Is the taxpayer-funded scientific bureaucracy self-correcting?

4 Comments

Consider this post from Evolution News which talks about a paper in the prestigious pro-naturalism journal Science that is drawing a lot of criticisms. (H/T Melissa, Jonathan)

Excerpt:

Last December we reported on a controversial paper published in Science which claimed to have discovered bacteria that feed on arsenic instead of phosphorous. According to NASA, this research promised to provide “an astrobiology finding that will impact the search for evidence of extraterrestrial life.” At that time the media reported things like:

  • scientists discovered “a bacteria whose DNA is completely alien to what we know today” (Wired)
  • the “bacteria is made of arsenic” (Wired)
  • the bacteria is “capable of using arsenic to build its DNA, RNA, proteins, and cell membranes” (Gizmodo)
  • the paper had reported “arsenic-based life” which is “very alien in terms of how it’s put together” and “NASA has, in a very real sense, discovered a form of alien life” (io9)
  • “you can potentially cross phosphorus off the list of elements required for life” (Nature)

But soon after the original Science paper was published, credible scientists began critiquing the paper’s claims. In the June 3, 2011 issue of Science, several of those scientists have published comments critiquing the original paper. Many of their criticisms focus on the claim that the original paper did not establish or rule out the possibility that the bacteria are not still living off of phosphorous.

So you have a paper being published that everyone is excited about because it helps the naturalists to close gaps in their worldview. But was it good science? The Evolution News piece goes on to list the criticisms of the paper.

And here is the result:

Of course the authors of the original paper, including lead-author Felisa Wolf-Simon, co-authored a reply to the criticisms which should also be read. But critics remain unconvinced. Nature news recently quoted Barry Rosen of Florida International University stating, “I have not found anybody outside of [Wolfe-Simon’s] laboratory who supports the work.” Likewise, Rosie Redfield observes:

“With so many mistakes pointed out, there should be at least some where the authors say, ‘you’re right, we should have done that but we didn’t’,” Redfield says. “This as an entirely a ‘we were right’ response, and that’s a bad sign in science.”

Despite the high levels of skepticism of claims of arsenophilic bacteria, Nature reports that few scientists have taken the initiative to attempt to experimentally reproduce the claims made in the original paper:

However, most labs seem too busy to spend time replicating work that they feel is fundamentally flawed and is not likely to be published in high-impact journals. So principal investigators are reluctant to spend their resources, and their students’ time, replicating the work. “If you extended the results to show there is no detectable arsenic, where could you publish that?” asks Simon Silver of the University of Illinois at Chicago, who critiqued the work in FEMS Microbiology Letters in January and on 24 May at the annual meeting of the American Society for Microbiology in New Orleans. “How could the young person who was asked to do that work ever get a job?” Refuting another scientist’s work also takes time that scientists could be spending on their own research. For instance, Helmann says he is installing a highly sensitive mass spectrometer that can measure trace amounts of elements. But, he says, “I’ve got my own science to do.”

Such admissions do not bode well for those who blindly believe in the perfectly objective, self-correcting nature of science. In this case, it seems safe to experimentally critique these claims since so many respected scientists have already expressed vocal skepticism. Yet experiments are apparently not yet forthcoming. What about areas of science where scientists are not able to express their dissent freely? For example, who would take time to experimentally critique claims that are central to neo-Darwinian theory, especially if it’s dangerous to one’s career? One hopes that science will become more self-correcting when it comes to claims made in support of materialism.

In light of what we now know about global warming research, shouldn’t we be a little more welcoming of whistleblowers and critics? Shouldn’t we be a little more careful about hastily approving research that agrees with the religion of naturalism, instead of checking it over thoroughly to make sure that it really is good science?

Christian scholar Jay Richards was interviewed by Brian Auten of Apologetics 315.

The MP3 file is here.

