Baryons, Gravity Waves

These are exciting, or disquieting, times.

Which it is depends partly on how much a person likes living in a world where scientific knowledge is rapidly changing.

I like it, a lot....

...Since this is a "religious" blog, I'll be discussing — briefly, for me — how my faith relates to experiments using CERN's Large Hadron Collider and science in general....

Earliest Life: Maybe

We're not sure how skulls found in central China fit into the family tree. They're a bit like Neanderthals, a bit like folks still living in that part of the world, and not quite like anyone else.

Other scientists found what may, or may not, be the oldest evidence of life found so far. That's in Quebec, Canada.

TRAPPIST-1: Water? Life??

TRAPPIST-1's planets may support life: or not. We don't know. Not yet.

We're pretty sure that all seven are rocky worlds, like the Solar System's inner planets.

Three are in the star's habitable zone. The inner two definitely do not have one sort of atmosphere that would make life as we know it impossible.

Even if we don't find life there, we'll learn a great deal while looking.

Face Transplant at Mayo

Andy Sandness wasn't born looking like that. He's lived with the consequences of a "wrong choice" for more than a decade.

Agreeing to get Mayo Clinic's first face transplant won't undo his decision. But now he has a second chance for a normal life.

Pollution: Still Learning

Scientists found PCBs and PBDEs in deep-sea critters, armyworms are on the march in Africa, and Mexico City's air isn't as clean as we'd hoped.

Rational concern seems reasonable....

...Last week I talked about blaming our tools for our mistakes. (February 10, 2017)

This week I'll revisit Lovecraft's "placid island of ignorance,"sort of....

Bogs and Bison

The good news is that bison are back in Banff, and Britain's bogs may bounce back, too. Keeping wetlands wet isn't what many folks had in mind, back in my youth.

But as I keep saying, we've learned quite a bit since then....

...This post's afterword is a quick look at how folks have perceived natural resources, plus a bit about pessimism and being human....

Footprints in Ancient Ash

Scientists are pretty sure that Saccorhytus coronarius is an ancestor of lancets, sea squirts, fish, amphibians, reptiles, dinosaurs, and mammals: including us.

Much more recently, about 3,660,000 years back, five Australopithecus afarensis strolled across volcanic ash. One of them was "astonishingly larger" than any other A. afarensis we know of. Exactly what that means isn't, I think, clear. Not yet.

Making a Universe: Why Bother?


"The heavens declare the glory of God; the sky proclaims its builder's craft." (Psalms 19:2)
Okay, so who is this message proclaimed to?

Us, apparently.

One of the ways we can learn about God is by noticing order and beauty in the universe. (Catechism of the Catholic Church, 31-32, 319)

St. Bonaventure said that the universe communicates God's glory, St. Thomas Aquinas said that the Almighty creates because God is good and loving. (Catechism, 293)

I think they're right.

Gems, Metal, and Earth's Core

The Fire of Australia, a whacking great chunk of opal, isn't particularly interesting from a 'science' viewpoint.

But I'm human, which is probably why anything big and shiny gets my attention: including that rock.

Wrenching myself back on-topic, scientists found a stream of liquid metal flowing at the edge of Earth's core. Studying it may help us learn why Earth's magnetic field flip-flops at apparently-irregular intervals. What we'll learn is beyond me: we didn't know much about geomagnetic reversal when I started school.

We still don't, for that matter. As I keep saying, there is a very great deal left to learn.

Urban Evolution and Big Brains

Life, and evolution, has been happening for quite a while. Cities are new, but the same processes happen there; with slightly different results. We're learning how urban environments affect critters, and are piecing together more of humanity's story....

...I see no problem with believing that God is creating a universe that's following knowable physical laws. That's just as well, since it's what we're told to believe....

Epiphany Sunday



Statues1 of Caspar, Melchior, and Balthazar started near the clock in our living room. I took those pictures of them on Wednesday. Their trip to the nativity scene ended today, Epiphany Sunday.

We read about "magi from the east" in today's Gospel: Matthew 2:1 through 12:
"1 When Jesus was born in Bethlehem of Judea, in the days of King Herod, 2 behold, magi from the east arrived in Jerusalem,
"saying, 'Where is the newborn king of the Jews? We saw his star 3 at its rising and have come to do him homage.'"
(Matthew 2:1-2)
"Magi" is how μάγοι, mágoi, looks in my native language. That's the Greek version of an Old Persian word that would sound something like "magus" if I tried pronouncing it.

