...

A medium of great elasticity and extreme tenuity, supposed to pervade all space, the interior of solid bodies not excepted, and to be the medium of transmission of light and heat; hence often called luminiferous ether.

Noun
a colorless volatile highly inflammable liquid formerly used as an inhalation anesthetic

Noun
a medium that was once supposed to fill all space and to support the propagation of electromagnetic waves

Noun

n.
A medium of great elasticity and extreme tenuity, supposed to pervade all space, the interior of solid bodies not excepted, and to be the medium of transmission of light and heat; hence often called luminiferous ether.

n.
Supposed matter above the air; the air itself.

n.
A light, volatile, mobile, inflammable liquid, (C2H5)2O, of a characteristic aromatic odor, obtained by the distillation of alcohol with sulphuric acid, and hence called also sulphuric ether.
