Using the world's most powerful particle accelerator, the Large Hadron Collider, scientists have found that the quark-gluon ...

Physics says many laws should look the same forward and backward in time — but this particle doesn’t fully follow that rule. It shows a real imbalance that scientists call “time symmetry breaking,” ...

Learn how physicists recreated the early universe’s primordial soup, known as quark-gluon plasma, and discovered how it responds when particles race through it.

Our existence rests on a razor‑thin imbalance in the early cosmos. When the universe was young, matter and antimatter should ...

Columnist Natalie Wolchover checks in with particle physicists more than a decade after the field entered a profound crisis.
