Neil Shenvi: can quantum fluctuations make something appear out of nothing?

Christianity and the progress of science

New article from Dr. Neil Shenvi.

Author bio:

As it says on the main page, my name is Neil Shenvi; I am currently a research scientist with Prof. Weitao Yang at Duke University in the Department of Chemistry. I was born in Santa Cruz, California, but grew up in Wilmington, Delaware. I attended Princeton University as an undergraduate where I worked on high-dimensional function approximation with Professor Herschel Rabitz. I became a Christian in Berkeley, CA where I did my PhD in Theoretical Chemistry at UC – Berkeley with Professor Birgitta Whaley. The subject of my PhD dissertation was quantum computation, including topics in quantum random walks, cavity quantum electrodynamics, spin physics, and the N-representability problem. From 2005-2010, I worked as a postdoctoral associate with Prof. John Tully at Yale where I did research into nonadiabatic dynamics, electron transfer, and surface science.

Here is the introduction to the new article:

Many modern Christian apologists such as William Lane Craig or John Lennox present the origin of the universe in the finite past as evidence that God exists. In response, many modern atheists have sought to undermine such arguments by claiming that the existence of God is not required to account for the universe’s origin, usually by appealing to various scientific models of the universe’s origin. Because my expertise is in theoretical chemistry and quantum physics rather than in cosmology, I don’t have the background to evaluate the scientific plausibility of these cosmological models as alternatives to traditional Big Bang cosmology (nor -I expect- do most atheists!) However, I am qualified to address a claim that I frequently see advanced on the internet as a purportedly knock-down response to the claims of theists: the idea that ‘quantum fluctuations’ in some vague and unspecified sense explain the universe’s origin. In this essay, I’ll briefly explain what quantum fluctuations are and why they should not be invoked to explain the origin of the material universe out of nothing.

My argument is straighforward:

  • P1. If a ‘quantum fluctuation’ occurs, then it can be described by a wavefunction
  • P2. Wavefunctions describe ‘something’, not ‘nothing’
  • C. Therefore, if a ‘quantum fluctuation’ occurs, then it is ‘something’ not ‘nothing’

If this argument is correct, then atheists should not argue that ‘quantum fluctuations’ show that ‘something’ can come from ‘nothing’ because quantum fluctuations assume the existence of ‘something’ not ‘nothing’.

Quantum mechanics is a pretty mysterious area for me, but it’s Neil’s specialty.

Here is his argument in brief:

  • P1. If a ‘quantum fluctuation’ occurs, then it can be described by a wavefunction
  • P2. Wavefunctions describe ‘something’, not ‘nothing’
  • C. Therefore, if a ‘quantum fluctuation’ occurs, then it is ‘something’ not ‘nothing’

He writes:

Regardless of how we view the ontological status of wavefunctions, there is little question that they somehow describe something that actually exists. To say it another way, it seems extremely strange to insist that this particular wavefunction describes something which does not exist! When we make use of wavefunctions in experimental physics, they never refer to ‘nothing’; they always refer to ‘something.’ Even the ‘quantum vacuum’, which people sometimes confuse with ‘nothing’, actually refers to an entity with real properties, the most obvious of which is a zero-point energy that has measurable effects on experiments. To posit a wavefunction which describes ‘nothing’ is therefore to posit a wavefunction which is unlike any wavefunction we’ve ever encountered.

So, you can’t get something from nothing by appealing to quantum mechanics after all.

Now, I’ll just add to his article based on something he mentioned – the quantum vacuum. A further requirement of cosmologies that have our universe come into being as a result of a quantum fluctuation is that there exists a quantum vacuum outside our universe that provides the environment for the quantum fluctuation that creates the universe. And of course, this quantum vacuum is not nothing. Alexander Vilenkin explains:

And of course, we have no direct evidence of that quantum vacuum that must exist outside of our universe. If it exists, then it’s outside our universe – outside of our ability to investigate it. The only argument for its existence is that naturalists need it to be there in order to undermine the cosmological argument.

Here’s William Lane Craig talking about quantum vacuum models of the universe:

William Lane Craig has an article that he published a while back which lists problems with naturalistic cosmologies.

