The cosmological argument and the new BGV theorem

5 Comments

Did you all read my summary of the excellent debate between William Lane Craig and Peter Millican? That was probably the best debate I have seen in since 2005. William Lane Craig presented the arguments for theism, including his standard Kalam cosmological argument which asserts that the universe had a beginning. The atheist, Peter Millican, raised several objections to the notion of a beginning to the universe. But Craig was able to establish the beginning of the universe by appealing to something called the Borde-Guth-Vilenkin theorem. This theorem is new – but it is worth learning about.

First, let’s review Craig’s cosmological argument:

A1) The origin of the universe

  1. The universe began to exist.
  2. If the universe began to exist, then the universe has a transcendent cause.
  3. The universe has a transcendent cause.

The origin of the universe is confirmed by philosophical arguments and scientific evidence.

There cannot be an actual infinite number of past events, because mathematical operations like subtraction and division cannot be applied to actual infinities.

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.

Even speculative alternative cosmologies do not escape the need for a beginning.

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.

So he appealed to the Bord-Guth-Vilenkin theorem right from the start in order to guarantee a space-time boundary in the past – i.e., a beginning of the universe, which is his premise 1.

Ok, now let’s take a look at some videos on this theorem.

Part 1:

Part 2:

Millican tried to argue that there was a way to get a beginning in an eternal universe if the universe was contracting. I’m guessing he means that the new universe would begin to exist within some outside hyper-universe.

But Craig had a response:

Further study

If you would like to read a nice LONG article about Craig’s cosmological argument, just check this post I wrote a while back. And it even contains a nice peer-reviewed paper that Craig wrote for an Astrophysics journal – and the abstract is online on Springer! Now put your Evil Hat on and think with me – think of the fun you could have by sending that paper to all your atheist friends. Send them the abstract on Springer, and send them the full text of the article. Then send them the link to my summary of the Craig-Millican debate which has the audio. If that doesn’t rehabiliate God’s reputation and honor in their eyes, then nothing will. At the very least, they should be ready to accept that atheism is not as well supported by science, which is exactly the way that God intended things to be.

What does the Bible say in Psalm 19:1-6:

 1 The heavens declare the glory of God;
the skies proclaim the work of his hands.
2 Day after day they pour forth speech;
night after night they reveal knowledge.
3 They have no speech, they use no words;
no sound is heard from them.
4 Yet their voice goes out into all the earth,
their words to the ends of the world.
In the heavens God has pitched a tent for the sun.
5 It is like a bridegroom coming out of his chamber,
like a champion rejoicing to run his course.
6 It rises at one end of the heavens
and makes its circuit to the other;
nothing is deprived of its warmth.

And in Romans 1:20:

20 For 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 people are without excuse.

And in Hebrews 11:3:

 3 By faith we understand that the universe was formed at God’s command, so that what is seen was not made out of what was visible.

Indeed. And it’s our job to make his glory know to the unbeliever – using good science.

Hugh Ross debates Lewis Wolpert on scientific evidence for a Creator

Leave a comment

From the 2012 Unbelievable UK conference, Peter Byrom (BirdieUpon) reports on a great debate on science and Christianity.

Excerpt:

I had the great pleasure yesterday of attending the debate “Does the universe show evidence for a creator?” at Imperial College, London. Arguing in the affirmative was astrophysicist Hugh Ross of Reasons To Believe,  a science-faith think tank from the USA; arguing the negative was Lewis Wolpert, Emeritus Professor of biology and British Humanist.

[…]But, onto the debate itself! A good turn-out. The lecture theatre was packed. It was hosted by Imperial College’s Christian Union, but a decent number of atheists and sceptics showed up too – which is quite something given that AC Grayling was giving a lecture in the next room (he passed by me earlier as I was editing my latest Dawkins-critical video on my laptop… I don’t think he noticed)!

This is where it gets interesting. Hugh Ross went first, and outlined for 20 minutes his Creation Model, arguing that the Bible – and only the Bible – contains consistent, scientifically accurate predictions about the cosmos, the empirical data for which is only being discovered recently in the modern age. His case is essentially that the more we discover about the universe, the more the evidence for design and a transcendent creator piles up and confirms what the Bible has been telling us for the past thousands of years. Of particular note were passages from Jeremiah and Romans, which Hugh claims tell us about the expansion of the universe and the law of entropy. Alongside we have the opening of the Bible, that in the beginning God created the heavens and the Earth – the Big Bang is this beginning. When this was discovered, a great many scientists were reluctant to accept it, fearing that an absolute beginning of space and time gave too much leverage to those who believe in theistic creation.

