About this Episode

In this week's live questions and answers show, I speculate what kind of civilization could be permanently stuck on the surface of their planet, if rival nations could shoot down each other's spacecraft, and how do I really feel about the Space Launch System?

00:00 Start
01:01 How much gravity makes spaceflight impossible?
04:40 Could a rival shoot down a rocket during launch?
07:07 Should I apologize for advocating for SLS?
11:50 Do photons experience time?
13:42 Can you see Earth's lights from the Moon?
15:28 Can we detect exoplanets with their magnetic fields?
17:27 What missions do I wish were never cut?
20:21 Does finding life mean we're doomed?
22:45 Are galaxies orbiting something bigger?
23:42 Can a star collapse directly into a black hole?
25:36 Should we move away from complex telescopes?
29:03 What does it cost to use Hubble?
