George Smoot on Dark Matter, Cosmology and Gravitational Lensing

How can we measure the universe—and determine what it is made of?

Nobel Prize-winning astrophysicist George Smoot joins Robert Lawrence Kuhn to explore precision cosmology, from measurements of the cosmic microwave background to dark matter, dark energy, and the expansion of the universe. They discuss how gravitational lensing is becoming an increasingly powerful tool for probing the cosmos and investigating what dark matter might actually be.

Smoot also looks ahead to new observations and technologies that could help answer some of cosmology’s biggest remaining questions.
