Researchers have found that manganese, an abundant and inexpensive metal, can be used to efficiently convert carbon dioxide into formate, a potential hydrogen source for fuel cells. The key was a clever redesign that made the catalyst last far longer than similar low-cost materials. Surprisingly, the improved manganese catalyst even beat many expensive precious-metal options. The discovery could help turn greenhouse gas into clean energy ingredients.

Astronomers have produced the most detailed map yet of dark matter, revealing the invisible framework that shaped the Universe long before stars and galaxies formed. Using powerful new observations from NASA’s James Webb Space Telescope, the research shows how dark matter gathered ordinary matter into dense regions, setting the stage for galaxies like the Milky Way and eventually planets like Earth.

SpaceX CEO Elon Musk says he’s making space-based artificial intelligence the “immediate focus” of a newly expanded company that not only builds rockets and satellites, but also controls xAI’s generative-AI software and the X social-media platform. That’s the upshot of Musk's announcement that SpaceX has acquired xAI.

Arp 220 is a well-known pair of galaxies that are merging. New ALMA observations of polarized light reveal the complex and powerful magnetic fields that shape the process.

This NASA/ESA Hubble Space Telescope image shows NGC 7722, a lenticular galaxy about 187 million light-years away in the constellation Pegasus. This “lens-shaped” galaxy sits in between more familiar spiral alaxies and elliptical galaxies in the galaxy classification scheme. The dark, dramatic dust lanes are the fingerprints of an ancient galaxy merger.

For the first time, researchers have found what seems to be a cloud of dark matter about 60 million times the mass of the sun in our galactic neighbourhood

Yes, the author of the new Quillette article, a critique of sociologist Charles Murray‘s “proof” of Christianity, really is an atheist, though he says he’s not a proselytizing one. Daseler is identified as “a film editor and writer living in LA. And Daseler says in the article below that’s he’s not an ardent atheist, though he’d like to believe in God. But he sure thinks like an atheist as he takes apart Murray’s “scientific” arguments for God.

Like Ross Douthat, Murray has a new book about why we should be religious; Murray’s is called Taking Religion Seriously.  And many of Murray’s arguments for God, which we’ve encountered before, overlap with Douthat’s: they are arguments for God from ignorance, posting not just God but a Christian god—based on things we don’t understand.  Here’s what I said in an earlier piece on this site:

Here’s a quote from the publisher’s page:

Taking Religion Seriously is Murray’s autobiographical account of the decades-long evolution in his stance toward the idea of God in general and Christianity in particular.

Murray, then, has a harder task than just convincing us that there’s a supreme being: he has to convince us that it’s the supreme being touted by Christianity. To do that he must, as Daseler shows, support the literal truth of the New Testament, and even Bart Ehrman doesn’t do that.

But I digress; click below to read Daseler’s review, which is also archived here.

I’ll summarize Murray’s arguments for God in bold; indented headings are mine while Daseler’s test itself is indented and my own comments flush left.

a.) There is something rather than nothing.

b.) Physics is often mathematically simple, like equations for motion and gravitation. 

I’ve discussed these two before, and also provided links to others who find them unconvincing arguments for God. (Why do I keep capitalizing “God” as if he exists? I don’t know.)

c.) Some people show “terminal lucidity” (“TL”). That is, some people in a vegetative state, or with profound dementia, suddenly become very lucid before they die. 

In another post I pointed out Steve Pinker and Michael Shermer’s arguments against taking TL as evidence for God  Daseler adds further evidence:

Terminal lucidity is no better at propping up Murray’s case for an immortal soul, as he tacitly admitted during a recent back-and-forth with the cognitive psychologist Steven Pinker. To date, only one very small study has been conducted on terminal lucidity, indicating that it occurs in approximately six percent of dementia patients. No EEGs, brain imaging, or blood samples were taken during these episodes, so any explanations of the phenomenon must be speculative. The neuroscientist Ariel Zeleznikow-Johnston has hypothesised that terminal lucidity may result, at least in some instances, from a reduction in brain swelling. “In their final days, many patients stop eating and drinking entirely,” he explains. “The resulting dehydration could reduce brain swelling, allowing blood flow to increase and temporarily restoring some cognitive function—a brief window of lucidity before the dying process continues.” Nonetheless, Zeleznikow-Johnston is quick to acknowledge that this is merely an educated guess. Murray, by contrast, jumps straight to the conclusion that corroborates his priors: episodes of terminal lucidity reveal the fingerprints of the soul.

