yes

Explanation:

yes ..............

Answer 2

Answer :

Not proved , it's a theory .

• There is no evidence of any phenomena prior to the singularity. Detailed measurements of the expansion rate of the universe place the Big bang at around 13.8 billion years ago, which is thus considered the age of the universe.

• After its initial expansion, the universe cooled sufficiently to allow the formation of subatomic particles, and later atoms.

• Giant clouds of these primordial elements mostly hydrogen, with some helium and lithium later coalesced through gravity, forming early stars and galaxies, the descendants of which are visible today.

• Besides these primordial building materials, astronomers observe the gravitational effects of an unknown  dark matters  surrounding galaxies.

• Most of the gravitational potential in the universe seems to be in this form, and the Big Bang theory and various observations indicate that this gravitational potential is not made of baryonic matter, such as normal atoms.

• Measurements of the redshifts of supernovae indicate that the expansion of the universe is accelerating, an observation attributed to dark energy's existence.

• Georges Lemaître first noted in 1927 that an expanding universe could be traced back in time to an originating single point, which he called the "primeval atom". For several decades, the scientific community was divided between supporters of the Big Bang and the rival steady-state model, but a wide range of empirical evidence has strongly favored the Big Bang, which is now universally accepted.

• Edwin Hubble confirmed through analysis of galactic redshifts in 1929 that galaxies are indeed drifting apart; this is important observational evidence for an expanding universe. In 1964, the CMB was discovered, which was crucial evidence in favor of the hot Big Bang model, since that theory predicted a uniform background radiation throughout the universe.
