Robin Collins lectures on fine-tuning for discoverability from particle physics

Christianity and the progress of science
Christianity and the progress of science

Here’s the lecture:

This lecture is 29 minutes long, the Q&A is 15 minutes. I highly recommend this lecture to all audiences of all levels of ability, for the simple reasons that apart from the content, this lecture is a how-to clinic in the tone, body language, slides and so on for you to use when trying to be persuasive when making your case. Science is king in this lecture. The scientific method is defined and applied in a winsome way. Making science understandable should be the bread and butter approach to Christian apologetics, and this lecture rivals the Mike Strauss lecture at Stanford University and the Mike Strauss lecture at the University of Texas – Dallas as the ideal lectures for showing that. It’s not just the scientific material that makes this lecture by Collins work, it’s the narrative and the style that make the lecture work.

About Robin Collins:

Robin Collins (PhD, University of Notre Dame, 1993), is professor of philosophy at Messiah College, Grantham, PA specializing in the area of science and religion.  He has written over twenty-five articles and book chapters on a wide range of topics, such as the fine-tuning of the cosmos as evidence for the existence of God, evolution and original sin, the Doctrine of Atonement, Asian religions and Christianity, and Bohm’s theory of quantum mechanics.  Some of his most recent articles/book chapters are “Philosophy of Science and Religion” in The Oxford Handbook of Science and Religion, “Divine Action and Evolution” in The Oxford Handbook of Philosophical Theology (2009)  “The Multiverse Hypothesis: A Theistic Perspective,” in Universe or Multiverse? (Cambridge University Press), and “God and the Laws of Nature,” in Theism or Naturalism: New Philosophical Perspectives (Oxford University Press, forthcoming).  He recently received a grant from the John Templeton Foundation to finish a book that presents the case for design based on physics and cosmology,  tentatively entitled The Well-Tempered Universe: God, Cosmic Fine-tuning, and the Laws of Nature.

His thesis in one slide:

Fine-tuning for discoverability
Fine-tuning for discoverability – the DLO thesis

Summary:

  • Thesis: the universe is more intelligible than we would expect it by chance
  • The regular fine-tuning argument says that complex embodied observers are very rare
  • But the number of highly-discoverable universes that have complex embodied observers is rarer still
  • Why do we exist in a highly-discoverable universe?
  • Can we quantify and test discoverability?
  • Yes: by varying fundamental parameters and seeing how it affects discoverability
  • Conclusion of his calculations: The Discoverability-Liveability Optimality range is an even smaller range within the Liveablity Optimality range of the standard fine-tuning argument
  • Fine-tuning #1: the fine structure constant, governs the strength of the electro-magnetic force
  • If larger, wood-burning fire becomes impossible because fires won’t stay lit, and therefore forging metals becomes unlikely
  • If smaller, wood-burning fires won’t go out, e.g. – from lightning strikes, so that wood would be less accessible
  • Other constraints: smaller value decreases effectiveness of light microscopes, drastically lowers efficiency of transformers and motors
  • Fine-tuning #2: the cosmic microwave background radiation (CMBR), radiation left over from the Big Bang
  • humans need to discover the CMBR in order to confirm the Big Bang creation out of nothing, and it depends on baryon/pothon ratio
  • his calculations show that the actual value of CMBR is exactly at the peak for detectability by humans
  • if baryon/photon ratio larger, CMBR is less discoverable
  • if baryon/photon ratio smaller, CMBR is less discoverable
  • Fine-tuning #3: parameters related to subatomic particles are fine-tuned for their discovery and usefulness, e.g. – the bottom quark, the charm quark, the tau lepton and the Higgs Boson
  • the lifetime of the particles affects their usefulness to scientists who want to investigate the Standard Model of physics
  • decay rates of these subatomic particles are related to several of the finely-tuned parameters
  • for example, the mass of the bottom quark is finely-tuned for its discoverability by scientists
  • the tau lepton and the charm quark are similarly fine-tuned for disoverability
  • the mass of the Higgs boson is finely-tuned for discoverability and for making further discoveries
  • Conclusion: the DLO thesis is strongly confirmed – this is an even greater degree of fine-tuning that the already astonishing probabilities of the fine-tuning for complex, embodied intelligent beings
  • The formalized version of the philosophical argument based on this evidence is impervious with some of the traditional objections to the standard fine-tuning argument
  • #1 multiverse/selection effect: it is not subject to multiverse / observer selection objections
  • #2 normalizeability: it is not subject to the McGrew-Vestrup objection because the range of possible values is finite not infinite
  • #3 falsifiability: it makes falsifiable predictions, and in fact Collins’ earlier calculations of the CMBR discoverability contained an error that falsified the thesis – until he found the error and corrected for it
  • #4 usefulness: it gives clues about the Creator’s purpose for us, namely that the universe was created for us to be able to do science and find evidence of the Creator’s existence – there is no expectation for us to exercise blind faith, trust in God is meant to be a plausible deduction from the progress of experimental science

Earlier, I blogged about a Robin Collins lecture on the fine-tuning that allows complex, embodied life to exist. Another must-see lecture. If you are looking for something to study in university, and you have funding, then physics, mathematics and philosophy are the best places to be for a Christian scholar.

