Answering some silly objections to the fine-tuning argument

Review: In case you need a refresher on the cosmological and fine-tuning arguments, as presented by a professor of particle physics at Stanford University, then click this link and watch the lecture.

If you already know about the standard arguments for theism from cosmology, then take a look at this post on Uncommon Descent.

Summary:

In my previous post, I highlighted three common atheistic objections to to the cosmological fine-tuning argument. In that post, I made no attempt to answer these objections. My aim was simply to show that the objections were weak and inconclusive.

Let’s go back to the original three objections:

1. If the universe was designed to support life, then why does it have to be so BIG, and why is it nearly everywhere hostile to life? Why are there so many stars, and why are so few orbited by life-bearing planets? (Let’s call this the size problem.)

2. If the universe was designed to support life, then why does it have to be so OLD, and why was it devoid of life throughout most of its history? For instance, why did life on Earth only appear after 70% of the cosmos’s 13.7-billion-year history had already elapsed? And Why did human beings (genus Homo) only appear after 99.98% of the cosmos’s 13.7-billion-year history had already elapsed? (Let’s call this the age problem.)

3. If the universe was designed to support life, then why does Nature have to be so CRUEL? Why did so many animals have to die – and why did so many species of animals have to go extinct (99% is the commonly quoted figure), in order to generate the world as we see it today? What a waste! And what about predation, parasitism, and animals that engage in practices such as serial murder and infant cannibalism? (Let’s call this the death and suffering problem.)

In today’s post, I’m going to try to provide some positive answers to the first two questions: the size problem and the age problem.

Here’s an excerpt for the size argument:

(a) The main reason why the universe is as big as it currently is that in the first place, the universe had to contain sufficient matter to form galaxies and stars, without which life would not have appeared; and in the second place, the density of matter in the cosmos is incredibly fine-tuned, due to the fine-tuning of gravity. To appreciate this point, let’s go back to the earliest time in the history of the cosmos that we can meaningfully talk about: the Planck time, when the universe was 10^-43 seconds old. If the density of matter at the Planck time had differed from the critical density by as little as one part in 10^60, the universe would have either exploded so rapidly that galaxies wouldn’t have formed, or collapsed so quickly that life would never have appeared. In practical terms: if our universe, which contains 10^80 protons and neutrons, had even one more grain of sand in it – or one grain less – we wouldn’t be here.

If you mess with the size of the universe, you screw up the mass density fine-tuning. We need that to have a universe that expands at the right speed in order to form galaxies, stars and planets. You need planets to have a place to form life – a place with liquid water at the surface.

And an excerpt for the age argument:

(a) One reason why we need an old universe is that billions of years were required for Population I stars (such as our sun) to evolve. These stars are more likely to harbor planets such as our Earth, because they contain lots of “metals” (astronomer-speak for elements heavier than helium), produced by the supernovae of the previous generation of Population II stars. According to currently accepted models of Big Bang nucleosynthesis, this whole process was absolutely vital, because the Big Bang doesn’t make enough “metals”, including those necessary for life: carbon, nitrogen, oxygen, phosphorus and so on.

Basically, you need heavy elements to make stars that burn slow and steady, as well as to make PEOPLE! And heavy elements have to be built up slowly through several iterations of the stellar lifecycle, including the right kinds of stellar death: supernovae.

Read the rest! These arguments come up all the time in debates with village atheists like Christopher Hitchens and Richard Dawkins. It’s a smokescreen they put up, but you’ve got to be able to answer it using the scientific evidence we have today.

By the way, the first post in that series got over 1200 views and over 100 comments. It’s worth reading as well.

UPDATE: Lenny from Come Reason has an article answering similar questions here.

Why should Christians study church history?

Mary send me this article from Probe. (H/T Mary via The Poached Egg)

Excerpt:

When I was in college, we had to do what was called “evangelism night.” It was a night in which a group of us would pile into someone’s old, broken-down car (we were all poor back then) and skirt downtown to the city’s walking bridge, a large half-mile overpass extending over the Chattanooga River. We were always sure that plenty of people would be there that needed our message. One night I began talking to a man about Christ and he quickly cut me off, “I am a Christian,” he exclaimed. “Great,” I replied. As we continue talking, though, I soon discovered that he was a “different” Christian than me. He said he believed in an expansive New Testament that contained many more books than the twenty-seven I was accustomed to, and he had six or seven Gospels, where I only had four. When I told him that I didn’t think he was right, that the New Testament only contained twenty-seven books and four Gospels, he asked me an important question, “How do you know that there are only four Gospels? Maybe there are more books to the Bible than you think!” I stood there, knowing that he was wrong. But I didn’t know why he was wrong. I had no idea of how to combat him—I didn’t know church history well enough in order to provide, as 1 Peter 3:15 says, an account of the assurance that lies within me.

This is one of the great reasons why we as Christians need to study church history. In this article I am going to make a passionate plea for the study of church history and give five reasons why I believe it is essential for every follower of Christ.

And here’s one of the five reasons:

The second reason is that Christians, just like any other people, go through many times of loneliness and despair. The book of Psalms reveals multiple times where various psalmists reveal that they feel as though God has left them, that their enemies are closing in, and that no one, including God, really cares. Suffice it to say that this often leads to a crisis of faith. Many of us suffer that same crisis from time to time, and the one thing that usually helps to be encouraged is to get around God’s people. When we are with others who believe as we do, it helps to stabilize, and to build, our faith. There is a sense in those moments of being with other Christians that our faith is bigger and more expansive—that it is communal, not merely individual.

Studying church history is about being with the community of faith. Reading the stories, learning the truths, examining the insights of these faithful men and women down through the centuries gives to us the sense that our faith is not shallow, but as the song used to say, it is “deep and wide.” Church historian John Hannah claims that studying Christian heritage “dispels the sense of loneliness and isolation in an era that stresses the peripheral and sensational.”{2} It breaks us away from this modern culture that emphasizes the glitz and the glamour of the here and now, and helps us to establish confidence in the faith by examining the beliefs central to our faith that have been developed over a long period of time. Christian theology does not invent beliefs; it finds beliefs already among Christians and critically examines them. The excavation site for Christian theology is not merely in the pages of Scripture, though that is the starting point, but it expands from there into the many centuries as we find the Holy Spirit leading His church. For us today, it gives us the ability to live each day absolutely sure that what we are believing in actually is true; to know and understand that for over 2000 years men and women have been worshipping, praising, and glorifying the same God that we do today.

It’s similar to those grand, majestic churches, the cathedrals that overwhelm you with the sense of transcendence. The expansive ceilings, high walls, and stained glass leaves the impression that our faith, our Christian heritage, is not small but large. Entering into a contemplation of our faith’s history is like going into one of those churches. It takes away the loneliness, the isolation, and reminds us of the greatness of our faith.

I probably spend too much time focused on science apologetics, so it’s nice to read something different.

William Lane Craig’s favorite philosopher, debate and books

From his Reasonable Faith podcast. (H/T Chris)

This man is by far the greatest defender of Christianity operating today… maybe the best (mortal) ever. If you can think of an atheist, he has probably debated him. The debate he calls his “favorite” carried me through my undergraduate degree – I printed out the transcript and kept it in my binder. I was a big fan of Leadership University then, so I had all of their Craig debates, plus I was ordering tapes from Integrated Resources.

The book he names “An Introduction to Christian Apologetics” by E.J. Carnell, was also my first book on apologetics, given to me by a Young Life youth pastor. I had the purple 1948 edition. Mine got to be in such a bad state of disrepair that I had to photocopy the entire book in order to save the binding, which was falling apart.
