Quote: in radiation, the lines of force exist independently of other bodies; may be modified, bounded, propagate over time

Quotation

3247. When we turn to radiation phenomena, then we obtain the highest proof, that though nothing ponderable passes, yet the lines of force have a physical existence independent, in a manner, of the body radiating, or of the body receiving the rays. They may be turned aside in their course ... [They may be] turned on their axis ... Their sum of power is limited ... The lines have no dependence upon a second or reacting body, as in gravitation; and they require time for their propagation.   Google-1   Google-2
