## Identity in Branching Worlds (Multiverse)

In a non-Everettian context (Hugh Everett) identity may be understood in different ways. Consider David Wallace’s example of the ancient pot (P2). An antiquities specialist informs you that your P2 is the same as P1, a famous pot owned by Emperor Tiberius in ad 30. There is a four-dimensional tube P in spacetime extending from P1 toP2—a spacetime worm. The matter of the tube has certain structural and dynamical connections running along it. If we write P(t) for the contents of P indexed at time t, the specialist’s claim is underwritten by the existence of some structural-dynamical relation R holding, for each t, between P(t) and P(t + δt), with δ signifying a difference or change in time. Each indexed moment along P(t) would simply be a stage of the pot’s existence.

There are two basic philosophical conclusions about the identity of the pot being the same pot. The first is called the Worm View as I’ve previously alluded to. Under this view, P is the pot and P1 and P2 are just different names for the pot (literally, P1 = P2). The second view that the P1 and P2 are the same is the Stage View. The pot appears as an instantaneous three-dimensional object: P1 = P(AD 30); P2 = P(AD 2016). Thus, to say that P1 and P2 is the same pot, it means: P2 is linked to P1 by a continuous chain of R-related pots.

## What is a Scientific Explanation?

Scientific Explanation

• If scientific explanation is causal explanation, and causation is law-governed sequence, then it follows that scientific explanations require laws.  However, a problem with this (i.e. the ideal gas law: PV=nRT) is that instead of making things clearer, it threatens to involve the analysis of scientific explanation in a thicket of “metaphysical” issues that several philosophers and positivists sought to avoid.[1] Scientific explanation requires a causal explanation, which requires a law-governed explanation.
• Natural law describes but does not explain natural phenomena.
• Consider the use of D-N: Newton’s law of universal gravitation described, but did not explain, what caused gravitational attraction.  Newton claimed that he invented no hypotheses but deduced them from observations produced by rationalistic positivism, which engulfed contemporary European science.  Even though Newton’s law does not explainthe data, it is still scientific but offers no scientific explanation.  Many scientific theories do not offer an explanation by natural law.  Instead, they postulate past regularities to explain presently observed phenomena, which also, in turn, allow for predictive capabilities
• Our knowledge of cause and effect relationships, which can sometimes formulate as laws, will often guide the inferences that scientists make about what happened in the past and will influence their assessment of the plausibility of competing explanations.

## Molinism Book on Sale for a Reduced Price

My newest eBook, book 2 in the series of Molinism eBooks, The Spread of Molinism, is now on sale at a reduced price for $5.99 (Normal listed price is$8.99). The sale will only be available for a week and will end on Valentine’s Day!

I’m very grateful to Ken Keathley, author of Salvation and Sovereignty: A Molinist Approach, for his contribution and foreword to the eBook.

The aim of my first eBook on Molinism, An Introduction to Molinism: Scripture, Reason, and all that God has Ordered, was intended to ease in those who may be unfamiliar with the major talking points and issues concerning Molinism today. Likewise, it was intended to present Molinism accurately, avoiding misrepresentations or straw-men presentations from non-Molinists.

## Eavesdropping Ep12: The Quantum Scale

In Eavesdropping Ep12 I discuss the range of values on the quantum scale for length, speed, and time. I use a few illustrations to help provide a perspective for how big and how small our physical reality is.

Eavesdropping is conversational, informal podcast that is sometimes a monologue, or dialogue with guests, on various topics including philosophy, theology, science, contemporary events, and random meanderings of a philosopher. The primary focuses are philosophy of science, multiverse scenarios, and Molinism.

## Discovery of quantum vibrations in ‘microtubules’ inside brain neurons supports controversial theory of consciousness

The pre-Socratics have a habit of coming back to the moderns and contemporaries and saying, “I told you so.” This is something Dave Beck and I argue in regards to the multiverse (or many worlds) in a forthcoming paper in Philosophia Christi this summer. Could it be the case that Democritus was right about mind being in the finer atoms?

