Almighty and everlasting God, you made the universe with all its marvelous order, its atoms, worlds, and galaxies, and the infinite complexity of living creatures: Grant that, as we probe the mysteries of your creation, we may come to know you more truly, and more surely fulfill our role in your eternal purpose; in the name of Jesus Christ our Lord.

IntroductionGoals

n To appreciate more fully the extent and wonder of God’s creation.

n To show how discoveries in modern astronomy and cosmology are:n compatible with a belief in a creator God,n can be most rationally explained by a creator God who deliberately

created a universe — or multiverse — that would be fruitful of life. ¡

IntroductionWhy God and the Multiverse?

n Romans 1:20 (NRSV): “Ever since the creation of the world his eternal power and divine nature, invisible though they are, have been understood and seen through the things he has made.”

n (Psalm 19: 1-4 NIV) : The heavens declare the glory of God; the skies proclaim the work of his hands.

n Day after day they pour forth speech; night after night they reveal knowledge.

n They have no speech, they use no words; no sound is heard from them.

n Yet their voice goes out into all the earth, their words to the ends of the world.

IntroductionWeek 1: A Universe with a Beginning

n Observational cosmology has firmly established, from multiple lines of evidence, that our universe began 13.8 billion year ago in an event called “The Big Bang.”n The past is finite; there is

a past limit to physical reality. ¡

IntroductionWeek 1: A Universe with a Beginning

n Cosmology’s discovery that the universe had a beginning empowers the traditional Cosmological Argument for the existence of God (The “second way” of St. Thomas Aquinas, 1224-1274, based on the idea of causation):n 1. Everything we see in this world is caused.n 2. Nothing can be the cause of itself.n 3. There cannot be an infinite regress of causes – because

the universe has a beginning. The past is finite.Therefore:n 4. There must exist an uncaused first cause not of this worldn 5. The word God means “uncaused first cause not of this

world”.n 6. Therefore, God exists. ¡

St. Thomas Aquinas

IntroductionWeek 2: A Universe Finely Tuned for Life

n The “Teleological Argument” for the existence of God: the world looks like it was deliberately designed for a purpose.

n Formally (after William Paley):n 1. Human artifacts (for example, a watch) are products of

intelligent design.n 2. The orderliness and intricacy of the universe resembles these

human artifacts.n 3. Therefore: the universe is likely a product of intelligent

design.n 4. But the universe is vastly more complex and gigantic than a

human artifact.n 5. Therefore: there probably is a powerful and vastly intelligent

designer who designed the universe (= God). ¡William Paley (1743-1805)

IntroductionWeek 2: A Universe Finely Tuned for Life

n Results from modern physics and cosmology empower the Teleological Argument for the God’s existence, for the physical laws of universe seemed incredibly “fine tuned” or “adjusted” for the purpose of giving rise to life (= the so-called “anthropic coincidences”). We sampled some of these last week:n 1. Masses of the fundamental particles,n 2. Relative strengths of the electromagnetic

and strong forces,n 3. The Triple Alpha process to produce

carbon from helium. ¡

Only up quark, down quark, and electron masses in the area of the small green wedge allows for complex chemistry, and hence the possibility of life. Our universe fortuitously lies at the position of the white dot.

IntroductionWeek 2: A Universe Finely Tuned for Life

n The alternative explanation to a powerful and vastly intelligent designer for such apparent “fine-tuning” is that there is an unimaginably enormous array of universes (= a Multiverse) that have laws of physics with random parameters, nearly all these universes dead and sterile, and we just happen to live in one where all the parameters, by random chance, are “just right” for life.

n This explanation is less satisfying given:n Ockham’s razor: unnecessary, excessive material should

be cut away from any explanation, and the simplesthypothesis accepted,

n The “meta-laws” of a Multiverse themselves need to be finely tuned to avoid Boltzmann Brains. ¡

IntroductionThis Week: An Orderly, Rational,

Comprehensible, Beautiful Universen This week we will look at some additional questions, questions science

is unlikely to ever be able to answer or explain:n Where do the laws of physics come from? [or, if there is a Multiverse] Where

do the “meta-laws” of the Multiverse come from?n Why is there any order at all, why not just chaos?

n Why should the laws of physics that lead to a universe fruitful of life and of conscious, intelligent beings (ourselves) also be laws that those conscious intelligent beings:n can comprehend?n find to be aesthetically beautiful?

n What gives “fire” to the law of physics; what gives palpable “reality” to the potentiality they describe? ¡

IntroductionThis Week: A Multiverse with a Beginning?

n But first this week we will briefly wrap up a “loose end.”n In week 1: we saw how the beginning of our universe in the Big