I hope that’s enough for everyone to respond to the speculation that QM can cause a beginning of the universe out of nothing.

Previously, I’ve featured Neil’s defense of objective morality, his lecture on science and religion, his lecture on the resurrection of Jesus, and his introduction to quantum mechanics, all of which were really popular. These are easy to understand, but substantive, too.

William Lane Craig debates Peter Atkins: Does God Exist?

Here is the video of a debate with Peter Atkins, from the Reasonable Faith speaking tour in the UK:

This is a must-see debate. It was extremely fun to watch.

Details:

On Wednesday 26th October 2011 William Lane Craig debated Peter Atkins on the topic: Does God Exist? This debate took place at the University of Manchester  as part of the UK Reasonable Faith Tour with William Lane Craig. The debate was chaired by Christopher Whitehead, Head of Chemistry School at the University. Post-debate discussion was moderated by Peter S Williams, Philosopher in Residence at the Damaris Trust, UK.

Dr. William Lane Craig:

William Lane Craig (born August 23, 1949) is an American analytic philosopher, philosophical theologian, and Christian apologist. He is known for his work on the philosophy of time and the philosophy of religion, specifically the existence of God and the defense of Christian theism. He has authored or edited over 30 books including The Kalam Cosmological Argument (1979), Theism, Atheism and Big Bang Cosmology(co-authored with Quentin Smith, 1993), Time and Eternity: Exploring God’s Relationship to Time (2001), and Einstein, Relativity and Absolute Simultaneity (co-edited with Quentin Smith, 2007).

Craig received a Bachelor of Arts degree in communications from Wheaton College, Illinois, in 1971 and two summa cum laudemaster’s degrees from Trinity Evangelical Divinity School in Deerfield, Illinois, in 1975, in philosophy of religion and ecclesiastical history. He earned a Ph.D. in philosophy under John Hick at the University of Birmingham, England in 1977 and a Th.D. underWolfhart Pannenberg at the University of Munich in 1984.

Dr. Peter Atkins:

Peter William Atkins (born 10 August 1940) is a British chemist and former Professor of Chemistry at the University of Oxford and a Fellow of Lincoln College. He is a prolific writer of popular chemistry textbooks, including Physical ChemistryInorganic Chemistry, and Molecular Quantum Mechanics. 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 studied chemistry at the University of Leicester, obtaining a bachelor’s degree in chemistry, and – in 1964 – a PhD for research into electron spin resonance spectroscopy, and other aspects of theoretical chemistry. Atkins then took a postdoctoral position at the UCLA as aHarkness Fellow of the Commonwealth fund. He returned to Oxford in 1965 as fellow and tutor of Lincoln College, and lecturer in physical chemistry (later, professor of physical chemistry).

You can get the audio of the debate here, along with links to their previous debate from 1998. This debate is accessible and understandable to novice-level Christians.

I am happy when debates like this come out. I have friends who are Christians who doubt the importance of apologetics in evangelism, because they don’t think that apologists can prove anything or win arguments. I have friends who are skeptical of using arguments that assume a 14-billion year old universe, because they think that the Big Bang is compatible with atheism (!). I have friends who think that philosophical arguments have no persuasive force. I have friends who think that nothing can be proven from history, beyond a reasonable doubt. I have co-workers who ask me whether anyone wins these debates. I think that this debate answers all of those questions.

This debate clearly shows why Christians should not shy away from studying science, philosophy and history. We will not discover anything that harms Christian theism by thinking logically and by looking at the evidence. To the contrary, it is the atheist who makes war on the progress of science, and who is forced to resist the clear experimental evidence, and to resort to baseless speculations and blind faith. If you want to see a good debate with an intelligent atheist, I recommend watching the debate between William Lane Craig and Peter Millican instead. But if you want to see a really, really overwhelming defeat for atheism, watch this debate. It is very clear at the end of this debate why Richard Dawkins refused to debate William Lane Craig at Oxford.

