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

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.

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.

Bible study: the importance of truth in religion

Bible study that hits the spot
Bible study that hits the spot

Here’s an interesting passage of the Bible. What do you all think the practical value of this passage is?

1 In the second year of his reign, Nebuchadnezzar had dreams; his mind was troubled and he could not sleep.

2 So the king summoned the magicians, enchanters, sorcerers and astrologers to tell him what he had dreamed. When they came in and stood before the king,

3 he said to them, “I have had a dream that troubles me and I want to know what it means.”

4 Then the astrologers answered the king, “May the king live forever! Tell your servants the dream, and we will interpret it.”

5 The king replied to the astrologers, “This is what I have firmly decided: If you do not tell me what my dream was and interpret it, I will have you cut into pieces and your houses turned into piles of rubble.

6 But if you tell me the dream and explain it, you will receive from me gifts and rewards and great honor. So tell me the dream and interpret it for me.”

7 Once more they replied, “Let the king tell his servants the dream, and we will interpret it.”

8 Then the king answered, “I am certain that you are trying to gain time, because you realize that this is what I have firmly decided:

9 If you do not tell me the dream, there is only one penalty for you. You have conspired to tell me misleading and wicked things, hoping the situation will change. So then, tell me the dream, and I will know that you can interpret it for me.”

10 The astrologers answered the king, “There is no one on earth who can do what the king asks! No king, however great and mighty, has ever asked such a thing of any magician or enchanter or astrologer.

11 What the king asks is too difficult. No one can reveal it to the king except the gods, and they do not live among humans.”

12 This made the king so angry and furious that he ordered the execution of all the wise men of Babylon.

13 So the decree was issued to put the wise men to death, and men were sent to look for Daniel and his friends to put them to death.

14 When Arioch, the commander of the king’s guard, had gone out to put to death the wise men of Babylon, Daniel spoke to him with wisdom and tact.

15 He asked the king’s officer, “Why did the king issue such a harsh decree?” Arioch then explained the matter to Daniel.

16 At this, Daniel went in to the king and asked for time, so that he might interpret the dream for him.

17 Then Daniel returned to his house and explained the matter to his friends Hananiah, Mishael and Azariah.

18 He urged them to plead for mercy from the God of heaven concerning this mystery, so that he and his friends might not be executed with the rest of the wise men of Babylon.

19 During the night the mystery was revealed to Daniel in a vision. Then Daniel praised the God of heaven

20 and said:

“Praise be to the name of God for ever and ever;
wisdom and power are his.

21 He changes times and seasons;
he deposes kings and raises up others.
He gives wisdom to the wise
and knowledge to the discerning.

22 He reveals deep and hidden things;
he knows what lies in darkness,
and light dwells with him.

23 I thank and praise you, God of my ancestors:
You have given me wisdom and power,
you have made known to me what we asked of you,
you have made known to us the dream of the king.”

24Then Daniel went to Arioch, whom the king had appointed to execute the wise men of Babylon, and said to him, “Do not execute the wise men of Babylon. Take me to the king, and I will interpret his dream for him.”

25 Arioch took Daniel to the king at once and said, “I have found a man among the exiles from Judah who can tell the king what his dream means.”

26 The king asked Daniel (also called Belteshazzar), “Are you able to tell me what I saw in my dream and interpret it?”

27 Daniel replied, “No wise man, enchanter, magician or diviner can explain to the king the mystery he has asked about,

28 but there is a God in heaven who reveals mysteries. He has shown King Nebuchadnezzar what will happen in days to come. Your dream and the visions that passed through your mind as you were lying in bed are these:

29 “As Your Majesty was lying there, your mind turned to things to come, and the revealer of mysteries showed you what is going to happen.

30 As for me, this mystery has been revealed to me, not because I have greater wisdom than anyone else alive, but so that Your Majesty may know the interpretation and that you may understand what went through your mind.

This passage is interesting to me because it shows the kind of attitude that God answers. The King in this passage was tired of hearing man-made stories from his servants – stories that were undoubtedly influenced by the servants desire to survive the King’s wrath. The servants would only have told the King things that were vague and happy, so that they could never be proved wrong or found to be judgmental or offensive. But the King was tired of that. He wanted someone with authority to tell him the truth about the way the world was.

In the rest of the chapter, Daniel interprets the dream, and concludes by saying this: “The great God has shown the king what will take place in the future. The dream is true and its interpretation is trustworthy.”. The King replies: “Surely your God is the God of gods and the Lord of kings and a revealer of mysteries, for you were able to reveal this mystery.”

I think it is is going to be difficult for Christians living today to be able to tell people their dreams like that. But what we can do is talk about God’s miracles as revealed by science and history. We can study astrophysics, biochemistry and history and we can explain what God did in creating and fine-tuning the universe for life, in sequencing amino acids into functioning proteins, in creating brand new body plans in the Cambrian explosion, in raising Jesus from the dead as a matter of historical record, and so on. We have to show how great God is to people who do not even think he exists, and without assuming that they believe in the Bible. And we have to do it by focusing on what is true. 

