This episode can be seen as a stand-alone summary of our analysis and rejection of the multiverse, or as a review of the main points of this season. It’s perfect for anyone interested in understanding why the multiverse fails but doesn’t have the stamina to listen to the whole season. You can find a written version of the episode here. We also just released the first episode of the complete Season 2 about Multiverse on our @PhysicsToGod YouTube channel. Some points we discuss in this episode include: The Fine Tuning Argument, Three Premises of Multiverse, Many Worlds Interpretation of Quantum Mechanics, Eternal Inflation, String Theory, Naive Multiverse, Is Our Grand Universe Typical?, Infinities and Measures, The Boltzmann Brain Problem, The Three Layers of the Measure Problem, Is the Multiverse Science?

This episode examines physicist Roger Penrose's extremely wild and imaginative theory for explaining the ridiculously improbable order of the Big Bang without invoking an intelligent cause. Penrose describes the tremendous problem of explaining the unlikely Big Bang as follows: In order to produce a universe resembling the one in which we live, the Creator would have to aim for an absurdly tiny volume of the phase space of possible universes – about 1/10^10^123 of the entire volume...This is an extraordinary figure. One could not possibly even write the number down in full... When Penrose speaks about the Creator, he means it metaphorically, as he doesn’t believe in God. This episode shows how Penrose’s theory - Conformal Cyclic Cosmology - attempts to explain the improbable order of the Big Bang without an intelligent Creator, and ultimately justifies why we think the argument for an intelligent cause still stands.

Cyclic Universes and Bouncing Cosmology - S2:E15
Our universe’s initial state was incredibly unlikely, and if it were even slightly different, nothing would exist except for black holes. This episode discusses physicist Paul Steinhardt’s theory of Bouncing Cosmology which attempts to explain this unlikely beginning without requiring either an infinite varied multiverse or an intelligent cause. This theory is so wild and imaginative that we really had to struggle to come up with analogies to make it understandable to everyone. But we did. And these might just be our best analogies yet.

Cosmological Natural Selection - S2:E14
Biologist Richard Dawkins, in his book, The Blind Watchmaker, wrote the following: The theory of evolution by cumulative natural selection is the only theory we know of that is, in principle, capable of explaining the existence of organized complexity. Even if the evidence did not favour it, it would still be the best theory available. In this episode, we discuss physicist Lee Smolin’s attempt to extend natural selection from biology and apply it to the cosmos as a whole in order to explain fine tuning in physics. We start by discussing black holes and baby universes and end with what Smolin calls the meta-laws dilemma.

Is Multiverse Science? - S2:E13
Multiverse scientists deviate from the longstanding scientific method, grounded in predictions and observations, by positing infinitely many unobservable parallel universes to explain fine tuning. They have subtly switched to a mathematically formulated philosophical theory about an infinite multiverse to explain the fine tuning of our one ordered universe. This episode justifies why the multiverse is not science, and supports this assertion through the words of prominent scientists who attempt to defend the esteem of science from the multiverse’s corrosive effects.

Physics to God is a guided journey through modern physics to discover God. We start from the fine tuning of the constants of nature, travel through the multiverse, and ultimately arrive at a compelling idea of God.
