Voyager Spacecraft Detect an Increase in The Density of Space Outside The Solar System
. . . Actually, what they are measuring is the electron density in free space as it varies with distance from the sun
Curious, I've not heard of a rule that says # of electrons = # of protons. Is this evidence of a charge imbalance in the Universe?
IIUC, they are not equal only in isotopes :
@FearlessFly Is that the article you intended, it was about ions, not isotopes.
@EdEarl . . . I stand corrected