Early last week, I got a message from a friend who was interested in a girl that he met on an online dating service. She claimed to be a Christian. My friend explained why he was so interested in some of the evidences I outlined above. She was not impressed. She said “I prefer to show people Christianity is true by not judging them, by being compassionate, by introducing them to a fun and affirming community”. There was no emphasis on truth in her approach. In fact, any religious group could do those things and “establish” their religion as true, by appealing to feelings. But this is clearly not what the God of the Bible intends for people who seek him. He is a God of truth, and truth is established by logical reasoning and supporting evidence.

There are still people out there like the King who are looking for someone who can speak to them with authority. All it takes from us is a little studying, and we can be like Daniel, too. But we have to know what God has done from science and history, and speak with authority about how we can know that God has acted supernaturally. Authority to speak comes from having knowledge about what we are talking about, and knowledge comes from studying and debating with people we disagree with. Nebuchadnezzar  was not a believer in the God of Israel, but he was still interested in truth. That won’t always be the case, but it is the case for some people.

New poll: few Millennials describe belief in God as “very important”

Beliefs of millennials and boomers

I saw a very interesting article that compared the attitudes of young people about things like patriotism, religion, freedom, etc. The numbers are very discouraging.

So, here’s the article from the Washington Examiner:

The importance of patriotism, faith in God, and having children is significantly lower among millennials and Generation Z, compared to previous generations.

In a new poll conducted by the Wall Street Journal and NBC News, nearly 80% of people aged 55-91 said being patriotic is important to them, while only 42% of millennials and Generation Z, or those aged 18-38, said the same. Thirty percent of millennials and Generation Z said religion was important, compared to the over 75% of baby boomers, with just over 30% of millennials and Generation Z saying it was important to have children.

Areas where the younger generations had placed higher importance compared to boomers were tolerance for others and self-fulfillment, with financial security being almost tied between the two age groups.

I’m sure that everyone has seen other polls showing the decline of Christianity, especially in mainline and Catholic churches. Evangelicals are declining less, but they are still declining.

The reason I linked to this post is because I’ve noticed that some Christians don’t really think that there is anything to be concerned about. Everything is working fine, they say. Whatever we’re doing right now must be working, because there is no decline. We’re winning, and if you think otherwise, then you’re just complaining.

Well, I don’t really know why there is this decline, all I can do is speak from my experiences. I’ve met people through my blog who did lose their faith in college, and I’ve met ex-Christians in my office, too. I asked them what the problem was, and it seems to be that when they were growing up, they often bullied into behaving like a Christian without being able to ask any questions about whether it was true. And then as soon as they got to college away from their parents and pastors, they just dumped the whole thing.

I remember listening to an amazing lecture a while back by Dr. Scott Waller. I think it was a lecture he gave for the Stand to Reason “Masters Series in Christian Thought” in 2003. The lecture was about Postmodernism in the University. Postmodernism is the view that there are no true or false views, especially with “soft” issues like religion and morality. In the lecture, he talked about how a father had sent his devout Christian son to university, and the son had returned an atheist after one semester. I remember Dr. Waller quoting the son telling his parents “I have come to think of my time growing up in this house as the dark period of my life”. The father was very upset. So Dr. Waller told him what to do. He said, you’re going to need to read a few books on the most common questions that your son has, and then work through the answers with him. And he made a little pile of books about common questions that college students ask, and pushed the pile across the table to the father. And the father pushed the books back across the table to Dr. Waller, and said “well, I don’t have time for reading so many books… but could you just talk to him instead?”

Another thing that seems to cause a lot of young people to  leave the faith in college is sex. Now if I were trying to convince someone to be responsible about sex, I’d try to show them studies and statistics to explain why there really are best practices to relationships and marriage. For example, I’d might show them that the number of premarital sex partners increases marital instability, or that sliding into cohabitation early tends to make marriages less stable. But this takes a bit of work, and you have to work through it with the young people. I just don’t know if parents really reason with their kids like this. But in churches, I’ve noticed that trying to make an argument using evidence isn’t very popular. To me, if I were trying to be convincing to someone about something, I would use evidence. It’s just natural to me to make a case if I’m trying to be persuasive. But making a case just hasn’t been a really big priority in the churches I’ve attended.

So, I guess if I had to give any advice to parents of children, or pastors in churches, it would be that Christianity is in decline, and we need to do more than just order people to memorize Bible verses and creeds, go to church, etc. It’s hard for me to know what’s really going on in everyone’s home, and in everyone’s church. But I don’t think that whatever we’re doing in our homes and churches is working to convince young people that belief in God is very important.
