Neutrino masses are weird. First we thought neutrinos were massless. Then we thought they had positive mass. Then some evidence pointed to an IMAGINARY mass, which was crazy. That went away when...
Does this imply something about gravitational properties of antimatter?
For example, whether it's possible or impossible that gravitational force between matter and antimatter makes them repel each other.