How do atheists try to accommodate the Big Bang in their worldview?

J. Warner Wallace: God's Crime Scene
J. Warner Wallace: God’s Crime Scene

OK, so J. Warner Wallace has a new book out and it’s about science and God.

I wanted to link to something about Lawrence Krauss trying to accommodate the Big Bang within his worldview of atheism.

Wallace writes:

One of the key pieces of evidence in the universe is simply it’s origin. If our universe began to exist, what could have caused it’s beginning? How did everything (all space, time and matter) come into existence from nothing? One way atheist physicists have navigated this dilemma has simply been to redefine the terms they have been using. What do we mean when we say “everything” or “nothing”? At first these two terms might seem rather self-explanatory, but it’s important for us to take the time to define the words. As I’ve already stated, by “everything” we mean all space, time and matter. That’s right, space is “something”; empty space is part of “everything” not part of “nothing”. For some of us, that’s an interesting concept that might be hard to grasp, but it’s an important distinction that must be understood. When we say “nothing”, we mean the complete absence of everything; the thorough non-existence of anything at all (including all space time and matter). These two terms, when defined in this way, are consistent with the principles of the Standard Cosmological Model, but demonstrate the dilemma. If everything came from nothing, what caused this to occur? What is the non-spatial, atemporal, immaterial, uncaused, first cause of the universe? A cause of this sort sounds a lot like a supernatural Being, and that’s why I think many naturalists have begun to redefine the terms.

Lawrence Krauss, Arizona State University Professor (School of Earth and Space Exploration and Director of the Origins Initiative) wrote a book entitled, “A Universe from Nothing: Why There Is Something Rather than Nothing”. As part of the promotion for the book, Krauss appeared on the Colbert Report where he was interviewed by comedian Stephen Colbert. During the interview, Krauss tried to redefine “nothing” to avoid the need for a supernatural first cause:

“Physics has changed what we mean by nothing… Empty space is a boiling, bubbling brew of virtual particles popping in and out of existence… if you wait long enough, that kind of nothing will always produce particles.” (Colbert Nation, June 21st, 2012)

Now if you’re not careful, you might miss Krauss’ subtle redefinition. In describing the sudden appearance of matter (“particles”), Krauss assumes the prior existence of space (“empty space”) and time (“if you wait long enough”). If you’ve got some empty space and wait long enough, matter appears. For Krauss, the “nothing” from which the universe comes includes two common features of “everything” (space and time), and something more (virtual particles). This leaves us with the real question: “Where did the space, time and virtual particles come from (given all our evidence points to their origination at the beginning of our universe)?” Krauss avoids this inquiry by moving space and time from the category of “something” to the category of “nothing”.

If you’ve got a teenager in your house, you might recognize Krauss’ approach to language. I bet you’ve seen your teenager open the refrigerator door, gaze at all the nutritious fruits and vegetables on the shelves, then lament that there is “nothing to eat.”

I used to say that when I was a teenager, but I grew out of it. I didn’t go on the Comedy Channel and try to convince everyone that what I was saying about the refrigerator was scientifically accurate.

Anyway, here is a debate between William Lane Craig and Lawrence Krauss, if you want to see how Krauss defends his “refrigerator has nothing to eat” view of cosmology. I know everybody and even many Christians all think that we have something to hide when it comes to science, but if you would just watch these debates, you would see that there is nothing to fear from science at all. We own it.

Meanwhile, I want to show you that this is not at all rare among atheists.

Look, here is Peter Atkins explaining how he makes the Big Bang reconcile with his atheism – and notice that it’s a completely different view than Krauss:

So, just who is this Peter Atkins, and why is he a good spokesman for atheism?

From his Wikipedia bio.

Peter William Atkins (born August 10, 1940) is an English chemist and a fellow and professor of chemistry at Lincoln College of the University of Oxford. He is a prolific writer of popular chemistry textbooks, including Physical Chemistry, 8th ed. (with Julio de Paula of Haverford College), Inorganic Chemistry, and Molecular Quantum Mechanics, 4th ed. Atkins is also the author of a number of science books for the general public, including Atkins’ Molecules and Galileo’s Finger: The Ten Great Ideas of Science.