Bang empowers the Cosmological Argument for God’s Existence.n However: what if the Big Bang was not the beginning of physical reality?n What if the Big Bang was the “sprouting” of our universe from another

universe in a Multiverse?n Does this possibility again put the Cosmological Argument for God’s

existence back into limbo? ¡

A Multiverse with a Beginning?Cosmological Argument

n The traditional “Cosmological Argument” for the existence of Godsays:n 1. Everything we see in this world is caused.n 2. Nothing can be the cause of itself.n 3. There cannot be an infinite regress of causes.Therefore:n 4. There must exist an uncaused first cause not of this world.n 5. The word God means “uncaused first cause not of this world”.n 6. Therefore, God exists.

n Philosophy courses routinely note this argument fails because of premise 3, “There cannot be an infinite regress of causes.” ¡

Page 17: God and the Multiverse · 2020-05-24 · A Fortunate Universe. Life in a Finely Tuned Cosmos. Cambridge University Press, 2016. ISBN 978-1107156616 n Delia Perlovand Alex Vilenkin,

A Multiverse with a Beginning?Cosmological Argument

n However the Big Bang proves that premise 3 is in fact correct. There cannot be an infinite regress of causes, for the universe is finite in time; the universe has a definite beginning in time.

n Therefore the traditional “Cosmological Argument” for the existence of God (defined as the “uncaused first cause, not of this world”) does work to prove the existence of God. ¡

A Multiverse with a Beginning?But Was the Big Bang the Beginning?

n The Big Bang is the beginning of our known Universe.

n But is the Big Bang really the beginning of all of physical reality?n Could there have been another physical reality,

another “universe” that gave rise to our universe?n Could there be other universes, separate from our

own?n There is currently not a shred of observational

evidence for any other universe. ¡

A Multiverse with a Beginning?But Was the Big Bang the Beginning?

n But:n because of a persistent philosophical preference

(bias?) for an eternal universe among cosmologists, and

n to explain the apparent “fine-tuning” of the universe for life (last week’s topic), and

n because it is the job of a scientist to try to find “natural” explanations for whatever mystery they can,

n Many cosmologists have explored the possibility that there is “Multiverse” of many universes out there, that our universe is but a recent sprout of a “Multiverse.” ¡

A Multiverse with a Beginning?Multiverse Models

n Multiverse models that might give rise to our universe include:n Bouncing Multiverse,n The Eternal or Chaotic Inflation Multiverse,n The String / M-Theory Landscape Multiverse,n Braneworld Cyclic Multiverse = Ekpyrotic

Multiverse. ¡

A Multiverse with a Beginning?Was the Big Bang the Beginning?

n It turns out however, that all viable Multiverse models still require a beginning because of: n The Second Law of Thermodynamics: entropy must increase in any

universe (or Multiverse), andn the Borde-Vilenkin-Guth (BVG) Theorem: Any universe (or

Multiverse) that has an average expansion greater than zero must have had a beginning. ¡

A Multiverse with a Beginning?Second Law of Thermodynamics: Entropy

n Any universe runs on energy and entropy.n Entropy (loosely) is a measure of the disorder in a system. The amount of

disorder in the Universe (or any isolated part of it) never spontaneously decreases (= The Second Law of Thermodynamics):n the kitchen never cleans itself,n desks never stay neat on their own,n broken vases never mend themselves.

n More fundamentally:n entropy is a measure of how much useful or free energy exists in a system:n a system with low entropy (lots of order) has energy that can be extracted and

converted into another form: it has useful energy;n a system with high entropy (lots of disorder) has energy that is stuck; it cannot be

used or tapped. ¡

Page 23: God and the Multiverse · 2020-05-24 · A Fortunate Universe. Life in a Finely Tuned Cosmos. Cambridge University Press, 2016. ISBN 978-1107156616 n Delia Perlovand Alex Vilenkin,

A Multiverse with a Beginning?Second Law of Thermodynamics: Entropy

n As energy flows, the total entropy (amount of disorder) never decreases; nearly all of the time the total entropy increases.

n The total entropy in the universe is thus increasing as the universe generates energy, and the total amount of available energy to do things in the universe is decreasing.

n You can never build a perpetual motion machine because:n As any isolated system generates energy to do work, its entropy increases.n As its entropy increases, the amount of available energy to do work decreases.n Eventually the system will “run down,” its entropy becoming so high it has no

available energy to do any work.n Any eternal multiverse would have similarly “run down” a near eternity ago.

n A Multiverse therefore, cannot be eternal, but must at some point, have had a beginning. ¡

A Multiverse with a Beginning?Borde-Vilenkin-Guth (BVG) Theorem

n A second reason why any multiverse must at some point have had a beginning is the Borde-Vilenkin-Guth (BVG) Theorem in cosmology: Any universe (or multiverse) that has an average expansion greater than zero must have had a beginning (a past space-time boundary) – regardless of the physics of that universe.

