Four times in the past year I have heard the following kind of statement from atheists: “Religious people are dangerous because they think they have answers to ultimate questions.” Twice these comments were uttered by personal friends of mine, and twice I heard them expressed by atheists in debates that I listened to via mp3. The first few times I heard the comment I didn’t think much of it. The fourth time, however, has bothered me enough that I need to respond.
What are the ultimate questions that religious people think they know the answers to? Generally, these are questions like the following:
Where did the universe come from?
How do we know what is right and what is wrong?
Does God exist?
What happens to us after we die?
What is the purpose of our lives?
Atheists seem to be alarmed by the fact that religious people think they have answers to these questions. The argument is that people who think they have answers to these questions are often dogmatic, uninterested in reason, irrational, arrogant, and exclusionary. The flip side of this argument is that people who claim to have no answers to these questions are open-minded, reasonable, rational, intellectually humble, and [inclusive].
They go on to answer the objection in the quote. But I’m not showing that here, you have to click through!
You may also be interested in this one question that you should ask all your atheist friends about their “moral” views. Ask them the question, then have a discussion with them about what morality really is, and what worldview grounds what morality really is.
Here’s a bio from his faculty page at Baylor University:
Walter Bradley (B.S., Ph.D. University of Texas at Austin) is Distinguished Professor of Engineering at Baylor. He comes to Baylor from Texas A&M University where he helped develop a nationally recognized program in polymeric composite materials. At Texas A&M, he served as director of the Polymer Technology Center for 10 years and as Department Head of Mechanical Engineering, a department of 67 professors that was ranked as high as 12th nationally during his tenure. Bradley has authored over 150 refereed research publications including book chapters, articles in archival journals such as the Journal of Material Science, Journal of Reinforced Plastics and Composites, Mechanics of Time-Dependent Materials, Journal of Composites Technology and Research, Composite Science and Technology, Journal of Metals, Polymer Engineering and Science, and Journal of Materials Science, and refereed conference proceedings.
Dr. Bradley has secured over $5.0 million in research funding from NSF grants (15 yrs.), AFOSR (10 years), NASA grants (10 years), and DOE (3 years). He has also received research grants or contracts from many Fortune 500 companies, including Alcoa, Dow Chemical, DuPont, 3M, Shell, Exxon, Boeing, and Phillips.
He co-authored The Mystery of Life Origin: Reassessing Current Theories and has written 10 book chapters dealing with various faith science issues, a topic on which he speaks widely.
He has received 5 research awards at Texas A&M University and 1 national research award. He has also received two teaching awards. He is an Elected Fellow of the American Society for Materials and the American Scientific Affiliation (ASA), the largest organization of Christians in Science and Technology in the world. He is President elect of the ASA and will serve his term in 2008.
Below, I analyze a lecture I chose from the hundreds of public lectures he has given all over the world on the integration of Christian faith with other public, testable areas of knowledge. In this lecture, entitled “Is There Scientific Evidence for an Intelligent Designer?“, Dr. Bradley explains how the progress of science has made the idea of a Creator and Designer of the universe more acceptable than ever before. (It’s a little different from the one I posted earlier in the week, and now I have summarized it so people can discuss it without having to watch the lecture).
1. The correspondence of natural phenomena to mathematical law
All observations of physical phenomena in the universe, such as throwing a ball up in the air, are described by a few simple, elegant mathematical equations.
2. The fine-tuning of physical constants and rations between constants in order to provide a life-permitting universe
Life has certain minimal requirements; long-term stable source of energy, a large number of different chemical elements, an element that can serve as a hub for joining together other elements into compounds, etc.
In order to meet these minimal requirements, the physical constants, (such as the gravitational constant), and the ratios between physical constants, need to be withing a narrow range of values in order to support the minimal requirements for life of any kind.
Slight changes to any of the physical constants, or to the rations between the constants, will result in a universe inhospitable to life.
The range of possible ranges over 70 orders of magnitude.
Although each individual selection of constants and ratios is as unlikely as any other selection, the vast majority of these possibilities do not support the minimal requirements of life of any kind. (In the same way as any hand of 5 cards that is dealt is as likely as any other, but you are overwhelmingly likely NOT to get a royal flush. In our case, a royal flush is a life-permitting universe).
