Abstract

The present article has systematically solved the problem of galaxy formation and some significant cosmological puzzles. First a mistake with Einstein’s equation of gravitational field is corrected, next space-time is proved to be infinite, cosmic expansion and contraction are proved to be in circles, the singular point of big bang is eliminated naturally, celestial bodies and galaxies are proved growing up with cosmic expansion, for example Earth’s mass and radius at present increase 1.2 trillion tons and 0.45 mm respectively in a year, in response to which geostationary satellites rise 2.7 mm.