I should add that Murray also accepts “near-death experiences” (“NDE”s) as evidence for God, as do recent books like Heaven is for Real and Proof of Heaven: A Neurosurgeon’s Journey into the Afterlife. Both of these books have been thoroughly debunked elsewhere, and some Googling will turn up ample critiques.

d.) The universe is “fine-tuned” for life. That is, it is more than a coincidence that the physical parameters obtaining in the Universe allow life on at least one planet. Ergo, say people like Murray

This argument seems to convince many people, but not physicists. Indeed, even Daseler finds it hard to refute. But there are many alternative explanations save Murray’s view that the parameters of physics were chosen by God to allow his favorite species to evolve. There could be multiple universes with different physical parameters; most of the Universe is not conducive to life; or there could be a reason we don’t understand why the physical parameters are what they are, and are somehow interlinked. The best answer is “we don’t know,” but Murray thinks that one alternative—the Christian God—is the most parsimonious answer.  But of course he wants to believe in God, and since we have no other evidence for a supreme being, it’s not so parsimonious after all.

e.) There is evidence that the Gospels are factually true.

Anyone who’s studied religious history with an open mind knows this is bogus, for the canonical gospels were written well after Jesus’s death, and by people who had never met the purported Savior.  Murray does some mental gymnastics to obviate this, but he isn’t successful. And, as Daseler points out, the New Testament is full of mistakes (so is the Old Testament: there was, for example, no exodus of the Jews from Egypt).  Here’s a handy list provided by Daseler:

• There was no census during the reign of Caesar Augustus for which citizens had to return to their ancestral homes, as the Gospel of Luke maintains.
• Cyrenius was not the governor of Syria at the time of Jesus’s birth.
• There’s no record, outside the Gospel of Matthew, of Herod the Great slaughtering hundreds of newborn babies.
• When Jesus quotes the Old Testament in the Sermon on the Mount, he quotes from the Septuagint, which was written in Greek, a language neither he nor his listeners spoke.
• The Romans didn’t allow the Jewish Council to meet at night.
• By law, capital trials of the kind Jesus underwent had to be conducted over two days, and never on a Sabbath or holy day.
• There was no tradition of releasing a prisoner to the Jewish people before Passover. The notion that Pontius Pilate, a notoriously ruthless governor, would have released Barabbas, a murderous insurrectionist, is highly unlikely.
• Crucified criminals were commonly left on their crosses for days, as a warning to would-be malefactors, then dumped in mass graves, not promptly taken down and buried in rich men’s tombs.

And this is to say nothing of the supernatural events described in the gospels, such as Matthew’s report that, after the crucifixion, “the graves were opened; and many bodies of the saints which slept arose, And came out of the graves after his resurrection, and went into the holy city, and appeared unto many,” an incident that, had it actually occurred, would certainly have been recorded by additional sources. Likewise, there are scenes that, logically, must have been invented. If Jesus and Pilate had a private conversation together just before Jesus died, how does the author of the Gospel of John know what they said? And if Matthew and Luke actually witnessed the events they describe, why did they feel the need to plagiarise so many passages word-for-word from Mark?

Still, Murray thinks that the gospels are statements of witnesses, which simply cannot be true based on both historical and internal evidence.

Murray also has a weakness for nonreligious woo, which speaks to his credulity. Daseler:

Like Douthat, Murray has a capacious definition of the word religion that encompasses a fair amount of woo as well as Christian orthodoxy. “I put forward, as a working hypothesis, that ESP is real but belongs to a mental universe that is too fluid and evanescent to fit within the rigid protocols of controlled scientific testing,” he writes, discarding his commitment to fact-based assertions. Murray devotes an entire chapter to discussing near-death experiences—or NDEs, as they’re popularly known—and terminal lucidity, the rare but documented phenomenon of brain-damaged patients regaining some cognitive abilities just before they die. “In my judgment [NDEs and terminal lucidity] add up to proof that the materialist explanation of consciousness is incomplete,” he writes. “I had to acknowledge the possibility that I have a soul.”

