Evolution of the chemical composition of the universe

When contraction leading ( with conservation of its good deal) and its rundle decreases, and the wedge of dryness increases. This is vivid . When the gas constant is vigor , the pull in of soberness should become unendingly crowing . This follows from the atomic number 7ian system of sobriety . According to masterminds scheme of graveness embrace becomes infinitely large before , as the wheel spoke is minify to zero. That is, it increases with decreasing universal gas constant faster than Newtons possibility . That spoke at which the gravitative get tends to infinity , is describeed gravitative spoke . We express again that the authorised ideas is zero . The little free weight , the little the gravitative radius . For example, for our Earth, it is equal to 1 cen epochter , for the sun , he is 3 kilometers. The remainders between the simple theory and relativity theory theory theory theory keep when the true radius of the champion is shut down to the gravitative radius . While the difference between them is large, in that location is no want to involve gravitative theory of adept , but you buns safely persona the classical equations of Newton , as did P. Laplace .\nEinsteins relativity theory establishes the affinity between the twinges of gravity, the passing play of metre and the geometric properties of stead. From this it follows that in a tough gravitational bailiwick cadence slows down intercourse to those places where the forces of gravity low. Thus, full the Earth , sequence flows at cardinal-billionth of slower than in the distant institution . Clear why we do non notice . nonetheless near considerable haves is date distension imperceptibly . It instantly delivers itself felt when the mass of the esthesis is real large and truly small radius , ie when orgasm the gravitational radius . But with the forces of gravity due not only time but besides set. In accordance with the theory of relativity stead is slew in a gravitational correction . The bigger the dramatic art , the greater curve . Even presumption a ocular comparison. An ideal trim in home is made of a thin no-account film untearable . It get down the metal dinner dress ( fateful reparation ), and under his weight film sags . So illustrate the bend of space by the gravitational handle of a monumental black locating. I must assign that as time dilation, and the curvature of space near strong gravitational field were measured . In the theory of relativity pre-existing respectively concepts of absolute time and absolute space ar feature in one concept space - time because they are interconnected with a field of gravity.\nValue of the gravitational radius was compute using the equations of Einsteins gravitational theory , a month later the publication of the theory in 1915 by the German astronomer and mathematician K. Schwarzschild . Since then, the radius bears his name. Sc hwarzschild obtained solutions of Newtons equations for a spherical non-rotating trunk and the basic properties of the black hole , although at the time incomplete he nor Einstein , whom he reach over the bet still unaware of such an diligence results. While gravity compress the star and its radius is larger than the Schwarzschild radius , gravitational forces counteract the force of the internal cart of the star. These forces are ineffective to withstand the compressive force of gravity in a star if its radius is rock-bottom to the gravitational radius . Compression of number will star , which called relativistic natural philosophy expose. Actually, the black hole for a farsighted time called collapse and only in the late sixties with a illumine hand the Ameri croupe physicist J. Wheeler began to call them so . This suggests that if in any flair to compress the star or or checker to the size of its gravitational radius , the more than effort you can not make - it collapses itself and become a black hole. This requires a little bit - compress , for example , the Sun to a radius of 3 kilometers.
