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?

I think they could have done without the infrared, or at least toned it down alot. Half the land looking red just doesn’t look right.
Time’s cycles of motion, in rotations through Space,
In cloud-draped swirls of air, and tidal-flows of seas.
A World’s animating rhythms in life’s daily heart-beat.
Through the movements of seasons, in turn of year.
(More dramatic and impacting, if this had been done in
natural-color time-lapse, I agree.)

Love it. Awesome to see that arc of color switch sides when the planet’s nearly all in darkness.
