Olbers’ paradox

Olbers’ paradox – This paradox was named after the German astronomer Henry Olbers (1758-1840), who was a famous German scientist.
According to the Olbers paradox, if the universe is boundless and eternal, then in any direction on the plane of view of an observer from the Earth there must be a star surface. This means that the entire sky should be brightly lit, and its brightness should be comparable to the brightness of the Sun. At the same time, the phenomenon of the dark night sky remains unexplained.
Based on the solution of the paradox, a cosmological theory of the Big Bang can be found. She has two circumstances that contribute to this.
Since the beginning of the Big Bang, light has not yet managed to penetrate the universe.
At certain temperatures on the surface of stars, they emit maximum energy in the optical range of the electromagnetic radiation spectrum. The dynamic expansion of the universe, which began after the Big Bang, leads to a red shift in the spectral lines of stars. This action leads to the transformation of the brightest part of their visible spectra into the infrared part of it, which is not visible to the eye.
It is likely that the universe has a closed character, i.e. it is not unlimited and the number of stars in each direction is limited.
