How the progress of science strengthened the kalam cosmological argument

33 Comments

This is the first of a two-part series. Part two is here.

The kalam cosmological argument

The argument goes like this:

  1. Whatever begins to exist requires a cause
  2. The universe began to exist
  3. Therefore, the universe requires a cause.

The most important thing for you to realize is that nothing can be sustained in a debate unless it can be phrased as a valid argument according the rules of inference. All of Craig’s arguments can be broken down into logical propositions that use the standard laws of logical reasoning in order to force their conclusions deductively, so long as the premises are true.

Proving the premises

Can the atheist deny that either or both of these premises are true?

  1. “Whatever begins to exist requires a cause”
    If the atheist denies this premise, then they are denying a fundamental law of natural science, namely, that matter can neither be created or destroyed. That is natural law.
  2. “The universe began to exist”
    The universe came into being. If the atheist denies this they are denying the state of the art in modern cosmology.

Common objections

First, quantum mechanics is not going to save the atheist here. In QM, virtual particles come into being in a vacuum. The vacuum is sparked by a scientist. The particles exist for a period of time inversely proportional to their mass. But in the case of the big bang, there is no vacuum – there’s nothing. There is no scientist – there’s nothing. And the universe is far too massive to last 14 billion years as a virtual particle.

Secondly, atheists will say that the big bang is speculative physics that could change at any moment. But the trend is in favor of an absolute beginning out of nothing. We have had a string of solid, recent scientific discoveries that support the idea that the universe came into existence at some point in the finite past, as follows:

  • Einstein’s theory of general relativity, and the scientific confirmation of its accuracy
  • measurements of the cosmic microwave background radiation
  • red-shifting of light from galaxies moving away from us
  • radioactive element abundance predictions (from supernovae)
  • helium/hydrogen abundance predictions (nuclear fusion)
  • star formation and stellar lifecycle theories
  • the second law of thermodynamics

So, insofar as atheists question these discoveries and the origin of the entire physical universe out of nothing, they are opposing the progress of science.

What came into being at the moment of creation?

You need to understand that the big bang theory states that space, time and matter were all created at the moment of creation.

  1. There was no space causally prior to the universe beginning to exist
  2. There was no time causally prior to the universe beginning to exist
  3. There was no matter causally prior to the universe beginning to exist

All of these things began to exist at the first moment.

What can we infer about the cause?

So, space, time, and matter began to exist. What could have caused them to begin to exist?

  1. Whatever causes the universe to appear is not inside of space, because there was no space causally prior to the creation event. The cause must therefore be non-physical, because physical things exist in space.
  2. Whatever causes the universe to appear is not bound by time (temporal). It never began to exist. There was no passage of time causally prior to the big bang, so the cause of the universe did not come into being. The cause existed eternally.
  3. And the cause is not material. All the matter in the universe came into being at the first moment. Whatever caused the universe to begin to exist cannot have been matter, because there was no matter causally prior to the big bang.

So what could the cause be? Craig notes that we are only familiar with two kinds of non-material realities:

  1. Abstract objects, like numbers, sets and mathematical relations
  2. Minds, like your own mind

Now, abstract objects don’t cause of any effects in nature. But we are very familiar with the causal capabilities of our own minds – just raise your own arm and see! So, by process of elimination, we are left with a mind as the cause of the universe. As Sherlock Holmes says, “When you have eliminated the impossible, whatever remains, however improbable, must be the truth.”

This cause created the entire physical universe. The cause of this event is therefore supernatural, because it brings nature into being and is not inside of nature itself. The cause of the universe violates the law of conservation of matter is therefore performing a miracle.

Responding to alternative naturalistic cosmologies

In this published research paper from the journal Astrophysics and Space Science, William Lane Craig responds to the several naturalistic attempts to evade the implications of the kalam argument. I will list each one by name and explain the main problem with each. I highly recommend you read the paper and become conversant with the arguments and evidences.

