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.

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.

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.”

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 .

@aajmgopher 3 ай бұрын

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.

@johnishikawa2200 3 ай бұрын

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 !

@colincampbell767 2 ай бұрын

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.

@johnishikawa2200 2 ай бұрын

@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 !

We cannot go back in time to watch it happen! We are relegated to "theories" we contrive!
