Podcast: What Kinds of Multiverses are There?

by Max Andrews

Podcast: https://soundcloud.com/sententias/eavesdropping-ep25-levels-of-the-multiverse

Contemporary physics seem to indicate that there are good reasons, theoretically and physically, for an idea that there is a plurality of worlds. This concept has come to be understood as the multiverse. The multiverse is not monolithic but it is modeled after the contemporary understanding of an inflationary model of the beginning of this universe. Max Tegmark has championed the most prominent versions of the multiverse. Tegmark has made a four-way distinction.

Would Multiple Universes Rule Out Fine-Tuning?

by Max Andrews

The multiverse hypothesis is the leading alternative to the competing fine-tuning hypothesis.  The multiverse dispels many aspects of the fine-tuning argument by suggesting that there are different initial conditions in each universe, varying constants of physics, and the laws of nature lose their known arbitrary values; thus, making the previous single-universe argument from fine-tuning incredibly weak.  There are four options for why a fine-tuning is either unnecessary to invoke or illusory if the multiverse hypothesis is used as an alternative explanans. Fine-tuning might be (1) illusory if life could adapt to very different conditions or if values of constants could compensate each other. Additionally, (2) it might be a result of chance or (3) it might be nonexistent because nature could not have been otherwise.  With hopes of discovering a fundamental theory of everything all states of affairs in nature may perhaps be tautologous.  Finally, (4) it may be a product of cosmic Darwinism, or cosmic natural selection, making the measured values quite likely within a multiverse of many different values. In this paper I contend that multiverse scenarios are insufficient in accounting for the fine-tuning of the laws of nature and that physicists and cosmologists must either accept it as a metaphysical brute fact or seriously entertain the hypothesis of a fine-tuner.

I.  Outlining the Multiverse Hierarchy

Contemporary physics seem to indicate that there are good reasons, theoretically and physically, for the postulation a plurality of worlds.  This concept has come to be understood as the multiverse.  The multiverse is not monolithic, but it is modeled after the contemporary understanding of an inflationary model of the beginning of this universe.  Max Tegmark has championed the field of precision cosmology and has proposed the most prominent versions of the multiverse.[1]  Tegmark has made a four-way distinction in classifying these models.

The Quantum Universe and the Universal Wave Function

by Max Andrews

In 1956 Hugh Everett III published his Ph.D. dissertation titled “The Theory of the Universal Wave Function.”  In this paper Everett argued for the relative state formulation of quantum theory and a quantum philosophy, which denied wave collapse.  Initially, this interpretation was highly criticized by the physics community and when Everett visited Niels Bohr in Copenhagen in 1959 Bohr was unimpressed with Everett’s most recent development (439).  In 1957 Everett coined his theory as the Many Worlds Interpretation (MWI) of quantum mechanics.  In an attempt to circumvent the problem of defining the mechanism for the state of collapse Everett suggested that all orthogonal relative states are equally valid ontologically. An orthogonal state is one that is mutually exclusive.  A system cannot be in two orthogonal states at the same time.  As a result of the measurement interaction, the states of the observer have evolved into exclusive states precisely linked to the results of the measurement.  At the end of the measurement process the state of the observer is the sum of eigenstate—or a combination of the sums of eigenstates, one sum for each possible value of the eigenvalue.  Each sum is the relative state of the observer given the value of the eigenvalue (442-43).  What this means is that all-possible states are true and exist simultaneously.

“God and the Multiverse” EPS 2012 Paper

by Max Andrews

David Beck and I recently presented a paper on God and the multiverse at the annual Evangelical Philosophical Society conference in Milwaukee, WI on November 14, 2012. In this paper we argue that if a multiverse exists then it is harmonious with theism. Not only do we argue that it’s compatible with theism but we develop a distinctly Christian approach to it. We trace the idea of many worlds back to the pre-Socratics, which contributed to a theistic framework. We use Thomas Aquinas, Leibniz, Kant, Clement of Alexandria, Origen, and others to create a Christian model of modal realism. We have called our model “Thomistic Modal Realism.” We plan on explicating the paper and submitting it for publication soon. Please feel free to comment and leave feedback in the comment section. Any and all appropriate/substantive feedback will help us strengthen our model.

Karl Popper on the Many Worlds Interpretation

by Max Andrews

In a brief section of Karl Popper’s Quantum Theory and the Schism in Physics[1] he discusses his attraction to the Many Worlds Interpretation of quantum physics as well as the reason for his rejection of it. Popper is actually quite pleased with Everett’s three-fold contribution to the field of quantum physics. Despite his attraction to the interpretation he rejects it based on the falsifiability of the symmetry behind the Schrödinger equation.

Popper’s model allows for a theory to be scientific prior to supported evidence.  There is no positive case for purporting a theory under his model. There can only be a negative case to falsify it and as long as it may be potentially falsified it is scientific.  Thus, a scientific theory could have no evidence or substantiated facts to provide good reasons for why it may be true. What makes this discussion of MWI interesting is that despite Popper’s attraction to MWI it’s not the attraction that makes it scientific, it’s his criterion of falsification.

In favor of MWI:

  1. The MWI is completely objective in its discussion of quantum mechanics.
  2. Everett removes the need and occasion to distinguish between ‘classical’ physical systems, like the measurement apparatus, and quantum mechanical systems, like elementary particles.  All systems are quantum (including the universe as a whole).
  3. Everett shows that the collapse of the state vector, something originally thought to be outside of Schrödinger’s theory, can be shown to arise within the universal [Schrödinger] wave function.

We have a problem of using secondary sources. I’ve provided a link below that takes you back to Everett’s original dissertation to read for ourselves.
