Dr. Walter Bradley lectures on scientific evidence the creation and design of the universe

8 Comments

This lecture is special to me, because I bought a VHS tape of it just after I started working full-time, and watched it a million times. A lot of people come to their convictions about God’s existence because of parents or church or intuitions, but for me it’s all about the scientific evidence. This lecture changed my life. I wish more people taught their children about this evidence! This lecture was delivered at the University of California, Santa Barbara.

About the speaker:

Dr. Bradley received his B.S. in Engineering Science and his Ph.D. in Materials Science from the University of Texas in Austin.

Dr. Bradley taught for eight years at the Colorado School of Mines before assuming a position as Professor of Mechanical Engineering at Texas A&M University (TAMU) in 1976.

During his 24 years at Texas A&M, Dr. Bradley served as Head of the Department of Mechanical Engineering at Texas A&M University and as Director of the Polymer Technology Center, and received five College of Engineering Research Awards. He has received over $4,500,000 in research grants and has published over 140 technical articles and book chapters. He has also co-authored “The Mystery Of Life’s Origin: Reassessing Current Theories. He is a Fellow of the American Society for Materials and of the American Scientific Affiliation and serves as a consultant for many Fortune 500 companies.

He currently serves as Distinguished Professor of Engineering at Baylor University.

Introduction:

  • At the beginning of the 20th century, people believed that the progress of science was pointing away from an intelligent Creator and Designer, and towards naturalism
  • A stream of new discoveries has shifted the support of science towards theism, and away from naturalism
  • Richard Dawkins, an atheist, says that nature only has the appearance of design, but that if you look closer, naturalistic mechanisms can account for the appearance of design
  • When deciding between design and apparent design (“designoid”), it matters whether you think there is an intelligence there to do the designing

Evidence #1: The Big Bang:

  • an eternal “steady state” universe is more compatible with naturalism, but a created universe is more compatible with a Creator
  • In 1929, Hubble used telescopes to observe that the light from distant galaxies was redshifted. The further away galaxies were, the faster they were moving away. Therefore, space is expanding in all directions, suggesting an explosive origin of the universe
  • In 1965, the discovery of the cosmic microwave background radiation matched a prediction of the Big Bang cosmology, and of the creation event
  • In 1992, the COBE space telescope allowed us to test four specific predictions of the Big Bang model, especially the predictions for light element abundances (hydrogen and helium), which matched the predictions of the creation model

Evidence #2: Simple mathematical structure of the physical laws

  • the simple mathematical structure of natural laws allows us to understand these laws, make discoveries, and engineer solutions to problems
  • early scientists saw the mathematical structure of the universe to mean that nature was designed by an intelligent to be understood
  • the fundamental equations of the laws of the universe can be easily written on one side of one sheet of paper
  • Eugene Wigner’s famous paper, “The Unreasonable Effectiveness of Mathematics in the Physical Sciences” makes the point that this simple structure is an unexpected gift that allows is to do science

Evidence #3: fine-tuning of the physical constants and quantities

  • in order for any kind of complex life to survive, we need stars that provide energy within specific ranges for long periods of time
  • in order for any kind of complex life to survive, we need planets with stable orbits that will not suffer from extreme temperature swings as it varies in distance from its star
  • in order for any kind of complex life to survive, we need stable atomic structure
  • in order for any kind of complex life to survive, we need to have chemical diversity and correct relative abundances of each element
  • organic life has minimum requirements: process energy, store information, replicate, and you can’t fulfill those functions if there is only one element, e.g. – hydrogen
  • the energy level from the photons from the sun have to match the energy levels of the different elements in order to drive the chemical bonding needed for life
  • These requirements for life of any imaginable type depend on the values of the constants and quantities. The constants and quantities cannot vary much from what they are, or the universe will lose the characteristics (above) that allow it to support complex life of any imaginable time
  • For example, ratio of strong force to electromagnetic force:
    – if 2% larger, then no stable hydrogen, no long-lived stars, no compounds containing hydrogen, e.g. – water
    – if 5% smaller, no stable stars, heavy hydrogen would be unstable, few elements other than hydrogen

Evidence #4: initial conditions for habitability

  • Universe: expansion rate of the universe must be fast enough to avoid a re-collapse, but slow enough to allow matter to clump together and form stars and planets for complex life to live on
  • Planet: right distance from the star to get the right climate
  • Planet: right mass to retain the right atmosphere

Evidence #5: origin of life and information theory

  • It’s possible to explain every process in an automobile engine using plain old naturalistic mechanisms – no supernatural explanation is necessary to understand the processes
  • But the existence of engine itself: engineering all the parts has to be explained by the work of an intelligence
  • Similarly, we can understand how living systems work, but the existence of the living systems requires an intelligence
  • Even the simplest living system has to perform minimal function: capture energy, store information and replicate
  • Living systems are composed of objects like proteins that are composed of sequences of components complex such that the order of the components gives the overall structure function
  • Developing the components for a simple living cell is very improbable – even given the large number of galaxies, stars and planets in the universe, it is unlikely that complex, embodied life would exist anywhere in the universe

