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 The order of subjects is LS: Lee Smolin NA: Niayesh Ashfordi SZ: Stav Zalel NP: Nikodem Poplowski AB: Aurelien Barau 00:00 Introduction 51:55 LS and SZ on CNS 3:53 the prehistory of CNS 6:08 NA doubt on fine tuning 7:33 NA on The Holographic Big Bang 10:32 NA explains The Holographic Principle 13:41 NP on Cosmology with Spin and Torsion 16:16 NP on anti matter 17:44 SZ on quantum gravity 18:21 LS and NP on the big bounce 20:23 SZ and AB on Causal Set Theory 21:32 SZ on comparison with Loop Quantum Gravity 21:47 AB and SZ on predicting the cosmological constant 23:24 SZ on linking CNS and Causal Set Theory 24:53 NA on string theory connection 25:46 LS on neutron star predictions 30:15 LS on inflation and CNS 31:08 NP on inflation and torsion 33:08 NA on replacing inflation 35:25 LS on CNS versus eternal inflation 36:55 NA on the difference between CNS and The Holographic Big Bang 37:14 LS, NP and NA on entropy 38:40 LS and NA on Roger Penrose’s criticism 40:47 LS, NP, SZ and NA on an eternal past 43:49 LS on answering Leonard Susskind 44:39 LS on scare resources 45:08 NA on CMB predictions 46:06 LS summing up
