The cosmos, how dark the universe can be, there is light beyond the farthest galaxy, everything we see is the product of stars and events that we know or there is light that is produced by phenomena that are now unknown to us.

The big question, because if it turns out that if we measure the light of the universe and it is less than that calculated in the theory, a theory that implies that the light we see comes from objects and events known as stars and the environment of black holes, if it turns out That in reality there is less light is that something is wrong in how we understand the entire universe and vice versa, if when measuring that light of the universe it turns out that there is more light, the thing becomes even more extraordinary, because it means that there are cosmic phenomena that we still do not know about, but measuring the Real light of the universe from the earth is very complicated.

In 2022, New Horizons made a measurement of that cosmic optical background and the result was that there was much more light than expected, so we would be in the option that there are unknown phenomena that produce light, at that time the alleged culprit was accused. to dark matter, which is the great wild card of modern astronomy, but current research is much more precise, they carefully calibrated the observed light levels and also compared them with the data taken in infrared by the Planck satellite, in the end the The result is that the brightness of the universe coincides with what is expected from the light generated by all the Galaxies that have formed in the universe for more than 12 billion years, therefore, dark matter is innocent and beyond that there is no existence. unknown objects or events that generate light.
