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 …

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.

Just a handful of technologies deserve to be called “game changers”—and CRISPR-Cas9, the new gene-editing tool, is one of them. Discovered just three years ago, CRISPR is sweeping through labs around the world and researchers are already using it to experiment on diseases.

Cosmologist Hiranya Peiris joins Brian Greene to discuss pressing cosmological mysteries spanning dark matter, dark energy, the expansion rate of space, and the possibility of a multiverse.

Scientists have waited a generation to see the stunning images that the James Webb Telescope is now delivering. In a live online Q+A, Brian Greene speaks with Nobel Prize-winner John …

The inflationary theory of cosmology, an enduring theory about our universe and how it was formed, explains that just after the Big Bang, the universe went through a period of rapid expansion. This theory has been critical to understanding what’s going on in the cosmos today.
