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?

Hahaha! That’s awesome. I love Virgin America. It’s, by far, the least annoying airline to fly in this country. Great cabin mood lighting, fairly comfortable seats (by airline standards) and crew is always cool and fun. I can’t believe I watched that whole video, though. Pretty entertaining.
I actually watched this entire video. Wow.
Skeptical at first, in the end, I liked it! I hope you guys got a couple free promo seats for posting this?
Meanwhile, back in the early 80’s I was dating a stewardess with Flying Tigers. She used to do a ‘flight safety’ take off routine before we got in the sack… now THAT was fun!