  1. The steady-state model: disproved by recent empirical observations of radio galaxy distributions, as well as red-shifting of light from distant galaxies moving away from us at increasing speeds
  2. The oscillating model: disproved in 1998 by more empirical measurements of mass density which showed that the universe would expand forever, and never collapse (was named Discovery of the Year)
  3. The vacuum fluctuation model: the theory allows for universes to spawn at every point in space and coalesce into one extremely old universe, which contradictions observations of our much younger universe
  4. The chaotic inflationary model: does not avoid the need for an absolute beginning in the finite past
  5. The quantum gravity model: makes use of imaginary time which cannot be mapped into a physical reality, it’s purely theoretical

Comment warning

Everybody seems to like to comment on these things without making any claims or citing any authority or evidence. So if you are leaving a comment critical of this post, then cite the part you disagree with, quote someone who agrees with you who is an authority, and link to a piece of peer-reviewed evidence. I’d like to see some observations, please. Some data. If you cannot disagree with a specific point, and cite something specific to support you, then please – don’t leave a comment. Try to keep it short. I’ll delete any comments that go over 300 words, say.

If you would like me to cite some evidence for an assertion, you can leave a comment asking a question.

Further study

A good on this topic is the debate between William Lane Craig and atheist physicist Victor Stenger, (audio here). Also, a lecture titled “Beyond the Big Bang”, was delivered at the University of Colorado at Boulder, in front of Victor Stenger and other physicists (audio here). There is a period of Q&A in which Bill must face challengers. These are both available on DVD. More Bill Craig debates are here.

Easter is a good time to learn how to defend the resurrection of Jesus

8 Comments

(This is a re-post of a previous post about ten resources for learning how to defend the resurrection of Jesus. See Free Canuckistan’s Easter post for a more spiritual perspective on Easter – he focuses on the victory of Jesus)

First, let’s briefly talk about whether the Bible supports talking about the resurrection with non-Christians.

There are lots and lots of Christians in the world, but almost none of them are comfortable talking about the resurrection with non-Christians, in a way that doesn’t use crazy Christianese language and doesn’t assume that the Bible is inerrant. But I think that this situation is wrong for three reasons.

First, Jesus says that his resurrection is a sign so that people will believe in his other theological claims.

Matthew 12:38-40:

38Then some of the Pharisees and teachers of the law said to him, “Teacher, we want to see a miraculous sign from you.”

39He answered, “A wicked and adulterous generation asks for a miraculous sign! But none will be given it except the sign of the prophet Jonah.

40For as Jonah was three days and three nights in the belly of a huge fish, so the Son of Man will be three days and three nights in the heart of the earth.

Second, Paul says that if the resurrection didn’t happen then we are all wasting our time with Christianity.

1 Corinthians 15:13-19:

13If there is no resurrection of the dead, then not even Christ has been raised.

14And if Christ has not been raised, our preaching is useless and so is your faith.

15More than that, we are then found to be false witnesses about God, for we have testified about God that he raised Christ from the dead. But he did not raise him if in fact the dead are not raised.

16For if the dead are not raised, then Christ has not been raised either.

17And if Christ has not been raised, your faith is futile; you are still in your sins.

18Then those also who have fallen asleep in Christ are lost.

19If only for this life we have hope in Christ, we are to be pitied more than all men.

And third, Peter uses the resurrection as evidence in his evangelistic efforts.

Acts 2:22-24, 29-33, 36:

22“Men of Israel, listen to this: Jesus of Nazareth was a man accredited by God to you by miracles, wonders and signs, which God did among you through him, as you yourselves know.

23This man was handed over to you by God’s set purpose and foreknowledge; and you, with the help of wicked men, put him to death by nailing him to the cross.

24But God raised him from the dead, freeing him from the agony of death, because it was impossible for death to keep its hold on him.

29“Brothers, I can tell you confidently that the patriarch David died and was buried, and his tomb is here to this day.

30But he was a prophet and knew that God had promised him on oath that he would place one of his descendants on his throne.

31Seeing what was ahead, he spoke of the resurrection of the Christ, that he was not abandoned to the grave, nor did his body see decay.

32God has raised this Jesus to life, and we are all witnesses of the fact.

33Exalted to the right hand of God, he has received from the Father the promised Holy Spirit and has poured out what you now see and hear.

