Edison seems to have noticed something of the kind in what he called 'etheric force.'
Human thought is an etheric wave of the same essential nature as the radio wave.
He points upward indeed, but to follow his direction is to discover only the void of etheric vacancy.
Many of his experiments with sound and etheric waves required absolute quiet and freedom from interrupting noises.
They could talk to one another through the etheric transmitters inside their helmets.
Wherever and however you may be placed, you are always and everywhere immersed in a flood of etheric vibrations.
Edison seems to have noticed something of the kind in what he called the etheric force.
We have organs to sensibly register the vibrations of an etheric force and even to weigh light.
This little gun is the projector for a new ray which I have discovered—an etheric vibration of extremely short wavelength.
The physical body has also an etheric double which duplicates in a more subtle way the constitution of the physical body.
late 14c., "upper regions of space," from Old French ether and directly from Latin aether "the upper pure, bright air," from Greek aither "upper air; bright, purer air; the sky," from aithein "to burn, shine," from PIE root *aidh- "to burn" (see edifice).
In ancient cosmology, the element that filled all space beyond the sphere of the moon, constituting the substance of the stars and planets. Conceived of as a purer form of fire or air, or as a fifth element. From 17c.-19c., it was the scientific word for an assumed "frame of reference" for forces in the universe, perhaps without material properties. The concept was shaken by the Michelson-Morley experiment (1887) and discarded after the Theory of Relativity won acceptance, but before it went it gave rise to the colloquial use of ether for "the radio" (1899).
The name also was bestowed c.1730 (Frobenius; in English by 1757) on a volatile chemical compound known since 14c. for its lightness and lack of color (its anesthetic properties weren't fully established until 1842).
