Question

The cosmic microwave background radiation, the remnant of the radiation produced in the original Big Bang explosion, appears to us to be not quite uniform in temperature or intensity in all directions—that is, it is not isotropic.

Why is this?
The Earth, as part of the solar system and the Milky Way Galaxy,is moving through this radiation and the Doppler effect producesthis anisotropy.

Answer 1

The Earth, as part of the solar system and the Milky Way Galaxy, is moving through this radiation and the Doppler effect produces this anisotropy.

Explanation:

• The fact that the Earth is moving within a moving galaxy stands as the reason for the occurrence and non-occurrence of many phenomenons.

• The anisotropy experienced in the cosmic microwave radiation that the Earth is subject to is due to this movement of Earth.

• The positions secured by Earth during the course of its movement either block these radiations or make way for them to reach the earth, and hence, the anisotropy is experienced.