[…]Atkins is a well-known atheist and supporter of many of Richard Dawkins’ ideas. He has written and spoken on issues of humanism, atheism, and what he sees as the incompatibility between science and religion. According to Atkins, whereas religion scorns the power of human comprehension, science respects it.

[…]He was the first Senior Member for the Oxford Secular Society and an Honorary Associate of the National Secular Society. He is also a member of the Advisory Board of The Reason Project, a US-based charitable foundation devoted to spreading scientific knowledge and secular values in society. The organisation is led by fellow atheist and author Sam Harris.

Now watch that 6-minute video above. Peter Atkins thinks that nothing exists. He thinks he doesn’t exist. He thinks that you don’t exist. This is how atheism adapts to a world where the Big Bang creation event is fact.

I think Peter Atkins should join Lawrence Krauss on the Comedy Channel and present that view. I would laugh. Wouldn’t you?

A Harvard University student explains how evidence changed her mind about God

Harvard University student discovers apologetics
Harvard University student discovers apologetics

Here’s a must-read article  about the effectiveness of apologetics on college campuses in Christianity Today.

Excerpt:

I don’t know when I first became a skeptic. It must have been around age 4, when my mother found me arguing with another child at a birthday party: “But how do you know what the Bible says is true?” By age 11, my atheism was so widely known in my middle school that a Christian boy threatened to come to my house and “shoot all the atheists.” My Christian friends in high school avoided talking to me about religion because they anticipated that I would tear down their poorly constructed arguments. And I did.

As I set off in 2008 to begin my freshman year studying government at Harvard (whose motto is Veritas, “Truth”), I could never have expected the change that awaited me.

It was a brisk November when I met John Joseph Porter. Our conversations initially revolved around conservative politics, but soon gravitated toward religion. He wrote an essay for the Ichthus, Harvard’s Christian journal, defending God’s existence. I critiqued it. On campus, we’d argue into the wee hours; when apart, we’d take our arguments to e-mail. Never before had I met a Christian who could respond to my most basic philosophical questions: How does one understand the Bible’s contradictions? Could an omnipotent God make a stone he could not lift? What about the Euthyphro dilemma: Is something good because God declared it so, or does God merely identify the good? To someone like me, with no Christian background, resorting to an answer like “It takes faith” could only be intellectual cowardice. Joseph didn’t do that.

And he did something else: He prodded me on how inconsistent I was as an atheist who nonetheless believed in right and wrong as objective, universal categories. Defenseless, I decided to take a seminar on meta-ethics. After all, atheists had been developing ethical systems for 200-some years. In what I now see as providential, my atheist professor assigned a paper by C. S. Lewis that resolved the Euthyphro dilemma, declaring, “God is not merely good, but goodness; goodness is not merely divine, but God.”

Joseph also pushed me on the origins of the universe. I had always believed in the Big Bang. But I was blissfully unaware that the man who first proposed it, Georges Lemaître, was a Catholic priest. And I’d happily ignored the rabbit trail of a problem of what caused the Big Bang, and what caused that cause, and so on.

By Valentine’s Day, I began to believe in God. There was no intellectual shame in being a deist, after all, as I joined the respectable ranks of Thomas Jefferson and other Founding Fathers.

I wouldn’t stay a deist for long. A Catholic friend gave me J. Budziszewski’s book Ask Me Anything, which included the Christian teaching that “love is a commitment of the will to the true good of the other person.” This theme—of love as sacrifice for true good—struck me. The Cross no longer seemed a grotesque symbol of divine sadism, but a remarkable act of love. And Christianity began to look less strangely mythical and more cosmically beautiful.

Now, I’m going to get into a lot of trouble for saying this, but I think that if you are a Christian and you are in a secular university, then you really need to have put in the effort to study the areas of science, history and philosophy that are relevant to the Christian faith. This is regardless of your personal abilities or field of study. We must all make an effort regardless of how comfortable we are with things that are hard for us to learn.

Granted, most people today are not interested in truth, because we just have this cultural preoccupation with having fun and feeling good and doing whatever we want to do whenever we want to do it. Most atheists I’ve met are like that, but some are more honest, open-minded, and they just have never encountered any good reasons or evidence to think that God exists and that Jesus is anything other than a man. There are a lot of atheists like that who are just waiting to hear some decent evidence. Our job is to prepare for them and then engage them, if they are willing to be engaged.

I think that definition of love she cited – self-sacrifice for the true good of another person – is important. I don’t think that ordinary Christians like you or me spends time on apologetics because we “like” it. I know lots of Christians who are in tough, expensive academic programs trying to get the skills they need to defend truth in areas that matter. They do this because they know that there are people out there who are interested in truth, and who are willing to re-prioritize their lives if the truth is made clear to them. We need to be willing to serve God by doing hard things that work.
