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

1 Comment

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.

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.

Should we expect to know what God’s reason is for allowing evil and suffering?

Leave a comment

Here is an article by Steven Cowan about the problems of evil and suffering.

Intro:

The problem of evil is no doubt the most serious challenge to belief in God. Even religious believers find it troubling that evil exists in the world—and so much evil! It is puzzling, to say the least, that an all-powerful, absolutely good being would allow evil to exist in his creation. And yet it does. Evil and suffering exist and they are often overwhelming in their magnitude.

Now let’s find out what a noseeum is, and how it relates to the existence of evil and suffering:

However, perhaps God’s existence is incompatible with a certain kind of evil that exists. For example, the atheist William Rowe has argued that God’s existence is inconsistent with pointless or gratuitous evil. By “pointless evil,” Rowe means evil that does not and cannot serve a greater good. And Rowe believes that there is such pointless evil in the world. He thus concludes that God does not exist. Rowe’s argument may be simply stated as follows:

  1. If God exists, there would be no pointless evil.
  2. There is pointless evil.
  3. Therefore, God does not exist.

[…]But, is there pointless evil in the world? Rowe thinks there is. To show that there is pointless evil, Rowe introduces what he calls the “noseeum inference.” Like the pesty little bugs that some readers may be familiar with, a “noseeum” is something that you cannot see—it is a “no-see-um.” And a noseeum inference is a conclusion drawn on the basis of what one does not see. The basic structure of all noseeum inferences looks like this:

  1. I cannot see an x.
  2. Therefore, there probably is no x.

We all make noseeum inferences everyday of our lives. Every time I go to cross a street, I look both ways and I step out into the street only after I “no-see-um” a car coming.

[…]Rowe applies this kind of noseeum reasoning to God and evil. Rowe suggests that if we cannot see a reason for a particular instance of evil, then there is probably not a reason. Suppose we hear about a very young child who is tortured to death to amuse some psychotic person. We think about this event and we examine all the circumstances surrounding it. No matter how hard we try, we cannot see any good reason why this child had to suffer the way she did. Since we cannot see a reason why God would allow this child to suffer, there probably is not a good reason—the child’s suffering was pointless. Of course, Rowe would be quick to point out that he is not speaking merely hypothetically. There are cases like this in the news every day—real-life cases in which we shake our heads in frustration, wondering why God would allow such a thing.

Is Rowe correct in his conclusion? Do such examples prove that there is pointless evil in the world? I don’t think so. To see why, we must recognize that noseeum inferences are not all created equal. Some noseeum inferences, as we have seen, are reasonable and appropriate. But, many are not. Suppose I look up at the night sky at the star Deneb and I do not see a planet orbiting that star. Would it be reasonable for me to conclude that there is no planet orbiting Deneb? Of course not. Suppose that using the best telescopes and other imaging equipment presently available, I still cannot see a planet around Deneb. I would still be unjustified in concluding that there was no such planet.

In that example, the planet is the noseeum. Just because you look really hard, you can’t be confident that the planet is not there. And similarly with the problem of evil and suffering, looking really hard and finding no reason does not mean that there is no reason. It just means that you are not in a good position to see the reason. You don’t know enough to to be sure that there is no reason, because of your limitations as a human being.

To know that any given instance of evil or suffering is gratuitous/pointless requires a high level of knowledge. How much knowledge? Well, consider this paper by the late William Alston of Syracuse University, who lists six problems with the idea that humans can know that any particular instance of evil and suffering is gratuitous.

According to the paper, human beings just do not have the capability to know for certain that God has NO morally sufficient reason for allowing any particular instance of evil and/or suffering. God’s morally sufficient reason is a noseeum. To know for sure that there is no reason, we would need to have more knowledge than we do.

Also, remember that on the Christian view, the good aim that God has is NOT to make humans have happy feelings in this life, regardless of their knowledge, wisdom and character. That’s what atheists think, though. They think that God, if he exists, is obligated to make them feel happy all the time. They don’t think that God’s goal is being actively involved in forming their knowledge, wisdom and character. God has a purpose – to work in the world so that everyone who can freely respond to him will respond to him. The Bible says that allowing pain and suffering is one of the ways that he gets that group of people who are willing to respond to respond to him – FREELY. To be able to claim that evil is gratuitous, the atheist has to show that God can achieve his goal of saving all the people he wants to save while permitting less suffering in the world. And that is a very difficult thing for an atheist to show, given our human cognitive limitations.

