Physicists must defend the integrity of science

** Written by “Surak” **

German climate scientist, Lennart Bengtsson, is speaking out about the overwhelming pressure he experienced after joining a group skeptical of climate change:

News that Lennart Bengtsson, the respected former director of Germany’s Max Planck Institute for Meteorology, had joined the Global Warming Policy Foundation (GWPF), sent shockwaves through the climate research community. GWPF is most notable for its skepticism about climate change and its efforts to undermine the position of the United Nations Intergovernmental Panel on Climate Change (IPCC). The tremors his decision sent through the scientific community shocked Bengtsson.

The scientist said colleagues placed so much pressure on him after joining GWPF that he withdrew from the group out of fear for his own health. Bengtsson added that his treatment had been reminiscent of the persecution of suspected Communists in the United States during the era of McCarthyism in the 1950s.

It is time for physicists around the world to wake up to what is happening to science. They cannot sit back and do nothing as their colleagues in climate science are being harassed, having their jobs threatened, and being denied the opportunity to publish their works for political reasons. Physicists have to feel and express outrage whenever politicians make nakedly self-serving pronouncements that the scientific debate on climate change is over. Physicists know better than anyone else that’s not how science works. How often during the centuries from Aristarchus to Copernicus to Lemaître have physicists witnessed the lone individual prevail in the search for truth over the mistakes and objections of the multitude?

The threat to science is not confined to the study of climate change. Consider the field of biology, which, since the time of Thomas Huxley, has been dominated by the flawed theory of Darwin. What true scientist could accept the near deification of another scientist or the effective canonization of his works? Physicists certainly venerate the pioneers of astronomy and physics, but they do so even as they attempt to fulfill their scientific responsibility to do everything they can to prove those great scientists wrong. Copernicus, Galileo, and Newton did much for humankind, but physicists don’t try to shield them from criticism. They fully accept and honestly proclaim that these great luminaries were often wrong. By contrast, try getting any biologist to publicly admit the truth that Darwin was seriously wrong about evolution. They don’t dare.

And then there are the behavioral and social sciences—the benighted drudges of left-wing political ideology for so many generations. Take a few moments to investigate the latest pronouncements from the professional associations that represent the mainstream of psychology, anthropology, sociology and all the other behavioral disciplines; you will quickly understand the anti-science they truly represent. Psychologist, William James, was correct when he wrote about the study of human behavior over one hundred years ago, “This is no science … ,” but he was tragically wrong when he continued, “… it is only the hope of a science.”

There is no hope of science in these fields, because in them there is none of the overriding desire for or genuine commitment to truth that can defeat the human failings that physics took two millennia to overcome. That is why the social and behavioral studies have failed to accomplish the paradigm shift, the empirical conversion, and the discovery of natural laws which are the necessary steps to true science. Instead of Copernicus, Galileo, Newton and the light of truth, these fields have give humankind nothing more than scientific abominations such as Karl Marx and Sigmund Freud.

Physicists must understand the terrible and dangerous imbalance in human knowledge their lack of leadership is allowing to occur. Physics and the other physical sciences have given humankind an incredible power over the forces of nature. We can harness nuclear energy, create a multitude of new chemicals, manipulate the building blocks of matter, reshape the surface of the Earth, and change the atmosphere. But, because we do not understand or have any power over the inner forces that cause human behavior, we are like little children handling loaded weapons.

It took 1800 years before Copernicus realized the truth of what Aristarchus said about the structure of our solar system and took the first step toward true science. We can’t wait another 1800 years to develop a true science of human behavior. We won’t last that long. All sciences have to be put back on the path to truth. That’s why physicists must find the courage and determination to act as the keepers of the scientific flame and light the way for the others.

Physicists must shine a scientific light on all of the pretenses, the dishonesty, and the abuses that pass for science in other disciplines. Physicists must turn their love of science into a rage against all efforts to bend science away from the search for truth. Physicists must react with intellectual fury against all attempts to subvert science into the service of greed (yes, I’m talking about you, Al Gore) and the lust for political power (yes, I’m talking about you, IPCC).

Physics is the father and mother of all science. Physicists must act like the loving but determined parents of a hoard of unruly children who, instead of working hard to become real scientists, spend their time playing at and pretending to be scientists in the fields of biology, climate change, and human behavior. Physicists must guide and instruct those who are willing to learn from the magnificent successes of the physical sciences. They must relentlessly call out, scold, and discipline those who aren’t. If physicists lack the foresight or are simply too wimpy to take charge and lead the way, science will fail. Only God can help humanity if that happens, because we won’t be able to help ourselves.

Replay: Politics, science, and a false dichotomy

Traffic’s up after the announcement of the publication of our Astronomy and Astrophysics curriculum, so we’re replaying some of our more important posts from the archives for our new readers.

