Dark energy is cosmology’s biggest mystery—an anti-gravitational force that confounds the conventional laws of physics. It makes up more than two-thirds of the cosmos, but science is still grappling to explain what dark energy actually is.

The powerful James Webb Space Telescope–the successor to the Hubble Space Telescope–promises insight into profound questions that have dogged philosophers and astronomers for millennia. What is the origin of the …

Stuntman and special effects coordinator Steve Wolf shows how actors can fall from a 20-story building without injury and how houses can be set ablaze safely in movies…all through science. …

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.

Pioneering computer scientist and physicist Stephen Wolfram joins Brian Greene to discuss the interplay between physical law, computation, and artificial intelligence.