SUMMARY OF THE OPENING SPEECHES

I only had time to summarize the first two speeches. Keep in mind that Dr. Craig always shines in his rebuttals, and this debate is no different. So you’ll want to watch those rebuttals. Dr. Atkins literally says in this debate in his first rebuttal “There was nothing here originally. There is nothing here now. But it is an interesting form of nothing which seems to be something.” And the audience laughs nervously. This debate is like that. You will see a clear winner and clear loser in this debate. This fight is decided by knockout.

William Lane Craig opening speech:

1. the origin of the universe
2. the moral argument
3. the resurrection of Jesus

Peter Atkins opening speech:

1. Dr. Craig is stupid, lazy and evil:
– Dr. Craig’s arguments are old: from the 11th century! Old arguments can’t be true
– Dr. Craig is just asserting that “God did it” because he is lazy
– Dr. Craig feels pressured to agree with the theistic majority
– Dr. Craig needs a psychological crutch to comfort him
– Dr. Craig is fearful of death
– Dr. Craig is just wishing for an eternal life of bliss
– Dr. Craig is driven by his heart, and not by his head

2. Origin of the universe:
– Maybe the universe is eternal and has no beginning – we don’t know
– Maybe mommy universes can give birth to daughter universes
– It is naive to think that a cause is needed to cause the creation of the universe from nothing
– Science is just about to show how it is possible that something appears out of nothing without cause
– Some scientists have already begun to speculate about about how something can come into being out of nothing
– Maybe nothing is not really nothing, but it is actually something
– It would be admitting defeat to say that God created the universe out of nothing

3. Fine-Tuning:
– It could be the case that the fundamental constants are not variable
– It could be the case that the fine-tuning of the cosmic constants is a happy accident
– It could be the case that there are billions of billions of unobservable universes that are not fine tuned
– It could be the case that the cosmic constants in these billions and billions of unobservable universes are all random so that some are fine-tuned
– Anyone who infers that an intelligence is the best explanation of a finely-tuned set of life-permitting cosmic constants is lazy

4. Purpose:
– Philosophers and theologians are stupid
– I don’t think that there is purpose in the universe
– I think that the universe is more grand if there is no purpose, so there is no purpose

5. Miracles:
– I don’t think that miracles happen
– The resurrection is a fabrication
– It could be the case that Jesus didn’t exist
– It could be the case that Jesus wasn’t really crucified
– It could be the case that Jesus didn’t  really die after being crucified
– It could be the case that the disciples stole his body
– It could be the case that the women went to the wrong hole in the ground
– the gospels are political propaganda written long after the events they are reporting on

6. Theodicy:
– God has no morally sufficient reason for allowing humans to perform actions that result in suffering
– God has no morally sufficient reason for allowing nature to cause suffering

7. Morality:
–  customs and conventions emerges arbitrarily in different times and places based on an awareness of the consequences of actions, as well as various anecdotes and experiences
–  these customs and conventions are decided based on the goal for survival, in much the same way as politeness and manners emerge for decorum and to avoid offense
– it is childish to presume that there is an umpire God who decides moral values and duties

8. Religious believers are stupid, lazy and evil:
– the notion of God has arisen because people are stupid and want to be comforted
– there are no arguments or evidences for belief in God
– people who believe in God do not think, but instead take refuge in incomprehensible nonsense

The kalam cosmological argument defended in a peer-reviewed science journal

Here’s the peer-reviewed article. It appears in a scientific journal focused on astrophysics.

Here’s the abstract:

Both cosmology and philosophy trace their roots to the wonder felt by the ancient Greeks as they contemplated the universe. The ultimate question remains why the universe exists rather than nothing. This question led Leibniz to postulate the existence of a metaphysically necessary being, which he identified as God. Leibniz’s critics, however, disputed this identification, claiming that the space-time universe itself may be the metaphysically necessary being. The discovery during this century that the universe began to exist, however, calls into question the universe’s status as metaphysically necessary, since any necessary being must be eternal in its existence. Although various cosmogonic models claiming to avert the beginning of the universe predicted by the standard model have been and continue to be offered, no model involving an eternal universe has proved as plausible as the standard model. Unless we are to assert that the universe simply sprang into being uncaused out of nothing, we are thus led to Leibniz’s conclusion. Several objections to inferring a supernatural cause of the origin of the universe are considered and found to be unsound.

The whole text of the article is posted online here.