** Written by “Surak” **

There was a political confrontation last Thursday [August 2011] in New Hampshire between conservative politician, Rick Perry, and a liberal woman protestor. The dispute concerned Perry’s views about evolution and creationism, and it demonstrated why we need to be concerned about the future of science in America. Governor Perry spoke to the woman’s young son in front of the usual swarm of reporters eager for a headline. Perry gave them one by telling the boy that evolution was a theory with gaps in it. In an obvious attempt to contrive an unflattering media incident to hurt the Texas governor’s campaign, the mother could be heard urging the child to ask Perry why he didn’t believe in science. Perry ignored the mother and told the boy that in Texas both evolution and creationism are taught, “… because I figured you’re smart enough to figure out which one is right.” I am appalled by what the mother did and troubled by the implications of Perry’s response.

The mother undoubtedly thinks of herself as a defender of ‘science,’ by which I guess she means the usual vague understanding of the currently popular but failed mid-20th century version of evolution. Whatever her beliefs, it was an abuse of science to pull a cheap political trick like this. And, it was a disturbing corruption of her child’s innocence by putting words in his mouth he couldn’t possibly have understood. She obviously thought she was protecting him and other children from false ideas, but her actions amount to nothing more than a crude form of indoctrination based on the prevailing conviction that any questioning of ‘evolution’ is an intellectual sin.

I do not endorse Rick Perry or his political viewpoints. Having said that, I do agree with two important things he said. First, evolution theory, even in its best, most current form, does have serious gaps. For instance, it cannot explain how life began, the incredible explosion of animal life in the Cambrian, the fossil record that shows the sudden appearance of a multitude of new organ, limbs and species with no apparent transition stages, or the very recent appearance and mysterious nature of human consciousness. One cannot defend science by becoming indignant when someone else points out the obvious.

More importantly, I hope Governor Perry was sincere about trusting students to get it right. Science education in America should be based on that trust in (and challenge for) young minds. The foundation of modern science, as well as the basis of genius, is the ability to ask good questions, usually in the form of ‘how’, ‘why’ and ‘what if.’ Einstein’s thought experiments are a famous example. Scientific questioning, if it is to continue to lead to amazing and useful new answers, should never be shackled by politics, religion, or philosophy. Children must be taught and encouraged to ask their own questions no matter how strange, silly, or politically incorrect they might seem to parents and teachers.

Years ago, my high school science classes consisted mostly of rote memorization of facts and stale reenactments of old experiments. We were forced to think about other people’s questions (including a lot of mind-numbing ‘who’, ‘when’, and ‘where’) rather than our own questions. The whole process was as divorced from real life concerns, important philosophical questions, and religious beliefs as possible, and therefore totally irrelevant and boring. It wasn’t until years later that I discovered the wonders and power of real science.

I have a deep commitment to the scientific method. But, that commitment is tempered by an understanding that science is a tool that has limitations which must be acknowledged. Science cannot continue its positive role in society by becoming some kind of false idol, something created by humans but worshiped as infallible. Scientists and science teachers need to model a necessary and healthy humility that includes the need to state up front that science can only deal with our material world and can have nothing legitimate to say about anything that might lie outside our universe, such as God or heaven. Then maybe we’d get fewer annoying distractions at political events, and politicians could focus more on what they really need to do.

But humility is not happening. Science is being promoted by some as the complete, unerring, and only way to arrive at the truth. So, instead of being a good example for others, we witness more than a few scientists make the grave mistake of denigrating other people’s deepest beliefs and alienating them from science. Look up the latest silly musings of the great scientist Stephen Hawking to see a sad and disturbing example of this. If humility fails on a large enough scale, science can’t help but slide in the direction of political correctness and eventually petrify as dogma.

We won’t be able to avoid this fate if protecting science comes to mean putting young people like the woman’s son in an educational bubble to protect them from philosophy and religion under the guise of separation of church and state. Remember that science started as something called natural philosophy and was given its modern form by its devoutly Christian founders. You cannot separate these three things without damaging science. If our current generation of students is to become the next generation of effective scientists, they must be given the opportunity to understand how science relates to and differs from religion and philosophy objectively without the biases and fears that currently stifle our schools and rupture our communities.

So, Governor Perry is right about teaching creationism, because it is a powerful force in American history and culture that needs to be studied not just in social studies classes but also in science classes. Even young-Earth creationism, which I view as sadly non-scientific, should be squarely presented to high school students. Students need to understand what science is not in order to understand what it is. They will benefit from understanding young-Earth creationism, have fun debating it, and discover the truth for themselves if given the necessary tools, opportunity, and encouragement.

My challenge to the mother and all others on the left of the political spectrum is ‘what are you afraid of?’ If all the variations of creationism are so totally wrong, if the science you believe in is so strong, won’t it be obvious to the vast majority of students by the time they finish high school? Allow creationism, intelligent design, and the various forms of evolutionary theory to contend with one another in an honest competition of ideas, and then trust students to get it right. One can only object to this if his or her real goal is indoctrination.

