Answer:
Option (1), (2) and (3)
Explanation:
The big bang explosion was the point from the universe started to exist. Right after this explosion, the Cosmic Microwave Background (CMB) radiations were released in all the directions and are still propagating in space. These CMB radiations are not visible but their presence can be detected. In addition to this, the helium particles were also released due to this explosion.
In the universe, all the matters are distributed equally in all the directions and in a homogeneous manner because the forces that act on it are also uniform. The universe is comprised of the galaxies, planets, matters, energy and innumerable stars. It appears to be a foam-like structure.
Redshift refers to the shifting of the lights towards the red extreme end of the spectrum. This indicates that distant objects such as stars, galaxies are constantly moving further because of the expansion of the universe.
thus, the correct answers supporting the pieces of evidence of the big band theory are options (1), (2) and (3).
