Why is the universe so big, and why is so much of it hostile to life?

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. They always want to dismiss God with their personal preferences about what God should or should not do. But the real issue is the design of the cosmological constants that allow life to anywhere. That’s the part that’s designed. And that’s not a matter of personal preference, it’s a matter of mathematics and experimental science.

One last parting shot. If God made the universe have life everywhere, the first thing atheists would say is “See? Life evolves fine by itself without any God!” The only way to recognize a marksman is when he hits a narrow target (not hostile to life) from a wide range of possibilities that have no value (hostile to life). We don’t credit Chris Kyle for hitting the wall above an Islamic terrorist from a mile away, we credit Chris Kyle for hitting an Islamic terrorist a mile away. The design is not how much of the universe is hospitable to life versus how much is hostile to life. The design is in the cosmological constants – where we are in the narrow band that is hospitable to life and not in the huge regions that are hostile to life.

You can read the best explanation of the design argument in this lecture featuring Robin Collins. That link goes to my post which has a summary of the lecture. He has a new lecture that I also blogged about where he extends the fine-tuning argument down to the level of particle physics. I have a summary of that one as well.

What criteria do historians use to get to the minimal facts about the historical Jesus?

Have you ever heard Gary Habermas, Michael Licona or William Lane Craig defend the resurrection of Jesus in a debate by saying that the resurrection is the best explanation for the “minimal facts” about Jesus? The lists of minimal facts that they use are typically agreed to by their opponents during the debates. Minimal facts are the parts of the New Testament that meet a set of strict historical criteria. These are the facts that skeptical historians agree with, totally apart from any religious beliefs.

So what are the criteria that skeptical historians use to derive a list of minimal facts about Jesus?

Dr. Craig explains them in this article.

Excerpt:

The other way, more influential in contemporary New Testament scholarship, is to establish specific facts about Jesus without assuming the general reliability of the Gospels. The key here are the so-called “Criteria of Authenticity” which enable us to establish specific sayings or events in Jesus’ life as historical. Scholars involved in the quest of the historical Jesus have enunciated a number of these critieria for detecting historically authentic features of Jesus, such as dissimilarity to Christian teaching, multiple attestation, linguistic semitisms, traces of Palestinian milieu, retention of embarrassing material, coherence with other authentic material, and so forth.

It is somewhat misleading to call these “criteria,” for they aim at stating sufficient, not necessary, conditions of historicity. This is easy to see: suppose a saying is multiply attested and dissimilar but not embarrassing. If embarrassment were a necessary condition of authenticity, then the saying would have to be deemed inauthentic, which is wrong-headed, since its multiple attestation and dissimilarity are sufficient for authenticity. Of course, the criteria are defeasible, meaning that they are not infallible guides to authenticity. They might be better called “Indications of Authenticity” or “Signs of Credibility.”

In point of fact, what the criteria really amount to are statements about the effect of certain types of evidence upon the probability of various sayings or events in Jesus’ life. For some saying or event S and evidence of a certain type E, the criteria would state that, all things being equal, the probability of S given E is greater than the probability of S on our background knowledge alone. So, for example, all else being equal, the probability of some event or saying is greater given its multiple attestation than it would have been without it.

What are some of the factors that might serve the role of E in increasing the probability of some saying or event S? The following are some of the most important:

(1) Historical congruence: S fits in with known historical facts concerning the context in which S is said to have occurred.

(2) Independent, early attestation: S appears in multiple sources which are near to the time at which S is alleged to have occurred and which depend neither upon each other nor a common source.

(3) Embarrassment: S is awkward or counter-productive for the persons who serve as the source of information for S.

(4) Dissimilarity: S is unlike antecedent Jewish thought-forms and/or unlike subsequent Christian thought-forms.

(5) Semitisms: traces in the narrative of Aramaic or Hebrew linguistic forms.

(6) Coherence: S is consistent with already established facts about Jesus.

For a good discussion of these factors see Robert Stein, “The ‘Criteria’ for Authenticity,” in Gospel Perspectives I, ed. R. T. France and David Wenham (Sheffield, England: JSOT Press, 1980), pp. 225-63.

Notice that these “criteria” do not presuppose the general reliability of the Gospels. Rather they focus on a particular saying or event and give evidence for thinking that specific element of Jesus’ life to be historical, regardless of the general reliability of the document in which the particular saying or event is reported. These same “criteria” are thus applicable to reports of Jesus found in the apocryphal Gospels, or rabbinical writings, or even the Qur’an. Of course, if the Gospels can be shown to be generally reliable documents, so much the better! But the “criteria” do not depend on any such presupposition. They serve to help spot historical kernels even in the midst of historical chaff. Thus we need not concern ourselves with defending the Gospels’ every claim attributed to Jesus in the gospels; the question will be whether we can establish enough about Jesus to make faith in him reasonable.

And you can see Dr. Craig using these criteria to defend minimal facts in his debates. For example, in his debate with Ehrman, he alludes to the criteria when making his case for the empty tomb.

Here, he uses multiple attestation and the criteria of embarrassment:

Among the reasons which have led most scholars to this conclusion are the following:

1. The empty tomb is also multiply attested by independent, early sources.

Mark’s source didn’t end with the burial, but with the story of the empty tomb, which is tied to the burial story verbally and grammatically. Moreover, Matthew and John have independent sources about the empty tomb; it’s also mentioned in the sermons in the Acts of the Apostles (2.29; 13.36); and it’s implied by Paul in his first letter to the Corinthian church (I Cor. 15.4). Thus, we have again multiple, early, independent attestation of the fact of the empty tomb.

