An interview with Andrei Linde, Harold Trap Friis Professor of Physics at Stanford, about the development of modern cosmology and the interplay between theory and observations in answering some of the open questions about our Universe. 

An interview with Jim Peebles, one of the world's foremost cosmologists and an emeritus professor at Princeton University, where since 1984 he was the Albert Einstein Professor of Science. With Robert Dicke he predicted the existence of the cosmic background radiation while he largely contributed to establishing the big bang model and furthering our understanding of the universe.

Licia Verde discusses how our cosmological observations can be used for constraining interesting physical quantities and neutrino properties are a particularly hot avenue to pursue.
