Theoretical Physicist Andrew Strominger explains what exactly black holes are and how they could tell us about the beginning of the cosmos.


In this episode, Andrew discusses the questions behind black holes, the strange physics at their event horizon, what they reveal about the nature of space and time, and how he, Stephen Hawking, and Malcolm Perry helped develop the theory that "soft hairs" may store information on black holes' surface. From leading minds like Einstein, Hawking, and Strominger, our understanding of these celestial bodies is constantly evolving, and we still have so much to learn. This one is going to be cool!

Are You A Charlotte?

Are You A Charlotte?

In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
