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.

Did the early church invent the divinity of Jesus over a long period of time?

How early is the doctrine of the divinity of Jesus? When I answer this question, I only want to use the earliest, most reliable sources – so I can defend them on historical grounds using the standard rules of historiography. The 4 sources that I would use are as follows:

  • The early creed in 1 Corinthians 15:3-8, and 1 Corinthians 1
  • A passage in Philippians 2
  • Two passages from Mark, the earliest gospel
  • A passage from Q, which is an early source of Matthew and Luke

So let’s see the passages.

1 Corinthians

I’ve written before about the early creed in 1 Corinthians 15:3-8, which skeptical scholars date to 1-3 years after the death of Jesus, for a variety of reasons I covered in the previous post. Here’s the creed which definitely makes Jesus out to be more than an ordinary man. Ordinary men don’t get resurrection bodies after they die.

Here’s the passage: (1 Cor 15:3-8)

3For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures,

4that he was buried, that he was raised on the third day according to the Scriptures,

5and that he appeared to Peter, and then to the Twelve.

6After that, he appeared to more than five hundred of the brothers at the same time, most of whom are still living, though some have fallen asleep.

7Then he appeared to James, then to all the apostles,

8and last of all he appeared to me also, as to one abnormally born.

Additionally, 1 Corinthians 1:21-25 talks about Jesus being “the power of God and the wisdom of God”. Paul is identifying Jesus with the divine.

21For since in the wisdom of God the world through its wisdom did not know him, God was pleased through the foolishness of what was preached to save those who believe.

22Jews demand miraculous signs and Greeks look for wisdom,

23but we preach Christ crucified: a stumbling block to Jews and foolishness to Gentiles,

24but to those whom God has called, both Jews and Greeks, Christ the power of God and the wisdom of God.

25For the foolishness of God is wiser than man’s wisdom, and the weakness of God is stronger than man’s strength.

But it gets even stronger! You all probably already know that the most important passages in the Old Testament for Jews is the famous “Shema“, which is found in Deuteronomy 6:4-9. The Shema is a strong statement of Jewish monotheism.

Here’s the passage:

4 Hear, O Israel: The LORD our God, the LORD is one.

5 Love the LORD your God with all your heart and with all your soul and with all your strength.

6 These commandments that I give you today are to be upon your hearts.

7 Impress them on your children. Talk about them when you sit at home and when you walk along the road, when you lie down and when you get up.

8 Tie them as symbols on your hands and bind them on your foreheads.

9 Write them on the doorframes of your houses and on your gates.

So how does Paul fit Jesus in with this strong statement of Jewish monotheism?

Paul alludes to the Shema in 1 Corinthians 8:4-6.

4So then, about eating food sacrificed to idols: We know that an idol is nothing at all in the world and that there is no God but one.

5For even if there are so-called gods, whether in heaven or on earth (as indeed there are many “gods” and many “lords”),

6yet for us there is but one God, the Father, from whom all things came and for whom we live; and there is but one Lord, Jesus Christ, through whom all things came and through whom we live.

Holy mackerel! How did that get in there? Paul is splitting the roles of God in the the Shema and identifying Jesus in one of the divine roles! Jesus is not an ordinary man. That passage “through whom all things came” foreshadows John identifying Jesus as “the Word of God”, which “became flesh and dwelt among us”. Holy snark – did you guys know that was all in here so early?

The date for 1 Corinthians is 55 AD. It should be noted that skeptical scholars like James Crossley accept these passages, and you can check it out in the debate audio yourself.

Philippians

Check out Philippians 2:5-11.

5Your attitude should be the same as that of Christ Jesus:

6Who, being in very nature God, did not consider equality with God something to be grasped,

7but made himself nothing, taking the very nature of a servant, being made in human likeness.

8And being found in appearance as a man, he humbled himself and became obedient to death— even death on a cross!

9Therefore God exalted him to the highest place and gave him the name that is above every name,

10that at the name of Jesus every knee should bow, in heaven and on earth and under the earth,

11and every tongue confess that Jesus Christ is Lord, to the glory of God the Father.

The date for Philippians is 60-61 AD. Still within the lifetime of the eyewitnesses, and written by an eyewitness who was in contact with the other eyewitnesses, like Peter and James, whom Paul spoke with numerous times on his journeys to Jerusalem.

