J. Warner Wallace: science and the Bible agree on creation of the universe

I always recommend that Christians who want to make a positive case for Christian theism begin with the evidence that caused scientists to accept that the universe had a beginning. I don’t recommend stating the kalam argument, or any Bible verses, or any philosophical arguments. Instead, I recommend that they tell the story of how the evidence that led up to the discovery of the Big Bang cosmology was discovered. Who made the discoveries of the evidence, what was the evidence, when was it discovered, and how was it discovered.

Here’s Wallace’s post on it.

Excerpt:

The Second Law of Thermodynamics

This law (also known as the Law of Increased Entropy) recognizes the following: While the quantity of energy within a closed, isolated system (like the Universe) remains the same, the amount of usable energy deteriorates gradually over time. “Usable energy is inevitably used for productivity, growth and repair. In the process, usable energy is converted into unusable energy. Thus, usable energy is irretrievably lost in the form of unusable energy.”

Many of us have played with wind-up toys over the years. After toys of this nature are wound, there is a limited period of time in which we can enjoy them. Within a few seconds, wind-up toys slow down and stop; they run out of energy. Imagine walking into an empty room and discovering a wind-up toy sitting on the floor, still operating (unwinding). The discovery of this toy (and the fact it is still in the process of unwinding), would raise two reasonable inferences: (1) the toy was recently wound at a fixed point in the not-too-distant past, and (2) there was an adequate cause responsible for the initial winding. In other words, you would start looking for the “winder” somewhere in the room, given the fact the toy was still in the process of unwinding. We happen to be living in a “wind-up” universe slowly losing its usable energy. If the universe had no beginning and was infinitely old, why would there be any usable energy still available to us? The fact there is still usable energy in the universe points to a beginning in which the universe was tightly wound, and causes us to look for the cause responsible for such winding.

The Expansion of the Universe
Over the years, a number of scientists have calculated or observed the expansion of the universe. In 1905, Albert Einstein developed the Special Theory of Relativity involving measurements of length, velocity and time from moving observers. These equations led to the now famous E = mc2 equation, which describes how matter and energy can be converted from one form to another. In 1915, by applying relativity to Newtonian physics, Einstein derived the equations of general relativity which describe the relationships between gravity, the speed of light, mass, and other factors in regard to the universe as a whole. His work was consistent with an expanding universe. While this conclusion was initially troubling to Einstein, other mathematicians and scientists were coming to the same conclusion.

Alexander Friedman, a Russian mathematician working in the 1920’s with Einstein’s theories, used the mathematics to prove the universe is expanding. His work was being paralleled at the time by astronomers in Belgium who independently came to the same conclusion. An astronomer named Vesto Slipher presented findings at an obscure astronomy meeting in 1914 which showed that several ‘nebulae’ were receding away from the earth. A graduate student named Edwin Hubble was in attendance and realized the implications. Hubble later proved that these nebulae were actually galaxies, composed of billions of stars. In 1929 he proposed the law of red shifts. Galaxies which are moving away from the earth demonstrate emission spectra with bands shifted toward the red end of the spectrum, and Hubble observed these distant galaxies demonstrated this red shift phenomena. In essence, he proved by observation the universe is indeed expanding.

Our universe is expanding like a balloon. Imagine individual galaxies drawn on the balloon’s surface. As the edge of the balloon expands, the edge galaxies move away from center and away from each other. This is what we are seeing in our universe today. If we could go back in time and reverse the process (“deflate the balloon”), we would eventually arrive at an initial point of convergence. Once again, the science demonstrates our universe had a beginning.

The Radiation Echo
In 1964, two American physicists and radio astronomers, Arno Allan Penzias and Robert Woodrow Wilson, happened upon an important discovery. They were unable to eliminate the radio signal “noise” from their large antenna at the Bell Telephone Laboratories in New Jersey, regardless of where in the universe they tried to point their instrument. As a result, they began to consult with colleagues to determine the cause of this background noise. Phillip James Edwin Peebles, a physicist and theoretical cosmologist at Princeton University, suggested the noise might not be from the antenna at all. Instead, he proposed they might be detecting the residual “background radiation” caused when the universe first came into being. Penzias and Wilson pursued this line of investigation and confirmed Peebles’ suspicions. Numerous additional experiments and observations have since established the existence of cosmic background radiation (culminating in data from the Cosmic Background Explorer satellite launched in 1989). For many scientists, this discovery solidified their belief the universe had a beginning at a fixed point in the past.

Wallace gets these evidences from a book by famous agnostic astornomer Robert Jastrow, former head of the NASA Goddard Space Institute. The book is called “God and the Astronomers”. I have the second edition.

Wallace is working on a new book. Not much is known about it, but based on photos of the books he is reading, it’s something to do with cosmology. If he can write a book for Christians that’s as easy to read as his “Cold Case Christianity”, then we are really going to gain some ground in the culture. The more Christians understand the science of cosmology, the more likely the culture as a whole is going to be to respect the Creator and Designer of the universe.

Physicist Frank Tipler on the usefulness of refereed journals, then and now

I really enjoyed this episode of the ID the Future podcast.

Description:

Is the only good science peer-reviewed science? Are there other avenues to present important scientific work? On this episode of ID The Future, Professor of Mathematics Dr. Frank Tipler discusses the pros and cons of peer review and refereed journals. More than fifty peer-reviewed papers discussing intelligent design have been published, but critics of the theory still proclaim a lack of peer-reviewed work as an argument. Listen in as Tipler shows how things have changed with the peer review process and what we can do about it.

About the speaker:

Frank Tipler was born and raised in Andalusia, Alabama. His first science project was a letter written in kindergarten to Werner von Braun, whose plans to launch the first earth satellite were then being publicized. Von Braun’s secretary replied, regretting he had no rocket fuel for Tipler as requested. By age five, he knew he wanted to be an astrophysicist. But he’s always been a polymath, reading widely across disciplines and into the history of science and theology. After graduating from MIT and the University of Maryland, he did postdoctoral work at Oxford and Berkeley, before arriving at Tulane in 1981.

Whenever William Lance Craig often cites a book by two physicists named “Barrow and Tipler” called “The Anthropic Cosmological Principle” (Oxford University Press, 1988) in his debates to support the fine-tuning argument.  This Tipler is that Tipler! Dr. Tipler is a master of the physics of cosmology and fine-tuning. However, I definitely disagree with him on some of his ideas.

The MP3 file is here. (17 minutes)

Topics:

  • the changing nature of refereed journals and peer-review
  • previously, the refereed journals were more about communication
  • now, ideas are not taken seriously unless they are published in these journals
  • the problem is that referees can be motivated by ideological concerns
  • before, an obscure patent official named Einstein submitted a physics paper and it was published
  • now, an uncredited person would not be able to have a brilliant paper published like that
  • today, there are so many scientists that many more papers are submitted
  • although it restricts BAD ideas, it can also end up censoring NEW ideas
  • the problem is that any really brilliant idea has to go against the prevailing consensus
  • peer-review may actually be holding back the progress of science by censoring NEW ideas
  • some referees are motivated to censor ideas that undercut their reputation and prestige
  • Dr. Tipler was told to remove references to intelligent design before one of his papers would be published
  • how scientists with NEW ideas can bypass the system of refereed journals when they are censored
  • peer-review has value when it finds errors, but not when it suppresses new ideas

I think this one is a must listen. As much as I like peer-reviewed research, it’s important to acknowledge the limitations. I think if you’re going into a debate, you definitely want to be the one with the peer-reviewed evidence. Let the other guy be the one making assertions and stating his preferences and opinions. But that doesn’t mean that the peer-review process can’t be improved – I think that it can be improved.

Here is a listing of some recent peer-reviewed publications related to intelligent design.

Four ways that the progress of science conflicts with naturalistic speculations

When people ask me whether the progress of science is more compatible with theism or atheism, I offer the following four basic pieces of scientific evidence that are more compatible with theism than atheism.

Here are the four pieces of evidence best explained by a Creator/Designer:

  1. the kalam argument from the origin of the universe
  2. the cosmic fine-tuning (habitability) argument
  3. the biological information in the first replicator (origin of life)
  4. the sudden origin of all of the different body plans in the fossil record (Cambrian explosion)

And I point to specific examples of recent discoveries that confirm those four arguments. Here are just a few of them:

  1. An explanation of 3 of the 6 experimental evidences for the Big Bang cosmology (From an article from Caltech)
  2. Examples of cosmic fine-tuning to allow the existence of conscious, embodied life (From the New Scientist)
  3. Evidence that functional protein sequences are beyond the reach of chance, (from Doug Axe’s JMB article)
  4. Evidence showing that Ediacaran fauna are not precursors to the Cambrian fossils, (from the journal Nature)

Atheists will typically reply to the recent scientific discoveries that overturned their speculations like this:

  1. Maybe the Big Bang cosmology will be overturned by the Big Crunch/Bounce so that the universe is eternal and has no cause
  2. Maybe there is a multiverse: an infinite number of unobservable, untestable universes which makes our finely-tuned one more probable
  3. Maybe the origin of life could be the result of chance and natural processes
  4. Maybe we will find a seamless chain of fossils that explain how the Cambrian explosion occurred slowly, over a long period time

Ever heard any of these responses?

