Dodging the rocks

Category: science,space,theologyharmonicminer @ 9:26 am

The observation has been made recently that Life in the inner galaxy would be bombarded by comets

WE’RE lucky Earth resides in the Milky Way’s suburbs. Intense comet bombardment near the galaxy’s centre may make it tough for life to gain a foothold there.

Earth and the other planets of our solar system suffer occasional impacts when comets are disturbed from their orbits around the sun by the gravity of nearby stars and gas clouds.

The effect is stronger closer to the galaxy’s centre, where stars and gas clouds are more tightly packed. More than twice as many comets are shaken loose to potentially hit planets at half our distance to the centre, according to simulations by Marco Masi of the University of Padua, Italy, and his colleagues

People who study such things are telling us that the Earth is at the just-right distance from the galactic center, at the just-right distance from the Sun, with a just-right moon that creates tides, more critical for life than was once understood. The moon also helps keep the Earth at its just-right axial tilt so that we have seasons, which are sometimes annoying, but also critical for advanced life.

These facts are just the tip of the iceberg about the exceedingly rare “just-rightness” of our world for advanced life, and also the “just-rightness” of our world for intelligent life (that would be us) to be able to learn about the universe by observation.

Some people think this is a huge accident.

I don’t.

Climategate? Or just business as usual?

Category: environment,global warming,scienceharmonicminer @ 10:20 am

The lies of the global warming eco-panic crowd may finally be exposed in Climategate: the final nail in the coffin of ‘Anthropogenic Global Warming’?

If you own any shares in alternative energy companies I should start dumping them NOW. The conspiracy behind the Anthropogenic Global Warming myth (aka AGW; aka ManBearPig) has been suddenly, brutally and quite deliciously exposed after a hacker broke into the computers at the University of East Anglia’s Climate Research Unit (aka Hadley CRU) and released 61 megabites of confidential files onto the internet. (Hat tip: Watts Up With That)

When you read some of those files, including 1079 emails and 72 documents, you realise just why the boffins at Hadley CRU might have preferred to keep them confidential. As Andrew Bolt puts it, this scandal could well be “the greatest in modern science”. These alleged emails, supposedly exchanged by some of the most prominent scientists pushing AGW theory, suggest:

Conspiracy, collusion in exaggerating warming data, possibly illegal destruction of embarrassing information, organised resistance to disclosure, manipulation of data, private admissions of flaws in their public claims and much more.

One of the alleged emails has a gentle gloat over the death in 2004 of John L Daly (one of the first climate change sceptics, founder of the Still Waiting For Greenhouse site), commenting:

“In an odd way this is cheering news.”

But perhaps the most damaging revelations , the scientific equivalent of the Telegraph’s MPs’ expenses scandal, are those concerning the way Warmist scientists may variously have manipulated or suppressed evidence in order to support their cause.

It is, of course, early days in the investigation of the stolen emails.  Perhaps it will all turn out to be a huge hoax.  But, here are more details.

Of course, the AGW eco-panic mongers of the world will say that this isn’t the only data, that many other independent data sources have confirmed the same conclusions, and it can’t ALL be a hoax.

Maybe not.  Some of it could be just simple, politically motivated non-science.  There are probably some well-meaning sorts who have particular data that doesn’t, by itself, refute AGW, so they have trusted those who are sure they have data that confirms it.  But it seems that maybe there aren’t as many scientists as previously claimed who are “sure” they have confirming data…  so they cook the books.

Here is an attempt at damage control.  You can decide how successful you think it is.  My impression: while accusing the hackers of “cherry picking”, they have “cherry picked” the emails the hackers “cherry picked” to try to make their points.  Your mileage may vary.  But I wonder how many of these bleats about the nasty, illegal, immoral hackers were issued by people who were similarly distressed when the New York Times exposed critical US programs to protect us from terrorists.  (You may say this is a loose connection, but the political dimension of the AGW controversy is the entire point….  and the politics of eco-panic mongers and anti-American Leftists are remarkably parallel.)  Here is someone who takes it more seriously.

This seems like a good time to review all those scientists who have thought all along that AGW was, if true, a very minor contributor to whatever overall warming may exist (which it seems is less and less).

The Next Great Awakening Part 12: Nothing is complete without God

Category: philosophy,religion,scienceharmonicminer @ 9:47 am

The previous post in this series is here.

