John Lennox and William Lane Craig respond to Stephen Hawking

9 Comments

Theoretical physicist Stephen Hawking is in the news again theorizing about untestable speculations. He thinks that physical laws, (which are just descriptions of the way matter operates), can actually bring the entire space-time universe into being. Specifically, he thinks that the law of gravity can create matter out of nothing.

Here’s John Lennox of Oxford University responding to Stephen Hawking.

Excerpt:

There’s no denying that Stephen Hawking is intellectually bold as well as physically heroic. And in his latest book, the renowned physicist mounts an audacious challenge to the traditional religious belief in the divine creation of the universe.

According to Hawking, the laws of physics, not the will of God, provide the real explanation as to how life on Earth came into being. The Big Bang, he argues, was the inevitable consequence of these laws ‘because there is a law such as gravity, the universe can and will create itself from nothing.’

Unfortunately, while Hawking’s argument is being hailed as controversial and ground-breaking, it is hardly new.

For years, other scientists have made similar claims, maintaining that the awesome, sophisticated creativity of the world around us can be interpreted solely by reference to physical laws such as gravity.

It is a simplistic approach, yet in our secular age it is one that seems to have resonance with a sceptical public.

But, as both a scientist and a Christian, I would say that Hawking’s claim is misguided. He asks us to choose between God and the laws of physics, as if they were necessarily in mutual conflict.

But contrary to what Hawking claims, physical laws can never provide a complete explanation of the universe. Laws themselves do not create anything, they are merely a description of what happens under certain conditions.

What Hawking appears to have done is to confuse law with agency. His call on us to choose between God and physics is a bit like someone demanding that we choose between aeronautical engineer Sir Frank Whittle and the laws of physics to explain the jet engine.

That is a confusion of category. The laws of physics can explain how the jet engine works, but someone had to build the thing, put in the fuel and start it up. The jet could not have been created without the laws of physics on their own  –  but the task of development and creation needed the genius of Whittle as its agent.

Similarly, the laws of physics could never have actually built the universe. Some agency must have been involved.

To use a simple analogy, Isaac Newton’s laws of motion in themselves never sent a snooker ball racing across the green baize. That can only be done by people using a snooker cue and the actions of their own arms.

Hawking’s argument appears to me even more illogical when he says the existence of gravity means the creation of the universe was inevitable. But how did gravity exist in the first place? Who put it there? And what was the creative force behind its birth?

And here is an MP3 file with Bill Craig’s response. Craig thinks that Hawking’s new book is basically the same as his previous book where he introduced the idea that his quantum gravity theory can explain the creation of the universe out of nothing, and then the multiverse to explain the fine-tuning.

UPDATE: I added a new post with Henry F. Schafer’s take on Hawking’s no-boundary proposal.

My thoughts

The law of gravity is just a mathematical equation that describes nature. Gravity is part of the natural world – it is a force of attraction between material objects. How can this force exist causally prior to the creation of all matter at t=0? It cannot. Self-creation is a self-refuting contradiction. For a thing to create itself, it would have to exist before it existed.

Maybe that passes for intelligent thought in the world of atheistic speculations, but not in the world of experimental science, which provides strong evidence for a Creation out of nothing, and a Design plan for the universe. Maybe this is just like Dawkins avoiding a debate with William Lane Craig – it’s not about seeking truth, it’s about book sales. It’s not like Hawking is going to subject his speculations to a public debate.

Commentary

Responding to religious pluralism

13 Comments

Recently, I had posted a debate from the Unbelievable radio show, which is broadcast in the UK. The topic of the debate was whether India should pass an anti-conversion law to prevent Christians from trying to convert people to Christianity. Basically, many Hindus in India want Christians to adopt the Hindu notions of polytheism and religious pluralism. They want Christians to accept that Jesus is one incarnation of the divine among many, and they want to outlaw the Christian practice of using speech to convince people to become Christians.

You can listen to the debate here in my original post.

But I wanted to highlight another debate that occurred in the comments of this blog, between me and a Hindu reader, who challenged me for being intolerant because I said that Hinduism was false. (Just briefly, understand that half my family is Muslim, and the other half is 90% Hindu – I am a visible minority, and my parents are first generation immigrants who started out with nothing).

His initial comment is here.

Guys, all religions teach the same things. Its how each religion is interpreted that makes it different. If you follow any religion persistently, it will lead you to a peaceful and happy life.

[…]If one feels happy following Christian rituals, he may follow Christianity; if he feels happy following Hindu rituals, he is good to a Hindu. It all depends on what makes sense to the person. Enforcing or luring someone to another religion is wrong…It should be a personal choice. And no one should oppose a conversion made by personal choice.

[…]To say that someone’s God or method of worship is false or not real is absolute rubbish according to me.

[…]If one says that other’s God or religion is false, he/she is not tolerating the other’s beliefs. And its immoral. Such things lead to religious conflicts.

[…]I believe in Jesus and so in my religion which is Hinduism.

