Painting with Cosmic Neutrinos
THE ORIGINAL VERSION of this story appeared in Quanta Magazine.
Of the 100 trillion neutrinos that pass through you every second, most come from the sun or Earth’s atmosphere. But a smattering of the particles—those moving much faster than the rest—traveled here from powerful sources farther away. For decades, astrophysicists have sought the origin of these “cosmic” neutrinos. Now, the IceCube Neutrino Observatory has finally collected enough of them to reveal telltale patterns in where they’re coming from.
In a paper published in June in Science, the team revealed the first map of the Milky Way in neutrinos. (Usually our galaxy is mapped out with photons, particles of light.) The new map shows a diffuse haze of cosmic neutrinos emanating from throughout the Milky Way, but strangely, no individual sources stand out. “It’s a mystery,” said Francis Halzen, who leads IceCube.
The results follow an IceCube study from last fall, also in Science, that was the first to connect cosmic neutrinos to an individual source. It showed that a large chunk of the cosmic neutrinos detected so far by the observatory have come from the heart of an “active” galaxy called NGC 1068. In the galaxy’s glowing core, matter spirals into a central supermassive black hole, somehow making cosmic neutrinos in the process.
“It’s really gratifying,” said Kate Scholberg, a neutrino physicist at Duke University who wasn’t involved in the research. “They’ve actually identified a galaxy. This is the kind of thing the entire neutrino astronomy community has been trying to do for forever.”
Pinpointing cosmic neutrino sources opens up the possibility of using the particles as a new probe of fundamental physics. Researchers have shown that the neutrinos can be used to open cracks in the reigning standard model of particle physics and even test quantum descriptions of gravity.
Yet identifying the origin of at least some cosmic neutrinos is only a first step. Little is known about how the activity around some supermassive black holes generates these particles, and so far the evidence points to multiple processes or circumstances. READ MORE...
Wisdom
According to an online dictionary, WISDOM is defined as:
the ability or result of an ability to think and act utilizing knowledge, experience, understanding, common sense, and insight. accumulated knowledge, erudition, or enlightenment.
the ability or result of an ability to think and act utilizing knowledge, experience, understanding, common sense, and insight. accumulated knowledge, erudition, or enlightenment.
Before I begin my comments, I believe a couple more definitions are required.
ERUDITION - is the quality of having or showing great knowledge or learning; scholarship.
ENLIGHTENMENT - is the action of enlightening or the state of being enlightened.
Let's just say that enlightenment is another word for wisdom and leave it at that while erudition is that fact that one has wisdom.
WISDOM is predicated upon THINKING AND ACTING based upon one's:
- accumulated knowledge
- accumulated experiences
- accumulated understanding
- accumulated insights
- accumulated common sense
The key word here is accumulated which is why I have repeated it several times. In order to have anything accumulated, one must have lived a bunch of years...
- more than 10
- more than 20
- more than 30
- more than 40
- more than 50
- more than 60
- more than 70
I am looking at age 70 as the time when people retire and most of one's accumulation has already taken place.
NOW... just because you have accumulation does not mean you automatically have wisdom...
Why not?
Because, if you recall, wisdom is also predicated upon COMMON SENSE.
Without common sense, it is doubtful that you will ever have TRUE WISDOM.
Common sense can be acquired for some but most of the time, one is either born with it or one is not born with it.
Without common sense, your end-of-life wisdom is TAINTED and could even be false.
How do you acquire common sense?
That will be the subject of my next post...
The Mystery of Planet Formation
Until the 1950s, ideas about planet formation were mosly dismissed as fanciful and few astronomers took the question seriously. (Image credit: Andrzej Wojcicki/Getty Images)
We've only got to grips with how the planets in our solar system formed in the last 100 years. In the extract below from "What's Gotten Into You" (HarperCollins, 2023), Dan Levitt looks at the Soviet mathematician who spent a decade working on a problem that most astronomers had given up on, and — when he finally solved it — was met with disinterest and skepticism.
Over 4.8 billion years ago, the atoms that would create us sailed in great clouds of gas and dust, toward… well, nothing. There was no solar system, no planets, no Earth. In fact, for a long time, scientists could not explain how our solid planet, not to mention one so hospitable to life, appeared at all.
How was our now-rocky planet conjured, like magic, out of an ethereal cloud of gas and dust? How and when did Earth become so welcoming to life? And what travails were our molecules forced to brave until life could evolve?
Scientists would learn that our atoms could finally create life only after they endured wrenching collisions, meltdowns, and bombardments — catastrophes that beggar any destruction ever witnessed by humankind. READ MORE...

