The name ther suggests a far more subtle or penetrating and ultra-material kind of substance. Newton employs the term for the medium which fills spacenot only space which appears to be empty, but space also which appears to be full; for the luminiferous ether must undoubtedly[xii] penetrate between the atomsmust exist in the pores so to speakof every transparent substance, else light could not travel through it. The following is an extract from Newton's surmises concerning this medium: That the ether, if there be such a thing in space, can pass readily into or through matter is often held proven by tilting a mercury barometer; when the mercury rises to fill the transparent vacuum. Everything points to its universal permeance, if it exist at all. ......Buy Now (To Read More)
