Episode 602: Q&A 110: Why Can't I Just Be Realistic About Mars? And More...

In this week's questions show, I explain why I don't think we always need to be realistic, if galaxies in the local group are bound together gravitationally, and what we should call Earth-moving equipment on Mars.

00:20 Be realistic.

04:24 Are galaxies in the local group bound?

05:56 Will gravitational waves give us advanced notice of collisions?

08:36 Will we ever be able to live outside on Mars?

10:16 Are we going to ruin Mars too?

12:42 Mars-moving equipment?

14:07 Could the Moon have an atmosphere?

15:51 Liquid water on the surface of Mars

16:49 Is there a business case for Mars?

19:17 What about nitrogen?

21:21 What will need to come from Earth?

23:06 Are there planets with less gravity than Earth?
