...Keeler, with more powerful instruments, disproved the supposed coincidence. Lockyer considers that "all self-luminous bodies in the celestial space are...vapour being finally condensed into a solid globe." Lockyer divided the stars into seven groups, according to temperature, the order of evolution being...

...published in 1890. The fundamental principle involved in this theory was that "all self-luminous bodies in celestial space are composed either of swarms of meteorites or of masses of meteoritic vapor produced by heat." This theory was the result of spectroscopic studies. Lockyer claimed...

...according to this hypothesis, "are composed either of swarms of meteorites or of masses of meteoritic vapor produced by heat. The heat is brought about by the condensation of meteor swarms due to gravity, the vapor being finally condensed into a solid globe." * According to this theory the light of the nebulae...

...Meteoric Hypothesis " — communicated to the Royal Society in 1887 — all self-luminous bodies in celestial space are composed either of swarms of meteorites...or of masses of meteoric vapour produced by heat. On this assumption he divided the stars into seven groups, commencing with nebulae and gaseous bodies,...

...on Schiaparelli's discussions on ' the local concentration of celestial matter ', concluded that ' all self-luminous bodies in the celestial space are...composed either of swarms of meteorites or of masses of meteoritic vapour produced by heat. The heat is brought about by the condensation of meteor swarms...

...interpenetrate. 286 however, still held fast to the meteoritic hypothesis and even widened it, proposing that 'all self-luminous bodies in the celestial space are...or of masses of meteoric vapour produced by heat. New stars ... are produced by the clash of meteor swarms.' Variable stars were meteor swarms orbiting...

...his was the meteorite hypothesis. He believed that "all self-luminous bodies in the celestial spaces are composed either of swarms of meteorites or of masses of meteoric vapour produced by heat". Starting from this idea, he developed an elaborate picture of the origin and the evolution of nebulae...

...Hypothesis', eventually expounded in his book with that title published in 1890; the idea was that 'all self-luminous bodies in the celestial space are...composed either of swarms of meteorites, or of masses of meteoritic vapour produced by heat' - in other words, the primordial matter from which — METALLIC...
