Scientists have produced the firmest evidence yet of so-called sterile neutrinos, mysterious particles that pass through matter without interacting with it at all.
The first hints these elusive particles turned up decades ago. But after years of dedicated searches, scientists have been unable to find any other evidence for them, with many experiments contradicting those old results. These new results now leave scientists with two robust experiments that seem to demonstrate the existence of sterile neutrinos, even as other experiments continue to suggest sterile neutrinos don't exist at all.
That means there's something strange happening in the universe that is making humanity's most cutting-edge physics experiments contradict one another.
Sterile neutrinos
Back in the mid-1990s, the Liquid Scintillator Neutrino Detector (LSND), an experiment at Los Alamos National Laboratory in New Mexico, found evidence of a mysterious new particle: a "sterile neutrino" that passes through matter without interacting with it. But that result couldn't be replicated; other experiments simply couldn't find any trace of the hidden particle. So the result was set aside.

Did the same thing with plutonium - it didn’t exist either.
“The mass of the heaviest neutrino is roughly 0.05 eV, the mass of the next is somewhere between 0.01 eV and 0.0001 eV, and the third has a mass significantly less than these two values. For comparative purposes, the lightest non-neutrino particle is the electron with a mass of 511,000 eV.”

Terrible headline.
If it’s observed to exist then it’s supposed to exist.
The missing-solar-neutrino question has been answered; the explanation is called "neutrino oscillation," and has so far generated two Nobel prizes, one for the discovery of the "missing" neutrinos, and the other for the experimental proof that there are actually three different types of neutrino, and that each neutrino oscillates between three different types as it flies through the universe.
Only one of the three was detected by the Homestake mine experiment; by missing the other two, that detector seemed to detect only one-third the number of neutrons that were expected from the sun.
The Standard Model has lasted much longer than anybody expected. It’s always been considered to be incomplete:
The existence of a sterile neutrino would revolutionize physics from the smallest to the largest scales. It would finally break the Standard Model of particle physics that has reigned since the 1970s. It would also demand “a new standard model of cosmology,” Dodelson said. “There are other potential cracks in the standard picture,” he added. “The neutrino paradox could point our way to a new, better model.”

How do you detect something that doesn’t interact with anything?
“For comparative purposes, the lightest non-neutrino particle is the electron with a mass of 511,000 eV.”
“Therefore, heavy sterile neutrinos would have a mass of at least 45.6 GeV.”
Well, those, at least, are sizable.
When I came home last night at three
The man was waiting there for me
But when I looked around the hall
I couldn’t see him there at all!
Go away, go away, don’t you come back any more!
Go away, go away, and please don’t slam the door... (slam!)
Last night I saw upon the stair
A little man who wasn’t there
He wasn’t there again today
Oh, how I wish he’d go away...

Cool, it indicates physics physics beyond the Standard Model.

Should be called the "Adolescent Particle."
One Fine Day
Ladies and gentlemen, skinny and stout,
I will tell you a story I know nothing about.
Admission is free, so pay at the door.
Pull up a chair and sit on the floor.
One fine day in the middle of the night,
Two dead boys got up to fight.
Back to back, they faced each other,
Drew their swords and shot each other.
A blind man came to watch fair play.
A mute man came to shout “Hurray!”
A deaf policeman heard the noise,
And came and killed the two dead boys.
(He lived on the corner in the middle of the block,
In a two-story house on a vacant lot.)
A guy with no legs came walking by
And kicked the policeman on his thigh.
He crashed through a wall without a sound
Into a dry ditch where he promptly drowned.
A long black hearse came and carted him away,
So he ran for his life and is still gone today.
I watched from the corner of a big round table,
The only eyewitness to the facts of my fable.
And if you don’t believe my lies are true,
Ask the blind man; he saw it, too.

biblical basis for particles:
John 20:19-20 New Living Translation (NLT)
Jesus Appears to His Disciples
19 That Sunday evening[a] the disciples were meeting behind locked doors because they were afraid of the Jewish leaders. Suddenly, Jesus was standing there among them! “Peace be with you,” he said. 20 As he spoke, he showed them the wounds in his hands and his side. They were filled with joy when they saw the Lord!
The Millenial Particle!............................
True that. I hate the way they use the word just as if it happened moments ago rather than the weeks or more since it actually happened.
I remember a high school teacher telling me that with the rotational nature of atoms that it would physically, though improbable, be possible to drop a pencil through a table.
So I’m trying to figure out if a particle that can pass through matter would be an unknow element (Very unlikely.) or a particle formation that heretofore has never been observed.
I’m surprised a concept like this has gone unexplored for as long as there have been physical scientists and theoretical physics.
I was gonna ask that but got distracted by all the flags around the building.
Maybe its the “absence of interaction” they are looking for? Then, of course, they can say it means anything they desire.
