Irish writer-turned-cosmologist Julian Gough and I discuss.In this podcast, learn about: where the term "black hole" came from, how black holes and the Big Bang seem suspiciously like one another, why our universe looks like it comes from an evolved history of parent universes, how universes can evolve their parameters of physics through offspring universes (from their black holes), how cosmological evolution through black holes explains the complexity of the early universe, the nature of dark matter, why the universe could be purposeful, and much more...Timestamps:00:00 The Birth of Universes from Black Holes03:54 Could universes actually emerge out of black holes?05:38 How this idea explains the complexity of our cosmos09:05 What happens at the singularity of a black hole?11:40 Three-Stage Cosmological Natural Selection15:03 The Mechanism of Black Hole Production17:59 Moral Implications of Creating Universes20:54 The Future of Black Hole Research31:55 The Evolution of Black Holes and Stars35:11 Exaptation: Evolution's Ingenious Adaptation39:05 The Chemistry of Life and Stellar Evolution40:55 The Role of Supermassive Black Holes in Galaxy Formation51:13 Spiral Galaxies: A New Perspective01:04:14 The Universe as an Evolving Organism01:05:45 Galaxy Formation and Supermassive Black Holes01:08:36 Critique of Mainstream Cosmology01:10:13 The Sociological Implications of Cosmology01:11:41 Evolutionary History of Electrons01:14:37 Structure in the Universe: Past vs Present01:17:03 Purpose in the Universe01:19:21 Dark Matter and Self-Organizing Systems01:20:55 Interacting with Parent Universes01:24:11 The Future of Cosmological Theories01:28:15 Creating a New Field of StudyFind Julian:• Substack: https://theeggandtherock.com/• Blowtorch Theory: A New Model for Structure Formation in the Universe: https://theeggandtherock.com/p/the-blowtorch-theory-a-new-model• Website: https://www.juliangough.com/Find Jack: • Spotify: https://open.spotify.com/show/0DGVMa1qAI1huc87xNDrgy?si=62c281d9e8274694• X: https://twitter.com/jack_roycroft• Substack: https://substack.com/@jackroycroftsherry?utm_campaign=profile&utm_medium=profile-page