It was fascinating also to hear Hugh cite an article written by atheist physicists called “Disturbing Implications of the Cosmological Constant”. In this article, its atheist authors were forced to concede that this particular cosmological constant left them no choice but to invoke a transcendent causal agent. Their solution? To “do a Daniel Dennett”: conclude that this cosmological constant must, therefore, surely be false (!)

Melanie Phillips: The real intolerance comes from secularism

9 Comments

Here’s a great post by conservative British journalist Melanie Phillips. (I think she is Jewish, by the way)

Excerpt:

I have a rather different take on this great division of our age. My view is that while we may be in a post-biblical — and post-moral — age, we have not disposed of belief. Far from it. We have just changed what we believe in. Our society may have junked the Judaeo-Christian foundations of the West for secularism. But this has given rise to a set of other religions. Secular religions. Anti-religion religions.

These are also based on a set of dogmas. They proselytise. They involve faith. But unlike the Judaeo-Christian thinking they usurp, these secular anti-religions suspend truth and reason. What’s more, I would say that it was the Judaic foundations of the West which, far from denying reason, gave the world both reason and science in the first place.

God has been pronounced dead, and in his place have come man-made ideologies — in which people worship not a divine presence but an idea.

These ideas, which brook no dissent, give rise inescapably to intolerance and indeed to tyranny. Indeed, they are far more tyrannical in their effect than the God of the Hebrew Bible who gets such a bad press for being so authoritarian. In fact, he has a truly terrible time getting his way. His people are always complaining, refusing to do what he tells them, blaming him for everything and always, always arguing with him. But ideologies which represent the will of man bend everything to the governing idea, which cannot be gainsaid. There can be no argument with them.

Rather than being rational, I suggest these are irrational; not tolerant at all, but deeply illiberal; not open to other ideas, but as dogmatic as any medieval pope. Indeed, these atheistic ideologies are reminiscent not just of religion but of medieval persecutions, witch-hunts and inquisitions.

Let me illustrate all this with an anecdote. After a debate in which he took part some time ago, I pressed Richard Dawkins on his belief that the origin of all matter was most likely to have been an entirely spontaneous event — which meant he therefore surely believed that something could be created out of nothing. Since this ran counter to the scientific principle of verifiable evidence which he tells us should govern all our thinking, this itself seemed to be precisely the kind of irrationality which he scorns.

In reply, he acknowledged that I had a point but said that the alternative explanation — God — was more incredible. But then he remarked that he was not necessarily averse to the idea that life on Earth had been created by a governing intelligence — provided, however, that such an intelligence had arrived on Earth from another planet. Leaving aside the question of how that extra-terrestrial intelligence had itself been created in the first place, I put it to him that he appeared to be saying that “little green men” provided a more plausible explanation for the origin of life on Earth than God. Strangely, he didn’t react to this well at all.

However, Dawkins is not the first scientist to have suggested this. It is a theory which was put forward by no less than Professor Francis Crick, one of the discoverers of DNA.

A committed atheist, Francis Crick found it impossible to believe that DNA could have been the product of evolution. In 1973, Crick and the chemist Leslie Orgel published a paper in the journal Icarus suggesting that life may have arrived on Earth through “directed panspermia”. According to this theory, micro-organisms were supposed to have travelled in the head of an unmanned spaceship sent to Earth by a higher civilisation which had developed elsewhere some billions of years ago. The spaceship was unmanned so that its range would be as great as possible. Life started here when these organisms were dropped into the primitive ocean and began to multiply. Subsequently, Crick abandoned this theory and returned to the idea of the spontaneous origin of life from purely natural mechanisms.

How can someone so committed to reason be so irrational as to entertain such a fantasy?

What I found great about this article is that even though Melanie Phillips is a popular columnist, she actually deals with evidence when talking about God. So often on Christian blogs, you can read tons of posts that are really just inside baseball for Christians. It’s just pablum or lists of todos. The right way to talk about God is by talking about the evidence. Even Melanie Phillips sees that. Why don’t we?

I think we need to be very forthright when speaking with atheists and call them out for what they are. They are the people who hate astrophysics, and despise the Big Bang cosmology. They are the believers in the unobservable, untestable multiverse. They are the believers in the unobservable, untestable aliens who seed the Earth with life. They are the believers in the as-yet-undiscovered Cambrian precursor fossils. They believe that material processes can somehow produce creatures that have free will and consciousness. They are the ones who think that right and wrong are purely arbitrary – matters of opinion that are decided one way or the other in different times and places. They are the ones who believe that when you die, you are not accountable for anything you’ve done, and nothing that you’ve done has ultimate meaning. Let’s be up front about all of that, and hold them accountable for their anti-science, anti-morality, anti-human views. And let’s hold them accountable for running away from debates with their tails between their legs – like that coward Richard Dawkins did.