Topics:

  • What is intelligent design (ID)?
  • Is ID specifically Christian?
  • How does ID helpful to Christian apologetics?
  • What does ID prove?
  • Is it OK to use an argument that doesn’t prove Christianity specifically?
  • What is the difference between deism and theism?
  • Do ID arguments get you to deism or theism?
  • What is materialism, and how can you challenge it?
  • How do opponents of ID define ID?
  • What factors do you need to make a habitable planet?
  • Are habitable planets common or rare in the universe?
  • What is “The Privileged Planet” hypothesis?
  • Is there an overlap between habitability and suitability for making scientific discoveries?
  • What is the “Copernican Principle”?
  • Has the progress of science made Earth seem common and ordinary?
  • What is the most Earth-like planet that we’ve ever discovered?
  • How should ID proponents respond to the objection that creatures aren’t perfect?
  • Does having a big moon make a planet more or less habitable?
  • Does a planet’s distance to the Sun make that planet more or less habitable?
  • How do these two habitability factors affect the observability of solar eclipses?
  • What does co-relation between habitability and “discoverability” tell us about God?
  • How important is training in philosophy to Christian apologetics?
  • What one thing should a Christian apologist work on to be more effective?

I’m hoping that Brian will do a follow-up interview with Jay on Jay’s new book on theistic evolution.

Here’s the description from Amazon.com:

What does it mean to say that God “used evolution” to create the world? Is Darwin’s theory of evolution compatible with belief in God? And even if Darwin’s theory could be reconciled with religious belief, do we need to do so? Is the theory well established scientifically? Is it true?

In the century and a half since Charles Darwin first proposed his theory of evolution, Christians, Jews, and other religious believers have grappled with how to make sense of it. Most have understood that Darwin’s theory has profound theological implications, but their responses have varied dramatically.

Some religious believers have rejected it outright; others, often called “theistic evolutionists,” have sought to reconcile Darwin’s theory with their religious beliefs, but often at the cost of clarity, orthodoxy, or both. Too few have carefully teased out the various scientific, philosophical, and theological claims at stake, and separated the chaff from the wheat. As a result, the whole subject of God and evolution has been an enigma wrapped in a shroud of fuzz and surrounded by blanket of fog.

The purpose of this anthology of essays is to clear away the fog, the fuzz, and the enigma. Contributing authors to the volume include Jay Richards, co-author of The Privileged Planet: How Our Place in the Cosmos Is Designed for Discovery; Stephen Meyer, author of Signature in the Cell: DNA and the Evidence for Intelligent Design; William Dembski, author of The Design Revolution; Jonathan Witt, co-author of A Meaningful World: How the Arts and Sciences Reveal the Genius of Nature; Denyse O’Leary, author of By Design, or by Chance?; and David Klinghoffer, author of Shattered Tablets.

Those authors are some of my favorite people to read in the whole world. I think this group will be mostly fed up with theistic evolutionists, like I am, although they may not go as far as I do when I label theistic evolutionists “functional atheists” or “theistic atheists”.

Jay Richards is probably my favorite all-round Christian scholar, because he also writes a lot on policy and economics, and was interviewed on those topics by Frank Turek. He has a complete, well-rounded worldview.

Harvard astrophysicist backs the Rare Earth hypothesis

2 Comments

What is the Rare Earth hypothesis?

It’s the thesis of a recent book written by two scientists at the University of Washington.

Here’s the blurb:

What determines whether complex life will arise on a planet? How frequent is life in the Universe?

In this exciting new book, distinguished paleontologist Peter D. Ward and noted astronomer Donald Brownlee team up to give us a fascinating synthesis of what’s now known about the rise of life on Earth and how it sheds light on possibilities for organic life forms elsewhere in the Universe.

Life, Ward and Brownlee assert, is paradoxically both very common and almost nowhere. The conditions that foster the beginnings of life in our galaxy are plentiful. But contrary to the usual assumption that if alien life exists, it’s bound to be intelligent, the authors contend that the kind of complex life we find on Earth is unlikely to exist anywhere else; indeed it is probably unique to our planet.

