Black Holes
Why is a black hole dark?
Or rather, what happens to the energetic part of the photon, the light wave, when it wants to escape from the black hole at 299,792 kilometers per second?
First of all, we do not know or will know what images can show a black hole inside, since it is a trip without a return ticket. Not even taking a phone could we report what we see inside, because the radio waves would not come out of the hole either.
I remember a suggestive thought that said: «Maybe, we want to see what the inside of a black hole looks like, maybe, we should look around us, because neither in this Universe does matter and light have an exit ticket», a Universe in expansion, which without limits or defined edges, remains closed due to the gravity of all existing matter.
Undoubtedly, black holes are a product of stellar evolution, the laws of gravitation brought to their maximum consequence. According to General Relativity, on the surface of any massive object like a star, time flows more slowly than being very far from it, this is called gravitational dilation of time, the greater the severity, the more it freezes and the time stops.
The black hole never emits any kind of radiation, light or image, it is total darkness. Scientifically, it is said that the wave of light or photon, as it tries to leave the intense gravitational field to cross the critical circumference of the black hole, the wave progressively undergoes a total displacement towards the red end of the spectrum, where the wavelength lengthens to the infinite and the light darkens.
