Astronomy


Astronomy is a natural science that deals with the study of celestial objects (such as stars, planets, comets, nebulae, star clusters and galaxies) and phenomena that originate outside the Earth's atmosphere (such as the cosmic background radiation). It is concerned with the evolution, physics, chemistry, meteorology, and motion of celestial objects, as well as the formation and development of the universe.

Astronomy is one of the oldest sciences. Prehistoric cultures left behind astronomical artifacts such as the Egyptian monuments, Nubian monuments and Stonehenge, and early civilizations such as the Babylonians, Greeks, Chinese, Indians, and Maya performed methodical observations of the night sky. However, the invention of the telescope was required before astronomy was able to develop into a modern science. Historically, astronomy has included disciplines as diverse as astrometry, celestial navigation, observational astronomy, the making of calendars, and even astrology, but professional astronomy is nowadays often considered to be synonymous with astrophysics.

The law of gravitation is the law of Music as well as of Astronomy. The cycles of the distances, that is the intervals, in Music correspond to the cycles of the periods in Astronomy. In Astronomy the distances and quantities of matter are primary, and determine the periods; in Music the periods and quantities are primary, and determine the distances or intervals. In Astronomy the distances are commensurable; in Music the periods are commensurable. In Astronomy the periods are incommensurable; in Music the distances or intervals are incommensurable. In Astronomy, because the simplicity is not in the periods, the conjunctions are very few at one time; in Music, because the simplicity is in the periods, the conjunctions are very many at one time. And herein lies in the one case the harmony and permanence of the solar system, and in the other case the harmony and beauty of the musical system. The periods and distances in Astronomy and Music are inversely related. [Scientific Basis and Build of Music, page 30]

The mathematical scales, if followed out regardless of other laws which rule in music, would read like a chapter in Astronomy. They would lead us on like the cycles of the moon, for example. In 19 years we have 235 moons; but the moon by that time is an hour and a-half fast. In 16 such cycles, or about 300 years, the moon is about a day fast; this, of course, is speaking roughly. This is the way seemingly through all the astronomical realm of creation. And had we only the mathematical ratios used in generating the notes of the scale as the sole law of music, we should be led off in the same way. And were we to follow up into the inaudible region of vibrations, we should possibly find ourselves where light, and heat, and chemical elective motions and electric currents are playing their unheard harmonies; or into the seemingly still region of solid substances, where an almost infinite tremor of vibrations is balancing the ultimate elements of the world. Music in this case would seem like some passing meteor coming in from among the silent oscillations of the planetary bodies of the solar system, and flashing past with its charming sound effects, and leaving us again to pass into the higher silence of those subtle vibrations to which we have referred, having no infolding upon itself, no systematic limit, no horizon. But music is not such a passing thing. Between the high silence of these intense vibrations, and the low silence of oscillating pendulums and revolving planets, God has constituted an audible sphere of vibrations, in which is placed a definite limit of systematic sounds; seven octaves are carried like a measuring line round twelve fifths; and motion and rest unite in placing a horizon for the musical world, and music comes [Scientific Basis and Build of Music, page 39]

"There are two distinct laws which rule in astronomy - viz., masses and distances; and there are two distinct laws which rule in music - affinities and proximities. The notes produced by simple ratios as 1:2, 2:3, 3:4, etc., are attracted to each other by the law of affinity; notes which are beside each other in the octave scale and have moderately complex ratios as 9:10 and 15:16, are attracted to each other by their proximities. F and C, and C and G, and G and D are related to each other by affinity. C is related to the fifth below and the fifth above; G is related to the fifth above and the fifth below. F and C, C and G, and G and D are never nearer to each other than a fifth or a fourth, and in either case they [Scientific Basis and Build of Music, page 95]


Paracelsus
"Astronomy contains in itself seven faculties or religions; he who does not know them all is unworthy to be called an astronomer. Let each man remain in that religion or faculty wherein he occupies himself; let the astologer deal with astrology; he who treats of the religion of magic, let him remain exclusively a magus; he who is concerned with divination, let him remain a diviner; he who regards nigromancy, a nigromantic; he who studies signatures, a signator; he who is devoted to the uncertain arts, an incertus; he who investigates matter, a physicist. Let not the astronomer deny that magic is astronomy, nor yet refuse the name to divination, nigromancy, and the rest. All these things are comprehended under astronomy as much as is astrology itself. They are natural and essential sciences of the stars, and he who is acquainted with them all, he is worthy to be called an astronomer. But albeit these sciences are sisters, they have heretofore been ignorant of their relationship, which it is important to recognise, so that one may not be despised by the other." [Paracelsus. Hermetic Astronomy.]
