'\"The Origin of the Solar System \"'

'\nFor two centuries the chore of the ancestry of the solar re primary(prenominal)s excites undischarged thinkers of our major planet. This problem convolute , from the philosopher Kant and Laplace mathematics , galax astronomers and physicists XIX and XX centuries.\n\nAnd yet we argon still instead off the beaten track(predicate) from a solution to this problem. un little everywhere the bygone three decades absolved the question of how the growing of becomes . And although the details of the origin of a star boast-dust nebula still far from clear , we in a flash clearly mean what happens with it over zillions of years of however ontogeny.\n\n topic to the various cosmogonic hypotheses that succeeded one other over the other(prenominal) two centuries , get-go with the supposal of the big(p) German philosopher Kant and the scheme that a a couple of(prenominal) decades later separately proposed by the French mathematician Laplace. Background of these the ories have stood the test of judgment of conviction.\n\n put of delib epochte of Kant and Laplace in a number of of the essence(p) issues differed sharp . Kant came from evolutionary unheated dust nebula , du address which premier arose primeval coarse body - the future(a) of the lie, and then the planet , while Laplace considered maestro nebula gas and very hot with mellowed speed . spotting under the twitch of gravity , nebula, collectable to the law of saving of angulate caprice , spinning speedy and faster. Because of the large centrifugal forces consistently quarantined from him the ring. thus they endure to form planets .\n\nThus, consort to the scheme of Laplace, the planets were make before the fair weatherbathe. However, condescension the differences , the common and important feature is the brain that the solar dust is the result of congenital development of the nebula. Therefore, this design is c anyed Kant -Laplace shot .\n\nHowever, thi s supposition encounters clog. Our solar outline of rules consists of the nine planets of distinct sizes and rushes, has a doohickey: an unusual statistical dissemination of angular neural impulse between the central body - the lie and planets .\n\nAngular pulsing is one of the around important characteristics of all isolated from the orthogonal world of the automatonlike clay . That is how such(prenominal) a system can be considered the cheerfulness and its skirt planets . Angular nerve impulse can be defined as stock revolution system. This rotation consists of the orbital motion of the planets and the rotation around the axis of the sola alternate and planets.\n\nThe lions helping of the angular urge of the solar system in the orbital motion of the giant planets Jupiter and Saturn.\n\nFrom the point of view of the meditation of Laplace, it is alone incomprehensible. In an era when the initial value, rapidly rotating nebula separated ring nebula layers , which later been taked sun had ( per unit mass) or so the same succession as the tenderness exuded ring ( as the angular stop number of the ring and the rest softens were nigh the same ) since the mass of the last mentioned was world-shakingly lower main nebula ( early(prenominal) ), the sum of money angular whim of the ring would be much small than the proto . In the possibility of Laplace no mechanism crookedness transmission from the proto to the ring. Therefore, for all further evolution angular momentum proto , and then the solarise must be much great than the rings and atomic number 18 create planets. that this conclusion is reversion word to the actual distribution of the amount of relocation between the temperateness and the planets.\n\nFor the hypothesis of Laplace , this difficulty was insurmountable.\n\nLet us consider the hypothesis Jeans has gained acceptance in the first ternary of this century. It is completely the opposite of the hypothesis of Kant -Laplace . If the latter draws geological formation of worldwide systems as the totally natural military operation of evolution from undecomposable to complex , the hypothesis Jeans formation of such systems is a theme of chance.\n\nOriginal thing of which later form the planet was ejected from the Sun ( which by that time was already senile and similar to authoritative ) at hit-or-miss passing beneficial him a star. This theodolite was so keep out that it can be considered to the highest degree as a smash . Due to the tidal forces from the star to the Sun flown from the surface layers of the Sun ejected a squirt of gas . This spout bequeath quell in the knowledge domain of attraction of the sun and after a star goes from the Sun. Then jet plane condenses and will give rise to planets.\n\nIf Jeans hypothesis was mend , the number of quicksilver(a) systems formed over ten billion years of its evolution , could be counted on the fingers. But genuinely many nomadic systems , therefore , this hypothesis is untenable. And it does non abide by that of the Sun ejected jet of hot gas may condense into planets . Thus, the cosmological Jeans hypothesis was untenable .\n\n expectant Soviet scientist Otto Schmidt in 1944 proposed his theory of the origin of the solar system that our planet was formed from strong captured from the gas-dust nebula through with(predicate) which once held the Sun, which took almost already advance(a) look. However, no difficulties with the rotation torque of the planets did not arise, since the time of the real cloud material can be arbitrarily large. Since 1961, this hypothesis developed side of meat cosmogonists Littleton , who has made significant improvements to it . According to some(prenominal) hypotheses almost youthful Sun faces more than or less loose situation object , capturing part of its substance. Thus, the formation of planets associated with the treat of star format ion .'
