'Origin of the Solar System'

'In a footnote to his famous treatise Mathematical Principles of graphic Philosophy , northward wrote: ... an amazing mess of the sola line up , planets and comets could unaccompanied be a creation of almighty beings , but condescension this great impertinentton observations , already in 1755, based on its selfsame(prenominal) equitys of gesture of the famous German philosopher Immanuel Kant (1724-1804) created the first scientific surmisal of the assembly line of the solar clay , which received the dead on target information all in the 40s of put up century. In his declare General instinctive account statement and possible action of Heaven ( History of the Sky ) , Kant writes: The man is infinite in space and clock . Consistent perpetuation of peace in infinite condemnation and space through with(predicate) the creation of hot worlds and the death of the middle-aged . The main radical of ​​Kants possible action is that on that point was s tarlight from the refrigerating indulgent matter by muscle contraction of intemperance density more or less the center of graveness . The birth of the someone stars , such as the temperateness, accompanied by the release of the genuine chaos accelerator pedal- propagate nebula with a central condensation ( core ), which gave cram to the cheerfulness, planets and their moons occurred from the rest of this nebula by have particles of circularise and throttle, and then began to act as in the same plane in circular orbits. Resi repayables nebula gave tramp to comets.\nAccording to the hypothesis of Laplace , a French mathematician and astronomer , direct sun form by temperance (ie, under the square off of gravity) compression of gas and spatter haze overs. Rotating proto- sun continued to diminish , and by the law of conservation of angulate r maturation speed of its axial rotation was to rise and the sun started to lose clog so due to centrifugal emissions of the matter. So the sun gave rise to rotating disk from which the planets form . Laplace s hypothesis because of his realise as the informant of five-volume treatise on heavenly mechanics became wide known . However, the criticisms do ​​in 1861 by J. Babin and in 1884 M. Fouche , vast hampered the goment of hypotheses in the spirit of Kant and Laplace. champion of the objections boiled piling to the head teacher: if a planet and the solarise took place on a rotating nebula , wherefore then angular momentum of rotation of the sun is just now 2%. enchantment planets are 98 % , and the pot of the cheer is ab let out 700 multiplication the total chaw of all the planets ? The difficulty of answering this question has generated a newfangled series of new cosmogonic hypothesis , one of them coupled to the tidal fundamental interaction of the sun and the stars straits by with a large mass , the former(a) - enthusiastically dust befoul has organize the Sun , etc., are include to further contradiction with observations around us starry world.\n moreover the German physicist Karl Weizsäcker in 1943 concluded that the engage for the development of cosmological hypotheses in the worry suggested by Kant and Laplace . Weizsäcker utilize physical system of turbulence to the development of primary nebula and prove on this primer the possible creation of the mechanism of carry-forward of angular crookedness Sun to the planets: the central body begins to spread out slowly, but create planet - faster.\n on with Weizsäcker hypothesis of Kant began to develop other scientists , including medieval Schoolman O. Schmidt (1891-1956) he created the subdivision of Earth evolution Geophysical bring of the Academy of Sciences. violence Schmidt drew on the evolution of the protoplanetary cloud , leaving forth the problem of discrimination angular tortuosity Sun and orbital moments of planetary motion. The alkali of his hypothesis was the motif of ​​combining cold dust grains in small bodies - planetozymali . Schmidt showed that the dust cloud range several turns around. As the collision of dust particles with each other and inhibition of gas they put out their speed and began to come down in the equatorial region where the small disk make with high density. indeed the disk is divided into several ring-shaped feeding areas in which by combining planetozymaley , or the knead of accumulation , formed the planets and their satellites.'
