49 The Hole Shebang - Black Holes with Dr John Regan

This week in the function room, the hole shebang. A bit about Black Holes with Dr John Regan. Royal Society - SFI University Research Fellow in the Department of Theoretical Physics. we caefully scrape the surface of the topic of black holes without hopefully getting sucked in and destroyed by the weight of the topic. John tells me how he got into black holes why he can't really get out, how Einstein nearly got it wrong and then got it right with a little help from his friends, what the LIGO saw, what it's like as a black hole expert to look at the first photo and is there a black hole in the room with us right now? There's the usual whiteboard nosing and of course I ask about time travel.