Perry Marshall has put up a brief introduction to the mathematical thought of Kurt Gödel.  After a brief explanation of it, he draws connections to the idea of the mathematical necessity for a Creator in Gödel’s Incompleteness: The #1 Mathematical Breakthrough of the 20th Century

If you visit the world’s largest atheist website, Infidels, on the home page you will find the following statement:

“Naturalism is the hypothesis that the natural world is a closed system, which means that nothing that is not part of the natural world affects it.”

If you know Gödel’s theorem, you know all systems rely on something outside the system. So according to Gödel’s Incompleteness theorem, the folks at Infidels cannot be correct.  Because the universe is a system, it has to have an outside cause.

Therefore Atheism violates the laws of mathematics.

The Incompleteness of the universe isn’t proof that God exists. But it IS proof that in order to construct a consistent model of the universe, belief in God is not just 100% logical, it’s necessary.

Euclid’s 5 postulates aren’t formally provable and God is not formally provable either. But just as you cannot build a coherent system of geometry without Euclid’s 5 postulates, neither can you build a coherent description of the universe without a First Cause and a Source of order.

Thus faith and science are not enemies, but allies. They are two sides of the same coin. It had been true for hundreds of years, but in 1931 this skinny young Austrian mathematician named Kurt Gödel proved it.

No time in the history of mankind has faith in God been more reasonable, more logical, or more thoroughly supported by rational thought, science and mathematics.

Everyone understands the Incompleteness Theorem in a personal way, and knows that it applies to the most important issues of life.

Only the most trivial, least important aspects of life involve things that can be proved in the way the objectivists wanted to do it. You can’t “prove” that you love your child, that there is any point to existence, that you are loved by the person whom you hope loves you, that you don’t plan to do some great evil tomorrow (or, for that matter, that you didn’t yesterday, the “negative” being notoriously difficult to prove), etc.

Yet we all live as if our lives matter, as if at least some other people’s lives matter, as if love is real, as if we are certain that their is some underlying rationality to the universe that is not containable within it, etc.    Scientists live and work in that latter assumption whenever they assume that the “laws” of physics are the same everywhere and everywhen, which is an unprovable notion, but foundational for the ability to DO science.  And the very idea that the universe may be understandable requires an assumption about its nature and, probably, its origin, that cannot be “proved.”

In other words, in the business of being a human being and living a normal life, very little of high and immediate importance can be proved.  Yet we all, with very little exception, live as if some of our foundational assumptions are true.  Love exists.  Rationality exists.  People matter.  It matters how we live.

These things are, while not “provable,” nevertheless as true as Euclid’s postulates, demonstrable by the simple observation that without them, nothing makes any sense at all.

The First Postulate, of course, is that God IS.  And it is surely true that, without God, nothing makes any sense, any sense at all.   Not love, not rationality, not human life, not the universe, not anything.

The Second Postulate:  everything that exists makes the most sense when understood in its relationship to our Creator.

Some will argue that only the First Postulate deserves the label “postulate,” but I think the Second Postulate protects us from Deism.

God is involved with us, and with everything that is, right now.

The Third Postulate is that God has revealed Himself to us, in Christ, in human lives and traditions, in words and history, and in nature.

I think these postulates are all one needs to seek God, who is surely seeking us, and does not require us to “prove” that He is there before being in relationship with Him.

What’s really interesting is that Gödel appears to have tried to “prove” the existence of God….  perhaps a sign of lack of faith in the implications of his own work, though his faith in God seems to have been strong.

Earth and Jupiter in same photo

Category: science,spaceharmonicminer @ 9:26 am

Stunning photo: Earth and Jupiter in the same shot

Sometimes the planets line up in such a way that you can see Earth and Jupiter in the same wide-angle shot. That is, if you were aboard the Mars Global Surveyor on May 22, 2003. When the Mars Orbiter Camera snapped this unique view, Earth was 86 million miles away, and Jupiter was 600 million miles away.

How on earth is it even possible to take such a shot? Continue reading to see a larger version of this magnificent photo, and then you can see a diagram of how the planets were lined up to enable such a thing.

The comet that didn’t splash down in the primordial soup that wasn’t there

Category: scienceharmonicminer @ 9:49 am

I’ve mentioned in “Then Next Great Awakening” series on this blog (tab at the top) that life scientists are so far from figuring out a way to explain the origin of life on earth that they are looking to E.T. as an explanation. Now there’s a new book out called Comets and the Origin of Life by Janaki Wickramasinghe, Chandra Wickramasinghe and William Napier.   A reviewer said:

STEP by step, the case for an extraterrestrial origin of life has got stronger.

