Question

Write about Big Bang Theory ​​

Answer 1

$\huge\bold{\displaystyle \rm\red{Answer}}$

The big bang is how astronomers explain the way the universe began. It 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 (and it could still be stretching).

Answer 2

Explanation:

The Big Bang is a theory describing the expansion of our Universe from a point of origin roughly 13.8 billion years ago.

This hypothetical starting point of everything was an infinite concentration of energy referred to as a singularity. If you find this hard to picture, don't worry. You're not alone. Physical laws don't deal well with infinite numbers, meaning concepts such as space, time, and a bunch of different forces don't mean a great deal in this tiny 'egg' from which the Universe hatched.

For the first 10^-43 seconds of expansion, this density of energy was so extreme physics can't yet provide a clear description of what was happening.

Roughly 10^-35 seconds after the Big Bang the expansion 'jumped', causing the Universe to grow in size by a factor of roughly 10^50 in a virtual instant. This 'inflation' period helps explain why the Universe's background radiation looks as smooth as it does..
