Warning: A little long and a little dense. You might need to brew a warm cup of coffee and appoint a friend to slap you in the face every 10 minutes to keep you from nodding off. This is a fuller explanation of one of the arguments for God’s existence presented last sunday that considers some possible objections and responses.
The Conversation Continues…
Chris- Have you heard of the science of fine-tuning, or Astrobiology?
Brian- Yes, of course. You’re referring to the Goldilocks enigma. Our planet is just right for complex, carbon based creatures like ourselves. For example, our planet is 93 million miles away from the sun. Much closer and the earth’s surface would be too smoldering for life; much further away and it would be too frigid.
In addition, our earth spins on its axis at 23.5 due to the gravitational pull of the moon and the sun. The earth’s tilt allows us to enjoy our seasons and keeps us from experiencing temperature that is too extreme for complex life to flourish.
Our atmosphere is made up of 21% oxygen. 15% oxygen and we would suffocate. 25% oxygen in our atmosphere and unstoppable fires would ignite continually .
There are other factors that allow life to thrive on planet earth including our place in the galaxy, Gas giants like Jupiter that protect us from Asteroids and the abundance of liquid water with all its unique properties found on planet earth .
Chris- Right. So clearly you are familiar with the finds of Astrobiology and the search for what makes planets habitable for complex life forms like Homo Sapiens.
Brian- Yes, I learned about this in my undergrad.
Chris- But the science of fine-tuning goes far beyond our distance from the sun or the abundance of liquid H20 on planet earth.
To quote Philosopher William Lane Craig:
“This fine-tuning is of two sorts. First, when the laws of nature are expressed as mathematical equations, you find appearing in them certain constants, such as the constant representing the force of gravity. These constants are not determined by the laws of nature. The laws of nature are consistent with a wide range of values for these constants….Second, in addition to these constants there are certain arbitrary quantities which are just put in as initial condition on which the laws of nature operate- for example, the amount of entropy or the balance between matter and antimatter in the universe. These constants and quantities fall into an incomprehensibly narrow range of life-permitting values.”
Let me give you some more examples of both sorts of fine-tuning. Have you read, ‘A Brief History of Time’ by Stephen Hawking?
Brian- Yes. That’s an old but famous book.
Chris- He writes, “If the rate of expansion one second after the big bang had been smaller by even one part in a hundred thousand million million, the universe would have recollapsed before it ever reached its present size” .
Basically, in the initial moments after the big bang if the universe had expanded any faster matter wouldn’t have coalesced and no life would be possible. If the universe had expanded a tiny degree slower the universe would have collapsed in on itself and no complex biological life would have been actualized in our cosmos.
In a latter work he wrote,
“If the rate of expansion one second after the big bang had been less than 1 part in 10(10) , the universe would have collapsed after a few million years. If it had been greater by one part in 10(10), the universe would be essentially empty after a few million years. In neither case would it have lasted long enough for life to develop”.
Brian- Wow.
Chris – Well, let me keep going. Consider the Strong Nuclear force that binds together Atomic Nuclei, without which life, as we know it could not have formed. If the Strong Nuclear force were altered from 0.007 to 0.008 or 0.006 no life would be possible .
If the electromagnetic force were adjusted in the slightest degree the stability of Atomic Nuclei would also be threatened and the building blocks of life would vanish .
If the strong coupling constant were slightly smaller, hydrogen would be the only element in the universe and because we are carbon based creatures that would end the beginning of us .
If the weak fine constant were a sliver of a degree smaller, no hydrogen would have formed during our universes infancy. The result would a starless universe . No sun means no sex. No sex means no people.
Or is it the other way around?
Or consider the gravitational force; if it was any stronger stars would burn up and implode far faster. Their life span would be dramatically shortened from around 10 billion years to less than 100 million years, which given current evolutionary theory (whether you accept it or not), is not long enough for complex life forms like us to emerge .
Brian- That’s amazing!
Chris- Now, imagine these cosmological constants as number keys on your cell phone. Imagine (hypothetically) that you’re dialing a 1-800 hundred number late one Friday night. How many number keys do you have to misdial to ruin your chance of connecting via phone to a friendly stranger?
Brian- Only one.
Chris- Right. One wrong key and the call doesn’t go to its intended recipient and you’re unable to have the desired conversation. When it comes to us being privileged to have this conversation only one of these various cosmological constants had to be misdialed for all complex life (as we know it) to be impossible. We would cease to exist.
1-800 numbers would be no more.
Brian- It’s unnerving to think about but fascinating at the same time.
