3:00Now PlayingWe made this video in partnership with Unlikely Collaborators.
David Eagleman, PhD, Brian Greene, PhD, and Dean Buonomano, PhD, explore one of science’s strangest questions: what is time?
From Einstein’s spacetime theory to the brain’s internal clock, they examine whether time is an external property of the universe or a mental construct. By connecting physics and neuroscience, they unpack the idea that how we experience time may differ entirely from how it actually works.
