Shadow matter

I begin with a handful of names that appeared in early lists (9, 10) but seem to have dropped from the recent literature. Some have probably changed names (in the way that shadow matter is now often called mirror matter) others may be indistinguishable for astrophysical purposes from... 

Mirror or shadow matter also belongs to the extra-dimension territory. The particles are just like ours (hadrons, leptons, and all), but can interact with us only gravitationally across a slightly extended fifth dimension of a particular sort of superstring theory. The standard early reference is (71), and a recent one, whose authors would like to use the stuff for supemovae is (72). 

For the purposes of the present book, we have chosen to speak of atomically luminous, material dust, so precious it seems to us. It is the material frame of beings and structured things, of flesh, birds and stars. Let us not yet provoke the incomprehensible darkness as it lies sleeping in its den. Let us leave in shadow this matter which does not speak the language of light.

It is necessary to deprive matter of its qualities in order to draw out its soul. Copper is like a man it has a soul and a body. .. the soul is the most subtile part. .. that is to say, the tinctorial spirit. The body is the ponderable, material, terrestrial thing, endowed with a shadow. After a series of suitable treatments copper becomes without shadow and better than gold. The elements grow and are transmuted, because it is their qualities, not their substances which are contrary." (Stephanus of Alexandria, about 620 A.D.)... 

A commercial blasted surface finish corresponds to Swedish Standard Sa2 third quality. The finish is defined as one from which oil, grease, dirt, rust-scale and foreign matter have been completely removed from the surface, except for slight shadows, streaks or... 

Aridity is of interest in paleoelevation reconstruction for two reasons (1) in extreme aridity cases, the 818Osc values are dominated by evaporation, and realistic estimates of paleoelevation are probably not obtainable, no matter the sampling density, and (2) aridity develops in rain shadows, and thus may provide qualitative evidence of orogenic blockage of moisture. 

This chaos consists of the siccum and humidum. The siccum constitutes the Earth the humidum is the Water. The shadows are the black color, which Philosophers call nigrum, nigro nigrius, (black, blacker than black itself). This is the Philosophical Night, and the palpable shadows. Light in the creation of the world appeared before the sun it is that whiteness of matter, so much desired, which succeeds the black color. Finally the sun appears, of an orange color, the red of which is deepened, little by little to the red of purple this makes the completion of the first work.. 

In its beginning this Water was volatile, as a mist condensation made of it a matter more or less fixed. But whatsoever may have been this Matter, the first principle of things, it was created in shadows too thick for the human mind to see clearly. Only the Author of Nature knows it, and in vain would theologians and philosophers wish to determine what it was yet, it is very probable that this dark abyss, this chaos, was an aqueous, or humid, matter, since it would be more easily rarefied and condensed, and consequently more suitable, because of these qualities, for the construction of the heaven and earth. 

The body is by itself a principle of death, analogous to that formless, cold and dark mass, from which God formed the World. It represents shadows. The mind is derived from and participates in this matter, animated by the spirit of God, which in the beginning moved upon the waters, and which by its diffused light, infused into the mass that heat, producer of movement and life in all nature, and that fertilizing virtue, principle of generation, which furnishes to each individual the means of multiplying its species. 

But the Innate Fire is very different from Moisture. It partakes of the spirituality of Light, and the Humid Radical is of a nature midway between the extremely subtle and spiritual matter of Light, and gross, elementary, corporeal matter. It partakes of the nature of both, and connects these two extremes. It is the seal of the visible and palpable treaty of light and shadows the point of union and of commerce between the Heavens and the Earth. 

There sets in a divergence between the existence of metal as coin and its existence as a piece of gold or silver. The coin becomes a shadow , increasingly ideal , its golden or silver substance being reduced to a mere pseudoexistence , which continues to perform the function of a legal coin. This sets it apart, as money, from any other matter involved in a chemical reaction. 

What is aura, actually A strange weave of space and time the unique appearance or semblance of distance, no matter how close it may be. While at rest on a summer s noon, to trace a range of mountains on the horizon, or a branch that throws its shadow on the observer, until the moment or the hour becomes part of their appearance - this is what it means to breathe the aura of those mountains, that branch.35...
