Alexander Vilenkin: “All the evidence we have says that the universe had a beginning”

I’ve decided to explain why physicists believe that there was a creation event in this post. That is to say, I’ve decided to let famous cosmologist Alexander Vilenkin do it.

From Uncommon Descent.

Excerpt:

Did the cosmos have a beginning? The Big Bang theory seems to suggest it did, but in recent decades, cosmologists have concocted elaborate theories – for example, an eternally inflating universe or a cyclic universe – which claim to avoid the need for a beginning of the cosmos. Now it appears that the universe really had a beginning after all, even if it wasn’t necessarily the Big Bang.

At a meeting of scientists – titled “State of the Universe” – convened last week at Cambridge University to honor Stephen Hawking’s 70th birthday, cosmologist Alexander Vilenkin of Tufts University in Boston presented evidence that the universe is not eternal after all, leaving scientists at a loss to explain how the cosmos got started without a supernatural creator. The meeting was reported in New Scientist magazine (Why physicists can’t avoid a creation event, 11 January 2012).

[…]In his presentation, Professor Vilenkin discussed three theories which claim to avoid the need for a beginning of the cosmos.

The three theories are chaotic inflationary model, the oscillating model and quantum gravity model. Regular readers will know that those have all been addressed in William Lane Craig’s peer-reviewed paper that evaluates alternatives to the standard Big Bang cosmology.

But let’s see what Vilenkin said.

More:

One popular theory is eternal inflation. Most readers will be familiar with the theory of inflation, which says that the universe increased in volume by a factor of at least 10^78 in its very early stages (from 10^−36 seconds after the Big Bang to sometime between 10^−33 and 10^−32 seconds), before settling into the slower rate of expansion that we see today. The theory of eternal inflation goes further, and holds that the universe is constantly giving birth to smaller “bubble” universes within an ever-expanding multiverse. Each bubble universe undergoes its own initial period of inflation. In some versions of the theory, the bubbles go both backwards and forwards in time, allowing the possibility of an infinite past. Trouble is, the value of one particular cosmic parameter rules out that possibility:

But in 2003, a team including Vilenkin and Guth considered what eternal inflation would mean for the Hubble constant, which describes mathematically the expansion of the universe. They found that the equations didn’t work (Physical Review Letters, DOI: 10.1103/physrevlett.90.151301). “You can’t construct a space-time with this property,” says Vilenkin. It turns out that the constant has a lower limit that prevents inflation in both time directions. “It can’t possibly be eternal in the past,” says Vilenkin. “There must be some kind of boundary.”

A second option explored by Vilenkin was that of a cyclic universe, where the universe goes through an infinite series of big bangs and crunches, with no specific beginning. It was even claimed that a cyclic universe could explain the low observed value of the cosmological constant. But as Vilenkin found, there’s a problem if you look at the disorder in the universe:

Disorder increases with time. So following each cycle, the universe must get more and more disordered. But if there has already been an infinite number of cycles, the universe we inhabit now should be in a state of maximum disorder. Such a universe would be uniformly lukewarm and featureless, and definitely lacking such complicated beings as stars, planets and physicists – nothing like the one we see around us.

One way around that is to propose that the universe just gets bigger with every cycle. Then the amount of disorder per volume doesn’t increase, so needn’t reach the maximum. But Vilenkin found that this scenario falls prey to the same mathematical argument as eternal inflation: if your universe keeps getting bigger, it must have started somewhere.

However, Vilenkin’s options were not exhausted yet. There was another possibility: that the universe had sprung from an eternal cosmic egg:

Vilenkin’s final strike is an attack on a third, lesser-known proposal that the cosmos existed eternally in a static state called the cosmic egg. This finally “cracked” to create the big bang, leading to the expanding universe we see today. Late last year Vilenkin and graduate student Audrey Mithani showed that the egg could not have existed forever after all, as quantum instabilities would force it to collapse after a finite amount of time (arxiv.org/abs/1110.4096). If it cracked instead, leading to the big bang, then this must have happened before it collapsed – and therefore also after a finite amount of time.

“This is also not a good candidate for a beginningless universe,” Vilenkin concludes.

So at the end of the day, what is Vilenkin’s verdict?

“All the evidence we have says that the universe had a beginning.”