With broad expertise and wonderful descriptive imagery, the authors give us a compelling argument, a splendid introduction to the emerging field of astrobiology, and a lively discussion of the remarkable findings that are being generated by new research. We learn not only about the extraordinary creatures living in conditions once though inimical to life and the latest evidence of early life on Earth, but also about the discoveries of extrasolar planets, the parts Jupiter and the Moon have played in our survival, and even the crucial role of continental drift in our existence.

Insightful, well-written, and at the cutting edge of modern scientific investigation, Rare Earth should interest anyone who wants to know about life elsewhere and gain a fresh perspective on life at home which, if the authors are right, is even more precious than we may ever have imagined.

And here’s a review by Library Journal:

“Renowned paleontologist Ward (Univ. of Washington), who has authored numerous books and articles, and Brownlee, a noted astronomer who has also researched extraterrestrial materials, combine their interests, research, and collaborative thoughts to present a startling new hypothesis: bacterial life forms may be in many galaxies, but complex life forms, like those that have evolved on Earth, are rare in the universe. Ward and Brownlee attribute Earth’s evolutionary achievements to the following critical factors: our optimal distance from the sun, the positive effects of the moon’s gravity on our climate, plate tectonics and continental drift, the right types of metals and elements, ample liquid water, maintainance of the correct amount of internal heat to keep surface temperatures within a habitable range, and a gaseous planet the size of Jupiter to shield Earth from catastrophic meteoric bombardment. Arguing that complex life is a rare event in the universe, this compelling book magnifies the significance — and tragedy — of species extinction. Highly recommended for all public and academic libraries.”

Note that Peter Ward is a militant atheist (he has debated against Stephen C. Meyer), and Donald Brownlee is an agnostic. These are not Christians, nor are they even theists. However, I have the book, I have read the book, and I recommend the book. I usually have this book on my shelf at work for show-and-tell.

Now for the latest news about the hypothesis of the book. (H/T Brian Auten of Apologetics 315)

There are always going to be optimistic predictions by scientists who need to attract research funding, but those are hopes and speculations. The data we have today says Earth is rare. The number of conditions required for complex life of any kind is too high for us to be optimistic about alien life in this galaxy, at least. And as the number of requirements for life roll in, the odds of finding alien life that can contact us get slimmer and slimmer.

From the UK Daily Mail. (H/T Peter S. Williams)

Excerpt:

Dr Howard Smith, a senior astrophysicist at Harvard University, believes there is very little hope of discovering aliens and, even if we did, it would be almost impossible to make contact.

So far astronomers have discovered a total of 500 planets in distant solar systems – known as extrasolar systems – although they believe billions of others exist.

But Dr Smith points out that many of these planets are either too close to their sun or too far away, meaning their surface temperatures are so extreme they could not support life.

Others have unusual orbits which cause vast temperature variations making it impossible for water to exist as a liquid – an essential element for life.

Dr Smith said: ‘We have found that most other planets and solar systems are wildly different from our own.

‘They are very hostile to life as we know it.’

‘The new information we are getting suggests we could effectively be alone in the universe.

‘There are very few solar systems or planets like ours. It means it is highly unlikely there are any planets with intelligent life close enough for us to make contact.’ But his controversial suggestions contradict other leading scientists – who have claimed aliens almost certainly exist.

These arguments are actually quite useful, and I include them in my standard list of scientific arguments for theism. (See below) You have to know this stuff cold. Most people believe in aliens because they watched movies made by artists. As a result, they think that humans are nothing special and that God is not interested in us in particular. Which is very convenient for them, because it means they can do whatever they want and not care what God thinks about what they are doing. If you want to defend against the idea that humans are nothing special, and that we were not placed here for a purpose, and that we are not accountable and obligated to seek and know the Creator/Designer, then you’ll need more than feelings. You’ll need science. You’ll need the best science available.