Below I list some resources to help you to respond to the four responses of atheists to the experimental data.

1) The Big Crunch/Bounce has been disproved theoretically and experimentally.

Theoretically:

The impossibility of a bouncing universe

ALAN H. GUTH* & MARC SHER†

*Center for Theoretical Physics, Laboratory for Nuclear Science and Department of Physics, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA

†Department of Physics, University of California, Irvine, California 92717, USA

Petrosian1 has recently discussed the possibility that the restoration of symmetry at grand unification in a closed contracting Robertson–Walker universe could slow down and halt the contraction, causing the universe to bounce. He then went on to discuss the possibility that our universe has undergone a series of such bounces. We disagree with this analysis. One of us (M.S.) has already shown2 that if a contracting universe is dominated by radiation, then a bounce is impossible. We will show here two further results: (1) entropy considerations imply that the quantity S (defined in ref. 1 and below), which must decrease by ~1075 to allow the present Universe to bounce, can in fact decrease by no more than a factor of ~2; (2) if the true vacuum state has zero energy density, then a universe which is contracting in its low temperature phase can never complete a phase transition soon enough to cause a bounce.

Experimentally:

The universe is not only expanding, but that expansion appears to be speeding up. And as if that discovery alone weren’t strange enough, it implies that most of the energy in the cosmos is contained in empty space — a concept that Albert Einstein considered but discarded as his “biggest blunder.” The new findings have been recognized as 1998’s top scientific breakthrough by Science magazine.

[…]The flood of findings about the universe’s expansion rate is the result of about 10 years of study, said Saul Perlmutter, team leader of the Supernova Cosmology Project at Lawrence Berkeley National Laboratory.

Perlmutter and others found such a yardstick in a particular kind of exploding star known as a Type 1A supernova. Over the course of several years, the astronomers developed a model to predict how bright such a supernova would appear at any given distance. Astronomers recorded dozens of Type 1A supernovae and anxiously matched them up with redshifts to find out how much the universe’s expansion was slowing down.

To their surprise, the redshift readings indicated that the expansion rate for distant supernovae was lower than the expansion rate for closer supernovae, Perlmutter said. On the largest scale imaginable, the universe’s galaxies appear to be flying away from each other faster and faster as time goes on.

“What we have found is that there is a ‘dark force’ that permeates the universe and that has overcome the force of gravity,” said Nicholas Suntzeff of the Cerro Tololo Inter-American Observatory, who is the co-founder of another group called the High-z Supernova Search Team. “This result is so strange and unexpected that it perhaps is only believable because two independent international groups have found the same effect in their data.”

There has only been one creation of the universe, and the universe will never reverse its expansion, so that it could oscillate eternally. That view is popular, perhaps in part because many people watched videos of Carl Sagan speculating about it in public school classrooms, but all it was was idle naturalistic speculation, (Sagan was a naturalist, and held out hope that science would vindicate naturalism), and has been contradicted by good experimental science. You should be familiar with the 3 evidences for the Big Bang (redshift, light element abundances (helium/hydrogen) and the cosmic microwave background radiation. There are others, (radioactive element abundances, second law of thermodynamics, stellar lifecycle), but those are the big three. Point out how the experimental evidence for the Big Bang has piled up, making the problem even worse for the eternal-universe naturalists.

2) The multiverse has not been tested experimentally, it’s pure speculation.

Speculation:

Multiverse thinking or the belief in the existence of parallel universes is more philosophy or science fiction than science. ”Cosmology must seem odd to scientists in other fields”.

George Ellis, a well-known mathematician and cosmologist, who for instance has written a book with Stephen Hawking, is sceptical of the idea that our universe is just another universe among many others.

A few weeks ago, Ellis, professor emeritus of applied mathematics at the University of Cape Town, reviewed Brian Greene’s book The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos (Knopf/Allen Lane, 2011) in the journal Nature. He is not at all convinced that the multiverse hypothesis is credible: ”Greene is not presenting aspects of a known reality; he is telling of unproven theoretical possibilities.”