This is consistent with the Borde-Guth-Vilenkin Theorem, which I blogged about before, and which William Lane Craig leveraged to his advantage in his debate with Peter Millican.

The Borde-Guth-Vilenkin (BGV) proof shows that every universe that expands must have a space-time boundary in the past. That means that no expanding universe, no matter what the model, can be eternal into the past. No one denies the expansion of space in our universe, and so we are left with a cosmic beginning. Even speculative alternative cosmologies do not escape the need for a beginning.

Conclusion

If the universe came into being out of nothing, which seems to be the case from science, then the universe has a cause. Things do not pop into being, uncaused, out of nothing. The cause of the universe must be transcendent and supernatural. It must be uncaused, because there cannot be an infinite regress of causes. It must be eternal, because it created time. It must be non-physical, because it created space. There are only two possibilities for such a cause. It could be an abstract object or an agent. Abstract objects cannot cause effects. Therefore, the cause is an agent.

Now, let’s have a discussion about this science in our churches, and see if we can’t train Christians to engage with non-Christians about the evidence so that everyone accepts what science tells us about the origin of the universe.

Gary Habermas and James Crossley discuss the minimal facts case for the resurrection

Two ninjas face off at sundown
Two ninjas face off at sundown

James Crossley is my favorite atheist ancient historian, such a straight shooter. He’s on the skeptical left, but he has a no-baloney way of talking that I really like. I was so excited to summarize this, and there’s not a speck of snark in this summary. Crossley dates the gospel of Mark 37-43 A.D., far earlier than most scholars. Justin Brierley does a great job as moderator. Gary Habermas is OK, but he is not familiar with any useful arguments for God’s existence, (kalam, fine-tuning, origin of life, Cambrian explosion, etc.), and that is a problem in this debate.

Here are the details of the debate:

Christian philosopher and historian Gary Habermas has been at the forefront of the ‘minimal facts’ approach as evidence for the resurrection of Jesus.

He debates the commonly agreed facts with agnostic New Testament scholar James Crossley and they discuss whether the miracle of the resurrection can be a historically valid explanation of the evidence.

Note: this is the first of two shows they are doing together.

The MP3 file is here.

There is also a video on YouTube:

This non-snarky summary starts at 10:52.

Summary:

  • Habermas: the minimal facts are the facts that even the majority of skeptical scholars will accept

Habermas list of minimal facts: (near universal acceptance)

  1. Jesus died by Roman crucifixion
  2. After his death, his disciples had experiences that they believed were appearances of the risen Jesus
  3. The disciples were transformed by their experiences and proclaimed his resurrection and were willing to die for their belief in the resurrection
  4. The proclamation of his resurrection was early
  5. James was converted by a post-mortem experience
  6. Paul was converted by a post-mortem experience

Habermas list of widely-accepted facts:

  1. Burial for Jesus in a private tomb
  2. The private tomb found empty
  3. The disciples despaired after Jesus was crucified
  4. The proclamation of the resurrection started in Jerusalem
  5. Changing the worship day from Saturday to Sunday

Crossley’s views on the minimal and widely-accepted facts:

  • Crossley: I am in broad agreement with what Gary said
  • Crossley: “the resurrection appearances are some of the hardest, best evidence we have” because it’s in early 1 Cor 15:3-8 creed
  • Crossley: people were convinced that they had seen the risen Christ

The burial in a private tomb:

  • Crossley: I have my doubts about the private tomb burial and the empty tomb
  • Crossley: Mark’s gospel has the burial in a private tomb by Joseph of Arimethea, and Mark is the earliest gospel
  • Crossley: I don’t have a doubt, it’s just that there are other possible alternatives, and then the tradition was invented later – but that’s just a possibility
  • Crossley: there is not enough evidence to make a decision either way on the burial

The empty tomb:

  • Habermas: there are multiple lines of evidence for the empty tomb
  • Habermas: the reason it’s not one of my minimal facts is because a quarter to a third of skeptical scholars reject it

The transformation of the followers of Jesus:

  • Crossley: “yes, clearly, I don’t think you can argue with that, it’s fairly obvious”

The conversions of James and Paul:

  • Crossley: “yes, because it’s based on 1 Corinthians 15:3-8, that report, that was handed on to him”

Where Habermas and Crossley agree:

