Episode 788: Q&A 172: Why Do We Assume Extraterrestrials Will Be Hostile? And More...
In this week's questions and answers show, I explain why people might see extraterrestrials as a threat. What could we learn about astronomy if we lived at the center of a supervoid, and how far away are we from the Big Bang?
00:00 Start
01:10 Why do we assume extraterrestrials are evil?
07:40 Could we see anything from within a supervoid?
09:40 What if we lived near the Big Bang?
10:25 Will James Webb ever look at Earth?
11:34 What's the benefit of helium 3?
14:47 Can we take animals to Mars?
17:13 Will machines do all our exploring?
20:36 Was the Universe as small as a grapefruit?
21:42 Does the expansion of the Universe travel faster than the speed of light?
23:04 Should we be worried about rogue black holes?
25:14 When will we see the calibration star from James Webb?
27:08 Did the Three-Body Problem change my opinion about extraterrestrials?
30:07 Could there have been many Big Bangs and other universes?
31:52 What is the Oort Cloud?
33:00 Why do stars like Sirius shimmer?
35:15 Will James Webb see the first stars?
