Evidence for gravitational lensing in IceCube-211208A counterpart PKS 0735+178 - #neutrino lensing proposed: https://academic.oup.com/mnras/article/549/2/stag658/8697604?login=false -> "Gravitational lensing explains why this blazar is detected at this time as a neutrino emitter: a magnification factor of about 10 can move an otherwise sub-threshold neutrino flux above the alert threshold."

What Would Happen if the Sun Stopped? Part 4: Black Hole Sun

Switch off fusion and, for ten thousand years, nothing happens. Then the Sun begins a slow, strange death: shrinking, briefly brightening, and coasting on gravitational heat for tens of millions of years. And the neutrinos give the whole thing away in just eight minutes.

“Shadow Blaster” Galaxy Might Have Sent High-Energy Neutrino to Earth

A star-forming galaxy in the early universe might have sent a ghostly particle known as a neutrino crashing into the ice at Earth’s South Pole, after an 11 billion-year journey through space. The pos...

A strange ‘#neutrino force’ helped heal a crack in #particlephysics
#Neutrinos and other #particles can produce a subtle force, relevant for precise measurements
Effect not limited to neutrinos. Electrons and other particles could transmit similar forces. It’s counterintuitive, because those particles are not type commonly associated with transmission of forces, according to particle physicists’ well-established theory, called the #standardmodel.

A strange ‘neutrino force’ helped heal a crack in particle physics

A neglected force produced by neutrinos and other particles helps atomic physics measurements align with predictions of the standard model.

So what makes a neutrino oscillate: forces internal to the neutrino alone, internal forces reacting to external forces, external forces alone, or combinations thereof?
If it's related to mass, some mass-energy must be added from somewhere, or dumped off to somewhere, right?
