['the birth of our solar system began as dust and gases (nebula) started to gravitationally collapse.', 'the nebula contracted into a rotating disk that was heated by the conversion of gravitational energy into thermal energy.']

4.6 billion years ago, the solar system was a cloud of dust and gas. This nebula is made up of dust and gas, mostly hydrogen and helium, with a small percentage of heavier atoms. These heavier atoms had been formed earlier in the history of the Universe when other stars aged and died.

The earliest and most direct observational evidence of the validity of the theory are the expansion of the universe according to Hubble's law (as indicated by the redshifts of galaxies), discovery and measurement of the cosmic microwave background and the relative abundances of light elements produced by BBN.

Corresponding, to this theory, planets what we call know were formed within the disk. Whereas, in protoplanet Hypothesis we get to know the present solar system and universe working. Though having many things in common with nebular hypothesis this hypothesis has modern implement of states of matter and fluid.

Elements are subdivided into several categories based on where they originated from: The Big Bang, Cosmic Rays, Large Stars, Small Stars, Supernovae, and Man-Made labs.

The planets in our Solar System are believed to have formed from the same spinning disc of dust that formed the Sun. This disc, called the solar nebula, was composed mainly of hydrogen and helium, but also had other elements in smaller proportions.

The various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over from the Sun's formation. The currently accepted method by which the planets formed is accretion, in which the planets began as dust grains in orbit around the central protostar.

The other objects, that lie within the Milky Way are now the only objects called nebulae (singular: nebula). There are also many different types of nebulae, including the remnants of exploded stars, vast clouds of gas and dust, and star nurseries where new stars are forming out of clouds of gas and dust.
