von Neumann probes, Dyson spheres, exploratory engineering and the Fermi paradox
Future of Humanity Institute
Stuart Armstrong of the Future of Humanity Institute gives an Oxford physics talk on what exploratory engineering suggests about the Fermi paradox. He argues that von Neumann probes and Dyson spheres are plausibly buildable and asks what traces advanced civilizations would leave.
Cited as a source for the feasibility of colonizing the universe with self-replicating probes and for building a Dyson swarm from Mercury.