2. The tomb was discovered empty by women.

In patriarchal Jewish society the testimony of women was not highly regarded. In fact, the Jewish historian Josephus says that women weren’t even permitted to serve as witnesses in a Jewish court of law. Now in light of this fact, how remarkable it is that it is women who are the discoverers of Jesus’ empty tomb. Any later legendary account would certainly have made male disciples like Peter and John discover the empty tomb. The fact that it is women, rather than men, who are the discoverers of the empty tomb is best explained by the fact that they were the chief witnesses to the fact of the empty tomb, and the Gospel writers faithfully record what, for them, was an awkward and embarrassing fact.

There are actually a few more reasons for believing in the empty tomb that he doesn’t go into in the debate, but you can find them in his written work. For example, in his essay on Gerd Ludemann’s “vision” hypothesis. That essay covers the reasons for all four of his minimal facts.

So, if you are going to talk about the resurrection with a skeptic, you don’t want to invoke the Bible as some sort of inerrant/inspired Holy Book.

Try this approach instead:

  1. Explain the criteria that historians use to get their lists of minimal facts
  2. Explain your list of minimal facts
  3. Defend your list of minimal facts using the criteria
  4. Cite skeptics who admit to each of your minimal facts, to show that they are widely accepted
  5. List some parts of the Bible that don’t pass the criteria (e.g. – guard at the tomb, Matthew earthquake)
  6. Explain why those parts don’t pass the criteria, and explain that they are not part of your case
  7. Challenge your opponent to either deny some or all the facts, or propose a naturalistic alternative that explains the facts better than the resurrection
  8. Don’t let your opponent attack any of your minimal facts by attacking other parts of the Bible (e.g. – the number of angels being one or two, etc.)

And remember that there is no good case for the resurrection that does not make heavy use of the early creed in 1 Corinthians 15:3-8. You have to use that – it’s the law.

Back to the minimal facts criteria. The best essay on the minimal facts criteria that I’ve read is the one by Robert H. Stein in “Contending with Christianity’s Critics“. It’s a good short essay that goes over all the historical criteria that are used to derive the short list of facts from which we infer the conclusion “God raised Jesus from the dead”. That whole book is really very, very good.

Is there any downside to raising the minimum wage to $15 an hour?

They told me if I voted Republican, we'd lose jobs, and they were right!
They told me if I voted Republican, we’d lose jobs, and they were right!

This article is from the libertarian Reason.com. They’re terrible at social issues, but really really good at economics.

They write:

Raising the minimum wage like this is an idea that’s become increasingly common amongst more liberal Democratic politicians and policymakers: The city of Seattle, Washington passed a law raising its minimum wage to $15 last year, and the Los Angeles city council voted to follow suit. Soon after, New York state announced a plan to raise the minimum wage of all fast food workers to $15, and the state’s governor, Andrew Cuomo, recently said he believes it should apply to all workers.

Many of these plans start from the assumption, implicitly or explicitly, that these minimum wage hikes would be relatively cost-free, pointing to several studies seeming to show that increases in the minimum wage don’t have much effect on jobs.

Here is what the author of some of the most influential of those studies, former Obama administration economic adviser Alan B. Krueger, had to say about raising the federal minimum wage to $15 an hour in an op-ed for The New York Times last week:

15 an hour is beyond international experience, and could well be counterproductive. Although some high-wage cities and states could probably absorb a $15-an-hour minimum wage with little or no job loss, it is far from clear that the same could be said for every state, city and town in the United States.

Krueger goes on to warn of greater risk, and the potential for “severe” trade-offs, if policymakers pursue a $15 minimum wage, warning that it would go beyond what any research supports. Ultimately, he concludes, it is  “a risk not worth taking.”

Krueger wasn’t disowning his own work or abandoning his position. He still supports raising the minimum wage to $12 an hour over a period of years, which he thinks could be done with essentially no job loss.

There are some reasons to be skeptical of that claim too: The Congressional Budget Office, which generally tries to take a moderate approach to economic evidence and put its estimates right in the middle of the consensus range, found that even a more modest hike to $10.10 an hour nationally would most likely cost about a half a million jobs, and while it’s possible such a raise might produce minimal job loss, it’s equally possible that it would cost a million jobs.

Overall, as David Neumark and William Wascher have found, the bulk of the evidence from research into the minimum wage suggests that hikes tend to decrease employment.

Let’s review the facts on minimum wage.

Abstract from a National Bureau of Economic Research study:

We estimate the minimum wage’s effects on low-skilled workers’ employment and income trajectories. Our approach exploits two dimensions of the data we analyze. First, we compare workers in states that were bound by recent increases in the federal minimum wage to workers in states that were not. Second, we use 12 months of baseline data to divide low-skilled workers into a “target” group, whose baseline wage rates were directly affected, and a “within-state control” group with slightly higher baseline wage rates. Over three subsequent years, we find that binding minimum wage increases had significant, negative effects on the employment and income growth of targeted workers.

[…]Over the late 2000s, the average effective minimum wage rose by 30 percent across the United States. We estimate that these minimum wage increases reduced the national employment-to-population ratio by 0.7 percentage point.

That comes out to 1.4 million workers who lost their jobs, thanks to minimum wage mandates. And those are primarily young, unskilled workers who are affected – people trying to get a start in the workplace and build their resumes, so they can move up.

Harvard economist Greg Mankiw explains the top 14 views that a majority professional economists agree on, and here’s #12:

12. A minimum wage increases unemployment among young and unskilled workers. (79%)

This is not controversial. This is the kind of basic “how America works” economics stuff that people used to learn in their civics classes before the schools became so politicized.