Examples of finely-tuned constants and ratios: (there are more examples in the lecture)
a) The strong force: (the force that binds nucleons (= protons and neutrons) together in nucleus, by means of meson exchange)
if the strong force constant were 2% stronger, there would be no stable hydrogen, no long-lived stars, no hydrogen containing compounds. This is because the single proton in hydrogen would want to stick to something else so badly that there would be no hydrogen left!
if the strong force constant were 5% weaker, there would be no stable stars, few (if any) elements besides hydrogen. This is because you would be able to build up the nuclei of the heavier elements, which contain more than 1 proton.
So, whether you adjust the strong force up or down, you lose stars than can serve as long-term sources of stable energy, or you lose chemical diversity, which is necessary to make beings that can perform the minimal requirements of living beings. (see below)
b) The conversion of beryllium to carbon, and carbon to oxygen
Life requires carbon in order to serve as the hub for complex molecules, but it also requires oxygen in order to create water.
Carbon is like the hub wheel in a tinker toy set: you can bind other elements together to more complicated molecules (e.g. – “carbon-based life), but the bonds are not so tight that they can’t be broken down again later to make something else.
The carbon resonance level is determined by two constants: the strong force and electromagnetic force.
If you mess with these forces even slightly, you either lose the carbon or the oxygen.
3. Fine-tuning to allow a habitable planet
A number of factors must be fine-tuned in order to have a planet that supports life
Initial estimates predicted abundant life in the universe, but revised estimates now predict that life is almost certainly unique in the galaxy, and probably unique in the universe.
Even though there are lots of stars in the universe, the odds are against any of them supporting complex life.
Here are just a few of the minimal requirements for habitability: must be a single star solar system, in order to support stable planetary orbits, the planet must be the right distance from the sun in order to have liquid water at the surface, the planet must sufficient mass in order to retain an atmosphere, etc.
The best current atheist response to this is to speculate that there may be an infinite number of unobservable and untestable universes. (I.e. – the Flying Spaghetti Monster did it)
1. The progress of science has shown that the entire physical universe came into being out of nothing (= “the big bang”). It also shows that the cause of this creation event is non-physical and non-temporal. The cause is supernatural.
Atheism prefers an eternal universe, to get around the problem of a Creator having to create the universe.
Discovery #1: Observations of galaxies moving away from one another confirms that the universe expanded from a single point.
Discovery #2: Measurements of the cosmic background radiation confirms that the universe exploding into being.
Discovery #3: Predictions of elemental abundances prove that the universe is not eternal.
Discovery #4:The atheism-friendly steady-state model and oscillating model were both falsified by the evidence.
And there were other discoveries as well, mentioned in the lecture.
The best atheistic response to this is to speculate that there is an unobservable and untestable hyper-universe outside our own. (I.e. – the Flying Spaghetti Monster did it)
1. The progress of science has shown that the simplest living organism contains huge amounts of biological information, similar to the Java code I write all day at work. This is a problem for atheists, because the sequence of instructions in a living system has to come together all at once, it cannot have evolved by mutation and selection – because there was no replication in place prior to the formation of that first living system!
Living systems must support certain minimum life functions: processing energy, storing information, and replicating.
There needs to be a certain amount of complexity in the living system that can perform these minimum functions.
But on atheism, the living system needs to be simple enough to form by accident in a pre-biotic soup, and in a reasonable amount of time.
The minimal functionality in a living system is a achieved by DNA, RNA and enzymes. DNA and RNA are composed of sequences of proteins, which are in turn composed of sequences of amino acids.
Consider the problems of building a chain of 100 amino acids
The amino acids must be left-handed only, but left and right kinds are equally abundant in nature. How do you sort out the right-handed ones?
The amino acids must be bound together using peptide bonds. How do you prevent other types of bonds?
Each link of the amino acid chain needs to be carefully chosen such that the completed chain with fold up into a protein. How do you choose the correct amino acid for each link from the pool of 20 different kinds found in living systems?
In every case, a human or other intelligence could solve these problems by doing what intelligent agents do best: making choices.
But who is there to make the choices on atheism?
The best current atheistic response to this is to speculate that unobservable and untestable aliens seeded the earth with life. (I.e. – the Flying Spaghetti Monster did it)
The problem of the origin of life is not a problem of chemistry, it is a problem of engineering. Every part of car functionality can be understood and described using the laws of physics and chemistry. But an intelligence is still needed in order to assemble the components into a system that has the minimal requirements for a functioning vehicle.
