A recent measurement of the neutron magnetic dipole strength showed that it was far smaller than theory predicted.

Some theories that predict more matter than antimatter, "the baryon asymmetry problem" require a magnetic dipole for the neutron. Those theories seem to have been "disproved".

The writeup mentions that more theories (about EDM) in physics have been disproven than proven and that by itself points to a new direction ie: new physics is required to solve this problem. Unlike "global warming", where less snow proves global warming and so does more snow, theories explaining how things work can be disproven.

Side thought: Was reading a post in this sub-forum about antimatter and gravity, several experiments at CERN on gravity were mentioned. I got to wondering if the beam of antimatter could be run clockwise and then counter-clockwise and a possible beam "tilt" observed. The existence of a tilt would indicated a repulsive force just like the motion of an electron in a magnetic field.