Chris- So what is the best explanation for the fine-tuning of the Universe considering that it could have easily been different?
Brian- I think I know where you are going with this.
Chris- Right. Well, the fine-tuning of the universe is either due to chance or design. The chance hypothesis is incredible improbable. The degree of precision involved renders the cosmic lottery option obsolete.
Brian- Why? People occasionally win the lottery.
Chris- We didn’t win just win one lottery. Every fine-tuned physical constant was like winning a lottery. We won at least 12. If someone won twelve lotteries in a row you wouldn’t say, ‘lucky them’, you would think it was rigged. The Christians says, ‘guess what, the universe looks rigged because it was rigged by a designer God’.
Brian- But look, I’m not sure you can adequately assess the probability of the universe being fine-tuned for life. Either way, improbabilities happen all the time. Think of all the improbabilities inherent in us having this conversation.
What are the chances that we would live in the same part of the world, meet one another, have similar interests and both be willing to engage in this type of debate. Given the 7 billion people in this world the odds are incredibly unlikely.
But here we are. Is this the part of some divine design?
Chris- Well, actually I reckon it is but that is beside the point. The improbability of the universe being fine-tuned for life is only the first part of the mystery. The second part involves the indisputable fact that in our experience fine-tuning is always the result of a fine-tuner, or a designer.
Not only is the fine tuning of the universe improbable given the fact that things could have so easily been different , but the fine tuning also corresponds to an independent pattern that we know in our experience is the result of intelligence, design and purpose .
Brian- Okay. Our planet is habitable. Most of the universe, however, is extremely hostile to life. How can you believe this is the result of an intelligent designer?
Chris- I think that type of response is an evasion.
Brian- Why?
Chris- Imagine you are shipwrecked on an isolated Island in the South Pacific that is extremely hostile to life. The water supply is low, dangerous animals run wild, and poisonous plants litter the underbrush. In your early explorations of the Island, however, you come across a clearing with a small hut nestled in its center. You exclaim in excitement, ‘an intelligent person, with a purpose must have created this hut’. What if your fellow traveler turned to you and said, ‘How can you say that this one pocket of order and creativity on the island is designed when the rest of it is so inhabitable’? Would you give up your belief that an intelligent agent designed the hut just because the rest of the Island is hazardous to life? Of course not!
In the same way the inhospitality of the rest of the universe does not refute the fact that our planet is fine-tuned for life’. In fact, I think your objection misunderstands the fine- tuning argument. It’s not just that the earth is fine-tuned for life in an otherwise inhospitable universe (which by the way we’re not sure of, as your friends at SETI would remind you) -rather, written into the universe from its very beginning are precisely dialed constants that make life possible.
Brian- But why can’t I just say, ‘Of course, the universe is fine-tuned for life. Otherwise we wouldn’t be here notice the fact’. In fact, that approach is called the Anthropic principle.
Chris- Here is the problem: Your comment mistakes a necessary condition for a sufficient explanation of that condition.
Brian- What?
Chris- Here is a common analogy that shows the inadequacy of your response to the fine-tuning argument that was originally developed by a Canadian philosopher named John Leslie .
Imagine you’re smuggling Bibles into North Korea. You get caught at the border, the Bibles are confiscated, and false drug charges are trumped up. You are sentenced to death by the firing squad .
You are forced up against the killing wall, one hundred shoulders take aim, there is a deafening roar, your bladder empties, and you wait for it all to end. Two long seconds pass, you open your eyes, you’re still alive. One hundred trained shoulders missed from twenty feet away. You’re shocked and relieved.
You are dragged back to your cell. Your fellow prisoners whisper excitedly to you, ‘I can’t believe you’re still alive. The soldiers must have had orders to miss you’.
You respond, ‘What are you talking about ‘ordered to miss me’? Of course, they missed me. If the soldiers hadn’t missed I wouldn’t be here to comment about it.
The above ‘lucky’ man has mistaken a necessary condition for his survival (the soldiers missing) for a sufficient explanation of that condition.
Brian- I think I’ve got it but can you give me another example?
Chris- Okay. Imagine you take off in a commercial airliner when four thousand feet off the ground you experience total engine failure. Your plane is hurtling towards the hard, unyielding earth at hundreds of miles per hour without the aid of landing gear. Statistically you know that given your current situation the chances of everyone on your plane surviving are astronomical.
Now, lets pretend that not only does everyone survive the crash but the plane barely has a scratch. One of your fellow passengers glances in your direction and with a pronounced look of relief queries, ‘Why did we survive this wreck with such minimal damage?’