  • Habermas: you agree with the 6 facts in the minimal facts list, and you have problems with 2 of 5 facts from the widely accepted list
  • Crossley: Yes

The empty tomb:

  • Crossley: Two problems: first, 1 Corinthians 15:3-8 doesn’t mention it, but it “probably assumes the idea that Jesus left behind an empty tomb when resurrected, I am convinced by some of the conservative arguments on that one, but it’s not hard evidence for there actually being an empty tomb”
  • Crossley: Second, “the other early source we have ends with no resurrection appearances”, it makes him a bit skeptical of the empty tomb
  • Habermas: the empty tomb is not a minimal fact, I want 90% agreement by skeptical scholars for it to be a minimal fact
  • Habermas: I have never included the empty tomb in my list of minimal facts
  • Brierley: William Lane Craig puts it in his list of minimal facts
  • Habermas: It is very well attested, so if that’s what you mean, then it’s a minimal fact, but it doesn’t have the 90% agreement like the other minimal facts
  • Habermas: I have 21 arguments for the empty tomb, and none of them require early dating of sources or traditional authorship of the gospels, e.g. – the women discovered the empty tomb, the pre-Markan source, the implications of 1 Cor 15 has some force, the sermons summary in Acts 13 which Bart Ehrman dates to 31 or 32 A.D. has putting a body down and a body coming up without being corrupted

Why is 1 Corinthians 15:3-8 more respected as a source than the gospels?

  • Habermas: There is a unanimous New Testament conclusion, across the board, from conservative to liberal, that in 1 Cor 15:3-8 Paul is presenting creedal data, Richard Bauckham says that this goes back to the early 30s A.D., Paul got this from the eyewitnesses he mentions in Galatians 1 and 2
  • Crossley: [reads 1 Corinthians:3-8 out loud], now that’s a tradition that’s handed on, this is Paul, we know this is Paul, writing mid-50s, this is kind of gold, this is the evidence I wish we had across the board

Why doesn’t James accept the resurrection:

  • Crossley: Historians should not conclude that the supernatural is real, concluding the supernatural is outside of history
  • Crossley: I am more interested in what people believed at that time
  • Brierley: as a historian, are you required to give an explanation of the commonly-accepted facts
  • Crossley: yes, historians must give their explanation for the facts
  • Crossley: we know people have visions, and how the cultural context determines the content of visions, e.g. – the background of martyrdom
  • Brierley: so you would go for the hallucination hypothesis?
  • Crossley: yes, but I prefer not to use that word

Should historians rule out the supernatural?

  • Habermas: let’s not ask what caused the event, let’s just see if the disciples thought they saw him before he died, that he died on the cross, and then believed they saw him after he died, like you might see someone in the supermarket
  • Habermas: I’m not asking whether a miracle occurred, I just want to know whether Jesus was seen after he died on the cross
  • Crossley: that sounds like the angle I’m coming at this from
  • Crossley: the problem is that there is a supernatural element to some of the appearances, so it’s not a supermarket appearances
  • Brierley: it’s not angels and hallelujah in the sky
  • Habermas: nothing like that, no light in the early accounts, fairly mundane

Does James agree that people believed they saw Jesus after his death?

  • Crossley: yes, I think that’s fairly clear that we do
  • Crossley: but historians cannot prove claims that what happened to Jesus was supernatural
  • Brierley: your view is so far from what I see on Internet atheists sites, where they say it’s all legendary accumulation, fairy tales
  • Crossley: I’m perfect comfortable with the idea – and I think it happened – that people created stories, invented stories
  • Crossley: there are too many cases where people are sincerely professing that they thought they saw Jesus after his death

Would you expect the disciples to have visions of a resurrected Jesus if nothing happened to him?

  • Habermas: the dividing line is: did something happen to Jesus, or did something happen to his disciples?
  • Habermas: the view that people were seeing a kind of ghostly Jesus (non-bodily) – a Jedi Jesus – after his death is a resurrection view, but I hold to a bodily resurrection view
  • Brierley: N.T. Wright says a resurrected Jesus was contrary to expectations – should we expect the disciples to have a vision of Jesus as resurrected?
  • Crossley: Wright generalizes too much thinking that there was a single view of the resurrection (the general resurrection at the end of the age), there are a variety of views, some are contradictory
  • Crossley: Herod Antipas thought that Jesus might be John the Baptist returned from the dead, and he knew Jesus was flesh and blood, there is the story of the dead rising in the earthquake in Matthew, there are stories of the resurrection in Maccabees, and this would influence what people expected
  • Habermas: the earliest Christian view was *bodily* resurrection
  • Crossley: yes, I think that’s right
  • Crossley: In Mark 6, they thought Jesus was a ghost, so there is room for disagreement

Why should a historian not rule out a supernatural explanation?

