Why the night looks black. Have you thought of anyone? No, there is a reason for the dark sky and space.
Many people have asked about it, but in 1823 a scientist named heinrich olbers also thought more about why. Two types of cosmology existed at that time. One is the Big Bang and the other is the default theory. In the second, the universe is constant. The universe is spread out in infinity. The stars are arranged as one. The stars die and reappear. It was always like that. Everything is safe. Then came the question. Everywhere you look today, the tide of protectionist sentiment is flowing.
So shouldn’t the whole sky or deep space always be illuminated by these stars that fill the whole universe? That’s when the Big Bang came to the rescue. After the Big Bang, space time or the universe is expanding. Light from a distance is then converted to radiation by a phenomenon called redshift , which is a wavelength that is longer than visible light. As we drive, the noise in the rear speaker seems to fade. As a result, we cannot see them. That is why the abyss of space far away is always covered with the cane of darkness. This is an important factor, even if it is found in the dark matter for some other reason. Then remember that the reason why space is dark and dark at night is the phenomenon of space time expansion which expands faster than light in many places. Link below
