Transcript and Thoughts on My Debate with Justin Schieber

by Max Andrews

Over the last month or two I’ve been working on a written/audio debate with Justin Schieber of Reasonable Doubts. The topic of the debate was “Does the Christian God Exist?” I imagine the debate may have been released earlier had it not been for my delayed responses due to health issues and moving out of our house and preparing to embark on our move to Scotland. I have apologized to Mr. Schieber concerning this and I extend apologies to the readers and listeners.

I was actually expecting much stronger arguments from Mr. Schieber. Two arguments were off topic and the other one was a far metaphysical and modal stretch. You’ll be able to read his arguments in full but here are my thoughts :

Peter Atkins on the Origin of Everything: Much ado about Nothing

by Max Andrews

The Origin of Everything: Much Ado About Nothing” is a talk by physical chemist Peter Atkins on the boundaries between science and philosophy when it comes to examining the origins of the universe and nothingness.

Q&A 28: The Multiverse, Many Worlds, and the Problem of Evil

by Max Andrews

Question:

Hey Max,
This was a great idea to start this Q&A section!  I have a question regarding the Problem of Evil that I have been working on for a couple months now.  I haven’t yet found an intellectually satisfying answer, but hopefully through you, God will provide one.  (I almost didn’t want to ask it because I enjoy the “chase” as Christ reveals Himself to me through the process!)

MA Thesis Available Online — “The Fine-Tuning of Nomic Behavior in Multiverse Scenarios”

by Max Andrews

My Master’s thesis is now available for download.

Department: Philosophy

Degree: Master of Arts

Chair: W. David Beck

Primary Subject Area: Philosophy; Physics, Astronomy and Astrophysics; Religion, General; Physics, Theory; Physics, General

Keywords: cosmology, fine-tuning, information, multiverse, philosophy of science, quantum

Disciplines: Astrophysics and Astronomy | Cosmology, Relativity, and Gravity | Philosophy | Philosophy of Science | Quantum Physics | Religion

Abstract: The multiverse hypothesis (the view that there is not just one world or universe in existence, bur rather that there are many) is the leading alternative to the competing fine-tuning hypothesis (the laws of physics and constants are fine-tuned for the existence of life).

Exceptions to a Finite Universe

by Max Andrews

The Borde-Vilenkin-Guth Theorem states that any universe, which has, on average, a rate of expansion greater 0 that system had to have a finite beginning. This would apply in any multiverse scenario as well.  There are four exceptions to the theorem.*

1. First Exception: Initial Contraction (Havg<0) … (The average rate of the Hubble expansion is less than zero)

  • Main Problem: Another problem this raises is that this requires acausal fine-tuning.  Any attempt to explain the fine-tuning apart from a fine-tuner is left bereft of any explanation.

2. Second Exception: Asymptotically static (Havg=O)

  • Main Problem: The exception is that it does not allow for an expanding or evolutionary universe.  This model cannot be true.  The best evidence and empirical observations indicate that the universe is not static; rather, it is expanding and evolving.  This might have been a great model under Newton but not since Einstein’s field equation concerning the energy-momentum of the universe.

A List of Physical Constants and Their Values

by Max Andrews

Physical constants are the values of certain spacetime, energy, and natural laws that have a set parameter that determine the structure and function of a life-permitting universe. Constants will vary in value from universe to universe in multiverse scenarios. When I refer to ‘constants’ here I mean what we presently observe as being constant. For example, the value of gravity may vary from universe to universe. The following are this universe’s constants and their values.[1]

Constants of Space and Time.

  1. Planck length (the minimum interval of space), lp = 1.62 x 10-33 cm.
  2. Planck time (the minimum interval of time), tp = 5.39 x 10-44 sec.
  3. Planck’s constant (this determines the minimum unit of energy emission), h = 6.6 x 10-34 joule seconds.
  4. Velocity of light, c = 300,000 km/sec.

An Abductive Fine-Tuning Argument

by Max Andrews

The fine-tuning argument argues that when physics and the laws of nature are expressed mathematically their values are ever so balanced in a way that permits the existence of life. I’m merely arguing that the universe is finely tuned for the essential building blocks and environments that life requires.

  1. Given the fine-tuning evidence, a life permitting universe (LPU) is very, very unlikely under the non-existence of a fine-tuner (~FT): that is, P(LPU|~FT & k) ≪ 1.
  2. Given the fine-tuning evidence, LPU is not unlikely under FT (Fine-Tuner): that is, ~P(LPU|FT & k) ≪ 1.
  3. Therefore, LPU strongly supports FT over ~FT.[1]

Defense of 1: Given the fine-tuning evidence, a life-permitting universe is very, very unlikely under the non-existence of a fine-tuner.

So what are some of the evidences for fine-tuning?

  1. Roger Penrose calculates that the odds of the special low entropy condition having come about by chance in the absence of any constraining principles is at least as small as about one in 1010^123.[2]
  2. Strong Nuclear Force (Strong nuclear force coupling constant, gs = 15)
    1. +, No hydrogen, an essential element of life
    2. -, Only hydrogen

An Abductive Thomistic Cosmological Argument

by Max Andrews

The following argument is an abductive Thomistic cosmological argument from contingency, which I presented at my recent Ratio Christi debate.

  1. There are contingent constituents to the universe.
  2. Given the contingent constituents of the universe, the existence of the universe (U) is very, very unlikely under the hypothesis that these constituents are themselves uncaused or self-caused (~Cu): that is, P(U|~Cu & k) ≪ 1.
  3. Given the contingent constituents of the universe, the existence of the universe is not unlikely under the hypothesis of a first uncaused cause (Cu): that is, ~P(U|Cu & k) ≪ 1.
  4. Therefore, U strongly supports Cu over ~Cu.

The constituents of the universe include galaxies, planets, stars, cars, humans, leptons, bosons, and other particles. For the constituents of the universe to be uncaused that would mean it is metaphysically necessary. For something to be metaphysically necessary that means that it could not have failed to exist—it exists in every possible world.

For something to be self-caused it must be simultaneously antecedent to itself to produce itself as its own effect. But this contradictory. This would be akin to the ultimate bootstrapping trick.
