Weak forces edit
The weak interaction is expressed with respect to nuclear electrons and the continuous β-ray emission spectrum of β decay.[1]
"The observation of a neutrino burst within 3 h of the associated optical burst from supernova 1987A in the Large Magellanic Cloud provides a new test of the weak equivalence principle, by demonstrating that neutrinos and photons follow the same trajectories in the gravitational field of the galaxy."[2]
