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.

A New Cosmological Argument: EPS 2014

by Max Andrews

This year’s Evangelical Philosophical Society Annual Conference will be in San Diego, California, USA (500 Hotel Circle North, San Diego, California 92108). I will be presenting from 0920 to 1000 on Wednesday in EPS Session A4 in Windsor.

This is the third year in a row I’ve had a paper accepted for presentation at EPS (coauthoring with Dave Beck). This paper will help thresh out some of my research concerning the behaviour of natural law as well as methodology in a philosophy of cosmology. In the paper I will be able to examine different cosmological models (primarily multiverse models) and consider the necessitarian vs. regularity debate as well as the metaphysical and modal status of natural law and the ontological furniture of all reality. This is relevant to several sections of my thesis and the peer feedback offered by conferences such as this are vital to have external minds critiquing my proposed models for many universes and, what I believe to be, the radical metaphysical contingency of worlds.

Philosophical Fragments Botches the Multiverse

by Max Andrews

Philosophical Fragments is a blog with Patheos and there was a guest post (don’t hold it against he actual blog owner, it’s a guest) named Mark Goldblatt (I’m not certain that’s the author but notice his employer and notice what he’s writing on… I’m just saying…) titled “Bad Epistemology.” Let me begin by telling you what I really think… I think this post is full of bad science, bad philosophy, bad semantics, quibbling over spilled milk, and botches the multiverse is an embarrassingly bad way. Aaaand, yes, there are some good things and I won’t forget to highlight them either.

If you want to argue against the multiverse [or quantum issues], fine, but do so in an informed and more educated manner than this.

Goldblatt begins his epic rant by discussing contemporary science’s search and desire to discover the truth about the cosmos and the origin of life. Quoting Neil deGrasse Tyson from the reinstatement of Cosmos:

“If you take the universe all the way back to the Big Bang, well, the entire universe was really small. So now you take the shotgun wedding – quantum physics and general relativity. In that shotgun wedding, if you follow through with all the predictions quantum physics gives you, it allows multiple bubbles to form – one of which is our universe. These are sorts of fluctuations in the quantum foam. Quantum physics fluctuates all the time. But now the fluctuations are not just particles coming into and out of existence, which happens all the time. It’s whole universes coming into and out of existence.”

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

by Max Andrews

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

by Max Andrews

our mathematical universe tegmarkI’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…

The Affirmations and Denials Directory

by Max Andrews

I’ve decided to make a referent post that outlines my position on many things philosophical, theological, scientific, biblical, and other. I have many similar directories: Molinism, Multiverse, Philosophy of Science, Epistemology, and the Origins Directory.

Ontological Basics

  1. Ontological Status. Existent
  2. Necessary. No
  3. Contingent. Yes
  4. Person. Yes
  5. Organic. Yes
  6. Faculty of Will. Incompatibilist (although all we need is that flicker of freedom).
  7. Personhood. Cartesian Substance Dualist, leaning Hasker’s emergentism.

Bible & Theology

  1. Theology. Theist
  2. Religion. Christian
  3. Trinity: Social Trinitarian
  4. Denomination. Associate Reformed Presbyterian (Don’t ask me how that happened…)
  5. Catholic. No. Some Catholic Dogma is contrary to what I understand the gospel to be. Some Catholics love Jesus and are saved as well, though in spite of the Catholic teaching.
  6. Eastern-Orthodoxy. No. See above.
  7. Middle Knolwedge. Yes
  8. Molinist. Yes.
  9. Soteriology. A Molinist Model

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 Philosophy of Cosmology Flirts with the Multiverse

by Max Andrews

ID the Future just put out a new podcast reviewing an interview from The Atlantic discussing the new field in the philosophy of physics–the philosophy of cosmology. The content is from last year but the content isn’t outdated.

On this episode of ID The Future, host David Boze reports on the latest views of a group of cosmologists who want to establish a new philosophy of cosmology to tackle the big questions of the universe. What happened after the Big Bang? Was there something before that to cause the existence of the universe? What are bubble universes?

A Theological Argument for Many Worlds

by Max Andrews

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.

Cosmic Darwinism: Evolving Laws of Nature?

by Max Andrews

The following are a few questions raised in light of Rupert Sheldrake’s The Science Delusion: Freeing The Spirit Of Enquiry. 

The argument that he advances in the chapter involves something he calls ‘habits’, which are “a kind of memory inherent in nature”. (From what I understand, he has also advanced this within a theory of ‘morphic resonance’ in his other published works.) Putting aside his case for these ‘habits’, three questions that he poses to materialists at the end of the chapter caught my eye:

1) If the laws of nature existed before the Big Bang, and governed the Big Bang from its first instant, where were they?

2) If the laws and constants of nature all came into being at the moment of the Big Bang, how does the universe remember them? Where are they ‘imprinted’?

3) How do you know that the laws of nature are fixed and not evolutionary?