Could you imagine responding, ‘Why is not important. What matters is we survived the wreck which is why we are here discussing it’.
Not only does your response lack a certain amount of curiosity and creativity it also mistakes a necessary condition for a sufficient explanation of the condition.
In order for you to have the aforementioned conversation with your fellow passenger you had to survive (necessary condition) but that doesn’t explain why you survived (sufficient explanation).
Do you see the point? Fine-tuning is necessary for us to be here but that fact doesn’t explain why the Universe is fine-tuned given the altogether more likely option given the odds- that it wouldn’t be.
Brian- Fine. But have you considered the multi-verse theory as a possible explanation of our finely tuned universe. Doesn’t a multi-verse rescue the chance option?
The Multi-verse theory contends that our universe is one of a possible infinite number of universes. Given an infinite amount of universes a life-permitting one is sure to arrive in the midst of all the cosmic clutter sooner or later. There is literally all the time in the universe for this ‘rare’ event to materialize.
The multi-verse makes the apparent improbability of a fine tuned universe not only probable but also necessary. According to some theorists one of the implications of the multi-verse theory is that any logically conceivable universe has been actualized at some point in cosmic history .
Imagine a wave with frothing bubbles riding its crest as it begins to break forcibly upon the uninterested, indifferent beach. Now, picture the cosmic landscape (engrossing and energizing all that is) as the wave. The bursting bubbles represent the continual emergence of new universes budging their way onto the cold, uncaring cosmic scene. Our universe just represents a single, local pocket of space in a far greater, mind expanding, and category imploding reality .
Some theorists have postulated that new universes are birthed when Black Holes collapse. It’s happening all the time in a universal evolutionary scheme .
Chris- That is fascinating. I like to think there could be a multitude of universes. It certainly would not diminish or detract from my faith in the creator God. But what is the scientific evidence for your Multi-verse theory?
Brian- Well, there is no empirical, or observational, evidence for a Multi-verse. In fact, I’m not entirely sure how there ever could be using sciences legitimate tools of investigation.
Chris- That’s what I thought. Your multi-verse theory, while interesting, requires a metaphysical leap to rescue chance as a possible explanation for our life-permitting cosmos.
Also, doesn’t the multi-verse theory lead to absurdities like, ‘there is a universe where I become president, a universe where I die in infancy, and a universe were the Holocaust is considered the greatest possible good’? All of these universes are logically conceivable so given the multi-verse theory wouldn’t they have to be actual at some point in cosmic history?
Brian- I’m not sure.
Chris- Either way we are left with a couple options: The universe is fine-tuned because a superior intellect meddled with physics, or there is an infinite number of unobservable universes and we just happen to be in the life-permitting one (of course).
Also, I often wonder why proponents of the multi-verse are comfortable with any eternal, necessary, casual entity provided we don’t call it God? I mean, doesn’t the multi-verse have some of the traditional attributes ascribed to God?
Brian- Interesting question.
Chris- Both positions take some faith to believe. Science can’t settle the issue empirically but perhaps Occam’s razor can help. You’ve heard of Occam’s razor, haven’t you?
Brian- Yes. Don’t unnecessarily multiple your hypothesis. Or in layman’s terms, ‘keep it simple stupid’.
Chris- Right. So which is the simpler explanation, ‘the universe looks designed because there is a designer’, or ‘there are a infinite number of universes, undetectable by us, that account for the arrival of our life friendly world’.
Perhaps, an analogy will help. Imagine you sit down with your friends to play a friendly game of poker. For the sake of Vegas realism the dealer of the game is impartial and not playing. You’ve never met the dealer before but you know he is a friend of one of the other card players.
As the game progresses one of your friends is dealt a Royal Flush 3 hands in a row. The third time he lays down his Royal Flush you get up from the table in a huff. You accuse your friend of cheating; the same friend who brought the ‘impartial’ dealer to the game.
Both the dealer and your friend protest, ‘I know the odds are stacked against us but what if there is an infinite number of universes and we just happen to be in the universe where I am dealt three Royal Flushes in a row by chance’ .
How would you respond? You would probably punch your friend in the face. Why? Simply because intelligent design is a far more reasonable explanation for your friends astounding ‘luck’ than a multi-verse.
My argument for a designer is based on what we do know. Design comes from designers. Fine-tuning proceeds from fine-tuners. You’re argument for a multi-verse is based on what we don’t know. Knowledge or ignorance? God or gaps? That is the choice. It’s not difficult for me to decide which is the simpler explanation.
