Cosmologist Bernard Carr is famous for his work on black holes, the anthropic principle and the multiverse, and his collaborations with Stephen Hawking. But over his illustrious 50 year career, he has also been involved in psychical research -- applying scientific techniques to test telepathy, astral projection, and to investigate haunted houses. This Halloween special edition of the podcast features Part 1 of our interview with Carr, discussing primordial black holes, the notorious 1970s Enfield poltergeist case that Carr investigated, and more.
