Summary

Do we see black hole mergers as a result of galaxy mergers? What did the night sky look like to the dinosaurs? Is a gas giant just a rocky planet with a huge and dense atmosphere? Do all orbits eventually end up in resonance?

Hello and welcome to another bonus episode of the Supermassive podcast from the Royal Astronomical Society.

0:08.7

With me, science journalist Izzy Clark, astrophysicist Dr. Becky Smethurst and the Society's deputy director, Dr. Robert Massey.

0:17.4

Yeah, this is a place where Robert and I take on even more of your questions from the supermassive mailbox because let's face it, you all have such good questions, you keep sending them in, there's just too many, we can't fit them all in the normal episodes. First of though, I just want to say a big thank you so much for all the lovely messages about our multiverse episode from last year. Like, they were just fab, weren't they, to read?

0:39.3

It was so nice to hear that you all enjoyed it.

And you'll be pleased to hear that listener, Wendy Entwistle,

So I hope she doesn't almost crash her car when she hears this one as well.

0:53.2

Yeah.

1:11.0

That's something to bear in mind, yeah. Yes, we do not take any responsibility. No, I'm joking. Yeah. That's not liable. Thank you. Okay, Robert, let's go on to some questions.

1:34.0

and having to wait a whole month again for a new one.

1:36.5

Yeah, a lot of people complain about that, actually.

1:38.2

Two weeks now because we give you bonuses.

1:41.8

My question is, why do some objects end up in orbital resonance such as the Galilean moons

1:48.1

and others such as the planets in the solar system and any of Jupiter's or Saturn's other moons

1:53.2

orbit at other more random seeming periods? Do all orbits eventually end up in resonance,
