The background extragalactic thermal radiation with a temperature of 2.7 K, which is the result of the Big Bang, is called the relic radiation. The relic radiation is isotropic only in the frame of reference associated with the “scattering” galaxies. In the frame of reference associated with the moving Earth, the CMB is anisotropic. Observations of the intensity of the relic radiation make it possible to record the movement of the Earth around the Sun, the movement of the Sun in the Galaxy and the movement of the Galaxy in the direction of the cluster of galaxies in the constellation Virgo.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