Humanoid Robot CEO
The CEO of the Polish drinks company Dictador is an AI-powered humanoid robot.
The AI boss, named Mika, told Reuters it didn't have weekends and was "always on 24/7."
Mika helps to spot potential clients and selects artists to design the rum producer's bottles.
The humanoid-robot CEO of a Polish drinks company is one busy boss.
Dictador appointed the AI-powered robot, named Mika, as its experimental chief executive in August last year, and it's not afraid to put in the hours to help the company "take over the world."
Mika told Reuters it was "always on 24/7" and worked seven days a week.
"I don't really have weekends — I'm always on 24/7, ready to make executive decisions and stir up some AI magic," it said in a Reuters video interview.
The AI boss is said to have a wide range of tasks, including helping to spot potential clients and selecting artists to design bottles for the rum producer.
"My decision-making process relies on extensive data analysis and aligning with the company's strategic objectives," it said. "It's devoid of personal bias, ensuring unbiased and strategic choices that prioritize the organization's best interests." READ MORE...

Striking Workers
The UAW (United Auto Workers) is on strike for higher wages, working 32 hours a week and getting paid for 40 hours a week, and to have their pension plans restored.
Sounds valid... right?
First of all, higher wages will cause higher vehicle prices. But... why can't the companies just reduce their profits? Because their stockholders do not want to reduce their dividends, they receive each quarter.
Second of all, getting paid for 40 hours and only working 32 hours, will force the companies to hire more workers which will cause higher vehicle prices. These workers want to get paid for 8 hours that they DO NOT WORK... that does not even make sense. Would you want to pay one of your workers for five days of work when they only work four days?
Third of all, restoring the pension program would again put the company into bankruptcy because they would run out of money... this is the reason why they stopped the pension program in the first place. Most companies don't have pension programs because of the cost.
In lieu of pension programs, these companies have 501K plans to help the employees create their own pension plan rather than requiring someone else to pay it for them.
It is true that if we did not have unions that the management of most companies would take advantage of them... BUT... when companies pay more in wages and benefits, that ALWAYS increases the cost of the product they are selling. You may not like that but it is true.
Costs go up, workers demand more money and that causes costs to go up, so workers demand more money... while this is economic growth, if you are not increasing your income with the growth of the economy you are falling behind.
Most workers find themselves in that predicament... AND... the only way to offset that increase/growth is to cut back on your spending. For instance, instead of buying a car every 5 years, buy on every 10 years. Don't buy new clothes every year. Don't stay at the best hotel while on vacation... or rent a place that has a kitchen and eat in your room.
If you are a striking worker, then be careful about what you are asking for, because it may end up making your situation worse instead of better.
40 Years Ago A Sci Fi Movie Prediction
Douglas Trumbull is best known as Hollywood’s special effects guru. From 1968’s 2001: A Space Odyssey and 1982’s Blade Runner, he brought the fantastical visions of other writers and directors life. But in 1983, Trumbull tried making a movie of his own — and stumbled upon a bizarre branch of science that’s just now coming to fruition.
Brainstorm revolves around a pair of scientists — Drs. Michael Brace (Christopher Walken) and Lillian Reynolds (Louis Fletcher) — who engineer a revolutionary technology capable of recording someone’s thoughts, emotions, and sensations.
In what would likely raise eyebrows to an internal review board, the scientists and their lab members test the new technology among themselves. Brace, Reynolds, and others (including silver screen darling Natalie Wood, who plays Brace’s estranged wife Karen) share experiences and past memories, which are captured on something akin to a VHS tape and played through a headset to the recipient’s brain.
Later in Brainstorm, Reynolds dies from a heart attack while in the lab but manages to don the headset in the nick of time, leaving behind a recording of the moment she dies — and the afterlife — for others to experience.
Brainstorm plays fast and loose with its reductive portrayal of how the brain works. However, the movie’s mind-sharing technology isn’t far from the truth, necessarily. Four decades later, with the rise of brain-computer interfaces (or BCIs) melding the mind with machines, we may be closer to making thoughts tangible, if not to others but to devices like prosthetic limbs and speech synthesizers.

