Today’s long-anticipated announcement by Fermilab’s Muon g-2 team appears to solidify a tantalizing conflict between nature and theory. But a separate calculation, published at the same time, has clouded the picture.
Spurred on by quantum experiments that scramble the ordering of causes and their effects, some physicists are figuring out how to abandon causality altogether.
A new study shows that extreme black holes could break the famous “no-hair” theorem, and in a way that we could detect.
The result highlights a fundamental tension: Either the rules of quantum mechanics don’t always apply, or at least one basic assumption about reality must be wrong.
Cora Dvorkin discovered new possibilities for what dark matter could be. Now she’s devising unorthodox ways to identify it.