TRANSLATION: THE CASE FOR THE SPONTANEOUS ORIGIN OF LIFE ON EARTH IS SO WEAK AS TO BE LAUGHABLE… AND THE BIG BRAINS CAN’T THINK OF ANYTHING BETTER THAN COMETS BRINGING IT TO EARTH, IN SOME KIND OF “DNA EX MACHINA.”

But though the case for planetary panspermia – the idea that micro-organisms transfer between planets – is now widely accepted, interstellar panspermia remains controversial.

WELL, OF COURSE.   EVERYONE RAISE YOUR HAND WHO THINKS THAT CELLS SURVIVED FOR TENS OR HUNDREDS OF THOUSANDS OF YEARS (MAYBE MILLIONS?) THROUGH INTERSTELLAR SPACE, VACUUM, COSMIC RAYS, AND WHO KNOWS WHAT.  If you think enough survived to seed life on earth in sufficient volume to survive incredibly hostile early earth conditions, completely unlike the comet, raise TWO hands.  Then smack yourself in the head with one of them.

A key element in the scheme, promoted by Chandra Wickramasinghe and the late Fred Hoyle, are comets, the bodies in which the desiccated bacteria of interstellar space are claimed to come to life before being ferried to planetary surfaces. The recent discovery of amino acids and clays in comets, which could have formed only if comets once had liquid-water interiors, bolsters the case for interstellar panspermia.

SURE IT DOES. ABOUT LIKE THE DISCOVERY THAT MARS HAD VISIBLE LINES BOLSTERED THE CASE FOR MARTIAN “CANALS”.

Yet most scientists require more evidence.

HAPPY TO HEAR IT.

I think this entire discussion is best characterized as “materialism of the gaps.”

The Next Great Awakening, Part 10: Your brain is not a computer, and your mind is not your brain

Category: philosophy,religion,scienceharmonicminer @ 9:48 am

The previous post in this series is here.

In a very interesting interview on the unlikelihood that Sci-Fi style artificial intelligence (AI) is coming soon, or even possible, computer scientist Noel Sharkey says why he thinks that AI is a dangerous dream –

I’m an empirical kind of guy, and there is just no evidence of an artificial toehold in sentience. It is often forgotten that the idea of mind or brain as computational is merely an assumption, not a truth. When I point this out to “believers” in the computational theory of mind, some of their arguments are almost religious. They say, “What else could there be? Do you think mind is supernatural?” But accepting mind as a physical entity does not tell us what kind of physical entity it is. It could be a physical system that cannot be recreated by a computer.

Of course, materialists have a very hard time accepting that anything of non-material nature exists, anything that is not some mere arrangement of matter and energy, space and time.  What the materialist approach fails to explain is that this theory is itself a non-material thing.  What is the materialist nature of an idea?  Calling it a mere brain state, even a brain state that is shared by others, forces us into the notion that a “brain state” is about something.  Yet the materialists have mostly asserted that what we call consciousness is mere “noise in the system.”  How to account for “brain states” that are about other “brain states” which are attempts to account for the existence of other “brain states”?  One is tempted to take seriously the idea that maybe the minds of materialists are just “noise in the system.”

(Editorial comment in 2023:  For our purposes here, don’t confuse large language models like ChatGPT with actual AI in sense discussed above.  ChatGPT is not sentient, and will “tell” you so. No current AI whose existence is public is “sentient”, which begs the question of what is meant by the word “intelligence” in “artificial intelligence.”  This is probably because no one has any real concept of just what consciousness or sentience is, how it works, what produces it, etc.  Large language models, as neural-net systems that have been trained with enormous amounts of linguistic usage as data, boil down to the management of lists of billions of possible verbal formulations, and the assignment of probabilities to them.  Sentience is something quite a bit more mysterious than a large list with assigned probabilities.)

In his book, The Spiritual Brain, neuroscientist Mario Beauregard adduces the evidence for a non-material mind that is related to but independent of the physical brain.

