm. If space-time was to collapse next year, would we cease to exist instantly, RIGHT AWAY, NOW, with all the rest of the universe's past, present(s) and future?

Like you said, I guess if it was to collapse, it would already be over.

I think, what he was worried is the fact that we will make great amount of anti-matter. That is not good at our present technological and social level. But it is necessary for the future. So, when the time comes, people will go for it.....but not now...

It has nothing to do with antimatter. He was talking about a local minimum, as described in calculus, and the possibility of the universe reaching either a lower local minimum or a global minimum energy level, emitting energy in the process.

So, if people are afraid, due to Hawking, does that mean we still have LHC with larger and bigger energy transfers?

I'm not sure what you're asking. The LHC doesn't operate at high enough energies to pose a risk, and higher energy interactions have been observed in outer space. It's just a theoretical idea anyway, not worth worrying about.