Here’s an excerpt in which the author, Dr. William Lane Craig, explains the Big Bang cosmology:

The monumental significance of the Friedman-Lemaitre model lay in its historization of the universe. As one commentator has remarked, up to this time the idea of the expansion of the universe “was absolutely beyond comprehension. Throughout all of human history the universe was regarded as fixed and immutable and the idea that it might actually be changing was inconceivable.”{8} But if the Friedman-Lemaitre model were correct, the universe could no longer be adequately treated as a static entity existing, in effect, timelessly. Rather the universe has a history, and time will not be matter of indifference for our investigation of the cosmos. In 1929 Edwin Hubble’s measurements of the red-shift in the optical spectra of light from distant galaxies,{9} which was taken to indicate a universal recessional motion of the light sources in the line of sight, provided a dramatic verification of the Friedman-Lemaitre model. Incredibly, what Hubble had discovered was the isotropic expansion of the universe predicted by Friedman and Lemaitre. It marked a veritable turning point in the history of science. “Of all the great predictions that science has ever made over the centuries,” exclaims John Wheeler, “was there ever one greater than this, to predict, and predict correctly, and predict against all expectation a phenomenon so fantastic as the expansion of the universe?”{10}

As a GTR-based theory, the Friedman-Lemaitre model does not describe the expansion of the material content of the universe into a pre-existing, empty, Newtonian space, but rather the expansion of space itself. This has the astonishing implication that as one reverses the expansion and extrapolates back in time, space-time curvature becomes progressively greater until one finally arrives at a singular state at which space-time curvature becomes infinite. This state therefore constitutes an edge or boundary to space-time itself. P. C. W. Davies comments,

An initial cosmological singularity . . . forms a past temporal extremity to the universe. We cannot continue physical reasoning, or even the concept of spacetime, through such an extremity. . . . On this view the big bang represents the creation event; the creation not only of all the matter and energy in the universe, but also of spacetime itself.{11}

The popular expression “Big Bang,” originally a derisive term coined by Fred Hoyle to characterize the beginning of the universe predicted by the Friedman-Lemaitre model, is thus potentially misleading, since the expansion cannot be visualized from the outside (there being no “outside,” just as there is no “before” with respect to the Big Bang).{12}

The standard Big Bang model thus describes a universe which is not eternal in the past, but which came into being a finite time ago. Moreover,–and this deserves underscoring–the origin it posits is an absolute origin ex nihilo. For not only all matter and energy, but space and time themselves come into being at the initial cosmological singularity. As Barrow and Tipler emphasize, “At this singularity, space and time came into existence; literally nothing existed before the singularity, so, if the Universe originated at such a singularity, we would truly have a creation ex nihilo.“{13}

[…]On such a model the universe originates ex nihilo in the sense that at the initial singularity it is true that There is no earlier space-time point or it is false that Something existed prior to the singularity.

Every theist should be able to understand and defend this argument. It is a scientific refutation of materialism, and it is supported by six lines of scientific evidence – all of which emerged as science has progressed.

Scientific evidence:

  1. Einstein’s theory of general relativity (GTR)
  2. the red-shifting of light from distant galaxies implies an expanding universe
  3. the cosmic background radiation (which also disproves the oscillating model of the universe)
  4. the second law of thermodynamics applied to star formation theory
  5. hydrogen-helium abundance predictions
  6. radioactive element abundance predictions

Those are the scientific discoveries that have led us to the beginning of the universe, which support’s Dr. Craig’s argument.

This is the kind of evidence I expect all Christian theists to be using when discussing the question of whether God exists. Scientific evidence. When talking to non-Christians, we first need to show that we understand science, because science is a reliable and respected way of getting knowledge about the universe. Non-Christians do not accept the Bible, but they do accept science, so we begin evangelism with science. Science (experimental, testable, repeatable science) should set limits on what anyone can believe – including non-Christians, who might otherwise not be inclined to listen to Bible verses and theology. Important: it’s not a good idea to discuss the resurrection of Jesus with a person who does not accept the scientific evidence for a Creator of the universe.