  • Habermas: to get to supernatural, you have to go to philosophy – it’s a worldview problem
  • Habermas: he predicted his own death and resurrection
  • Habermas: one factor is the uniqueness of Jesus
  • Habermas: the early church had belief in the bodily resurrection, and a high Christology out of the gate
  • Habermas: you might look at evidence for corroborated near-death experiences that raise the possibility of an afterlife
  • Crossley: I’m content to leave it at the level of what people believe and not draw any larger conclusions
  • Crossley: regarding the predicting his own death, the gospels are written after, so it’s not clear that these predictions predate Jesus’ death
  • Crossley: it’s not surprising that Jesus would have predicted his own death, and that he might have foreseen God vindicating him

If you admit to the possibility of miracles, is the data sufficient to conclude that the best explanation of the facts is resurrection?

  • Crossley: If we assume that God exists, and that God intervenes in history, and that this was obvious to everyone, then “of course”
  • Brierley: Are you committed to a naturalistic view of history?
  • Crossley: Not quite, broadly, yes, I am saying this all I can do
  • Brierley: should James be open to a supernatural explanation?
  • Habermas: if you adopt methodological naturalism,it colors how look at the data is seen, just like supernaturalism does

Book review of R.C. Sproul’s “If there’s a God, why are there atheists?”

I have a key that will unlock a puzzling mystery
I have a key that will unlock a puzzling mystery

Brian Auten has a book review posted up at Apologetics 315.

The book is “If There’s A God, Why Are There Atheists?”, by theologian R.C. Sproul. R.C. Sproul is one of my favorite theologians. The book in question has a very, very special place in my heart, because I think that it is one of the major reasons why I was able to resist pernicious ideas like religious pluralism and postmodernism for so long. Once you put on the glasses of Romans 1 and see for the first time what man is really doing with respect to God, you can never see things the same again. I’ll say more about this at the end, but let’s see what Brian wrote first.

The review

So often, you hear atheists complaining about religion is nothing but wish-fulfillment or some sort of crutch for people who are frightened by a variety of things. They think that God is invented to solve several problems. 1) how does the world work?, 2) is there meaning to suffering and evil?, 3) why should I be moral?, and 4) what will happen to me and my loved ones when I die?. On the atheistic view, God is just a crutch that people cling to out of weakness and ignorance. But is this really the case?

Sproul starts the book by investigating three atheists who sought to explain religious belief as a result of psychological factors.

Brian writes:

Before tackling the psychology of atheism, Sproul spends a chapter on the psychology of theism, from the perspective of Freud’s question “If there is no God, why is there religion?”11 What follows is an overview of various psychological explanations of theistic belief: Feuerbach’s “religion is a dream of the human mind.”12 Marx’s belief that religion is “due to the devious imagination of particular segment of mankind.”13 And Nietzche’s idea that “religion endures because weak men need it.”14 The author properly reiterates: “We must be careful to note that the above arguments can never be used as proof for the nonexistence of God. They can be useful for atheists who hear theists state that the only possible explanation for religion is the existence of God.”15 That being said, Sproul also reveals what these arguments presume:

Their arguments already presupposed the nonexistence of God. They were not dealing with the question, Is there a God? They were dealing with the question, Since there is no God, why is there religion?16

Sproul points out the weaknesses of each of these approaches and says “there are just as many arguments showing that unbelief has its roots in the psychological needs of man.”

Wow, could that really be true? What are the real reasons why people reject God? Does the Bible have anything to say about what those reasons are?

Brian cites Sproul’s contention:

The New Testament maintains that unbelief is generated not so much by intellectual causes as by moral and psychological ones. The problem is not that there is insufficient evidence to convince rational beings that there is a God, but that rational beings have a natural hostility to the being of God.

