There are powerful things in the universe, far away from us, which exist for a reason. One of those beings are Black Holes.
We all heard about those strange, terrific, black, absorbing entities, but are they real? Are they what they seem to be?
First thing first, what’s a black hole: When a supergiant stars (O type) dies, they explode into supernovas and then colapse over themselves and turn into a black hole or neutron stars. The density of this one is so dense that nothing can escape its attraction. The Suns that end likewise have between 15 and 90 times the mass of the Sun and they are between 30,000 and 1,000,000 times as luminous as the Sun.
The black holes act like whirepools, they pull everything within their reach such as planets, suns, satellites… and particles such as light. That’s why they cannot be seen, we need High Tech telescopes to detect light diffraction which help us notice that something huge is in the way.
Some theories say that black holes aren’t as we believe them to be. They’re not holes, and they’re different from what we imagine, because we’ve never seen one. But what difference does it make, either a hole or not. The amount of gravity the hole exerts is so powerful that nothing absorbed remains as it is.
Let me explain: there is something called The Event Horizon, whatever crosses that line is doomed to be shattered, exploded, annelid before reaching the entity itself. The object inside the horizon zone is streched to the point that a ball will look like a drop (see sketch #12) nothing comes out of the horizon zone, its fate is sealed.
The light curves arriving at that limit so that the image (light) of a star will become two, in different directions.
These monsters are what keep the expansion of the universe as it is, not too fast, nor too slow (thank God).
There are a few in our Galaxy among which one is at its center, in the constelation of Sagittarius, called Sagittarius A, it’s a supermassive one, probably to keep the Milky Way in shape. There is nothing to worry about; it is way too far to have a direct effect on our solar system.
The bottom line is that, we’re not able to know exactly what these black holes are. Some believe they may be a way to another universe, while others believe they are a way to the future or to the past…
Whatever the answer is, Black Holes are mysteries among mysteries
