Describe three pieces of evidence that support the big bang theory

Explanation :

According to astronomers, the whole universe is started with a giant explosion called as Big Bang. Big Bang theory shows that the universe is  extended from high density state.

There are some evidence for big bang as :

(1) There are some red shifts of different galaxies which means that the universe is expanding.  

(2) Due to the expanding of universe, some of the new elements are created like hydrogen, deuterium etc.

(3) Microwaves are detected by orbiting detectors.

All this parameters shows that big bang theory was correct.

Three evidences to prove the big bang theory are:

The big bang theory is an an explanation put forward by scientists know as astronomers to explain how the universe began.

The big bang theory states that the universe began as just a single point, then expanded and stretched to grow as large as it is presently. It also states that the universe is still stretching.

The evidence for big bang theory includes:

Therefore, the evidences above are proof of the big bang theory.