Mark’s gospel

Mark’s gospel is the earliest and atheists like James Crossley date it to less than 40 AD, which is 10 years after the death of Jesus at most. When you read the gospel of Mark, you are getting the earliest and best information available about the historical Jesus, along with Paul’s epistles. So what does Mark say about Jesus? Is Jesus just a man, or is he something more?

Check out Mark 12:1-9:

1He then began to speak to them in parables: “A man planted a vineyard. He put a wall around it, dug a pit for the winepress and built a watchtower. Then he rented the vineyard to some farmers and went away on a journey.

2At harvest time he sent a servant to the tenants to collect from them some of the fruit of the vineyard.

3But they seized him, beat him and sent him away empty-handed.

4Then he sent another servant to them; they struck this man on the head and treated him shamefully.

5He sent still another, and that one they killed. He sent many others; some of them they beat, others they killed.

6“He had one left to send, a son, whom he loved. He sent him last of all, saying, ‘They will respect my son.’

7“But the tenants said to one another, ‘This is the heir. Come, let’s kill him, and the inheritance will be ours.’

8So they took him and killed him, and threw him out of the vineyard.

9“What then will the owner of the vineyard do? He will come and kill those tenants and give the vineyard to others.

And Mark 13:32, talking about the date of the final judgment.

32“No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father.

And again, this passage is establishing a hierarchy such that Jesus is being exalted above all men and the angels, too. And the passage is embarrassing to the early church, because it makes Jesus look ignorant of something, so they would not have made this passage up. Jesus is not an ordinary man, he is above the angels – God’s unique Son.

The “Q” source for Matthew and Luke

Here’s Matthew 11:27, which is echoed in Luke 10:22:

27“All things have been committed to me by my Father. No one knows the Son except the Father, and no one knows the Father except the Son and those to whom the Son chooses to reveal him.

22“All things have been committed to me by my Father. No one knows who the Son is except the Father, and no one knows who the Father is except the Son and those to whom the Son chooses to reveal him.”

Since this passage is in both of Matthew and Luke, but not in Mark, scholars believe that it is in the earlier “Q” source used by both Matthew and Luke. Q predates both Matthew and Luke, and so it is also fairly early (maybe 67-68), although not as early as Mark and Paul. Bill Craig writes that this passage is also embarrassing because it says that no one knows Jesus.

Study: belief in free will linked to ability to behave morally and to help others

A while back I finished reading “God’s Crime Scene”, the new book by J. Warner Wallace. I wanted to post something about some studies he mentioned in Chapter 6, on free will. This is one of the places where he found evidence in a surprising area.

Wallace says that free will makes more sense if theism is true, because we have non-material souls that interact with our bodies, but are not causally determined by them. On atheism, only matter exists, and you can’t get free will (or consciousness) from matter. So atheists like Sam Harris and Alex Rosenberg, for example, deny free will, because they are materialists and atheists.

Anyway, here’s what he writes on p. 256:

In 2008, researchers from the University of Minnesota and the University of British Columbia conducted experiments highlighting the relationship between a belief in determinism and immoral behavior. They found students who were exposed to deterministic literature prior to taking a test were more likely to cheat on the test than students who were not exposed to literature advocating determinism. The researchers concluded those who deny free will are more inclined to believe their efforts to act morally are futile and are, therefore, less likely to do so.

In addition, a study conducted by researchers from Florida State University and the University of Kentucky found participants who were exposed to deterministic literature were more likely to act aggressively and less likely to be helpful toward others.” Even determinist Michael Gazzaniga conceded: “It seems that not only do we believe we control our actions, but it is good for everyone to believe it.”” The existence of free will is a common characteristic of our experience, and when we deny we have this sort of free agency, there are detrimental consequences.

I decided to look up these studies.

Here’s the abstract for first study: (2008)

Does moral behavior draw on a belief in free will? Two experiments examined whether inducing participants to believe that human behavior is predetermined would encourage cheating. In Experiment 1, participants read either text that encouraged a belief in determinism (i.e., that portrayed behavior as the consequence of environmental and genetic factors) or neutral text. Exposure to the deterministic message increased cheating on a task in which participants could passively allow a flawed computer program to reveal answers to mathematical problems that they had been instructed to solve themselves. Moreover, increased cheating behavior was mediated by decreased belief in free will. In Experiment 2, participants who read deterministic statements cheated by overpaying themselves for performance on a cognitive task; participants who read statements endorsing free will did not. These findings suggest that the debate over free will has societal, as well as scientific and theoretical, implications.