In the book, Beauregard makes short work of claims of a “God gene” or a “God spot” in the brain, something that would provide a false sense of transcendental experience that could be falsely attributed to God by the gullible.   He asks some very interesting questions about the placebo effect, and what that effect suggests about the relationships of mind, brain and body.  His discussion of the small but persistently measurable PSI effect is very interesting, and refreshing to read from a scientist.   Especially interesting is the discussion about the implications of psycho-therapeutic models that involve teaching people to think different ways, essentially using “mind” to affect “brain,” producing measurable physical effects by changing ideas held by a person.   Beauregard’s work in using functional MRI to study the brains of meditating Carmelite nuns is very interesting, and well worth reading.

You may have the impression that someday science will explain the mind in physical terms.  This is certainly the notion that materialist neuroscientists would like to create in the public mind, yet another form of promissory materialism.

The problem, of course, is that a promise of future theoretical success is a non-material idea flowing from a non-material motivation to defend a non-material perspective about the nature of things.  It seems an impossible task.

Think of it as analogous to trying to write an essay on the topic, “Why there is no such thing as an essay.”  (Coming up next:  “Why there is no such thing as a question….  or an answer.”)

The amazing thing about the human mind is not that it has a non-material aspect.   It is that it has a physical aspect.   After all, the human mind is an echo or image of the non-material Mind behind everything.   Of course it has a non-material aspect.  The amazing thing is that the Creator made a unique integration of mind, brain and body, one that seems to have been designed specifically to allow free moral choice in a physical universe that is of non-physical origin, one characterized as much by quantum uncertainty, which makes free will possible, as by obvious cause and effect relationships.

The ice is falling, the ice is falling!!!!

Category: global warming,scienceharmonicminer @ 9:14 am

Why the Greenland and Antarctic Ice Sheets are Not Collapsing

Global warming alarmists have suggested that the ice sheets of Greenland and Antarctica may collapse, causing disastrous sea level rise. This idea is based on the concept of an ice sheet sliding down an inclined plane on a base lubricated by meltwater, which is itself increasing because of global warming.

In reality the Greenland and Antarctic ice sheets occupy deep basins, and cannot slide down a plane. Furthermore glacial flow depends on stress (including the important yield stress) as well as temperature, and much of the ice sheets are well below melting point.

The accumulation of kilometres of undisturbed ice in cores in Greenland and Antarctica (the same ones that are sometimes used to fuel ideas of global warming) show hundreds of thousands of years of accumulation with no melting or flow. Except around the edges, ice sheets flow at the base, and depend on geothermal heat, not the climate at the surface. It is impossible for the Greenland and Antarctic ice sheets to ‘collapse’.

Much more at the link. But don’t worry… the ice is going to be here for quite some time.

The Next Great Awakening, Part 8: Someone to watch over us?

Category: science,theologyharmonicminer @ 9:24 am

The previous post in this series is here.

IN a book review of Heaven’s Touch by James B. Kaler – the reviewer reports this point made in the book:

The real surprise of the past few decades must be the vulnerability of the Earth to truly cosmic events – not only supernovae, whose “killing zones” may extend within 30 light years of us, but also gamma ray bursters whose emissions, beamed like death rays, could scour life from planets 6000 light years away. I have a soft spot for magnetars, ultra-dense neutron stars with the strongest magnetic fields in the universe, and Kaler covers these in detail. In 1998, the eruption of one such star 20,000 light years away generated X-rays so powerful that anyone in Earth orbit would have had the equivalent of a dental X-ray. Six years later, the Earth was irradiated by a magnetar outburst 100 times more powerful.

The reviewer is referring to the fact that cosmologists and astrophysicists have begun wondering, of late, just why we’re still here.  They are beginning to understand that the universe is indeed a very dangerous place, and it seems less and less likely that life can begin on a planet and continue to grow and develop for nearly 4 billion years without simply being destroyed by stellar events in nearby star systems…  “nearby” meaning 6,000 light years or so.  Call it 36,000,000,000,000,000 miles or so.  Within that range certain kinds of supernovae, gamma ray bursts, and more exotic things have the capacity to threaten whatever life may exist.

Even a standard, every day supernova may be dangerous within a hundred light years or so, depending on the size of the supernova.  There may be three to five supernovae per century in Milky Way size galaxies.  Estimates vary, but that’s a typical current guess.  Modern astronomy hasn’t existed long enough to develop a baseline through direct observation of any single galaxy, but by observing 100 comparable galaxies for 10 years, astronomers can develop estimates that might be equivalent to watching one galaxy for 1000 years.  So if in that period, observers see 30 supernovae, they can guess that 3 per century might be a reasonable estimate.  But it’s early times yet.  We’ll know a lot more in the coming decades.

