Black holes are gravitational behemoths that dramatically twist space and time. Recently, they’ve also pointed researchers to a remarkable proposal—that everything we see may be akin to a hologram.

Inflationary Cosmology’s co-founder Andy Albrecht joins Brian Greene to examine cosmic mysteries from the highly ordered beginning of the universe to the possibility of a multiverse. This program is part …

Does your dog really think and feel like a human? Do our closest primate relatives have brains and emotions similar to ours? What about the storied intelligence of dolphins and singing humpback whales? And do other species hold surprises for us if we’re willing to look closely?

Professor Witten is a leading light of superstring theory and the only physicist to have won the vaunted Fields Medal, mathematics’ highest honor. Known for advancing a number of novel approaches in mathematics and physics, Witten opened up new vistas in 1995 when he unified five seemingly competing superstring theories into M-theory, which seeks to unify Einstein’s general theory of relativity with quantum mechanics.

Winner of the 2020 Nobel Prize in Physics, Sir Roger Penrose joins Brian Greene to share insights into black holes, general relativity, quantum mechanics, the mathematical road toward reality, the …

What we touch. What we smell. What we feel. They’re all part of our reality. But what if life as we know it reflects only one side of the full story? Some of the world’s leading physicists think that this may be the case.