SourceScience Daily

Summary: A review and update of a controversial 20-year-old theory of consciousness claims that consciousness derives from deeper level, finer scale activities inside brain neurons. The recent discovery of quantum vibrations in “microtubules” inside brain neurons corroborates this theory, according to review authors. They suggest that EEG rhythms (brain waves) also derive from deeper level microtubule vibrations, and that from a practical standpoint, treating brain microtubule vibrations could benefit a host of mental, neurological, and cognitive conditions.

## Q&A 38: The Infinite Set of You in the Multiverse

Question

Dear Mr. Andrews,

I came upon your blog and I shall spend the better part of the night reading it, and I have a few questions about the multiverse that I don’t understand.

First off, why is it inevitable that some parallel universes would be identical to this one? Why would there be another me, identical down to each thought, instead of endlessly unique ones? That is to say, why would there be an infinite number of universes but only a finite variety of patterns?

Also, would endlessly different ones render the fantastic real? Unicorns and Greek gods roaming universes of their own?

Or have I missed what MWI supporters are trying to say?

Also, if the multiverse allows for at least a few super civilizations to exist, so powerful that they can create their own universes or cross others, then wouldn’t they essentially function as gods, albeit not our eternal one?

Thank you so much, and Happy New Year!

Sincerely,

Katy Meyrick

## Max Tegmark and The Fluke Explanation for Life

I’m reading Max Tegmark’s newest and only book Our Mathematical Universe, which I will be reviewing for an academic journal. I wanted to share, as much as I could without copyright infringement an amazing point on the issues of fine-tuning in the most broad sense of the word (the existence of a universe that permits the existence of life).

So what are we to make of this fine-tuning? First of all, why can’t we just dismiss it all as a bunch of fluke coincidences? Because the scientific method doesn’t tolerate unexplained coincidences saying, “My theory requires an unexplained coincidence to agree with observation.” For Example, we’ve seen how inflation predicts that space is flat and the spots in the cosmic microwave background should have an average size around a degree, and that the experiments…. confirmed this… Suppose the Planck team observed [something else being] much smaller average spy size, prompting them to announce that they’d ruled out inflation with 99.999% confidence. This would mean that random fluctuations in a flat universe could [author’s emphasis] have caused spots to appear as unusually small as they measured, tricking them into an incorrect conclusion, but what with 99.999% probability this wouldn’t happen? In other words, inflation  would require a 1 – in – 100,000 unexplained coincidence in order to agree with the measurement…

## A Theological Argument for Many Worlds

The following is the abstract to Don Page’s paper, “A Theological Argument for an Everett Multiverse.”

Science looks for the simplest hypotheses to explain observations. Starting with the simple assumption that {\em the actual world is the best possible world}, I sketch an {\it Optimal Argument for the Existence of God}, that the sufferings in our universe would not be consistent with its being alone the best possible world, but the total world could be the best possible if it includes an omnipotent, omniscient, omnibenevolent God who experiences great value in creating and knowing a universe with great mathematical elegance, even though such a universe has suffering.

## Boltzmann Brains and Multiverse Scenarios

Max Tegmark has introduced an anthropic principle specifically related to multiverse scenarios—the minimalistic anthropic principle (MAP). Tegmark believes the anthropic principle has generated more heat than light with so many different interpretations. MAP states that when testing fundamental theories with observational data, ignoring selection effects can give incorrect conclusions.[1]

Tegmark does not use MAP and selection effects to rule out everything. It cannot rule out chaotic inflation by the fact that we find ourselves living in the miniscule fraction of space where inflation has ended, since the inflating part is uninhabitable to us. As pointed out by Ludwig Boltzmann, if the universe were in a classical thermal equilibrium (heat death), thermal fluctuations could still make atoms assemble at random to briefly create a self-aware observer (a Boltzmann brain) like us every once in a blue moon, so the fact that we exist right now does not rule out the heat death cosmological model.[2]  So, what should we do with Boltzmann brains?
