The light produced by the universe
The light produced by the universe
Starlight is something wonderful, think for a moment if we see them it is because light particles or photons reach our eyes that came out of those stars a long time ago, for example, the most distant star visible to the naked eye, although this is simple View is a bit relative, since it depends on your visual ability and how clean the sky is with respect to light pollution in that place, but experts estimate that that star, the most distant that could be seen with the naked eye, is Nu Cefei is located about 6,750 light years away.

It can be said that we literally touch particles from Nu Cefei and also from Andromeda and all the stars that we see, we touch them with our eyes and interpret them with our mind, looking at the universe is something wonderful, yes or no, but here we come to a question that astronomers have been asking for a long time, all the light we capture comes from things we know, things like stars, galaxies and black hole environments or there are lights that come from currently unknown phenomena or objects.
The paradox says in a simplified way that, if the Universe is supposed to be infinite and therefore with an infinite number of stars, any direction in the sky in which we look should end in a star, no matter how far away it is, which means that the entire The sky would have to be as bright as the sun itself, both day and night, luckily this is not the case since in addition to light we would receive a lot of heat.
