Sarah T. Stewart: Where did the Moon come from? A new theory

11:10 minutes · Filmed Feb 2019 · Posted Mar 2019 · TED Salon U.S. Air Force

The Earth and Moon are like identical twins, made up of the exact same materials -- which is really strange, since no other celestial bodies we know of share this kind of chemical relationship. What's responsible for this special connection? Looking for an answer, planetary scientist and MacArthur genius Sarah T. Stewart discovered a new kind of astronomical object -- a synestia -- and a new way to solve the mystery of the Moon.

Inspiring talk! The two candle-problem images helped me understand when rewards work and when they don't. How do we continue to ignore this social study? My place of work, like many others, uses the 'carrots and sticks' method. I am spinning with ideas on how to use this new learning in my work, and making plans to share it with others -- but I'm also thinking about it in my personal life as well. This is about people, after all.”
