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 . While the subject matter sounds like science fiction and is certainly inspired by it, his exploration is framed within the known laws of physics. 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.
