The formation of the solar system. According to the Big Bang theory, the solar system was formed from a cloud of space dust and gas that was ''squeezed'' by a supernova explosion. As the nebula contracted, it spun increasingly rapidly, leading to frequent collisions between dust grains. Gravity pulled the gas and dust together, forming a solar
The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. [ 1 ] The notion of an expanding universe was first scientifically originated by physicist Alexander Friedmann in 1922 with the mathematical derivation of the Friedmann equations. [ 2 ][ 3 ] 4 [ 5 ]

2 days ago· Big objects collided with bigger objects, forming still bigger objects. Finally some of these objects became big enough to be spheres—these spheres became planets and dwarf planets. Rocky planets, like Earth, formed near the Sun, because icy and gaseous material couldn''t survive close to all that heat. And like that, the solar system as

The Big Bang models offer a comprehensive explanation for a broad range of observed phenomena, including the abundances of the light elements, the CMB, large-scale structure, and Hubble''s law. The models depend on two major assumptions: the universality of physical laws and the cosmological principle.