This open approach to science education would include a spirited defense of Darwinism in the schools, because Darwin is a prime example of a great scientist asking important questions and coming up with an original and compelling answer. But evolutionary theory must be presented truthfully and fully, including not only its strengths, but also its many weaknesses. In the spirit of an open and effective science curriculum, would the liberal mother from New Hampshire be willing to have science teachers discuss the totally unexpected results of evolutionary development (Evo Devo)? Is this ‘defender of science’ even aware that the findings of biologists in this new field have turned evolutionary thought on its head in the last few years? (I refer the reader to Sean B. Carroll’s excellent book, Endless Forms Most Beautiful: The New Science of Evo Devo and the Making of the Animal Kingdom). Would she be willing to have students informed that the three great enduring mysteries of biology – the origins of life, the inexplicable explosion of animal life in the Cambrian, and the sudden development and mysterious nature of human consciousness – correspond to the three instance in Genesis that the word ‘creation’ is used to describe how things came about? (As an agnostic about religion, I’m not sure what this means, but it is really interesting.) Or, would she insist that young people be kept ignorant of all this in defense of some quasi-sacred belief she calls evolution?

To be fair, it is likely and terribly unfortunate that most people on the political right and the Christian side of the science/religion debate don’t trust young people either. As the religious and political conflict continues to intensify, which it seems to be doing, each side will probably do all it can to indoctrinate and control children. I fear that, as a result of this irresolvable conflict, science as the search for truth will eventually be fatally corrupted and seriously diminished as a force for good in people’s lives.

So, I want to say this to people on the left who declare their desire to protect science: you don’t protect science by sanitizing education and excluding other ways of thinking. You must look at yourselves in the mirror and realize that you are just as susceptible to political dogma and metaphysical prejudice as the people you oppose. Quit trying to use science to score political points and undercut Christian influence. In other words, if you have to fight, fight fair and leave science out of it.

To the people on the religious right who want to protect their faith: you can’t protect it by rejecting science or promoting false scientific views, because it will only make you look foolish and alienate your children in this age of science. Young-Earth creationism in particular is self-defeating because it leaves Christian youth vulnerable to the powerful (but false) scientific arguments of prominent atheists who are increasingly successful in turning young people away from faith. You believe, or at least many of you say you believe, that the Bible is true. You also understand that God gave us minds capable of comprehending his works. Won’t both paths, scripture and science, eventually lead to the same truth?

If you doubt this, consider the following quote from Gerald L. Schroeder’s bestselling book, The Science of God:

At the briefest instant following creation all the matter of the universe was concentrated in a very small place, no larger than a grain of mustard. The matter at this time was so thin, so intangible, that it did not have real substance. It did have, however, a potential to gain substance and form and to become tangible matter. From the initial concentration of this intangible substance in its minute location, the substance expanded, expanding the universe as it did so. As the expansion progressed, a change in the substance occurred. This initially thin noncorporeal substance took on the tangible aspects of matter as we know it. From this initial act of creation, from this ethereally thin pseudosubstance, everything that has existed, or will ever exist, was, is and will be formed.

As Dr. Schroeder points out (p. 56), “This … could be a quote from a modern physics textbook.” But in fact it comes from the 13th century biblical scholar, Nahmanides (1194-1270), who was able to anticipate modern science by 700 years using nothing more than a literal interpretation of the Bible. It’s true that the best scientists in the world were not capable of this level of understanding of our universe until after 1965, but science did finally catch up with scripture. Christians must have faith that scripture and science are two paths to the one and only truth, and God intended us to use both. (See Psalms 19:1 and Romans 1:20.)

This is why I am concerned about Governor Perry’s statement. His indirect response to the mother’s attack assumes that either science (in this case, evolution) or Christian scripture (in this case, creationism) is right, that they can’t both be right. Christians must not buy into the imagined conflict between science and faith — there is no inherent schism. I believe both the scientific view of our universe (effectively understood) and the Genesis account of creation (properly understood) are entirely compatible.

You don’t have to be a believer in scripture to accept the possibility there can be more than one path to the truth. It would be wonderful if we could all wish each other well on whichever path each of us chooses and help one another in the search for truth. If we can’t manage that level of good will, then we should at least accept, in the American spirit of freedom, that no one has a right to tell anyone else what to believe. I hope that all Americans will embrace science as the objective search for truth and keep it above the fray, that Christians will not see science as the enemy but will once again become fully involved in the scientific adventure, and that our brothers and sisters on the left will refrain, even if they must see religion as the enemy, from using science as a weapon. Otherwise we will all lose so much.

