Recently due to the pandemic, I was watching Youtube videos on Astrophysics.
Blackholes are massive stars that have collapsed towards its end of life. When they collapsed into smaller and smaller size, the gravity of the stars still remain as enormous. There comes a point when the gravity is so greatly concentrated into a small area that light fails to escape, forming blackholes.
However, we know that light can be "bent" or refracted. When light passed through a medium, such as water or glass, the light is refracted. At certain angle when light passes from a denser to a lighter density medium, the light actually bends inward. This phenomenon is called, Total Internal Reflection. Light is not refracted out of the medium
We also know that light can be "bent" when it passed through an object with huge gravitational pull, such as the Sun. Light from distance stars has been observed to be bent by the gravity of the Sun.
Without any evidence or mathematical derivation, I would like to hypothesize that because of the great gravity in a blackhole, the light from the star is being "refracted" internally or inwards, such that no light can be seen from a blackhole. It is not the current belief that light cannot escape from the gravity. But light is being reflected due to gravity, similar to the observation in Total Internal Reflection.
This is just my hypothesis. Blackholes being very far away, I will have challenges in proving such a theory. Perhaps it will take more than a hundred years to determine if it is true. Of course, the hypothesis could be wrong and there are other reasons why light cannot 'escape' in a blackhole.
Hypothesized in August 2020.
