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?

\\n\\n

00:00 Start
\\n01:01 How much gravity makes spaceflight impossible?
\\n04:40 Could a rival shoot down a rocket during launch?
\\n07:07 Should I apologize for advocating for SLS?
\\n11:50 Do photons experience time?
\\n13:42 Can you see Earth\'s lights from the Moon?
\\n15:28 Can we detect exoplanets with their magnetic fields?
\\n17:27 What missions do I wish were never cut?
\\n20:21 Does finding life mean we\'re doomed?
\\n22:45 Are galaxies orbiting something bigger?
\\n23:42 Can a star collapse directly into a black hole?
\\n25:36 Should we move away from complex telescopes?
\\n29:03 What does it cost to use Hubble?

\\n\\n
