• Good old Newton spotted both problems already, in his Opticks,

  • his force law implies “action at a distance” which he thought strange
  • he thought (al)chemistry required something different, and worked on it.

• Maxwell’s equations have built-in waves carrying fields to a distance:

in vacuum, i.e. no free charges.

• Proof: Consider loops on two surfaces related to two planes separated in space and time, E(y,z):