[…]Man’s desire is not that the omnipotent, personal Judeo-Christian God exist, but that He not exist.

In Romans 1:18-23, the apostle Paul explains what is really going on:

18The wrath of God is being revealed from heaven against all the godlessness and wickedness of men who suppress the truth by their wickedness,

19since what may be known about God is plain to them, because God has made it plain to them.

20For since the creation of the world God’s invisible qualities—his eternal power and divine nature—have been clearly seen, being understood from what has been made, so that men are without excuse.

21For although they knew God, they neither glorified him as God nor gave thanks to him, but their thinking became futile and their foolish hearts were darkened.

22Although they claimed to be wise, they became fools

23and exchanged the glory of the immortal God for images made to look like mortal man and birds and animals and reptiles.

On this blog, I regularly present many, many arguments for theism in general, and Christian theism in particular:

Sproul explains why atheists cannot allow themselves to live according to the evidence that is presented to them:

The cumulative effect of this knowledge that is clearly seen is to leave men ‘without excuse.’ Herein lies the basis of the universal guilt of man. No one can claim ignorance of the knowledge of God. No one can cite insufficient evidence for not believing in God. Though people are not persuaded by the evidence, this does not indicate an insufficiency in the evidence, but rather an insufficiency in man.

[…]The basic stages of man’s reaction to God can be formulated by means of the categories of trauma, repression, and substitution.

[…]If God exists, man cannot be a law unto himself. If God exists, man’s will-to-power is destined to run head-on into the will of God.

And this is the force that is animating atheists today. They don’t want to be accountable to God in a relationship, no matter what the evidence is. They have to deny it, so that they can be free to get the benefits of a universe designed for them, without having to give any recognition or acknowledgement back. If they have to lie to themselves to deny the evidence, they will do it. Anything to insulate themselves from the Creator and Designer who reveals himself in Jesus Christ.

The rest of the book review, and the book, deals with explaining in detail how atheists respond to an all-good, all-powerful, all-knowing Creator/Designer. I encourage you to click through and read the whole book review. You can read the review, and the book, and then investigate for yourself whether atheists really are like that.

My survey of atheists

By the way, did you all see my survey of atheists that I did a while back? It’s relevant because one of the questions I asked to my volunteers was “How you begin to follow Christ if it suddenly became clear to you that Christianity was objectively true?”. I got some very strange responses that dovetail nicely with Sproul’s book.

Here are a few of the responses:

  • I would not follow. My own goals are all that I have, and all that I would continue to have in that unlikely situation. I would not yield my autonomy to anyone no matter what their authority to command me.
  • I would not follow, because God doesn’t want humans to act any particular way, and he doesn’t care what we do.
  • I would not follow. Head is spinning. Would go to physician to find out if hallucinating.
  • I hope I would be courageous enough to dedicate my life to rebellion against God.
  • I would not have to change anything unless forced to and all that would change is my actions not my values.  I would certainly balk at someone trying to force me to change my behavior as would you if you were at the mercy of a moral objectivist who felt that all moral goodness is codified in the Koran.
  • He would have to convince me that what he wants for me is what I want for me.

This is all part of my series discussing whether morality is rationally grounded by atheism.

Well Spent Journey did a similar survey of atheists, inspired by mine, and got this result on the relevant question:

12. How would you begin to follow Jesus if it became clear to you that Christianity was true?

– Would follow (5)
– Wouldn’t follow (6)
Might follow the teachings of Jesus, but that isn’t Christianity (2)
– It would depend on how this truth was revealed (3)
– Christianity can’t be true (3)
– No answer given (4)

…What would be the hardest adjustment you would have to make to live a faithful, public Christian life?

– Adjusting wouldn’t be that difficult; would eagerly welcome knowing that Christianity was true (2)
– Praying, since it seems weird, creepy, and strange
– Trying to figure out how the Bible became so corrupted

– Trying to convince myself that the God of the Bible is deserving of worship (2)
– Don’t think it would be possible to adjust

– No clear response, or not applicable (16)

Yes, they really think like that! Just ask an atheist questions and you’ll see how “objective” they really are. Atheism is entirely psychological. It’s adopted in order to feel sufficient and to operate with autonomy, with the goal of self-centered pleasure-seeking above all. Evidence has nothing to do with it.
