SOLAR SYSTEM

Detailed explanation-1: -The most popular theory of our universe’s origin centers on a cosmic cataclysm unmatched in all of history-the big bang. The best-supported theory of our universe’s origin centers on an event known as the big bang.

Detailed explanation-2: -Big Bang Theory is the idea that the universe began as just a single point, then expanded and stretched to grow as large as it is right now. It is the simplest explanation for the origin of the universe which scientists claim is still expanding.

Detailed explanation-3: -The big bang theory is the consensus cosmological framework for explaining the origin, properties, and evolution of the universe. According to this theory, the universe began almost 14 billion years ago in an extremely hot and dense state, from which it has cooled and expanded since.

Detailed explanation-4: -This startling idea first appeared in scientific form in 1931, in a paper by Georges Lemaître, a Belgian cosmologist and Catholic priest. The theory, accepted by nearly all astronomers today, was a radical departure from scientific orthodoxy in the 1930s.

Detailed explanation-5: -The universe began, scientists believe, with every speck of its energy jammed into a very tiny point. This extremely dense point exploded with unimaginable force, creating matter and propelling it outward to make the billions of galaxies of our vast universe. Astrophysicists dubbed this titanic explosion the Big Bang.
