About this Episode

The new season has begun! We're back with an all-new series of question shows. In this week's episode, I provide a quick guide to seeing fireballs (bolides), which are the brightest meteors you can see (and sometimes hear). I explain the philosophy behind Dyson Spheres, and explain why dark matter can't be made out of antimatter.

00:43 How big are really bright meteors?
04:15 Are Dyson Spheres just pure fantasy?
08:19 What would it take to resolve features on Proxima B?
11:32 Could anti-matter be dark matter?
12:23 Is Jupiter a failed star?
13:15 Would the transmit method let us detect planets in Andromeda?
14:55 Disappearing stars?
17:38 No more Ewok Forest?
18:50 Could a collider create a dangerous black hole?
20:57 Should we find Oumuamua?
23:21 Could we detect techno signatures in Andromeda?
24:45 What's happening on Mars?
27:43 Could we detect an extraterrestrial war?
28:54 Will space-based power work?
30:43 Will Mars be a knowledge-based economy?
32:53 Will we ever live on Venus?
33:21 Is the Moon moving away?
34:09 Does NASA have new space suits for Artemis?