n All reasonable, proposed multiverse models have an average expansion rate greater than zero, and hence must have a beginning.

n Therefore the “Cosmological Argument” for the existence of God (= “uncaused first cause, not of this world”) is still valid. ¡

n Why (by the way) did God choose to create the unimaginably vast Universe we know we live within?

n Why might God have chosen to create not one vast universe, but an even greater Multiverse?

n In our time, C. S. Lewis (1898-1963), in his fantasy series Chronicles of Narnia, imagines God to have created a large number of different realms of being.

n In the 16th century, the Dominican friar, philosopher, mathematician and astronomer Giordano Bruno (1548-1600) declared:n “Thus is the excellence of God magnified and the

greatness of his kingdom made manifest; he is glorified not in one, but in countless suns; not in a single earth, but in a thousand, I say, in an infinity of worlds.” ¡

The Laws of PhysicsOrder in Nature

n If we study the world around us, we see order, striking regularities:n The orbits of the planets and their moons are simple geometrical

shapes; their motions display precise mathematical rhythms.n Patterns and rhythms are found within atoms.n Bridges and machines behave in an ordered and predictable manner.

n These regularities are clearly real; they are not merely patterns “imposed on” nature by our minds.

n Physicists, discerning these fundamental patterns, n have found they can be best distilled and expressed using

mathematics.n have come to regard them as “laws” that do not merely describe, but

prescribe, that govern the universe. They are the eternal, bedrock truths upon which the universe is built. ¡

n Remarkably, these mathematical distillations of the regularities seen in nature have allowed us to uncover new things in nature, often things we never suspected:n Newton’s law of gravity, for example, gives an accurate

account of planetary motion, but it also explains the ocean tides, the shape of the Earth, the motion of spacecraft, and much else.

n Maxwell’s Theory of Electromagnetism went far beyond a description of electricity and magnetism, by explaining the nature of light waves and predicting the existence of radio waves.

n Study and formulation of the truly basic Laws of Physicshave revealed deep interconnections between different physical processes, connections that we otherwise never would have discerned or even guessed. ¡

The Laws of PhysicsNature of the Laws

n So what is the true nature of these Laws of Physics? In what sense do they “exist,” and where do they “exist”?

n Most scientists think of the Laws of Physics as something “out there,” that they are discovering, something transcendental.

n A related question: all of the fundamental Laws of Physics are expressed in mathematical form. What is the nature of mathematics? Where do mathematical forms and structuresexist?n Galileo: “The great book of nature can be read only by

those who know the language in which it was written. And this language is mathematics.”

n English Astronomer James Jean (pioneer in the study of stars): “The universe appears to have been designed by a pure mathematician.”

n Many mathematicians also think of themselves as “discovering” mathematics forms and structures that exist “out there,” forms and structures that exist in a transcendental realm. ¡

complication of the structure of Mandelbrot’s set cannot really be fully comprehended by any one of us, nor can it be fully revealed by any computer. It would seem that this structure is not just part of our minds, but it has a reality of its own. . . . The computer is being used in essentially the same way that the experimental physicist uses a piece of experimental apparatus to explore the structure of the physical world. The Mandelbrot set is not an invention of the human mind: it was a discovery. Like Mount Everest, the Mandelbrot set is just there.” ¡

Intelligible LawsWhy are the Laws Comprehensible?

n Human beings have come to understand the world, at least in part, through the processes of reasoning and science.

n We have methodically explored our physical world, as well as mathematics, and by so doing have unraveled some of the hidden “cosmic code,” the “Laws of Physics,” the subtle tune to which nature dances.

n There is nothing in the Multiverseexplanation for why the universe appears designed to produce life that requires that life have such a deep level of involvement, such a deep level of connection with the Laws of the Universe or Multiverse. ¡Neil Armstrong on the Moon, Apollo

Intelligible LawsWhy are the Laws Comprehensible?n That is: there is no obvious reason why we humans should be

capable of comprehending the fundamental Laws of Physics that undergird the universe.n If there is no God, if we are merely products of a mindless evolution,

merely creatures formed in a jungle crucible of “dog eat dog” natural selection and survival of the fitness, what evolutionary purpose was served by our ability to comprehend higher mathematics or discern quantum mechanics?

n If Window 7 involves 39 million lines of source code, Facebook 61 million lines of source code, and Google 2 billion lines of source code, wouldn’t you expect that any “cosmic code” that undergirds the operation of the universe would most likely be incomprehensible by any finite intelligent being? ¡

Beautiful to Us?

