However, Victorian scientists did think there was something called the luminiferous ether.
As late as 1884, Lord Kelvin expressed the view of virtually all physicists that electromagnetic fields required a physical medium in space, known as the luminiferous ether, by which they could manifest their wave properties.
The koilon in which all these bubbles are formed undoubtedly represents a part, and perhaps the principal part, of what science describes as the luminiferous æther.
The existence of an all-pervasive medium called the luminiferous ether was launched as a theory.
It has the best possible reasons for rejecting the idea of luminiferous particles; but, in support of the conclusion that the celestial spaces are occupied by matter, it is able to offer proofs almost as cogent as those which can be adduced of the existence of an atmosphere round the earth.
