Could Higgs boson spell the end of the universe?

Physicists recently confirmed that the Large Hadron Collider (LHC) at CERN, the particle physics laboratory in Geneva, had indeed found a Higgs boson last July, marking a culmination of one of the longest and most expensive searches in science. The finding also means that our universe could be doomed to fall apart. "If you use all the physics that we know now and you do what you think is a straightforward calculation, it is bad news," says Joseph Lykken, a theorist who works at the Fermilab National Accelerator Laboratory in Illinois. "It may be that the universe we live in is inherently unstable."

The Higgs boson helps explain why particles have the mass they do. The Higgs particle that the LHC has found possesses a mass of approximately 126 giga-electron volts (GeV)—roughly the combined mass of 126 protons (hydrogen nuclei). (One GeV equals a billion electron volts.)
