With his General Theory of Relativity, Einstein illuminated the grand expanse of the cosmos, but he was also instrumental in developing quantum mechanics for describing the microworld. In Einstein’s day, …

Thirty-five years ago string theory took physics by storm, promising the coveted unified theory of nature’s forces that Einstein valiantly sought but never found. In the intervening decades, string theory …

Extra dimensions of space — the idea that we are immersed in hyperspace — may be key to explaining the fundamental nature of the universe. Relativity introduced time as the fourth dimension, and Einstein’s subsequent work envisioned more dimensions still — but ultimately hit a dead end.

Join Brian Greene and Juan Maldacena as they explore a wealth of developments connecting black holes, string theory, quantum gravity, quantum entangelment, wormholes, and the holographic principle. This program is …
