Interstellar Visitors in the Oort Cloud with Amir Siraj

Amir Siraj is the director for interstellar object studies at the Galileo Project and is currently studying Astrophysics and Astronomy at Harvard University under Avi Loeb. One of his new papers, Breakup of a Long-Period Comet as the Origin of the Dinosaur Extinction, details how a comet is the most likely answer for what caused the dinosaur extinction. Amir has also released papers on how the Oort cloud is likely full of interstellar objects. John discusses this and his take on why UAP and interstellar objects need to be studied. 00:00:00 Intro 00:00:42 Bio 0:01:12 A Comet Killed the Dinosaurs.. 0:05:02 That which creates life... 0:08:21 This reminds me of Shoemaker Levy.. 00:13:47 The Oort Cloud is interesting to Study 00:19:40 Does our Oort cloud interact with Proxima Centauri? 00:22:56 What about Planet Nine? 00:27:40 Did the Sun have a twin? 00:29:25 Could there be Exo-Artifacts in the Oort Cloud? 00:31:45 Goals of the Galileo Project 00:38:10 What if we never find another Oumuamua 00:43:25 The Galileo Project May Find Interstellar Meteorites 00:47:56 Why UAP should be studied 00:51:03 The past Scientists that studied UAP 00:53:40 How the Galileo Project will treat the subject Link: The Galileo Project https://projects.iq.harvard.edu/galil...
