At CERN’s Large Hadron Collider — the world’s biggest science experiment — physicists have uncovered clues to one of the oldest mysteries in existence: why the universe didn’t annihilate itself seconds after the Big Bang.
According to physics, matter and antimatter were created in equal amounts at the birth of the universe. But they destroy each other on contact. If everything were perfectly symmetrical, the universe should have ended in a flash of energy with no galaxies, no stars, no Earth, and certainly no humans.
Yet we’re here.
And something tipped the balance.
CERN’s new experiments are revealing tiny differences — called CP violation — between matter and antimatter particles. These differences, though unimaginably small, may have allowed matter to survive while antimatter vanished. In other words, the reason you exist may be hidden inside the behavior of subatomic particles dancing inside the collider’s magnetic rings.
If scientists solve this puzzle fully, it will be one of the greatest discoveries in human history — the explanation for why there is something instead of nothing.