36“Therefore let all Israel be assured of this: God has made this Jesus, whom you crucified, both Lord and Christ.”

So, how can you do what Jesus, Paul and Peter do with your non-Christian friends?

You can do it, too – and you must

It’s true that non-Christians don’t like to hear that they will go to Hell unless they have a relationship with Jesus. And do you know why they think that? Because they think that sin and Hell are just your personal opinions. Not-very-nice opinions. Opinions that they can ignore because it’s just your personal preference that you were raised in. They think that religion is like Santa Claus and the Tooth Fairy – myths designed to make people feel good about themselves.

Just think for a minute what they must think of your blind-faith pronouncement that they are going to Hell unless they “believe in Jesus” (whatever that means to a non-Christian). How would you like to hear someone tell you that you are going to Hell for not liking vanilla ice cream? You’d think they were crazy! And that’s what non-Christians think of you, unless… Unless what? Unless you present publicly testable arguments and evidence to show them why they should consider the claims of Jesus.

No one complains that it is “mean and divisive” if their doctor diagonoses them with cancer. Because a challenging diagnosis is not the doctor’s personal opinion – it’s true objectively. You need to make your presentation of the gospel exactly like a doctor’s diagnosis. Am I making sense here?If you are telling them the truth and you can show them publicly testable reasons and evidence, what sense does it make for them to be offended? They might as well be offended by their credit card statement or their speeding ticket.

I have Jewish friends, Hindu friends, Muslim friends, atheist friends, etc. Telling people the truth with publicly testable arguments and evidence that they can assess for themselves works. What doesn’t work is denying the reality of sin and Hell and then trying to be nice to non-Christians who are going to Hell so that they will like you. That‘s not Biblical. That’s just reinventing Christianity based on your own emotional need to be happy and to be liked by others and to feel good about yourself.

Some things to help you talk about the resurrection

The main thing to remember about talking about the resurrection in public with non-Christians is that you can’t assume that the Bible is true. Serious Christians get around this by using standard historical criteria to filter out the passages of the Bible that are most likely to be historical. A passage could be as small as 1 verse or it could be several verses. Some of the criteria would be things like: 1) how early after the events was the passage written? 2) in how many places does it appear? 3) Are the places where it appears independent from one another (e.g. – Mark and Paul), 4) does it embarass the author in some way? Using these criteria, historians can extract a bare minimum set of facts about Jesus.

Once you establish these minimal facts, you argue that the best explanation of the facts is that God raised Jesus from the dead. Your opponent either has to disprove one of your minimal facts, or he has to propose an alternative explanation of those minimal facts that explains the data better.

Usually, the only point of disagreement is whether the tomb was empty. Most atheists will give you the crucifixion, the burial, the post-mortem appearances, and the early belief in the bodily resurrection of Jesus in the early church.

Commentary

Neil Simpson on the minimal facts case for the resurrection

2 Comments

From Neil Simpson’s 4Simpsons blog.

Excerpt:

This is a summary of the “minimal facts” approach, which points to commonly held historical facts as evidence for the resurrection of Jesus and the truth of Christianity.  Nearly 100% of historical scholars from 1975 – present agree with the following statements:

  • Jesus really lived and was killed on a Roman cross.
  • Jesus’ disciples believed He appeared to them.
  • Jesus’ brother, James, went from being a pre-crucifixion skeptic to a post-crucificion church leader.
  • The Apostle Paul believed Jesus appeared to him and he wrote most of the books attributed to him, including Romans, I & II Corinthians, Philemon and others.

75% of the same scholars agree that the tomb was empty.

I submit that the physical resurrection of Jesus best accounts for these facts.

He’s got a link to Mary Jo Sharp’s slide show on the minimal facts approach.

My best comprehensive post on the minimal facts case for ressurection is here: Ten resources to help you talk to non-Christians about the resurrection of Jesus.

Come on, folks. We all need to be able to talk about the resurrection as much as we can talk about our favorite sports team or our favorite celebrities/artists. I’m sure that Jesus likes it when we can talk about his resurrection in public with other people – especially non-Christians. The minimal facts approach is the best way to do that!

Be his friend – talk about his resurrection. Intelligently.
