Before the Big Bang 1O : Black Hole Genesis

We interview the creators of 3 models of the early universe that imply the big bang came from a black hole in a mother universe. The models are Cosmological Natural Selection (CNS), The Holographic Big Bang and Cosmology with Spin and Torsion. The creators interviewed are Lee Smolin, Nikodem Poplawski and Niayesh Ashfordi. Recently it has also been shown that a theory of quantum gravity called Causal Set Theory may realise CNS. And so we also talk to Stav Zalel who has worked on this idea and cosmologist Aureliein Barau