[…]Why convert when a human being’s main aim is to be happy? Every religion has scriptures that tell how to become happy and attain heaven/liberation.

[…]Everyone loves his/her religion. They would not want to hear anything bad about it.

And I replied:

Our view as Christians is that the purpose of religion is not to live a happy life and to be “good”. Our view is that we want to believe what is true and to know God as God really is. We believe that God is a person, with a real personality – likes and dislikes.

What you’re proposing is a Hindu approach to religion, except with Christian symbols and rituals. But Christians don’t care about symbols and rituals much. We are more interested in history, science and propositional logic. We treat religion like… any other area of knowledge. First we discover the truth, then we act on it.

Additionally, you have a Hindu approach to conversion, and you are trying to force that on Christians. You can keep your Hindu approach to yourself, and tolerate the fact that we have a different approach to conversion.

[…]You’re not in a position to know what Christianity teaches, or what Jesus believes, since you haven’t looked into these things at all. You know Hinduism. And you are projecting Hinduism onto other religions. But Hinduism is totally different than Christianity. They conflict in many areas, like cosmology and history. We believe that the universe had a beginning, you think it’s eternal. And science can arbitrate that claim. We are willing to change our beliefs to be in line with what we can test in the external world, using the laws of logic, and the study of science and history.

[…]You write “To say that someone’s God or method of worship is false or not real is absolute rubbish according to me.”, yet you think that Christianity is false, and not real. But I am actually not offended by that at all. You are welcome to think I am wrong. I don’t mind, this is the way that the game plays. Only one of us can be right, and if you were right, I would have to switch over to your view and that would be fine with me.

[…]You write “Everyone loves his/her religion. They would not want to hear anything bad about it.” No that’s your view. You identify Hindusim with India and patriotism and your people and culture. I don’t identify Christianity with anything except truth. I like it because it’s true. And that the only reason I like it.

[…]When I say that Hinduism is false, I am not “talking bad about your religion” any more than I am talking bad about the view that 2 + 2 = 5, when I say that 2 + 2 = 4. It’s not talking bad about an idea to say it is false.

And then he replied:

Do you believe that people who worship idols are devilish or all religions except Christianity are false? If yes then explain me with proper scientific reasoning and provide me a proof in the recent decades that logically explains the above two statements. You need to prove me that what you believe is experimented by scientists and proven by technology.

[…]I believe in all Gods no matter what religion because God is One. For me and this generation of educated Indians, we believe in tolerance and respect for all religions. We believe in co-operating with each other and not pointing flaws in others beliefs until its proven scientifically and attested by scientific authority. And we believe that people’s belief be respected!

Then I replied:

The current best theory of the origin of the universe is called the big bang theory. It states that all the matter, energy, as well as time and space and time, came into being from nothing. It is backed by experimental data from red-shift measurements, cosmic microwave background radiation measurements, and light element abundance measurements, etc. The theory states that the universe began 14.7 billion years ago. Additionally, the universe will not recollapse because measurements of mass density from Maxima and Boomerang show that the universe will expand forever.

The big 3 monotheistic religions agree with the universe coming into being from nothing. Unfortunately, other religions think that the universe is eternal, such as Mormonism and Hinduism. On that basis, I reject Hinduism, which requires that the universe be eternal.

“I believe in all Gods no matter what religion because God is One.” That view (pantheism/polytheism) is called Hinduism. You are a Hindu. Christianity (monotheism) is mutually exclusive with Hinduism, because the teachings are in conflict, (as with the example of cosmology). As a Hindu, you therefore think that Christianity is false. On your definition, you don’t “tolerate” Christianity – you think it’s false. You don’t “respect” Christianity, because you want to force your view (Hinduism) and your view of conversion (don’t tell other people their religion is false) on Christians.

[…]Note: I am ok with you saying that I am wrong and that Christianity is false.

And then we sort of wound things down from there.

Anyway, the point of this exchange is most people in most religions think that the point of religion is to be happy, to have a sense of community and to get along with everyone by never talking about whether religious claims about the external world are true or false. But that view of the purpose of religion is not the Christian view. On the Christian view, the goal is to seek the truth. And part of Christian practice is to defend Christianity in public, and trying to convince other people that Christianity is true.

So, I think that Christians need to be a bit tougher, and recognize when someone who is not a Christian is trying to get them to accept that the purpose of religion is not to seek the truth. That’s their view. That’s not our view. It doesn’t make any sense for someone to say that I am evil for thinking they are wrong, when they are thinking that I am wrong. I think a better way forward is to allow other people to disagree with you, but to keep the disagreement focused on arguments and evidence.

And just because you disagree with someone else, it doesn’t mean you have to be mean to them. In my office, I am friends with Hindus, Muslims, atheists and Jews. We try to outdo one another in good deeds to make our religions look good! And when we debate which religion is true, we use arguments and evidence to attack and defend. What I’ve found is that you get a much stronger friendship when you are comfortable being yourself. I keep telling my co-workers – it’s OK to disagree.

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.
