How We Build Telescopes to Explore the Early Cosmos | Brian Keating

Did the Big Bang really happen? Telescopes, dark matter & cosmic origins explored.

Join cosmologist Brian Keating as we explore the mysteries of the universe, from building telescopes at the South Pole to measuring the polarization of the cosmic microwave background and chasing signs of gravitational waves. We discuss Galileo’s influence, cosmic inflation, and how the Nobel Prize could be changed to better reflect the way we do science.
