about big bang theory
Answers
Solution :-
The big bang theory is a scientific theory about what happened at the very beginning of our universe and then how the stars and galaxies came into existence. According to the standard theory, our universe sprang into existence as "singularity" around 13.7 billion years ago. Singularities means a zone where some property is infinite. For example, at the center of a black hole.
Discoveries in Astronomy and Physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. Prior to that moment there was nothing; during and after that moment there was something : our universe. The big bang theory is an effort to explain what happened during and after that moment. Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something a singularity.
After its initial appearance, it apparently inflated (the big bang), expanded and cooled, going from very, very small and very, very hot, to the size and temperature of our current universe.

The Big Bang is how astronomers explain the way universe began . It is the idea that the universe started as just a single point , then expanded and stretched to grow as large as it is now . ( it could be still stretching )
In 1927 , A astronomer named Georges Lemaitre had had a big idea . He said that a very long time ago , the universe started as just a single point . he said the universe stretched and expanded to get as big as it is now , and that it could keep on stretching .