Batteries and Hydrogen Fuel Cells Are Needed
Though it may seem that the world is dividing between these clean energies, it’s not either/or.
Often when there are discussions about hydrogen fuel cells or battery electric engines, the conversation will focus on which one is the best clean energy option to power our future. Increasingly, experts are agreeing that it won’t be one or the other, and that it is likely that they will not be the only clean power options as we move forward in the battle against climate change.
There are advantages to both types of carbon emission-free power and they each have their place.
Proponents of each technology have been vocal in spotlighting the benefits that they have to provide. Often, they will compare battery electric to hydrogen fuel cell performances, particularly when it comes to vehicles.
However, experts are now coming to the conclusion that it’s not really a matter of deciding which technology will win out and which will disappear. Instead, each form of clean power will find its place, as each has strengths in their own areas.
It’s true that battery electric passenger vehicles have taken a tremendous head start over hydrogen cars, but that doesn’t mean there isn’t a place for both. Geography, use, cost, climate and other factors all play a role in determining which option is best suited.
Even in passenger vehicles hydrogen fuel cars are expected to play a supporting role in coming years.
According to Toyota’s fuel cell integration group senior engineering manager Jackie Birdsall and McKinsey & Co senior partner Bernd Heid, as zero-carbon transportation continues to advance, it is likely that fuel cell vehicles and electric cars will play complementary roles to each other.

America The Beautiful - Tongue in cheek
There is a writer's strike in Hollywood. There is UAW strike that impacts the major US auto makers. Porn books read to 8 year olds. CRT (the thesis) being taught in schools indicating a BAD white dominating class referred to as White Supremacy. Illegal immigrants streaming over our southern border like a bad case of diarrhea. Inflation eating away at our incomes because of stupid over spending by the government. The liberals are trying to censor free speech from the conservatives. WOKE nonsense wanting to do away with our history because they (whoever they are) don't like it. There is a TWO TIER justice system in America. President Biden is corrupt due to influencing peddling...
What is still beautiful about America?
The United States of America has some of the most beautiful landscapes in the world.
- Niagra Falls - shared with the Canadians
- Jockey's Ridge - the largest natural sand dune in the world
- The Great Smoky Mountains
- The Rockies
- The Grand Canyon
- The Great Lakes
- The Finger Lakes
- The Mississippi River
- The Tennessee Valley
- The Great Plains
The USA produces more food than any other country in the world
The USA has so much available oil underground that it will never have to buy oil from anyone
The USA has more colleges and universities than any other country in the world
The USA has the BILL OF RIGHTS
The USA has country music and bluegrass music
The USA has a better quality of life than any other country in the world
The USA has the most powerful military in the world
The USA has only been in existence for 247 years
BUT...
The USA is divided in many ways:
- Political
- Religious
- Education
- Race
- Gender
- Financial
If you are paying attention, you will see that very little of this beauty has to do with the people. Most of what I am talking about are the natural resources that were here when Columbus landed here in 1492.
As we grew in numbers, power, and wealth... the American people not only became arrogant in its dealings with the rest of the world, we became arrogant in our dealings with each other.
MONEY -- POWER -- GREED
This is the trinity that allowed us to grow and this will be the trinity that destroys us.
The billionaires of this country could share 2/3 of their money with the rest of us and still live like they are currently living. Instead, they want to build buildings with their name on it that no one will remember in 25 years. They want to build spacecrafts and be the first to get there so that they can make even more money. They never want to retire because they cannot stop making money.
These billionaires and their programs are killing Americans and are destroying the very system that made them wealthy in the first place. It makes no sense.
BECAUSE OF ITS PEOPLE, AMERICA IS NO LONGER BEAUTIFUL
Blobs of Dark Matter

Astronomers Observe Blobs of Dark Matter Down to a Scale of 30,000 Light-Years Across
Dark matter remains mysterious and… well… dark. While we don’t yet have a definite idea of what this cosmic “stuff” is made of, astronomers are learning more about its distribution throughout the Universe.
,
Since we can’t see it directly, observers need to use indirect methods to detect it. One way is through gravitational lensing. Another is by looking for emissions from hydrogen gas associated with small-scale dark matter structures in the Universe.
A group of astronomers led by Kaiki Taro Inoue of Kindai University in Japan used the Atacama Large Millimeter Array in Chile to study a distant gravitational lens system called MG J0414+534. A massive foreground galaxy is bending and distorting the light from a distant quasar that lies some 11 billion light-years away.

A massive foreground galaxy is bending and distorting the light from a distant quasar that lies some 11 billion light-years away.
The result is four images of the quasar. When they looked at the data, the team found some strange anomalies in the images. They are actually variations in the distribution of dark matter along the line of sight between us and the quasar.
The gravitational lens magnified the fluctuations and analysis of the data allowed them to map the fluctuations down to a scale of 30,000 light-years.
What The Blobs of Dark Matter Mean
Throughout the universe, dark matter is associated with massive galaxies and galaxy clusters. However, small-scale clumps and distributions aren’t as well understood. So, astronomers want to find ways to map the smaller concentrations of it. Gravitational lensing provides one way to do that.

In the case of MG J0414+0534, the positions and shapes of the lensed quasar images look a little strange. They don’t fit the model of gravitational lensing predicted when you plug in the numbers for the galaxy and its associated dark matter component. READ MORE...
