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

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?
