Remain Calm. All Is Well.

Before it shut down, the Large Hadron Collider ran for a little while and proved it probably couldn't create a black hole that would kill us all. But does another danger loom?

The LHC is cooled by superfluid helium (helium gas chilled until it's a liquid, which happens at about -453 degrees. Wear a scarf.), which is something called a Bose-Einsteinian Condensate. Scientists have made these condensates explode with magnetic fields, which of course the LHC makes use of, and they call them Bose supernovas, or "Bosenovas."

They used tiny amounts of their condensates, but the LHC uses about 185,000 gallons of superfluid helium, which would make for a much larger bang -- perhaps even an earth-shattering kaboom.

But we can rest assured of one thing -- being a Bose supernova, we know it's going to sound excellent.