Conclusion
In all three areas, scientists expected that the data would be consistent with atheism. First, scientists expected that life could exist even if the physical constants and ratios were altered. The progress of science said NO. Second, scientists expected that the universe would be eternal. The progress of science said NO. Third, scientists expected that the origin of life would be simple. The progress of science said NO. Why do some people resist the progress of science and cling to the religious dogma of materialism?
Science Daily reports on a new factor that affects planetary habitability: tides. Specifically, tides can affect the surface temperature of a planet, which has to be within a certain range in order to support liquid water – a requirement for life of any conceivable kind.
Excerpt:
Tides can render the so-called “habitable zone” around low-mass stars uninhabitable. This is the main result of a recently published study by a team of astronomers led by René Heller of the Astrophysical Institute Potsdam.
[…]Until now, the two main drivers thought to determine a planet’s temperature were the distance to the central star and the composition of the planet’s atmosphere. By studying the tides caused by low-mass stars on their potential earth-like companions, Heller and his colleagues have concluded that tidal effects modify the traditional concept of the habitable zone.
Heller deduced this from three different effects. Firstly, tides can cause the axis of a planet`s rotation to become perpendicular to its orbit in just a few million years. In comparison, Earth’s axis of rotation is inclined by 23.5 degrees — an effect which causes our seasons. Owing to this effect, there would be no seasonal variation on such Earth-like planets in the habitable zone of low-mass stars. These planets would have huge temperature differences between their poles, which would be in perpetual deep freeze, and their hot equators which in the long run would evaporate any atmosphere. This temperature difference would cause extreme winds and storms.
The second effect of these tides would be to heat up the exoplanet, similar to the tidal heating of Io, a moon of Jupiter that shows global vulcanism.
Finally, tides can cause the rotational period of the planet (the planet’s “day”) to synchronize with the orbital period (the planet’s “year”). This situation is identical to the Earth-moon setup: the moon only shows Earth one face, the other side being known as “the dark side of the moon.” As a result one half of the exoplanet receives extreme radiation from the star while the other half freezes in eternal darkness.
The habitable zone around low-mass stars is therefore not very comfortable — it may even be uninhabitable.
Here is my previous post on the factors needed for a habitable planet. Now we just have one more. I actually find this article sort of odd, because my understanding of stars was that only high-mass stars could support life at all. This is because if the mass of the planet was too low, the habitable zone wouldbe very close to the star. Being too close to the star causes tidal locking, which means that the planet doesn’t spin on its axis at all, and the same side faces the star. This is a life killer.
This astrophysicist who teaches at the University of Wisconsin explains it better than me.
Excerpt:
Higher-mass stars tend to be larger and luminous than their lower-mass counterparts. Therefore, their habitable zones are situated further out. In addition, however, their HZs are much broader. As an illustration,
a 0.2 solar-mass star’s HZ extends from 0.1 to 0.2 AU
a 1.0 solar-mass star’s HZ extends from 1 to 2 AU
a 40 solar-mass star’s HZ extends from 350 to 600 AU
On these grounds, it would seem that high-mass starts are the best candidates for finding planets within a habitable zone. However, these stars emit most of their radiation in the far ultraviolet (FUV), which can be highly damaging to life, and also contributes to photodissociation and the loss of water. Furthermore, the lifetimes of these stars is so short (around 10 million years) that there is not enough time for life to begin.
Very low mass stars have the longest lifetimes of all, but their HZs are very close in and very narrow. Therefore, the chances of a planet being formed within the HZ are small. Additionally, even if a planet did form within the HZ, it would become tidally locked, so that the same hemisphere always faced the star. Even though liquid water might exist on such a planet, the climactic conditions would probably be too severe to permit life.
In between the high- and low-mass stars lie those like our own Sun, which make up about 15% percent of the stars in the galaxy. These have reasonably-broad HZs, do not suffer from FUV irradiation, and have lifetimes of the order of 10 billion years. Therefore, they are the best candidates for harbouring planets where life might be able to begin.
This guy is just someone I found through a web search. He has a support-the-unions-sticker on his web page, so he’s a liberal crackpot. But he makes my point, anyway, so that’s good enough for me.
Maybe the new discovery is talking about this, but I already knew about it because I watched The Privileged Planet DVD. Actually that whole video is online, and the clip that talks about the habitable zone and water is linked in this blog post I wrote before.
