Some background for each of the debaters [h/t PQ Exchange]:

More support for the existence of dark energy

The case for dark energy is looking stronger, thanks to new results from the recently-installed Wide Field Camera 3 instrument aboard the Hubble Space Telescope. Dark energy has been hypothesized as the mysterious force causing the expansion of the universe to speed up, but competing models suggest other reasons for the accelerated expansion. A leading competitor is a bubble model that suggests our Milky Way galaxy sits at the center of a relatively sparse region of the universe, and the resulting weaker gravity is causing our local “bubble” to expand more rapidly than the universe as a whole. However, astrophysicists at the Space Telescope Science Institute claim that refined measurements made with the WFC3 have ruled out the bubble model, which predicts a different expansion rate than what is observed.

There are philosophical objections to the bubble model, as well. Ever since Copernicus put forth his Sun-centered model of the solar system, scientists have tended to reject the notion that we occupy any special place in the universe. A model that requires Earth-observers to be at the center of a cosmic bubble makes us a little too special for comfort for most scientists. This alone doesn’t disprove the model (we must never be locked into a conclusion by our philosophy), but it can certainly offer guidance. Adam Riess, head of the research team publishing the new results, comments,

“I know that a lot of people have not taken that theory very seriously because of a major problem with it,” he said. “We tend to believe theories where we don’t live in any special place in the universe. That would be very strange – why should we be in a special place?”

Now that scenario is even less likely to be true, Riess said.

“But on the other hand, dark energy’s pretty weird too,” he said.

Every revolutionary idea in science seems weird at first. If the dark energy model survives the rigors of scientific testing, people a hundred years from now probably won’t find it any weirder than we find the electromagnetic theory of light.

But you look so … old

Galaxy cluster CL J1449+0856 (Credit: ESO)

When I turned 40 recently, people kindly told me, “But you still look young.” So, what do you tell someone who is young but looks old? This is my brilliant segue into a description of a strange discovery by astronomers who observed a galaxy cluster that’s only three billion years old but looks much older. Here’s a neat vid showing its location in the sky (but don’t bother looking for it tonight unless you’ve got a world-class telescope):

Galaxy clusters are the main structures of the universe. A single cluster can contain thousands of galaxies, all gravitationally bound to each other. Because this particular cluster is so far away, astronomers are seeing it as it was when it was very young. (The idea in astronomy is that the further away you look in space, the earlier in time you’re observing the universe. That’s because light, although extremely fast, travels at a finite speed.) Astronomers therefore expected to see typical signs of youth in the cluster — stars actively forming in the galaxies and very little hot, X-ray emitting gas. Instead, what they observed was an older population of stars with very little star formation, and a significant amount of X-ray emitting gas, which usually takes time to accumulate and get trapped in the cluster. Astronomer Raphael Gobat comments, “Such clusters are expected to be very rare according to current theory, and we have been very lucky to spot one. But if further observations find many more, then this may mean that our understanding of the early universe needs to be revised.”

That’s how science works. Observe, hypothesize, observe, theorize, observe, revise … .

When philosophy dominates science

** Written by “Surak” **

Dr. Robb Wilson, who blogs at The Scholar Redeemer, commented on my article “Separating philosophy from science,” and made the following important points:

“good science is NOT aphilosophical”

“a blanket statement that philosophy corrupts science is misleading … there is a philosophy at the root of methodological naturalism as well.”

In light of his excellent comment, I would like to take another shot at what I intended to say.

Ancient Greek philosophy was indeed the solid and necessary foundation on which the first scientific efforts took place, and it was the Judeo-Christian worldview that made modern science possible. I fully accept that whenever and wherever the dominant philosophy/religion of the day acted as a rational foundation on which something higher and broader could be constructed, science flourished. But sometimes the dominant worldview has included beliefs that act like confining walls and a low ceiling on science. The most obvious example is the ancient belief that the Earth was the center of the universe, which helped delay modern science by about 1,800 years.

The point I wanted to make in my original article is that there is today a philosophy that dominates most Western centers of learning, and elements of that philosophy threaten to delay desperately-needed scientific advances in fields such as biology, medicine, psychology, and social behavior. My fears seem to be confirmed by an article published in the February 7, 2011 online edition of the New York Times, titled “Social Scientist Sees Bias Within” by John Tierney. The article quotes Jonathan Haidt, a social psychologist at the University of Virginia, regarding what he describes as a liberal bias in his field:

“This is a statistically impossible lack of diversity,” Dr. Haidt concluded, noting polls showing that 40 percent of Americans are conservative and 20 percent are liberal. In his speech and in an interview, Dr. Haidt argued that social psychologists are a “tribal-moral community” united by “sacred values” that hinder research and damage their credibility — and blind them to the hostile climate they’ve created for non-liberals.

While Tierney and Haidt appear to see the problem largely in political terms as part of a liberal vs. conservative struggle, the root of the problem for this branch of science is really philosophical because the “sacred values” cited by Dr. Haidt are those of humanism.  Our original article on ‘transcranial magnetic stimulation’ was an attempt to demonstrate that a similar philosophical problem exists in biology.

There is also evidence that humanist dominance is causing severe problems in the field of anthropology, for example, the controversial decision last year by the American Anthropological Association to remove the word “science” from an official statement of its long-range plan. The problem extends to general psychology, as well. In their 2005 book, Destructive Trends in Mental Health: The Well-Intentioned Path to Harm, Rogers H. Wright and Nicholas A. Cummings identify some distressing developments in behavioral science. In the preface they include the following statements:

Why, after decades of fighting to establish the rightful role of professionalism in psychology, do we now question the validity and integrity of some of the prevalent practices in our profession? The answer is simple: psychology and mental health have veered away from scientific integrity and open inquiry, as well as from compassionate practice in which the welfare of the patient is paramount.

