P. Colli Franzone,L. F. Pavarino,G. Savaréide, are then turned off. There is no heat and pressure being generated inside such a star, so the internal support has been removed and it begins its ultimate contraction. The demise of such a star results in the simultaneous creation of a new star from its collapsing core, with a final resting state that depends on the star’s mass.作者: 傻瓜 時(shí)間: 2025-3-22 14:47

Origin, Evolution, and Destiny of the Observable Universe,Regardless of the direction in which we look out into space, almost all of the distant galaxies are flying apart, dispersing and moving away at speeds that increase with their distance, as if they had been ejected by a cosmic bomb.