Saturday morning astronomy news roundup

Black holes of a feather flock together, and this means the popular ‘unification model’ of active galaxies is probably wrong. Virtually all galaxies have a supermassive black hole in the center, but in active galaxies, the black hole is actively feeding on gaseous and stellar material and kicking out a huge amount of energy. The unification model attempted to explain the different types of active galaxies as really the same type of galaxy viewed from different angles, but new results from NASA’s Wide-field Infrared Survey Explorer (WISE) show that active galaxies of one type cluster differently than active galaxies of another type, indicating that the differences are intrinsic.

Astronomers at SETI think we’ll make contact with an alien intelligence within 20 years. This is based on the sheer number of stars in our neighborhood (lots) and the recent discoveries by the Kepler space observatory hinting that at least 70% of the stars in our galaxy have Earth-size-ish planets orbiting around them. If any of those planets have liquid water on them, the conditions may be favorable for life. There are a lot of ‘ifs’ leading to the possibility of intelligent life on other planets, but given the hundreds of billions of stars in our galaxy alone, some astronomers think the odds are pretty good.

Meteor storm!

Tonight is the night!

In the very early morning hours of Saturday, May 24 (or very late tonight, depending on how you look at it), we may be in for one doozy of a show from a never-before-seen Camelopardalid meteor shower. The shower is predicted to be so intense—with up to 200 meteors streaking across the sky per hour—that it’s being referred to as a possible “meteor storm.” The meteor shower is a result of the Earth crossing the trail of debris left by the newly-discovered Comet 209P/LINEAR. The shower should last for hours, since it will emanate from a northern part of the sky (remember, for those in the Northern Hemisphere, the North Star never sets), but the best time to view the show will be between the hours of 1:00 am and 3:00 am CDT on the 24th.

Parade has some tips on how to view the meteor shower.

New supernova observation reveals details about massive dying stars

For the first time, scientists have direct evidence that the biggest and brightest stars die in supernova explosions. The evidence comes in the form of SN 2013cu, a gigantic star that scientists were able to virtually catch in the act of going supernova last year. A new robotic sky survey, called the intermediate Palomar Transient Factory (iPTF) scans the sky for supernova events, alerting astronomers to possible supernovae so they can be observed very soon after they happen. The iPTF caught SN 2013cu soon after it detonated, allowing astronomers to make detailed observation of the dying star. Most of the time, astronomers are not aware of what type of star went supernova once they go off, since — for the last 400 years, anyway — all supernovae we’ve observed have gone off in other galaxies and we don’t tend to catalog the different types of stars in other galaxies.

This is what makes this latest discovery so extraordinary. Astronomers were able to tell from the supernova spectrum, obtained very soon after the detonation, that this particular object was what is called a Wolf-Rayet star (see image above), a huge and hot type of star that is so massive, astronomers weren’t even sure if it would go supernova when it died. This particular star became what is called a Type IIb supernova. Astronomers will use this information to better understand the way massive stars change throughout their lifetimes.

The scientific method and ‘real science’

The following is a comment left by a reader at Vox Popoli about a year ago, in response to another reader who was concerned about the current state of science. I had written the following response with the intention of posting it here, and then forgot about it. Surak is about to offer some commentary on a disturbing development in science that bears on this, so I figured now was a good time to dig it up and post it.

To answer your question as to what ever happened to the scientific method, here’s the shocking truth: Science does not operate according to the scientific method unless there’s a crisis. Never did.

Science, just like every other avenue of human endeavor (why should it be different, honestly?) operates under the thrall of a power structure. Always has.

The scientific method only applies when challenges come up against prevailing paradigms. Then, it is utilized, and don’t be a fool understand that every effort is made, always, to doom the challenger and to favor the prevailing paradigm.

The great merit of the scientific method is that under these rare conditions reason and proof hold sway. But please do not be so foolish as to assume that science is governed by the scientific method on a basis, because it is not.

Science is governed by egos. And nothing more.

It is true in a grand Kuhnian sense that crisis precedes advancement. It is also true that egos are a factor in science. But so what? Science is the triumph of the human mind over ego and a multitude of other human failings—limited perspective, misleading emotions, dominant philosophies that act as closed boxes, and the corrupting effects of the universal desire for fame, fortune, and/or political power. The scientific method is the means by which these frailties are remedied. Since these obstacles to advancements in knowledge will always be with us, there will always be a turbulent interplay between human nature and the pursuit of science.

The key element of the scientific method that keeps it from flying off in the direction of wild, unsubstantiated speculation is the peer-review process. If you want to know if the scientific method is alive and well in any branch of science, simply observe how rigorously the peer-review process is being used. I go through the peer-review process on several levels every time I submit a research paper for publication.

