Dyson Spheres & Space Megastructures – Inhabiting Space with Isaac Arthur

My guest is Isaac Arthur — a theoretical space scientist, physicist, futurist and bold visionary of human expansion. He brings a mind-blowing level of research and storytelling to his series. We will focus on space megastructures, a form of future world-building on a scale that's almost unimaginable. From Dyson Spheres and Ringworlds to Shell Worlds and Artificial Planets. We touch on all this and more, all within known physics and largely within known technology, albeit at a mind-bending scale.
