<u>Answer:</u>
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.
<u>Explanation:
</u>
- 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.