Evidence #6: more initial conditions for habitability

  • Location within the galaxy: you need to be away from the center of the galaxy, because the explosions from dying stars, and excessive radiation will kill life
  • Location within the galaxy: you need to be close enough to the center in order catch the heavy elements you need for life from the explosions of other stars
  • Location within the galaxy: the best location is between two arms of  a spiral galaxy, where you can get the heavy elements you need from dying stars, but without being hit with explosions and harmful radiation
  • Star mass: determines rate at which the sun burns, determines the energy level of photons that are used to drive chemical bonding reactions, determines the length of time the star will be stable
  • Star mass: star mass must be the correct value in order to allow liquid water on the planet’s surface, while still preserving stable orbit

I wish there was more curiosity about science in churches, and young Christians understood how critical science is for grounding the rationality of the Christian worldview. We need to be training up more scientists who think about the big questions, like Dr. Walter Bradley.

Men on strike: the social changes that caused men to opt out of marriage

Painting: "Courtship", by Edmund Blair Leighton (1888)
Painting: “Courtship”, by Edmund Blair Leighton (1888)

I read and enjoyed Dr. Helen Smith’s book “Men on Strike” a few years back. The book explains a few of the developments that have led to men underperforming in school and in the workplace, and opting out of marriage and fatherhood.

Dr. Helen comes to this problem as a secular libertarian, not as a Christian conservative.

A review of Dr. Helen’s book appeared in Salvo magazine. The review is written by Terrell Clemmons, who has the best Christian worldview of any woman I know – I frequently rely on her advice.

Terrell writes:

While the feminist movement may originally have been about equal respect for both sexes, what it has morphed into, she argues, is female privilege. From rape laws that empower women but not the men they may falsely accuse, to divorce laws tilted in favor of the wife, to the feminization of the U.S. education system, men have become the sex under the gun, while women enjoy the status of a protected class.

But unlike their mothers or grandmothers, men today are not taking to the streets burning their undergarments and shrieking demands (thank God). They’re doing just the opposite, which is far worse. They’re going on strike. The strike zones are manifold:

Higher Education.In addition to the enrollment imbalance, which is approaching a 60/40 ratio of women to men, college has become, in the words of one professor, “a hostile working environment [in which] males increasingly feel emasculated.” Smith quotes a student named John, who had this to say about his college experience: “I had already been cautious around women, having grown up with Tawana Brawley in my backyard and daily stories of sexual harassment; I played it safe and passive every time. But it doesn’t matter. The only way not to lose is to not play. So I’m out.”

Work,including community involvement. With higher female graduation rates and salaries, men today are falling behind their fathers economically and professionally. Consequently, their efforts to prove themselves worthy mates through hard work and higher earnings don’t win female attention the way they used to. Discouraged, too many retreat to a man cave, and inertia sets in from there.

Marriage.Marriage rates are down, and honest men opting out will tell you why. Smith cites a Rutgers University study of single heterosexual men which turned up the top reasons they hadn’t married. They can get sex and the companionship of cohabitation without marriage more easily than in times past, and they don’t want to open themselves up to the risk of divorce and financial loss. It really isn’t that complicated a decision. In fact, it’s often not an actual decision at all. It just happens.

The simplest explanation for the difficulties that boys face in an education system that is dominated by women (teachers and administrators) is discrimination. And in the workplace, the government requires employers to report on male and female head counts, and promote women who are not qualified. I have seen receptionists with tattoos and no college degrees promoted to six-figure manager jobs in companies where I worked.

There is one more which to me was the most surprising one in the book – paternity fraud, and the laws that support paternity fraud:

Take the following cases of nonconsensual insemination: Nathaniel from California, age 15, had sex with 34-year-old Ricci, which, due to his age, was legally considered nonconsensual. Emile from Louisiana was visiting his parents in the hospital when a nurse offered him oral sex, if he wore a condom, which she conveniently offered to dispose of for him afterward. S. F. from Alabama passed out drunk at the home of a female friend and awoke undressed the following morning. In all three cases, including the one involving the minor, a woman got sperm and, nine months later, a child, and the man got ordered by a court of law to pay support for eighteen years.

Less devious, but similarly amiss, are those cases in which a man, having been betrayed by his wife or girlfriend, was nevertheless held financially responsible for a child genetically proven to be another man’s offspring. While not as sensational as sperm-jacking, it is another form of paternity extortion.

