Neutrinos vs. Photons: Who wins the race across the galaxy?
https://en.wikipedia.org/wiki/Neutrino
And it made me curious.
The wiki article says that neutrinos travel at ...

Neutrino oscillations imply neutrino mass — Does the usual argument really hold?
An argument that people put forth is that because neutrinos can undergo changes in lepton flavor midflight, they must "experience time." Since massless particles must travel at the speed of ...

Neutrino's relativistic four-momentum
In an exercise I have to solve there is an apparently contradiction that I can't figure out.
In a pion decay, where a muon and a neutrino are produced, conservation of quadric-momentum states:

Limiting the mass of the neutrino for a relativistic case
I came across a question that states
What mass would a neutrino need to still be relativistic today (T = 2.37K) ?
So for a particle to be relativistic we need $pc \gg mc^2$
Well Neutrino was ...