And the abstract for the second study: (2009)

Laypersons’ belief in free will may foster a sense of thoughtful reflection and willingness to exert energy, thereby promoting helpfulness and reducing aggression, and so disbelief in free will may make behavior more reliant on selfish, automatic impulses and therefore less socially desirable. Three studies tested the hypothesis that disbelief in free will would be linked with decreased helping and increased aggression. In Experiment 1, induced disbelief in free will reduced willingness to help others. Experiment 2 showed that chronic disbelief in free will was associated with reduced helping behavior. In Experiment 3, participants induced disbelief in free will caused participants to act more aggressively than others. Although the findings do not speak to the existence of free will, the current results suggest that disbelief in free will reduces helping and increases aggression.

So what to make of this?

If you’re an atheist, then you are a physical object. And like every other physical object in the universe, your behavior is determined by genetic programming (if you’re alive) and external inputs. Material objects do not have the ability to make free choices, including moral choices.

Here’s prominent atheist Jerry Coyne’s editorial in USA Today to explain why atheists can’t ground free will.

Excerpt:

And that’s what neurobiology is telling us: Our brains are simply meat computers that, like real computers, are programmed by our genes and experiences to convert an array of inputs into a predetermined output. Recent experiments involving brain scans show that when a subject “decides” to push a button on the left or right side of a computer, the choice can be predicted by brain activity at least seven seconds before the subject is consciously aware of having made it. (These studies use crude imaging techniques based on blood flow, and I suspect that future understanding of the brain will allow us to predict many of our decisions far earlier than seven seconds in advance.) “Decisions” made like that aren’t conscious ones. And if our choices are unconscious, with some determined well before the moment we think we’ve made them, then we don’t have free will in any meaningful sense.

Atheist William Provine says atheists have no free will, no moral accountability and no moral significance:

Let me summarize my views on what modern evolutionary biology tells us loud and clear — and these are basically Darwin’s views. There are no gods, no purposes, and no goal-directed forces of any kind. There is no life after death. When I die, I am absolutely certain that I am going to be dead. That’s the end of me. There is no ultimate foundation for ethics, no ultimate meaning in life, and no free will for humans, either.

If you don’t have free will, then you can’t make moral choices, and you can’t be held morally responsible. No free will means no morality. Can you imagine trying to get into any sort of enterprise with someone who has this view of moral choices? A marriage, or a business arrangement, etc? It would be crazy to expect them to behave morally, when they don’t even think that moral choices is possible. It just excuses all sorts of bad behavior, because no one is responsible for choosing to do the right thing.

Believers in materialism are going to struggle with prescriptive morality, including self-sacrificial care and concern for others. Their worldview undermines the rationality of the moral point of view. You might find atheists acting morally for their own purposes, but their worldview doesn’t rationally ground it. This is a big problem for people who can see objective morality woven into the universe – and themselves – because they have the awareness of objective right and wrong.

Choosing to do the right thing

I think what atheists like to say is “I can be moral, too”. That’s not interesting. What is interesting is whether it is rational for you to be moral when doing the right thing sets you back. When I look at the adultery of Dawkins, the polyamory of Carrier, the divorces of Shermer and Atkins, etc. I am not seeing anything that really wows me about their ability to do the right thing when it was hard for them to do it. They all deny free will of course, and think that trying to resist temptation is a waste of time.

Wallace explains how the awareness of free will and moral choices caused him to turn away from atheism, in this blog post.

He writes:

As an atheist, I chose to cling to naturalism, in spite of the fact that I lived each day as though I was capable of using my mind to make moral choices based on more than my own opinion. In addition, I sought meaning and purpose beyond my own hedonistic preferences, as though meaning was to be discovered, rather than created. I called myself a naturalist while embracing three characteristics of reality that simply cannot be explained by naturalism. As a Christian, I’m now able to acknowledge the “grounding” for these features of reality. My philosophical worldview is consistent with my practical experience of the world.

I think atheists who want to be honest about their own experience of first-person consciousness, free will, moral realism, etc. will do well to just accept that theism rationally grounds all of these things, and so you should accept theism. Theism is real. If you like morality, and want to be a virtuous person, then you should accept theism.