SETI: What If?

Contacting extraterrestrial intelligence, meeting people whose ancestors developed on another world, has been a staple of pulp fiction for generations.

Lately, it's become a matter for serious discussion. I'll be looking at an op-ed's take on how learning that we're not alone might affect folks with various religious beliefs. I'll also share what I expect: and what I don't....

Mars, Aliens, and SETI



I'd love to be talking about unambiguously artificial signals picked up by the Allen Telescope Array, or reports of a ship from beyond the Solar System settling into orbit around our moon.

But that hasn't happened, and probably won't. Not in my lifetime.

Instead, I'll talk about why I don't "believe in" extraterrestrial life; and do not assume that we are alone in the universe. That puts me in the third of folks who aren't sure, and I'll get back to that.

My 'Friday' posts are usually about more-or-less-current 'science news.' That won't happen this week. I've read a few interesting articles, and will be talking about them — after the Christmas-New Year's gymkhana is over.

This week I'm using material that didn't quite fit into an earlier post. I'll also talk about the Great Moon Hoax, Nicola Tesla and Martians; and what I think about life in the universe.

Jesus and Expectations



Pip's Christmas doesn't have much to do with Christmas, or Advent, but I figured this post should have something that looks 'seasonal.'

"...Blessed is the One Who Takes No Offense at Me"


We'll be hearing Matthew 11:2-11 this morning. The readings still aren't particularly 'Christmassy.'
"2 When John heard in prison 3 of the works of the Messiah, he sent his disciples to him "4 with this question, 'Are you the one who is to come, or should we look for another?'
"Jesus said to them in reply, 'Go and tell John what you hear and see:
"5 the blind regain their sight, the lame walk, lepers are cleansed, the deaf hear, the dead are raised, and the poor have the good news proclaimed to them. "And blessed is the one who takes no offense at me.' "
(Matthew 11:4-6)
Our Lord balanced that rebuke with a reminder of the Baptist's great function in Matthew 11:7-15, and a complaint about folks who wouldn't listen to John or Jesus....

Tides and Our Moon’s Origin

Scientists have been wondering how our moon formed, and why its orbit isn't over Earth's equator.

It looks like our moon formed after something about the size of Mars hit Earth, roughly 4,500,000,000 years back.

But the giant-impact hypothesis didn't explain why our moon orbits Earth only five degrees away from Earth's orbital plane. The math had said that our moon would be orbiting pretty much over Earth's equator....

...God is Large and In Charge


I occasionally wonder if I should keep explaining why reality doesn't offend me, and why facts don’t threaten my faith....

KIC 8462852 and Strange Stars

KIC 8462852, Tabby's Star, has been in the news recently. Scientists are pretty sure that something very large orbits the star, but haven't worked out what it is.

A few scientists, looking at the data, say that it's probably a really odd natural phenomenon: but that it might something built by folks who aren't human.

SETI, the Search for Extraterrestrial Intelligence, is still a science in search of a subject. But quite a few scientists are taking it seriously, which is why Berkeley SETI Research Center added few stars to the Automated Planet Finder's observing queue....

...What I say about SETI and science in general may take some explaining, if you're new to this blog. Basically, I think God is large and in charge; and that part of my job is appreciating God's work — not telling the Almighty how it should have been made...."

Olive Threat, Ginkgo Genome

Something's killing Europe's olive trees: a bacterium that's probably spread by insects. Scientists don't know how to stop the disease, not yet.

Other scientists analyzed the Ginkgo genome. What they found helps explain the tree's remarkable endurance.

Brain Implants and Rewired Monkeys

Someone from the Netherlands gained a small measure of freedom after learning to use a prototype computer-brain interface.

I see that, and experiments with rhesus monkeys, as a good thing....

...As usual, I'll also talk about why I don't think God is offended when we help folks....

Near-Earth Asteroids

Scientists spotted 2016 UR36 days before it passed by Earth. "Killer asteroids" headlines notwithstanding, we knew it would miss our planet by a comfortable margin.

Sooner or later, though, something big will hit Earth: again. We still can't prevent that, not yet.

Authority, Superstition, Progress


(From Diliff, via Wikimedia Commons, used w/o permission.)

Authority, superstition, and misapplied technophilia (it's a real word) rate at least one post each: but that'll wait until another day. Days.

This time I'll take a quick look at all three, and then say why I don't believe in Progress with a capital P — and don't yearn for the 'good old days.'
