Its good to see "unprecedented precision" stated.
Neutrinos are lighter than 0.8 electronvolts: Experiment limits neutrino mass with unprecedented precision
Max Planck Society
"The international KArlsruhe TRItium Neutrino Experiment (KATRIN), located at Karlsruhe Institute of Technology (KIT), has broken an important barrier in neutrino physics that is relevant for both particle physics and cosmology. Based on data published in the journal Nature Physics, a new upper limit of 0.8 electronvolt (eV) for the mass of the neutrino has been obtained. This first push into the sub-eV mass scale of neutrinos by a model-independent laboratory method allows KATRIN to constrain the mass of these "lightweights of the universe" with unprecedented precision.
Neutrinos are arguably the most fascinating elementary particle in our universe. In cosmology they play an important role in the formation of large-scale structures, while in particle physics their tiny but non-zero mass sets them apart, pointing to new physics phenomena beyond our current theories. Without a measurement of the mass scale of neutrinos our understanding of the universe will remain incomplete. [. . .]"

Regarding the last sentence in the 2nd paragraph of the article:
"Without a measurement of the mass scale of neutrinos our understanding of the universe will remain incomplete."
This article left me in the dust (way above my pay-grade) but seriously, Do we as human beings really think we would ever, I mean EVER, possibly have a "Complete" understanding of the universe?

Good stuff, don't know if you've gotten into some of the truly fascinating results in the tests involving neutrinos and quantum physics. Thanks for the share.

Yes, the kind of thing that you have to read 3 or 4 times to get an inkling. There is also a good YouTube series on this, try https://www.youtube.com/watch?v=7fgKBJDMO54

PO2 Marco Monsalve - Thank you very much for the link to the series. The description is fascinating.
"This video is about the phenomenon of neutrino oscillations, which is where neutrinos can change flavors (ie, change between electron, muon, or tau neutrinos) because those interaction states are in non-trivial superpositions of the free traveling/mass eigenstates (

New research paper coming soon - Scale Invariant Unification of Forces, Fields & Particles in a Quantum Vacuum Plasma

PO2 Marco Monsalve Hmm . . . here is the rest of my previous comment that is missing, up above:
The neutrino oscillating sounds similar to vacuum fluctuations at Planck scale - as the cosmological "fabric" of the universe. Perhaps the energetic activity always going on in "empty space" is the energy of neutrio oscillations popping into particles of other flavors. I was just reading an article yesterday about research aiming to measure the smallest measurable oscillation.
Here's a link to a brief abstract of a paper soon to be published about "scale invariant unification: Basically it is:
"The resulting scaling from the Planck scale to the universal scale finds a surprisingly periodic fit to organize matter in the universe. As a result, we can compute exact values defining the fundamental scaling factors of physical interactions."
