LHC May Have Found Crack in Modern Physics
In late 2008, a few onlookers believed that the Large Hadron Collider (LHC) would bring the end of the world. Three years later, our planet remains intact, but the European particle smasher may have made its first crack in modern physics.
If this crack turns out to be real, it might help explain an enduring mystery of the universe: why there’s lots of normal matter, but hardly any of the opposite—antimatter. “If it holds up, it’s exciting,” says particle physicist Robert Roser of the Fermi National Accelerator Laboratory in Batavia, Illinois.
To understand why physicists are excited, look around: We’re surrounded by stuff. That might seem obvious, but scientists have long wondered why there’s anything at all. Accepted theories suggest that the big bang should have produced equal amounts of matter and antimatter, which would have soon annihilated each other. Clearly, the balance tipped in favor of normal matter, allowing the creation of everything we see today—but how, no one’s sure.