These taboo topics typically unleash a silencing array of unwarranted charges ranging from political incorrectness, insensitivity, and lack of compassion to (in the extreme) bigotry. We are troubled that disciplines such as psychology, psychiatry, and social work, which pride themselves on diversity, scientific inquiry, intellectual openness, and compassion for those who need help, have created an atmosphere in which honest, albeit controversial, points of view are squelched.

We decry the extremism on the right, but we do not address it in this volume because that is not the problem within organized mental health today. Psychology, psychiatry, and social work have been captured by an ultraliberal agenda, much of which we agree with as citizens. However, we are alarmed with the damaging effect it is having on our science, our practice, and our credibility.

It [American Psychological Association] is no longer perceived as an authority that presents scientific evidence and professional facts. The APA has chosen ideology over science, and thus diminished its influence on the decision makers in our society.

Within the profession of psychology there is currently debate over treatment techniques and interventions that have not been scientifically validated.

It is obvious that we need a greater diversity of ideas and a counterbalance to the prevailing ideologies within mental health circles today. … We must broaden the debated by reducing the ridicule and intimidation of ideas contrary to the thinking of the establishment in the field of psychology.

Once again, the ultra-liberalism identified by the authors is best understood as the political manifestation of a relatively new philosophical orthodoxy, and the indisputable truth is that humanism is the philosophy that dominates many if not most universities and colleges in America today. I believe a strong case can be made that some humanists are guilty of many of the same transgressions against science that Christians have long been accused of, including

  • Attempting to establish a new orthodoxy verging on dogma
  • Stifling of descent
  • Condemning and purging those with non-humanist views
  • Corrupting science for political, social and economic goals

If psychology and the social ‘sciences’ continue to be dominated by a philosophy hostile to the free exploration and exchange of ideas, how will they ever develop desperately needed casual understanding about the human condition? A delay in the behavioral sciences similar to the delay in the physical sciences that occurred between Aristarchus and Copernicus would be more than a scientific tragedy; it would be a disaster for humankind. Our hope has to be that the study of human behavior will somehow break through the confining walls of humanism, undergo a cathartic paradigm shift, and become true science.

Rethinking the origin of cosmic rays

New results from an Italian space-based experiment have astronomers puzzled about the origins of cosmic rays. Cosmic rays are charged particles — protons and other atomic nuclei — that are accelerated to near-light speeds and continue on through the universe. The Earth is awash in them, with dozens of cosmic rays passing through your body every second of every day. Until now, the prevailing explanation for their origin was that they are accelerated by the remnants of supernovae, the spectacular final moments of dying high-mass stars. However, evidence gathered by the exquisitely sensitive Italian space-based instrument, called PAMELA, suggests this is not the case. It seems that different types of particles are accelerated in different ways, contrary to what is expected if they are accelerated by the same source.

It’s another entry in the “We didn’t expect that” file, which is part of what science is all about. And theorists always like the extra business.

Buckyballs in space

Sounds like the title of a cheesy sci-fi movie, doesn’t it? Buckyballs (short for “buckminsterfullerenes”) are the largest molecules that we know of, and just last year they were discovered for the first time in space. Based on their properties, astronomers predicted that buckyballs would exist in certain environments in space and not in others. However, a group using the Spitzer Space Telescope has found precisely the opposite. This is why observation and experiment are so important in science.

Science faction

The Scientific Curmudgeon ponders whether theoretical physics is going soft:

Roger Penrose and V. G. Gurzadyan recently proposed that minute ripples in the cosmic microwave background- the afterglow of the big bang- originated from the collision of monster black holes in another universe that preceded our cosmos, and may have spawned it; moreover, our universe might be just one of an infinite series spawned by such cataclysms.

My reaction to reading about this idea was: Far out! Penrose, one of the most famous, creative physicists in the world, along with Gurzadyan had dusted off the old oscillating universe theory of the cosmos, which I always liked. But not for a nanosecond did I think their proposal was true. The proposal is literally too far out; it can never be confirmed in the way that the existence of quarks has been confirmed or the big bang itself.

This is the problem I’ve always had with the various proposed “theories” of the multiverse: if a proposal can’t be confirmed, it’s not science.

Physics is at a real crossroads with the multiverse. If the majority of physicists accept it as science, the field of physics is doomed; if the majority relegate it to speculation, physics will continue on the path of genuine science.

Stay tuned for a mega-post on the multiverse in the coming months.

Separating philosophy from science

** Written by “Surak” **

An article appeared several months ago in the Daily Telegraph with the headline, “Neuroscience, free will and determinism: ‘I’m just a machine.’” It describes how a British neuroscientist, Professor Patrick Haggard, found that magnetic fields can be used to affect a person’s brain and exert some small degree of control of his body without touching it in any way. The magnetic field is created by a device held close to a person’s head; a technique he calls “transcranial magnetic stimulation.” Although the amount of ‘control’ he was able to demonstrate was only the waggling of his index finger and the twitching of a hand, it was a wonderfully original experiment that sparks the imagination with intriguing visions of further research and possible cures.

Unfortunately the article wasn’t about the scientific possibilities. The researcher chose instead to make wildly speculative philosophical statements in the guise of science:
