Join the hunt for the universe’s most common-yet most elusive and baffling-particle. (Aired October 6, 2021)
Official Website: to.pbs.org/4b5VqIx | #novapbs
Outnumbering atoms a billion to one, neutrinos are the universe’s most common yet most elusive and baffling particle. NOVA joins an international team of neutrino hunters as they try to capture an elusive fourth form of neutrino. Their results may force scientists to redraw their blueprint of the subatomic world, the Standard Model of physics, and change our understanding of how the universe works.

What I find fascinating, are the instruments used to detect all the particles!!! Let alone the discovery of the particals themselves. To simply put it, WOW!!! Just simply WOW!
for people interested in this subject fermilab has a relatively large channel here on youtube. they go one step further than this documentary while avoiding the heavy math.

If a neutrino has mass then it is subject to gravity. "Dark matter" is therefore the NEUTRINO ATMOSPHERE of galaxies, and no longer a mystery. What a relief!
Exciting research, must be incredibly rewarding to publish results that can stand up to massive scrutiny! I'm glad the community eventually rewarded Ray Davis' work with the prize for his work and determination through the unknown problem.

Saying particles interact with each other perpetuates a model so oversimplified its limiting. What is described in the standard model are discrete patterns of excitation of quantum fields. Most quantum fields interact with each other, some dont. Trying to explain everything with point-like representations of those fields is silly. As we perceive them, they are only the final result of field interactions we do not perceive. Like describing what's happening in the cpu of a computer only looking at a handful of the screen's pixels, at random intervals.
Nice that neutrino play different tunes durin their journey through & around the maelstrom of the cosmos, they have purpose!

Perhaps neutrinos are the base electrical charge supporting this simulation. Perhaps we are in a bubble universe, completely isolated from all the other bubble universes, where all the missing, or dark, matter exists. Just a couple of thoughts.
GENERATING NEUTRINOS: (Besides the 'normal' way): Do my gravity test for my theory of everything idea, (canceling out 'em' of a high powered laser, thereby generating a mini gravitational black hole), but before the black hole would be generated, possibly a neutrino would be generated. Need to do the test to see if true or not.

It provided beams for CERN’s first experiments in particle and nuclear physics.” “The Proton Synchrotron (PS) accelerated protons for the first time on 24 November 1959, becoming for a brief period the world’s highest energy particle accelerator.”

The most exciting things would be to learn to talk to the messenger and also to learn dark matter and what is it and gravity. Both mind boggle me just how amazing they are. Wish I could live long enough to see the day science discovers these things. May be different generations from now. Or the near future. But would be so satisfying to reach source.

awesome vid!
Love this stuff!
We need to find more particles / we need to keep a lot of people working.
For the tail end of this VOD, it might be oscillations in the experiment.
Interesting ramification of the mass of the neutrino is, if we can create instrumentation for neutrinos sufficient we will be able to probe gravity at a particle level using the neutrinos. Of course these instruments are probably 10 to 20 years away but eventually the secrets of gravity at a quantum level will be revealed.

I want to say that somewhere I heard that a supernova happening somewhere in the Milky Way galaxy would set off our neutrino detectors , maybe shortly after we saw the flash of the supernova .

Close. We’d detect the neutrinos first. They’d leave the collapsing core and sail through the rest of the star, virtually unimpeded. Meanwhile the shockwave from the collapsing core, that tears the star apart, would take as much as an hour or two to reach the surface. Only at that point would the supernova become apparent visually.

That's going to be interesting - our neutrino detectors going nuts , giving us a heads up that a supernova has happened somewhere . And we are building these detectors thanks to the theorists like Fermi and Pauli , and also to the experimenters like Raines , Cowans , and that other guy . Pretty interesting !

I'm an amateur astronomer. If there's a supernova, the gravity waves and neutrinos from the explosion would arrive a few hours before the light does. I'm signed up to get an alert if there is a simultaneous detection of gravity waves and neutrinos from the same direction.

@colincampbell767 : What a spectacular and dramatic confirmation of several current theories THAT would be - amateur astronomers like you being alerted that the flash of a supernova is imminent ! Everyone contributing - the theorists with their calculations , predicting the existence of neutrinos and gravity waves , and the experimenters building the instruments to observe them . Very exciting . You amateur supernova hunters are making a major contribution , like Koichi Itagaki in Japan when he found the supernova in the " pinwheel galaxy " last May . But that one happened 21 million years ago , so perhaps too far to set off neutrino and gravity wave alarms way over here !

It's not a weird way of writing it at all. Not all mass is solid. Gases have mass, so do plasmas. So it does make sense to write "solid matter"--you have to define what state it's in.

I wonder if neutrinos have mass only after they've interacted with a Higgs field, or perhaps that interaction causes the neutrinos to change flavors?

If you consider the universe is full of neutrinos, photons, radiation and gravity waves all mixed together for billions of years I'd expect some interaction between all these different things. Dark mater and dark energy could be the result of these interactions. Since we just discovered the Higgs boson and didn't even know it might exist 75 years ago I'll bet ther's more to the story than we can even imagine!
I saw this guy on stargate the series the other day. He was a sci-fi director or something.
dark matter/energy are the particles already traveling through space like light energy(mass), gama, nuetrinos it fills the empty space which means if we can see and detect it ...its mass ...thats the dark matter

Well, considering that it’s been proven that antimatter exists, why not anti-neutrinos? Each flavor would have its opposite. That would certainly make a lot more sense, now wouldn’t it? You don’t have to try and shoehorn in a fourth particle when all you need is three other particles who are exact opposites of the detectable Lutrin’s.

In all we think we know about MATTER vs UNIVERSE. we know nothing! Since we are unable to access the unrecorded process of the evolving (expansion theory).. JWST threw a wrench into this theory by proposing never before postulations of observations! Simply, deep-time doesn't have a validated measurement of TIME itself! We cannot go back in time to watch it happen! We are relegated to "theories" we contrive!