The only credit Daseler gives Murray is that the sociologist isn’t “preachy”, and hedges his assertions with words like “I think.”

In the end, Murray offers the same tired old arguments advanced against God during the last few decades: all arguments based on ignorance, ignorance equated to a Christian God. And although Daseler says he wants to believe, he simply can’t because, unlike Murray (who claims to proffer evidence in the book The Bell Curve for group difference in intelligence), Daseler is wedded to evidence. And so the reviewer fights his own wishes in favor of evidence—or the lack thereof:

I’m not nearly as ardent an atheist as this review might lead some to think. I wasn’t raised with any religion, so I don’t have a childhood grudge against any particular creed. And unlike Christopher Hitchens, who liked to say that he was glad that God does not exist, I can’t say I’m overjoyed to think that the universe is cold and conscienceless. I’d be delighted to discover that there is a supreme being, so long as He/She/It is compassionate and merciful. I am, in short, exactly the type of person Murray is trying to reach—someone much like himself before he started reading Christian apologetics. Every time I open a book like his, some part of me yearns to be persuaded, and to be given an argument or a piece of evidence that I’ve yet to consider. But Murray fails to deliver. After reading his book, I’m less, not more, inclined to take religion seriously. It’s hard to believe in God when even very bright, thoughtful people can’t come up with good reasons why you should.

I guess I’m like Hitchens here: why wish for something that doesn’t exist? Why not face up to reality and make the best of it?  Apparently Murray doesn’t share those sentiments.

If you want a decent but flawed explanation of “God of the gaps” arguments, click on the screenshot below. You can have fun mentally arguing with the author’s claim that some “gaps” arguments from theism are better than related arguments from naturalism, though the piece as a whole is anti-supernatural. Personally (and self-aggrandizingly), I think the discussion in Faith Versus Fact is better.  But I like the picture (it’s uncredited), and the author does quote theologian Dietrich Bonhoeffer:

 “. . . how wrong it is to use God as a stop-gap for the incompleteness of our knowledge. If in fact the frontiers of knowledge are being pushed further and further back (and that is bound to be the case), then God is being pushed back with them, and is therefore continually in retreat. We are to find God in what we know, not in what we don’t know.”

But in the 80 years since Bonhoeffer was hanged by the Nazis, we still haven’t found God in what we know.

Over in Punxsutawney, Pennsylvania, they dragged out a groggy groundhog (Marmota monax), Punxsutawney Phil, from his wooden-box den, and determined whether he could see his shadow.

He did, and that means that we have six more weeks of winter weather to come.  Is that any surprise?

Below is a short video in which Phil is forced to look at a piece of paper. Who knows if he actually saw his shadown, but the top-hatted flacks, members of the so-called “Inner Circle” who interpret Phil’s predictions, did.

But looking at Phil’s history, the rodent is not accurate at predicting the long-term weather:

The Inner Circle claims a 100% accuracy rate, and an approximately 80% accuracy rate in recorded predictions. If a prediction is wrong, they claim that the person in charge of translating the message must have made a mistake in their interpretation. Empirical estimates place the groundhog’s accuracy between 35% and 41%.

So it goes.  It’s a groundhog, for crying out loud, not a weatherman. And the Inner Circle is a religion. . . .

 

MACE is a next-generation experiment designed to catch muonium transforming into its antimatter twin, a process that would rewrite the rules of particle physics. The last search for this effect ended more than two decades ago, and MACE plans to leap far beyond it using cutting-edge beams, targets, and detectors. A discovery would point to entirely new forces or particles operating at extreme energy scales.

NASA’s SpaceX Crew-12 team has entered a carefully controlled two-week quarantine as the countdown begins for their journey to the International Space Station. The four astronauts—representing NASA, the European Space Agency, and Roscosmos—are isolating at Johnson Space Center before heading to Florida for final launch preparations. The mission could lift off as early as February 11, with multiple backup launch windows lined up.