A few minutes with a calculator will suggest that there have been maybe 100 million supernovae in the Milky Way galaxy since there was life on Earth.  The galaxy is “only” about 100,000 light years in diameter.  Supernovae will certainly be more common where stars are more densely packed.  Even so, is it so unlikely that one of those supernovae could easily have exploded near enough to Earth to kill its lifeforms?  Maybe more than once?

4 billion years is a LONG time.  Remember when Carl Sagan soothed us with the naturalist fable about “billions and billions of years” and “primordial soup” as an explanation for life’s origin?  Of course, now we know that was just a comforting materialistic bedtime story so children would go to sleep knowing that they really were just statistical accidents in space-time, and dream nice dreams about quarks and unlikely DNA.  Now we know there was no “primordial soup.”   We know that life appeared on Earth almost immediately from the moment earth’s temperature dropped below something like the interior of a jet engine.

And now the shoe is on the other foot.  Instead of the huge length of time being an argument for the accidental, spontaneous origin of life in some kind of improbable tango dance of amino acids, that enormous timespan is getting very difficult to explain as even being possible for life to have continued without destruction by nearby stellar events.  Supernovae are rare.  But, as Carl Sagan would say, when you have billions and billions of years, anything can happen… and usually does.  So why hasn’t it happened to Earth?

Here’s a current candidate for the job of terrestrial hitman.  This sort of thing is probably very rare.  But in 4 billion years, how rare does something have to be to happen now and then?

Just as important as the question of how life arose in a geological eyeblink after the end of the Late Heavy Bombardment is this:  why hasn’t life on Earth been wiped out, over and over, in the 3.9 billion years since it began?

Maybe Someone is looking out for us?

Remember to say “thank You” during your bedtime prayers tonight.  I know I will.

Where’s the outrage?

Category: abortion,left,media,science,terrorismharmonicminer @ 9:00 am

Animal activists torch home of Novartis chief

Anti-vivisectionists in Austria are thought to be behind a string of attacks on the Swiss-based pharmaceuticals giant Novartis.

In the most recent attack, on Monday in the Austrian town of Bach, activists are believed to have set fire to the holiday home of the company’s chief executive officer, Daniel Vasella. A fire accelerant was found at the scene, suggesting it was started deliberately, reports Reuters.

Last week, activists desecrated the graves of Vasella’s parents, stealing an urn containing the remains of his mother. That echoes a similar incident in the UK in 2004, when activists dug up a coffin and stole the remains of a woman whose family had run a business breeding guinea pigs for research.

If this had been done to an abortionist, it would have made major headlines around the world, accompanied with bloodcurdling cries of “terrorist!” and dark comparisons to “religious fundamentalists” who have violent tendencies.  Of course, in this case, since the religion in question is earth-worshipping paganism, and the target was the CEO of an evil corporation (never mind that abortion is ALSO big business, VERY big business, but one that is considered holy by some people), no such connections will be made.

In Austria, the activists also left the message “Drop HLS Now” on the headstone of Vasella’s mother’s grave, a warning for Novartis to cease funding animal experiments at Huntingdon Life Sciences – a company in the UK that conducts animal experiments for pharmaceutical companies.

Huntingdon Life Sciences has been the focus of a huge campaign by activists whose leaders are now mostly in jail following trials last year. But Novartis says it has not worked with HLS for years.

About three weeks ago, graffiti attacking Novartis and Vasella was scrawled over the church in Vasella’s village of Risch in central Switzerland. According to CNBC, messages have also been left on roads (with video) near Vasella’s home, including: “Vasella is a killer”, “We are watching you”, “Death to Vasella”, and “We’ll be back”.

What’s really crazy: this sort of talk wouldn’t even qualify as “hate speech” under the USA hate speech laws that the Democrat congress is trying to ram through. That’s because people who support basic medical research that saves lives are not a protected group.

Exit question: did you hear about this story ANYWHERE else in the media? If you did, did it get anything like the play it would have gotten if it was about something done to an abortionist? This post is going to be posted about two weeks after the events. So there will have been plenty of time for the coverage to happen…. if anyone cares.

Class dismissed.