The first hoop I have to jump through is the judgment of the referee assigned by the journal in which I hope to have my paper published. The most important thing the referee does is check how well I have accomplished the observe –> hypothesize –> predict –> test –> theorize part of the process. If the judgment is that my work is scientifically sound, the paper is published. Then the whole body of my profession passes judgment on my work by deciding whether or not to cite my work. At the next level of the peer-review process, decisions are made about which scientists are deserving of funding, tenure, and promotions. At the final level, judgments are made about which work is deserving of awards. The end result of this in physics is a steady advance in knowledge where occasional detours from truth are corrected and dead ends are usually recognized and reversed.

I accept that there are some areas of science in which the scientific method does not currently function as it should. So-called “climate change science” is the most obvious example of science being corrupted by politics, money, and dogma. Surak will have something to say about this soon with regard to a disturbing development in this field. Meanwhile, there is a simple test one can apply in this regard: any time the name Al Gore or the terms “scientific consensus” and “the debate has been settled” are used in regard to any branch of science, it has undoubtedly strayed from the scientific method.

Biology certainly suffers from an ego problem to the extent that it is nearly impossible to get a mainstream biologist to utter the words, “Darwin was wrong about some important things.” He was wrong about some important things, and a paradigm shift is long overdue in the field of evolution. But, it must be acknowledged that a multitude of biologists are doing very good work that is firmly based on the scientific method.

The real test of any field’s application of the method is whether that field petrifies into dogma or if it routinely accepts change. I must speak in defense of my field of physics/astrophysics. It has a long history that includes the initial establishment of the scientific method as well as continuous successful applications of its process. After the Copernican revolution and the invention of precision clocks, experimental methods were sufficiently advanced that it didn’t take all that long to accumulate enough evidence to overthrow old ideas and adopt new paradigms. To name but a very few examples: Newton’s uniting the heavens and the earth under one set of laws, Maxwell’s unification of electricity and magnetism, Poincaré’s relativity of time and space, Planck’s quantum, Hubble’s confirmation of other galaxies and the expanding universe, Einstein’s new view of gravity, Lemaître’s big bang theory, Zwicky’s dark matter, and the supernova teams’ accelerating universe.

You say this is rare, but how often do you think this is supposed to happen? How often can it happen on such a large scale? The Hubble/Lemaître paradigm is an especially important example of the scientific method working as well as it possibly can. Most physicists did not like the idea of a universe with a beginning, but the scientific method is so firmly established in physics that the vast majority of them accepted it once there was sufficient evidence to overcome all reasonable objections. Those who clung to the notion of the eternal universe for reasons of ego and non-scientific concerns were discredited for straying from the scientific path.

The application of the scientific method does not have to be perfect to be functional. My own everyday experience in the field of astrophysics has been that the method sometimes proceeds as the classic observe -> hypothesize -> predict -> test -> theory. But quite often it is something very different: observe -> huh? -> observe -> what the … ?! -> hypothesize -> predict -> test -> getting close to a theory! -> test again -> wait, what? -> OH! -> hypothesize -> test, and so on. As long as it is evidence- and prediction-driven throughout the confusion, that’s good enough.

As for the system being set up to doom the challenger, how else would you have it? That’s the way it should be, as long as this resistance is not rooted in ideology (e.g. “climate change science”). It’s not unlike a court of law, where the presumption should be the innocence of the accused and the burden of proof lies with the accuser.

Egos, admittedly, often get in the way of true science, but on the other hand I doubt science could proceed without them. Scientists will always be fully human and infinitely closer in nature to Captain Kirk than to Mr. Spock. The vast majority of people I work with are truly driven by a desire for truth, but also the competitive hope for recognition and reward (which is why science has always been a traditionally masculine endeavor). And yes, they also have an understandable instinct to protect the fruits of their labor.

The point of all this, do not confuse the inevitable imperfect application of the scientific method for its absence.

Kepler’s resurrected!

Kepler spacecraft

The space observatory
, that is, not the late great astronomer.

NASA is breathing new life into the currently defunct Kepler spacecraft, which was designed to look for Earth-size exoplanets (planets orbiting other stars) in the Milky Way. Partway through its mission, the Kepler spacecraft lost function in two of the four flywheels it uses to orient itself, and, without the ability to steadily point in a given direction, it became effectively dead.

However, NASA scientists have figured out how to use the pressure from the solar wind to stably orient the spacecraft, and it will hopefully resume its mission of searching out the Milky Way for Earth-size planets. The use of the solar wind to stabilize Kepler will limit where the spacecraft can point itself, but it will still be able to collect a lot of meaningful data.

Physicists getting close to turning light into matter

We’re one step closer to having replicators in our homes. Okay, maybe a slight exaggeration, but physicists are on the verge of transforming light into matter. The process involves high-powered laser beams, a slab of gold, super high-speed electrons, and eventually a stream of photons. The whole apparatus can be thought of as a photon collider. Photons are essentially tiny “packets” of light, and it is hoped that a collision of two of these packets of light will produce a pair of subatomic particles — an electron and its anti-matter counterpart, the positron — particles that are far too tiny to be visible to the naked eye.

