It was a radical idea a century ago, when Einstein said space and time can be bent, and gravity was really geometry. We hear how his theories inspire young minds even today. At small scales, different rules apply: quantum mechanics and the Standard Model for particles. New experiments suggest that muons – cousins of the electron – may be telling us that the Standard Model is wrong. Also, where the physics of both the large and small apply, and why black holes have no hair.
