Nebular   Listen
adjective
Nebular  adj.  Of or pertaining to nebulae; of the nature of, or resembling, a nebula.
Nebular hypothesis, an hypothesis to explain the process of formation of the stars and planets, presented in various forms by Kant, Herschel, Laplace, and others. As formed by Laplace, it supposed the matter of the solar system to have existed originally in the form of a vast, diffused, revolving nebula, which, gradually cooling and contracting, threw off, in obedience to mechanical and physical laws, succesive rings of matter, from which subsequently, by the same laws, were produced the several planets, satellites, and other bodies of the system. The phrase may indicate any hypothesis according to which the stars or the bodies of the solar system have been evolved from a widely diffused nebulous form of matter.

"Nebular" Quotes from Famous Books



... but few facts to guide one's guesses. But the trip yonder is worth making, if only to learn that. I do not incline to the opinion that their civilization is vastly older and more developed than ours. Granting the nebular theory of the origin of the universe (which is, after all, only a guess), it is not even then certain that Mars was thrown off the central sun before the Earth. It is much smaller, and may have been thrown off later ...

... and having local whirls revolving with the satellites. As Delambre and Grant have said, this fiction only retarded the progress of pure science. It had no sort of relation to the more modern, but equally misleading, "nebular hypothesis." While many were talking and guessing, a giant mind was needed at this stage to make ...

... top, and again disappearing when it emerges into warmer air. The cloud emerges from the imperceptible as heat is dissipated. It is dissolved again as heat is absorbed and the watery particles evaporate. Spencer esteems this an analogue of the appearance of the universe itself, according to the nebular hypothesis. Yet assuredly, as the cloud presupposes vapours which had previously condensed, and the vapour clouds that had previously evaporated, and as clouds dissolve in one place even at the moment that they are forming in another, so we are told ...

... "Principia" is a chapter on mosses wherein it is explained how the first vestige of lichen catches the dust particles of disintegrating rock, and we get the first tokens of a coming forest. Darwin never made a point better; and the nebular hypothesis and the origin of species are worked out with conjectures, fanciful flights, queer conceits, poetic comparisons, far-reaching analogies, and most astounding leaps ...

... mathematical astronomy would not exist. Our calendar would still be in all essential respects as it is now; our year with the solstices and equinoxes as its cardinal points. The texture of our poetry might conceivably be the poorer without its star spangles; our philosophy, for the want of a nebular hypothesis. These would be the main differences. Yet, to those who indulge in speculative dreaming, how much smaller life would be with a sun and a moon and a blue beyond for the only visible, the only ...

... and groups, or to grand groups like the Milky Way. Nebulae may have any of the forms which have been described; and, in 1811, he gives examples of immense spaces in the sky covered with diffused and very faint nebulosity. "Its abundance exceeds all imagination."[38] These masses of nebular matter are the seats of attracting forces, and these forces must produce condensation. When a nebula has more than one preponderating seat of attracting matter, it may in time be divided, and the double nebulae have had such an origin. When nebulae appear to us as round ...

... not accomplished automatically as scientists would have us believe,—an assertion which has been proven in The Rosicrucian Cosmo Conception and other places in our literature. Herbert Spencer also rejected the nebular theory because it required a First Cause, which he denied, though unable to form a better hypothesis of the formation of solar systems,—but it is accomplished through the activity of a Great Spirit, which we may call God or by any other name we choose. As above, so below, says the ...

In this relation, he should like to explain the modern idea of the possible method of construction of our own earth. He then set forth the nebular hypothesis that at some long past time our sun and all his planets existed but as a volume of gas, which in contracting and cooling formed a hot volume of rotating liquid, and that as this further ...

... That is the classic joke of the place. Years ago Edison expressed his contempt for the man who watched the clock, and now every Christmas his office family take up a collection and buy him a clock, and present it with great ceremony. He replies in a speech on the nebular hypothesis and all are very happy. One year the present assumed the form of an Ingersoll Dollar Watch, which the Wizard showed to me with great pride.

While the doctrine of Evolution is more or less illustrated in each of these papers, the variety of subjects discussed must touch at some point the taste and pursuit of any reader.

The astronomer explains, or tries to explain, how this evolution took place, by an appeal to the physical processes that have been worked out in the laboratory, processes ...

... Hume, Berkeley, Kant, Hegel, have all been utterly sterile, so far as shedding any light on the details of nature goes, and I can think of no invention or discovery that can be directly traced to anything in their peculiar thought, for neither with Berkeley's tar-water nor with Kant's nebular hypothesis had their respective philosophic tenets anything to do.

We accept the theory of gravitation because it explains all the facts we know, and bears all the tests that we can put it to.

Some inquirers—arguing from the 'nebular theory,' which assumes the formation of the several planets, one after another, from nebulous matter—have supposed the zodiacal light to be a remnant of that matter yet unconcentrated.

We had before us in the sun and planets obviously not a haphazard aggregation of bodies, but a system resting upon a multitude of relations pointing to a common physical cause.