In each of those cases, the man was found liable to pay child support – including the case of the 15-year-old boy, who was forced to pay child support to his statutory rapist when he turned 18. This is how the court system works, and more and more men are understanding the risks.

I often encounter “pro-marriage” people while gathering stories for the blog. These pro-marriage people come in two varieties.

On the one end of the spectrum are people like Terrell Clemmons and Jennifer Roback Morse, who understand marriage, but who also understand the social changes that have made marriage unattractive for men. Both Clemmons and Morse have a background in STEM fields, so they are able to understand incentives and tradeoffs. They understand that society has to rollback the changes to education, divorce laws, etc. if they expect men to be interested in marriage again. They understand that men are not just accessories of women, but instead have their own desires, feelings and reasons for marrying.

On the other end of the spectrum are feminist men, who are not able to understand the changing incentives that face men in a world that has evolved under the influence of radical feminism. It is just simpler (less thinking) for these men to accept the radical feminism as a given, and then urge men to “man up”. I think a much better idea would be for the “man up” crowd to realize how marriage has changed, and how the schools and the workplace have changed, then make all of these things more attractive to men. It doesn’t do any good to try to “dare” men into jumping off a cliff. Men aren’t stupid, and they do what is in their own best interests. If the man-up crowd wants younger men to marry, then they need to change the incentives offered to men. And that means changing women first.

Stephen C. Meyer lectures on intelligent design and the origin of life

Christianity and the progress of science

A MUST-SEE lecture based on Dr. Stephen C. Meyer’s book “Signature in the Cell“.

I highly recommend watching the lecture, and looking at the slides. The quality of the video and the content is first class. There is some Q&A (9 minutes) at the end of the lecture.

Topics:

  • intelligent design is concerned with measuring the information-creating capabilities of natural forces like mutation and selection
  • Darwinists think that random mutations and natural selection can explain the origin and diversification of living systems
  • Darwinian mechanisms are capable of explaining small-scale adaptive changes within types of organisms
  • but there is skepticism, even among naturalists, that Darwinian mechanisms can explain the origin of animal designs
  • even if you concede that Darwinism can account for all of the basic animal body plans, there is still the problem of life’s origin
  • can Darwinian mechanisms explain the origin of the first life? Is there a good naturalistic hypothesis to explain it?
  • there are at least two places in the history of life where new information is needed: origin of life, and Cambrian explosion
  • overview of the structure of DNA and protein synthesis (he has helpful pictures and he uses the snap lock blocks, too)
  • the DNA molecule is composed of a sequence of bases that code for proteins, and the sequence is carefully selected to have biological function
  • meaningful sequences of things like computer code, English sentences, etc. require an adequate cause
  • it is very hard to arrive at a meaningful sequence of a non-trivial length by randomly picking symbols/letters
  • although any random sequence of letters is improbable, the vast majority of sequences are gibberish/non-compiling code
  • similarly, most random sequences of amino acids are lab-proven (Doug Axe’s work) to be non-functional gibberish
  • the research showing this was conducted at Cambridge University and published in the Journal of Molecular Biology
  • so, random mutation cannot explain the origin of the first living cell
  • however, even natural selection coupled with random mutation cannot explain the first living cell
  • there must already be replication in order for mutation and selection to work, so they can’t explain the first replicator
  • but the origin of life is the origin of the first replicator – there is no replication prior to the first replicator
  • the information in the first replicator cannot be explained by law, such as by chemical bonding affinities
  • the amino acids are attached like magnetic letters on a refrigerator
  • the magnetic force sticks the letters ON the fridge, but they don’t determine the specific sequence of the letters
  • if laws did determine the sequence of letters, then the sequences would be repetitive
  • the three materialist explanations – chance alone, chance and law, law alone – are not adequate to explain the effect
  • the best explanation is that an intelligent cause is responsible for the biological explanation in the first replicator
  • we know that intelligent causes can produce functional sequences of information, e.g. – English, Java code
  • the structure and design of DNA matches up nicely with the design patterns used by software engineers (like WK!)

There are some very good tips in this lecture so that you will be able to explain intelligent design to others in simple ways, using everyday household items and children’s toys to symbolize the amino acids, proteins, sugar phosphate backbones, etc.

Proteins are constructed from a sequence of amino acids:

A sequence of amino acids forming a protein
A sequence of amino acids forming a protein

Proteins sticking onto the double helix structure of DNA:

Some proteins sticking onto the sugar phosphate backbone
Some proteins sticking onto the sugar phosphate backbone

I highly, highly recommend this lecture. You will be delighted and you will learn something.

Here is an article that gives a general overview of how intelligent design challenges. If you want to read something more detailed about the material that he is covering in the lecture above related to the origin of life, there is a pretty good article here.

There is a good breakdown of some of the slides with helpful flow charts here on Uncommon Descent.