“Beautiful” LawsBeauty, a Guide to Discovery in Physics

n Not only are the Laws of Physics comprehensible to humans, but theoretical physicists – those who spend their lives studying the Laws – describe the laws as aesthetically beautiful.

n It is widely believed among scientists that beauty is a reliable guide to truth, and many advances in theoretical physics have been made by the theorist demanding mathematical elegance of a new theory.

n Einstein, when discussing an experimental test of his aesthetically elegant General Theory of Relativity, was once asked what he would do if the experiment didn’t agree with the theory. He was unperturbed at the prospect. “So much the worse for the experiment,” he retorted. “The theory is right!” ¡

“Beautiful” LawsBeauty, a Guide to Discovery in Physics

n Paul Dirac, the theoretical physicist whose aesthetic deliberations led him to construct a mathematically more elegant equation for the electron, which then led to the successful prediction of the existence of antimatter, echoed these sentiments when he judged that “it is more important to have beauty in one’s equations than to have them fit experiment.”

n Roger Penrose, the mathematical physicist, describes creative work in physics as the creative mind “breaking through” into the Platonic realm to glimpse mathematical forms which are in some way beautiful:n He cites beauty as a guiding principle in much of his mathematical

work. n Countering a view of mathematics as cold, dry, and rigorous discipline,

Penrose notes: “Rigorous argument is usually the last step! Before that, one has to make many guesses, and for these, aesthetic convictions are enormously important.” ¡Paul Dirac, 1902-1984

“Beautiful” LawsElegance and Beauty of

Maxwell’s Equationsn As a college sophomore physics major at Rice

University, when we finished a year of study of Maxwell’s four equations that encoded all the phenomenon of electromagnetism, it seemed very appropriate to: n celebrate the elegance and beauty of those four

equations, an elegance and beauty that we physics students could now appreciate to some degree,

n acknowledge the ecstatic “high” many of us now felt,in the manner our physics professor proceeded to do:

Giving “Reality” to PossibilityWhat is the Source of Being?

n The Laws of Physics prescribe the behavior of the fundamental constituents of the universe.

n But knowing the law, the prescription, the “cosmic code,” does not explain:n the existence of the universe, n the fact the universe is,n that the universe has being.

n The Laws of Physics, the “cosmic code,” only describes possibility, potentiality. It is the “software” that prescribes the behavior of “hardware.” It is the “dream” of a possible world.

n What gives the “hardware” being / palpable reality? What makes the “dream” real? ¡

Giving “Reality” to PossibilityWhat is the Source of Being?

n Perhaps someday science will find the “Final Theory of Everything,” the entire cosmic code that prescribes the behavior of everything in the universe.

n Such a “Final Theory of Everything” will still only be:n the code or law for how “things” behave,n “software” that prescribes the behavior of “hardware,”n the “dream” of a possible world, a world that has somehow become real.

n A Final Theory of Everything can never answer the questions:n What gives “being” to the “things”?n What creates and sustains the “hardware”?n What made the possible, “dream” world into a “real” world? ¡

Putting It All TogetherSummary of the Problems

n Week 1 & 3: The Universe or the Multiverse had a beginning, before which there was nothing. Yet from nothing, comes nothing. What then could have caused the Universe / Multiverse to begin?

n Week 2: How do we explain that the Universe appears to be incredibly fine-tuned – as if designed -- to be fruitful of life?

n This Week: n How do we explain that the Laws of Physics are both comprehensible and

aesthetically beautiful to the life the universe appears designed to produce?n What gives “fire” to the Laws of Physics; what gives palpable “reality” /

being itself to the potentiality they describe? ¡

Putting It All TogetherThe Best Explanation

n The best explanation, the only explanation that can answer all questions is:n a creator God who deliberately created a universe — or multiverse —

that would be fruitful of conscious, intelligent life, n a God who wanted that conscious, intelligent life, intended to reflect

God’s “image and likeness,” to have some understanding and aesthetic appreciation of the creation, an understanding and aesthetic appreciation that they could share with the Creator. ¡

Putting It All TogetherThe Best Explanation

n A common objection is: but who created God? What caused God?n In our “realm of reality” everything has a cause that is not itself;

everything is dependent or contingent on something else.n But it is fully logical and coherent to say there could be realm of reality

and a Being that is not caused or contingent on something else.n Indeed, such a Being is logically necessary to explain any realm of

reality where everything is dependent on / contingent on / caused bysomething else.

n God is this necessary Being, a Being not dependent on anything else, an uncaused Being. ¡

Putting It All TogetherThe Best Explanation

n This then is the description of God that “Natural Theology” (the name for what we’ve been doing these past 3 weeks!) has led us to:n a creator God who deliberately created a universe — or multiverse —

that would be fruitful of conscious, intelligent life, n a God who wanted that conscious, intelligent life, intended to reflect

God’s “image and likeness,” to have some understanding and aesthetic appreciation of the creation, an understanding and aesthetic appreciation that they could share with the Creator.

n Such a God is fully consistent with God revealed to us in the Scripture, with God revealed to us in Jesus, The Christ, Our Lord and Savior. ¡
