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.