The authors of the gospels of Mark and Luke knew eyewitnesses to the life of Jesus

1 Comment

Were the authors of the gospels of Mark and Luke connected to eyewitnesses to the life of Jesus? Well, it turns out that there are good reasons to think that Mark was linked to the eyewitness Peter, and Luke was linked to Paul, who had a post-mortem appearance of Jesus in 1 Cor 15:8, and who met with Peter and James in Galatians 1 and again in Galatians 2.

There is a list of evidence for Peter’s influence on Mark on the Cold Case Christianity blog.

Here’s my favorite one from the list:

Peter’s Embarrassments Have Been Omitted

There are many details in the Gospel of Mark consistent with Peter’s special input and influence,including omissions related to events involving Peter. How can Mark be a memoir of Peter if, in fact, the book contains so many omissions of events involving Peter specifically? It’s important to evaluate the entire catalogue of omissions pertaining to Peter to understand the answer here. The vast majority of these omissions involve incidents in which Peter did or said something rash or embarrassing. It’s not surprising these details were omitted by the author who wanted to protect Peter’s standing in the Christian community. Mark was quite discreet in his retelling of the narrative (other Gospel writers who were present at the time do, however, provide details of Peters ‘indiscretions’ in their own accounts. See Cold-Case Christianity for a more detailed explanation).

It makes me laugh to imagine Peter looking over Mark’s shoulder and saying “no, don’t put that in it” and “no, don’t tell them I did that”. Funny! But also very good evidence. The rest of Wallace’s list makes it even more clear.

And what about the gospel of Luke? Well, did you know that the author of Luke’s gospel knew Paul? If you read it carefully, you’ll see that Luke switches from describing history from an “I” perspective to describing things from a “we” perspective in the book of Acts (which he also wrote). Who is the “we” he is talking about?

Here’s famous Christian scholar William Lane Craig to explain:

Now who was this author we call Luke? He was clearly not an eyewitness to Jesus’s life. But we discover an important fact about him from the book of Acts. Beginning in the sixteenth chapter of Acts, when Paul reaches Troas in modern-day Turkey, the author suddenly starts using the first-person plural: “we set sail from Troas to Samothrace,” “we remained in Philippi some days,” “as we were going to the place of prayer,” etc. The most obvious explanation is that the author had joined Paul on his evangelistic tour of the Mediterranean cities. In chapter 21 he accompanies Paul back to Palestine and finally to Jerusalem. What this means is that the author of Luke-Acts was in fact in first hand contact with the eyewitnesses of Jesus’s life and ministry in Jerusalem.

[…]There is no avoiding the conclusion that Luke-Acts was written by a traveling companion of Paul who had the opportunity to interview eyewitnesses to Jesus’s life while in Jerusalem. Who were some of these eyewitnesses? Perhaps we can get some clue by subtracting from the Gospel of Luke everything found in the other gospels and seeing what is peculiar to Luke. What you discover is that many of Luke’s peculiar narratives are connected to women who followed Jesus: people like Joanna and Susanna, and significantly, Mary, Jesus’s mother.

Was the author reliable in getting the facts straight? The book of Acts enables us to answer that question decisively. The book of Acts overlaps significantly with secular history of the ancient world, and the historical accuracy of Acts is indisputable.

This has recently been demonstrated anew by Colin Hemer, a classical scholar who turned to New Testament studies, in his book The Book of Acts in the Setting of Hellenistic History. [5] Hemer goes through the book of Acts with a fine-toothed comb, pulling out a wealth of historical knowledge, ranging from what would have been common knowledge down to details which only a local person would know. Again and again Luke’s accuracy is demonstrated: from the sailings of the Alexandrian corn fleet to the coastal terrain of the Mediterranean islands to the peculiar titles of local officials, Luke gets it right.

I know a lot of people (like my Dad) read the Bible devotionally, looking for feelings or trying to “get right with God” so they get blessings. But I think it’s helpful to look at things from an evidential point of view – how am I going to make a case for this? When you look at things from that perspective, the Bible gets a whole lot more interesting. And you can talk about it with non-Christians when you know about these interesting details.
