A previous article [1] (1) presented the hypothesis that the electric dipole moment (EDM de) of the electron equals zero, (2) cited confirmation by a London group led by Jony Hudson [2] which reported measurements, with increased precision, of de = (-2.4 ± 5.7stat ± 1.5syst) x 10E-28 e cm, an EDM not statistically different than zero with a high degree of confidence, and (3) questioned the assumption that this result implied a spherical electron shape, without any consideration that other shapes could yield the same zero EDM result. For example, Fig. 1 shows three negatively charged objects (white circles) on a plane and equidistant from the orthogonal spin axis, which rotate counter-clockwise so its magnetic dipole moment points toward the viewer.

Now a second independent research group dubbed ACME headquartered at Harvard has confirmed the hypothesis again with even greater precision reporting a
de = (-2.1 ± 3.7
stat ± 2.5
syst) x 10E-29
e cm, further decreasing the probability that a small, yet non-zero EDM may be readily demonstrable
[3].
