ether
1398, from L. æther "the upper pure, bright air," from Gk. aither
"upper air," from aithein "to burn, shine," from I.E. base *aidh- "to
burn" (cf. Skt. inddhe "burst into flames," O.Ir. aed "fire," L.
aedes, see edify). 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 1757 on a
volatile chemical compound for its lightness and lack of color (its
anesthetic properties weren't fully established until 1842).

support waves--which come in massive plasmòns--it's neither empty/void
nor heftles.

And Laurent, you should already know my mathematic proof which lets
the acceleration of matter to celerity with finite energy.
