Q&A - Black Hole Special

Have black holes existed since the beginning of the Universe? Could we produce a black hole in the lab? Could we use gravitational waves to probe beyond the event horizon?

It's a black hole Q&A as Izzie put your questions to Becky and Robert. Plus, author and broadcaster, Marcus Chown, runs through a potted history of discovering black holes. His latest book on the same topic, A Crack In Everything, is out now: https://www.bloomsbury.com/uk/crack-in-everything-9781804544303/

The Supermassive Podcast is a Boffin Media production by Izzie Clarke and Richard Hollingham.
