Summary

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.

Hosted on Acast. See acast.com/privacy for more information.

0:10.3	We do define a black hole size as like the diameter of the event horizon.
0:18.8	Hello and welcome to the supermassive podcast from the Royal Astronomical Society with me,
0:24.6	science journalist Izzy Clark and astrophysicist Dr. Becky Smethurst. It's been a while since we

1:07.7	So along with all of the questions that are coming off in this episode,
1:15.6	we're also going to be bringing you a potted history of discovering black holes.
1:18.5	So Becky, are you ready?
1:21.0	No, I was born ready. I was so excited.
1:27.7	And obviously, Dr. Robert Massey from the Royal Astronomical Society is with us too.
