This is about quantum entanglement.
Einstein called it "Spooky action at a distance."
In the case of photons being entangled,
changing the state of one of them instantly changes the other
at a distances measured in kilometers.
And I mean instantly!
Faster than the speed of light...
Hello jtbell :-)
Math is not my forte so please allow to confirm:
the divisor for magnetic field strength is distance cubed?
Or have I misunderstood?