Physicists already know that the reverse process — a negatively-charged electron colliding with its positively-charged counterpart, the positron — causes the particles to wipe each other out and produce a burst of light, so the opposite reaction should, in principle, work. The process is governed by Einstein’s famous equation, E = mc2, from his Special Theory of Relativity, which says that energy (light) and matter are essentially the same thing. In fact, during the very, very early history of our universe — the first few fractions of a second — the universe was so hot and dense that energy was converting to matter and back again to energy very rapidly, until the universe cooled down enough for energy to finally “freeze out” into matter. The physics governing this is very simple, but it turns out to be rather difficult to create the conditions in a laboratory for this to happen. Thus, the excitement over this latest experiment to create matter from light.

It’s pretty exciting to think I may see Star Trek-like replicators in my lifetime. First thing I’m ordering when I get one? Tea, Earl Grey, hot.

Replay: Heroes sometimes fail: Why Stephen Hawking is wrong

Traffic’s up after the announcement of the publication of our Astronomy and Astrophysics curriculum, so we’re replaying some of our more important posts from the archives for our new readers.

** Written by “Surak” **

As a human being who often struggles with relatively trivial difficulties in life, I have long felt admiration for Stephen Hawking’s courage and determination to continue working in spite of a highly-debilitating disease. As a physics enthusiast, I have the greatest respect for his accomplishments. But now, as a result of an article published in The Guardian two weeks ago [May 2011], I also feel embarrassment for, and disappointment in, Hawking. The article reported his views on religion and metaphysics — they were unoriginal, ill-informed, biased, insensitive, and even arrogant.

The article was entitled, “Stephen Hawking: ‘There is no heaven; it’s a fairy story’.” I don’t believe Hawking is capable of such an inane statement, so I attribute this bit of silliness to the reporter’s desire for an attention grabbing headline. It’s just another example of why no one can trust reporters. Unfortunately the rest of the silliness that follows is undoubtedly Hawking’s.

For example, Hawking believes the human brain is like a computer that will stop working when its components fail. This is an old and discredited view of the human mind. The brain is not like any known computer. For one thing, computers process serially, while the brain has the wonderful ability to process things in parallel. Hawking simply has the metaphor backwards, as any computer engineer struggling to make computers more like the human brain can tell you.

This simplistic view of humans can also be faulted for his apparent ignorance of the related problems of consciousness and mind/body dualism. Consciousness is one of the great unsolved mysteries of the universe, and there are no conscious computers except in movies. Since Hawking doesn’t say anything new about consciousness, his statements about the human condition are pretentious.

The dualist/monist debate about whether or not the mind and brain are the same thing has been raging for about 2,500 years. The best philosophers in the world have failed to resolve the question, something of which Hawking seems unaware, since he takes the monist side and simply dismisses the dualist view without argument. When it comes to philosophical arguments, scientists — even great scientists — need to understand that they have no special privileges.

Hawking was also reported to have said, “There is no heaven or afterlife for broken-down computers; that is a fairy story for people afraid of the dark.” From an uninspired and misleading analogy he leaps into metaphysics with an arrogant disregard for the limitations of science. Science is the study of our material universe, and as such it can have nothing to say about heaven or the afterlife. It is destructive of science for one its best to loudly proclaim scientifically unsupportable and irresponsible conclusions.

Hawking certainly has as much right as any other person to speculate on the great questions of human existence. But, honest inquiry and open communication do not appear to be his intent. Hawking does not acknowledge his lack of expertise in these matters nor does he invite the rest of us to discuss heaven or the after-life as his equals. Instead he engages in a condescending and mean-spirited condemnation of deeply-held religious beliefs. There is no empathy for those who fear the darkness of an existence devoid of genuine love, objective moral truths, and the hope of eternal purpose. His message seems to be ‘here is the way smart people think, and if you think differently, you’re a pathetic dimwit.’

Hawking is blind to the wrong he is doing science. He reportedly told Diane Sawyer that “there is a fundamental difference between religion, which is based on authority, and science, which is based on observation and reason. Science will win, because it works.” There are three parts to this statement, all of which are wrong:

  1. There are at least three relevant definitions of the word ‘authority.’ Hawking is using the word in the following sense:

    The power or right to control, judge, or prohibit the actions of others.This would be a generally accepted definition of religious authority. Hawking certainly has in mind the atheist myth that Christian leaders have over the centuries prohibited scientists in significant ways. The false allegation of Galileo’s persecution by the Catholic Church is a notable example1. The undeniable historic truth is that Christian faith and beliefs were the necessary foundation of modern science.Hawking should keep in mind two other important definitions of authority:An expert in a particular field.The ability to influence or control others.Hawking, as a renowned expert in physics, has significant influence over others — he is a scientific authority. When he uses this sort of authority to make pronouncements that go far beyond the scope of legitimate science, Hawking is the one abusing authority.
  2. I wholeheartedly agree with Hawking that science is largely based on observation and reason. So, what has Hawking observed to lead him to the conclusion there is no afterlife or heaven? Has he teleported to the far reaches of the universe? Has he managed to visit the other seven dimensions that string theory posits to exist? Has he somehow escaped the confines of our universe to see what is outside? Has he at least had a near-death experience? If his beliefs are not based on direct observation, then what exactly does Hawking’s reason tell him that has eluded so many other great thinkers before him?
  3. In what way does science work better than religion? Science gives knowledge of one kind, but it cannot give humankind a viable ethics to live by2or explain the meaning or purpose of life. The Bible does these important things for billions of people. Even for non-Christians, the dominant moral system in the world today has its roots in Christianity, which is the major reason the world has never been safer or more prosperous than it is now.Furthermore, the Bible is arguably superior to science as a source of truth about our universe. Is Hawking aware that the Bible states that the universe had a beginning3, that it was created out of nothing4, and that time in our universe is relative5? Scientists didn’t figure any of this out until the 20th century. Genesis 1 alone makes at least 26 scientifically testable statements about the creation of the universe and the origins of life. All 26 are consistent with current scientific understanding and in the correct order. The inconvenient truth for atheists is that the Bible somehow beat science to important truths by about 3,000 years.

    Science works in an important but very narrow sense — it assists humankind in understanding and controlling much of the natural world. But it also gives people tremendous destructive power. Without religion to give people direction in the choices they make about using that power, humankind could end up destroying itself.Finally, if you compare societies around the world in regard to which works best, science or religion, one fact of supreme importance will jump out at you. Generally speaking, non-religious peoples are not reproducing themselves while religious ones are. This single aspect of a society overrules all others; if a nation doesn’t reproduce itself, it is irrelevant how many other wonderful qualities it may have because they won’t be projected into the future. In the long run, atheist or secular humanist societies, no matter how scientific, don’t work because they lack the power to continue.

Hawking goes on to say that the concept of religion is in constant conflict with his life’s work — science, and understanding the most basic ways in which the universe works — and it’s almost impossible to reconcile the two. The first part of this statement is an old atheist lie: there is no inherent conflict between Christianity and science. Hawking either ignores or is ignorant of the historical fact that the Christian faith and beliefs made science possible in the first place. If you doubt this, take a look at when and where modern science developed and flourished, along with the religious beliefs of the great scientists who laid the foundations of science.

This is not to say that there hasn’t been conflict between science and religion, but it’s not the fault of Christianity. From at least the time of Darwin, secular humanists such as Thomas Huxley have misused science and misrepresented Christian beliefs in an effort to undermine the influence of Christian faith. The truth is that some scientists are in constant conflict with religion because of their atheist beliefs, and they betray science as a result.

The report reminds the public of Hawking’s position that it is “not necessary to invoke God … to get the universe going.” He has maintained this position since very early in his career, telling German news-magazine Der Speigel in 1988 that “what I have done is to show that it is possible for the way the universe began to be determined by the laws of science. In that case, it would not be necessary to appeal to God to decide how the universe began.”

He’s not saying that he knows the cause of the Big Bang. He is saying that he has constructed a mathematical model of a possible explanation. To say something is possible is meaningless and useless. It’s possible that somewhere in the universe, blue gooses lay gold coins with Hawking’s likeness on them. Like Hawking’s statement, it’s not scientific, because no one can prove it’s not true. The other weakness of his argument against the necessity of God is that it requires the laws of nature to be eternal. They would have had to ‘predate’ the universe in some manner that can never be scientifically proved, such as the emerging atheist myth of the multiverse.

Hawking continues, “This doesn’t prove that there is no God, only that God is not necessary.” Hawking is at least aware that science cannot be used to prove that God does not exist. Instead, he engages in the weasel argument that there is effectively no God since anything that is not necessary can be ignored or discarded. It’s like a child denying the necessity of parents. Child to parent: “I’m not saying you don’t exist, you just aren’t necessary. I can live without you, so just give me the keys to the house and the car along with your credit card, and go away and leave me alone.”

Scientists such as Hawking and Richard Dawkins start from a bias against God and then play in a child-like way with concepts to justify their prejudice. Just as a child cobbles together some rough approximation of an airplane out of Lego, Hawking imagines that he has constructed a viable worldview that doesn’t rest on the notion of God. But he has explained nothing and ignored almost everything of significance. He has his mathematical model of a godless universe; don’t bother him with the mysteries of what came before the Big Bang, the origins of life, the sudden Cambrian explosion of animal life, the nearly universal human need for spiritual beliefs, or the greatest mystery of all, the origin and meaning of human consciousness. He has his toy and wants to show it off.