Brian- But hasn’t Darwinian evolution taught us to be extremely skeptical about inferring a designer from the appearance of design in nature?
Chris- If you accept the Neo-Darwinian account of Evolution hook, line and sinker than yes. But Darwinism is a biological theory and it has no bearing on the laws of physics that apply to the fine-tuning of the universe. Evolution presupposes the fine-tuning of our universe for sentient, carbon-based creatures like ourselves- it can’t be used to explain the fine-tuning.
Brian- Fair enough. Look Chris, you raise some interesting points. Both you and I know, however, that you’re not a Cosmologist. You’re not an Astrophysicist. You’re speaking way out of your field.
Why should I take seriously what you say about Cosmology?
Chris- Why not?
Brian- Isn’t it obvious? You’re not educated in that field. You barely took any science in high school! Yet, you presume to lecture me about modern Cosmology.
Aren’t you being intellectually promiscuous? You’re sleeping with the sciences but you’ve stubbornly refused to marry any of them. You call them up when you need them but you refuse to fully embrace some of their unbecoming features that threaten your case contending for the credibility of Christianity.
For example, you know I love Albert Einstein. Here is what he wrote about your religion,
“The word god is for me nothing more than the expression and product of human weaknesses, the Bible a collection of honorable, but still primitive legends which are nevertheless pretty childish. No interpretation no matter how subtle can (for me) change this.”
Einstein’s comments on psychology and the origin of religion have rhetorical force and flourish but reflect a woeful ignorance. I’m honest enough to admit that. He is speaking outside of his field of academic pursuit. Just because Einstein is an authority in the realm of Relativity does not make him an expert in other areas of academic study. It’s like reading Freud on Philosophy.
His first sentence provides a textbook case of the genetic fallacy. I’m not sure that his comment accurately reflects how religion originated but even if it is ‘the product of human weakness’ showing how a belief originated is not the same as refuting that belief. .
How does a brilliant man like Albert Einstein commit a logical crime that a second year philosophy student could have side stepped? Simple. He was speaking outside of his field.
You are doing the same.
Chris- You’re right. I’m not a Cosmologist. I’m also not a fan of promiscuity but I find it ironic (in the improper but often used sense of the word) that you mention logical fallacies.
Brian- Why?
Chris- I think you’re committing one of your own. Your current complaint about my Fine-Tuning argument seems to be guilty of Argumentum Ad Hominem. It seems as though you try to discredit my above argument by impugning my supposed lack of scientific education.
An Ad Hominem attack is a logical fallacy because my character, or education, doesn’t have the deciding factor regarding the truth of the statements I’ve made (though it should rightly give you pause). But it can be a diversion tactic that allows you to dismiss me without actually dealing sufficiently with the arguments I put forward.
Everything I’ve said about fine-tuning, or cosmological constants comes directly from the writings of prominent, well respected Cosmologists and Astrophysicists, most of whom are not Christians. I’m not speaking based on my own credentials but theirs.
It’s getting late so let me end by summarizing the key premises in the above argument:
(1) The Universe is fine-tuned for life.
(2) The Fine-tuning isn’t plausibly due to chance or physical necessity. The odds are too overwhelming to be reasonably faced and the universe could have easily been different than it is.
(3) In our uniform experience when we see fine-tuning we assume there is a fine-tuner.
(4) The most plausible explanation of the Universes’ fine-tuning is that it was fine-tuned by an intelligent mind. This is in part what ‘theists’ mean by the word ‘God’.
Brian- If find this argument to be more compelling that the Cosmological argument you outlined in our previous discussion. I’ll have to think more about this.
Chris- Last time we talked I quoted Blaise Pascal. He once wrote that God gives ‘enough evidence to convince those whose hearts are open but not enough to convince those who hearts are closed’.
I believe there is enough evidence to justify believing in God. In fact, I think I’ve adequately displayed to you that Christianity is more reasonable than atheism given our experience of the world. There are many more arguments I could bring to bear, including the reality of God’s presence in my life and in the lives of believers that you dismissed at the beginning of our conversation.
I realize we can’t see God but there are many scientific entities that you firmly believe in which are in principle unobservable. We can’t see black holes or quarks but we infer their existence based on their observable influence on other entities that are within the realm of our sense experience.
It is the same with God. All of the above arguments are inferences to the best explanation based on what we do see and know. In the end faith, like marriage, is taking a leap but it is a leap based on knowledge and reason.
Are you ready to jump?
Brandon- Not yet.
