#79 Avi Loeb

This episode is with a guest who I wanted to have on for a while. Avi Loeb is a Professor of Science at Harvard and was the chair of its astronomy department from 2011 to 2020. He has written 8 books, including the best-seller “Extraterrestrial”, and hundreds of research papers. Among many other things, he is well-known for his views on the Oumuamua interstellar object, and he now heads the Galileo project, which is looking for further such objects. One of his upcoming projects is an expedition to try to retrieve fragments of another interstellar object from the ocean floor. If all this wasn’t interesting enough, we also talk about academia, the way science is pursued, and how we can ensure our kids maintain scientific curiosity. Enjoy!   Avi's book "Extraterrestrial": https://www.amazon.com/Extraterrestrial-First-Intelligent-Beyond-Earth/dp/0358278147   Opportunities to learn more about space & the space economy: Check out the edX/EPFL Space Economy MOOC: https://www.edx.org/course/new-space-economy Do you want to specifically learn about investing in Space?
