The study of electric dipole moments (EDMs) offers a unique window into the violation of time-reversal symmetry, an effect that, when coupled with charge-parity (CP) violation, presents fundamental ...

Measuring zero: scientists have lowered the previous upper limit of the neutron’s electric dipole moment by 40%. (Courtesy: IOP Publishing) For more than 60 years, physicists have been searching for a ...

Incompatible moments A spinning charge (left) acts like a loop of current to produce a magnetic dipole moment (blue arrow). Distorting the electron's charge distribution (middle) produces an electric ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. Most of the coverage of this adopts the framing of talking about this ...

The most precise measurement yet of the electron’s shape casts doubt on ideas such as supersymmetry that predict a zoo of undetected particles in the universe Scientists are unanimous that their ...
