Episode 695: Q&A 130: Does the Dark Forest Explain the Fermi Paradox? And More... Universe Today Podcast

- Astronomy
In this week's questions show, I talk about the Dark Forest theory in the Three-Body Problem series of books. Is it a compelling answer to the Fermi Paradox? How much of a risk is dust to interstellar travel? Is black hole evaporation negated by black holes absorbing additional material and energy?
00:00 Start
00:46 Is the Dark Forest a reasonable answer to the Fermi Paradox?
04:05 How much dust is in interstellar space?
05:57 Can we go faster than the Voyagers?
08:24 Are black holes gaining mass faster than they're evaporating?
10:07 Is abiogenesis happening right now?
13:47 How do we calculate the habitable zones around other stars?
15:45 How close can binary stars be and still be habitable?
17:50 Could we find debris in the Lagrange Points?
19:27 Can gravitational waves let us see past the CMB?
22:07 What is a galactic halo?
23:49 Are there gas dwarfs?