The Big Bang is not compatible with atheism

According to the Secular Humanist Manifesto, atheism is committed to an eternally existing universe, (See the first item: “Religious humanists regard the universe as self-existing and not created.”). If something non-material brought all existing matter into being, that would be a supernatural cause, and atheists deny that anything supernatural exists. The standard Big Bang theory requires that all the matter in the universe come into being out of nothing. This falsifies eternal models of the universe, which are required by the atheistic worldview.

This is one of my favorite lectures.

The lecture:

Dr. Strauss delivered this lecture at Stanford University in 1999. It is fairly easy to understand, and it even includes useful dating tips.

Here is a clip:

The full video can be watched on Vimeo:

Summary:

What does science tell us about God?
– the discoveries of Copernicus made humans less significant in the universe
– the discoveries of Darwin should that humans are an accident
– but this all pre-modern science
– what do the latest findings of science say about God?

Evidence #1: the origin of the universe
– the steady state model supports atheism, but was disproved by the latest discoveries
– the oscillating model supports atheism, but was disproved by the latest discoveries
– the big bang model supports theism, and it is supported by multiple recent discoveries
– the quantum gravity model supports atheism, but it pure theory and has never been tested or confirmed by experiment and observation

Evidence #2: the fine-tuning of physical constants for life
– there are over 100 examples of constants that must be selected within a narrow range in order for the universe to support the minimal requirements for life
– example: mass density
– example: strong nuclear force (what he studies)
– example: carbon formation

Evidence #3: the fine-tuning of our planet for habitability
– the type of galaxy and our location in it
– our solar system and our star
– our planet
– our moon

It’s a good lecture explaining a couple of basic arguments for a cosmic Creator and Designer. If you add the origin of life and the Cambrian explosion (Stephen C. Meyer’s arguments), then you will be solid on the basic scientific arguments for a Creator and Designer of the universe.

About the speaker:

His full biography is here.

Summary:

  • It used to be true that most of the great scientists were believers in God
  • But now science has advanced and we have better instruments – is it still true?
  • Today, many people believe that science has shows that the universe and Earth are not special
  • We used to believe that the Earth was the center of the universe, and Darwin showed we are not designed
  • The problem with this view is that it is based on old science, not modern science
  • Three topics: origin of the universe, fine-tuning of the universe, the Rare Earth hypothesis

Experimental evidence for the origin of the universe:

  • #1: Hubble discovered that the universe expands because of redshifting of light from distant galaxies
  • #2: Measurements of the cosmic microwave background radiation show the universe had a beginnning
  • #3: Measurements of the light element (hydrogen and helium) abundances confirm an origin of the universe
  • The best explanation for an absolute origin of space, time, matter and energy is a supernatural cause

Experimental evidence for the design of the universe:

  • #1: The amount of matter: a bit less = no stars and galaxies, a bit more = universe recollapses
  • #2: The strong force: a bit more = only hydrogen, a bit more = little or no hydrogen
  • #3: Carbon resonance level: a bit higher = no carbon, a bit lower = no carbon

Experimental evidence for galactic, stellar and planetary habitability:

  • #1: Galaxy: produces high number of heavy elements and low radiation
  • #2: Star: long stable lifetime, burns bright, bachelor star, third generation star (10 billion years must elapsed),
  • #3: Planet: mass of planet, stable orbit, liquid water, tectonic activity, tilt, moon

Naturalistic explanations:

  • Humans evolve to the point where they reach back in time and create finely-tuned universe
  • Eternally existing multiverse

Hawking and Mlodinow response to Rare Earth:

  • There are lots of planets so one must support life
  • Odds of a planet that supports life are low even with 10^22 planets

Hawking and Mlodinow proposal of M-theory multiverse:

  • There is no experimental evidence for M-theory being true
  • M-theory is not testable now and is not likely to be testable in the future
  • But science is about making testable predictions, not about blind speculation

Hawking and Mlodinow no-boundary proposal:

  • This theory requires the laws of physics to exist prior to the universe
  • But where do you get laws of physics before there is any physical world?
  • There is no experimental evidence for no-boundary proposal
  • All the evidence we have now (redshift, CMBR, H-He abundances) is for Big Bang

What science has revealed provide abundant evidence for a transcendent Creator and Designer.