Then Hawking says something that gives an important insight into the workings of the atheist mind. The report continues, “And it’s his work that keeps him going — even if there isn’t a heaven.” “I’m in no hurry to die. I have so much I want to do first.” This statement illustrates the most telling and annoying aspect of atheism: atheists seem incapable of taking any of their beliefs and reasoning to necessary and obvious conclusions. They dismiss God and the afterlife, argue that the material world is all that exists, assert that man is the measure of all things, and conclude that people can free themselves of religious restrictions and do whatever they want. If you ask them to continue with this train of thought, they usually make some kind of vague statement about a life in the service of humankind and the possibility of a kind of immortality in the sense that society will remember a person’s good deeds ‘forever.’

The problem, of course, is that it is delusional nonsense. What any good scientist should know is that our material universe is very likely heading toward what is called heat death, a state in which energy no longer exists in a form that can support life. But even before this occurs, the human species will have become extinct anyway. What is the point of doing anything in this life when you will be annihilated in the blink of a cosmic eye followed in short order by the rest of humankind? If atheists really believed this, they would either commit suicide or become Buddhist monks. But the vast majority of them continue to act as if human existence has some kind of meaning greater than that of their material state. If Hawking is right about God and the afterlife, every trace of humanity will be destroyed, all of Hawking’s work will be lost, and every effort he makes will be futile.

What he is really means when he says he is in no hurry to die is that he values his existence and he wants to keep on existing. He feels he has purpose, but he does not wonder where that purpose could possibly come from. He’s not thinking his own position to its logical end, which is that without God his existence is pathetically finite and ultimately meaningless. He says there is no God, but acts as if there is.

Interestingly, Hawking has also made headlines in recent years over his views about the existence of aliens, and what interactions between our races would be like. “If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans,” he said.

Here we detect the pessimism that will always be a result of atheism (as well as a lack of imagination based on what little he thinks he knows about the past). Without God and the hope for the redemption of humankind, he has no reason for optimism, no belief that things will work out better in the future than in the past. Christians believe this because they believe that good is stronger than evil, that by following God’s direction people can always triumph over evil, and that good therefore must be the future of humankind. That’s why, for instance, evangelical Christians, not atheists, put an end to the worldwide slave trade; that’s why Christians, not atheists, marched into horrendous Civil War battles singing, “He died to make men holy, let us die to make men free,” and ended slavery in America.

In spite of all this, I still believe Stephen Hawking is a hero. He has persevered with a debilitating disease and done tremendous work in theoretical physics. But what do you do when a hero lets you down? There’s a line from the Gordon Lightfoot song, “If You Could Read My Mind,” that goes “The hero would be me. But heroes often fail …” That’s what I think about Stephen Hawking. When it comes to religion and metaphysics, he has failed, but he is still a hero in a way that does not diminish the meaning of the word.

I came to believe in God because of what I learned about the universe. I had the good fortune not to go to Oxford and be saturated with humanist bias against the “God hypothesis.” When I look at the structure of the universe and life on Earth, I see evidence of a great mind at work. I am sorry for Hawking that he can’t.

Saturday morning astronomy news roundup

Scientists are concerned that Earth bacteria are hardy enough to survive the trip to Mars aboard spacecraft and possibly colonize the Red Planet. Scientists at NASA’s Jet Propulsion Laboratory simulated the conditions that the bacteria would be exposed to, both on Mars and in space, and found that some of the spores survived for 18 months—twice the time it takes spacecraft to get to Mars. From a biblical perspective, this is not all that surprising. As ancient biblical commentators pointed out, the universe was created with the potential for life built into it—and as Hugh Ross has explained in great detail in his many books, the universe is undeniably tuned for life. It makes sense that the most basic forms of life would be hardy enough to survive the otherwise harsh conditions beyond the Earth.

Scientists at MIT have created a simulation of the universe that begins from just 12 million years after the Big Bang to now. (Twelve million years may sound like a long time, but in terms of the ~14 billion-year age of the universe, it’s not long at all.) Such simulations are carried out on supercomputers, as they would otherwise take thousands of hours to process on ordinary desktop computers. This newest simulation is an improvement on previous cosmological simulations, because, among other things, it more faithfully produces the mixed population of galaxies observed in the universe, including graceful spirals like our Milky Way, and giant ellipticals like M87, and captures the present-day proportion of hydrogen and heavier elements in galaxies. The universe, itself, is the greatest laboratory ever created, but we are limited in our ability to “experiment” with it. In order to learn about the structure of the universe and the way it has changed with time, scientists have to create simulations and see how well they match up with observations of the universe on different scales of both size and time.
