Physics to God

This episode discusses something many people fail to mention about the multiverse - that it actually makes a prediction. Well, sort of. You can probably guess that a theory about an infinite number of unobservable parallel universes can’t make a conventional prediction in the standard scientific sense. But with this “prediction”, you’ll see how multiverse scientists can avoid the three problems that plague a naive multiverse. While this episode is incredibly important for understanding the multiverse, it’s more complicated than the last one. But don’t worry - we have a marble analogy that makes everything crystal clear.

This is probably our favorite episode in the series. It was certainly the most fun to record. Together with the next four episodes, it contains the heart of our argument rejecting the multiverse and marks the conceptual turning point of this entire series. This episode in particular has a strange objective - to thoroughly reject a naive version of multiverse theory that no serious scientist actually believes in. While this may sound strange, this exercise is actually quite important. First of all, while no serious scientist accepts a naive multiverse, many popular presentations of the multiverse do. So it’s good to see the problems with the popular, but naive, version of multiverse. And more importantly, it turns out that understanding what a naive multiverse is, and where it goes wrong, is critical for appreciating the absolute necessity of multiverse’s third premise - that our universe is typical. But it should be clear that in this episode, we’ll be attacking a naive version of the multiverse. While the actual multiverse theory may seem absurd, many leading scientists believe that it’s a realistic possibility. The naive multiverse, on the other hand, is so completely ludicrous that no one serious can possibly believe it. At least we hope not...

Multiverse scientists use string theory to support the Varied Multiverse Premise. This episode will evaluate whether or not string theory truly supports the notion that the constants vary between universes. To do so, we’ll first need to give a little context on how string theory fits into the picture of modern physics and the pursuit of a final theory of everything (one theory that explains everything else in the universe). Then we’ll discuss some of the basic elements of string theory relevant to the multiverse.

Multiverse scientists support the claim that the constants vary by using fine tuning—yes, fine-tuning—the very same evidence we use for the existence of God. While it might sound strange that we come to the opposite conclusion based on the exact same evidence, this episode shows how it’s possible. Since multiverse scientists harbor a hidden premise their entire line of reasoning makes sense. But when this unjustified premise is dropped, it becomes clear that fine tuning points directly to the existence of God.

This episode discusses the Eternal Inflation Multiverse - the strongest support from modern physics for an infinite multiverse. This support comes from the theory of inflation and, in particular, from a model for this theory known as eternal inflation. By the time we’re done, you’ll have a basic idea of the theory of inflation and its various models, and see to what extent eternal inflation supports the infinite multiverse premise and doesn’t support the varied multiverse premise. And, you’ll learn a lot of fascinating physics along the way!

After an introductory discussion about the concept of infinity, this episode considers three lines of evidence that multiverse supporters bring to justify the Infinite Multiverse Premise.  Inductive reasoning; Empirical evidence; Many worlds interpretation of quantum mechanics.  Besides explaining these attempted supports, we’ll point out two problems with each of them. First, we’ll show how none of them convincingly demonstrates the existence of an infinite number of universes. More importantly, we’ll show that even though they may support an infinite number of universes, they don’t address, and sometimes even undermine, the Varied Multiverse Premise - the claim that the constants vary between universes.   TIMESTAMPS: 00:00 - Opening 2:13 - Actual Physical Infinity 6:18 - Functional Infinity 9:55 - Three Supports for the Infinite Multiverse Premise 11:24 - Inductive Reasoning 17:18 - Empirical Evidence 21:25 - Many Worlds Interpretation 26:17 - Many Worlds Multiverse 29:50 - Extending the Many Worlds Interpretation Get essay versions of all episodes in Season 1: Intelligent Cause and Season 2: Analyzing & Rejecting Multiverse Subscribe to Physics to God on YouTube, Apple Podcasts, Spotify, or wherever you listen to podcasts.

Season 2: Analyzing & Rejecting Multiverse This season will clarify the three essential elements of multiverse theory, analyze their various scientific supports, and ultimately show why the multiverse fails to be a good explanation for fine tuning, design, and order, even in scientists' own framework. Episode 1: The Three Premises of Multiverse This episode lays out the three premises any multiverse theory needs to explain fine tuning, design, and order in our universe without an intelligent cause. - The Infinite Multiverse Premise: There exists a multiverse composed of infinitely many universes.  - The Varied Multiverse Premise: In the multiverse, the constants vary from universe to universe. - The Typical Universe Premise: Of all the universes in the multiverse that contain intelligent observers, our universe is typical. Note: While Season 2 builds on Season 1: An Intelligent Cause, it can also be followed independently. Nevertheless, this episode begins by summarizing Season 1’s three arguments for the existence of God.

Many people are already familiar with various presentations of the fine-tuning argument in discussions about the existence of God. Standard forms of the argument are often lacking and leave much room for skepticism and debate. Critics often point to the limitations of existing forms, such as when fine-tuning is presented as an “argument from elimination” that fails to demonstrate that the list of possibilities is either fully eliminated or whether the list of possibilities is truly exhaustive. Likewise, the “probabilistic approach” is often beset by unconvincing and speculative probabilities. These can lead to unsatisfactory conclusions for those seeking a more definitive understanding of our universe’s precise constants and the implications of their existence. In this episode, Aaron and Elie offer a fresh perspective that is tailored to a more advanced audience that is already familiar with the conventional treatments of the fine-tuning argument, focusing on the intrinsic mystery of the constants and suggesting that fine-tuning is not the problem, but is rather the all-important clue to the solution of the mystery. They articulate why their approach avoids the pitfalls of other arguments, such as the God-of-the-gaps critique, and present fine-tuning as an answer to one of physics’ fundamental questions, establishing a robust case for an intelligently designed universe that is compelling even to an audience well-versed in the topic. This presentation, a bit more advanced and informal than other episodes of Physics to God, was made to a group of scholars from Reasons to Believe.

Three arguments for intelligent cause presented: fine tuning of constants, design of laws, and initial conditions at big bang. Addressing frequently asked questions. Need and motivation for next two series about God and multiverse.

In this episode, we complete our final argument and convincingly show that the low entropy initial conditions at the big bang point directly to an intelligent cause for the order in our universe - what we’ll call an intelligent orderer. In doing so, we’ll encounter an amazing, mind-bogglingly gargantuan number. Once we explain how massive this number actually is, you’ll see how massively unlikely it is that our universe emerged by chance alone.