According to professor Ellis, there is no evidence of multiverses, they cannot be tested and they are not science.

Ellis is not the only multiverse sceptic in this universe. A few months ago, science writer John Horgan wrote a column in Scientific American, expressing his doubt in multiverses.

When you get into a debate, you must never ever let the other side get away with asserting something they have no evidence for. Call them on it – point out that they have no evidence, and then hammer them with evidence for your point. Pile up cases of fine-tuning on top of each other and continuously point out that they have no experimental evidence for their speculations. Point out that more evidence we get, the more cases of fine-tuning we find, and the tougher the problem gets for naturalists. There is no evidence for a multiverse, but there is evidence for fine-tuning. TONS OF IT.

3) Naturalistic theories for the origin of life have two problems: can’t make the amino acids in an oxydized atmosphere and can’t make protein and DNA sequences by chance in the time available.

Building blocks:

[…]These results suggest that outgassing of Earth’s interior later than ~200?Myr into the history of Solar System formation would not have resulted in a reducing atmosphere.

Estimating the prevalence of protein sequences adopting functional enzyme folds.

Proteins employ a wide variety of folds to perform their biological functions. How are these folds first acquired? An important step toward answering this is to obtain an estimate of the overall prevalence of sequences adopting functional folds.

[…]Starting with a weakly functional sequence carrying this signature, clusters of ten side-chains within the fold are replaced randomly, within the boundaries of the signature, and tested for function. The prevalence of low-level function in four such experiments indicates that roughly one in 10(64) signature-consistent sequences forms a working domain. Combined with the estimated prevalence of plausible hydropathic patterns (for any fold) and of relevant folds for particular functions, this implies the overall prevalence of sequences performing a specific function by any domain-sized fold may be as low as 1 in 10(77), adding to the body of evidence that functional folds require highly extraordinary sequences.

So atheists are in double jeopardy here. They don’t have a way to build the Scrabble letters needed for life, and they don’t have a way to form the Scrabble letters into meaningful words and sentences. Point out that the more research we do, the tougher the problem gets to solve for naturalists, and the more it looks like an effect of intelligence. Write out the calculations for them.

4) The best candidate to explain the sudden origin of the Cambrian era fossils was the Ediacaran fauna, but those are now recognized as not being precursors to the Cambrian fossils.

Science Daily reports on a paper from the peer-reviewed journal Science:

Evidence of the single-celled ancestors of animals, dating from the interval in Earth’s history just before multicellular animals appeared, has been discovered in 570 million-year-old rocks from South China by researchers from the University of Bristol, the Swedish Museum of Natural History, the Paul Scherrer Institut and the Chinese Academy of Geological Sciences.

[…]This X-ray microscopy revealed that the fossils had features that multicellular embryos do not, and this led the researchers to the conclusion that the fossils were neither animals nor embryos but rather the reproductive spore bodies of single-celled ancestors of animals.

Professor Philip Donoghue said: “We were very surprised by our results — we’ve been convinced for so long that these fossils represented the embryos of the earliest animals — much of what has been written about the fossils for the last ten years is flat wrong. Our colleagues are not going to like the result.”

Professor Stefan Bengtson said: “These fossils force us to rethink our ideas of how animals learned to make large bodies out of cells.”

The trend is that there is no evolutionary explanation for the body plans that emerged in the Cambrian era. If you want to make the claim that “evolution did it”, then you have to produce the data today. Not speculations about the future. The data we have today says no to naturalism. The only way to affirm naturalistic explanations for the evidence we have is by faith. But rational people know that we need to minimize our leaps of faith, and go with the simplest and most reasonable explanation – an intelligence is the best explanation responsible for rapid generation of biological information.

Conclusion

I do think it’s important for Christians to focus more on scientific apologetics and to focus their academic careers in scientific fields. So often I look at Christian blogs, and I see way too much G. K. Chesterton, Francis Chan and other untestable, ineffective jibber-jabber. We need to bring the hard science, and stop making excuses about not being able to understand it because it’s too hard. It’s not too hard. Everyone can understand “Who Made God?” by Edgar Andrews – start with that! Then get Lee Strobel’s “The Case for a Creator“. That’s more than enough for the average Christian on science apologetics. We all have to do our best to learn what works. You don’t want to be anti-science and pro-speculation like atheists are. I recommend reading Uncommon Descent and Evolution News every day for a start.
