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?
