It is more likely that a black hole is described as a product of a dying star, or as it may be called "star dust"; one of the most dangerous objects is black holes, as they can be shown as massive cosmic vacuum cleaners. What makes them dangerous is that they have a gravitational force that is so strong that even light passes through it. These former stars or star dust have been the concern of many scientists, so with special telescopes, they observe them and their surroundings.
There are three types of Black Holes: stellar, supermassive, and intermediate-mass. The smallest is the stellar type; it is primarily created by a supernova, a star's super-powerful and luminous explosion. Everything around our galaxy are stellar black holes; the most distant one ever observed is around 13.1 billion light-years from Earth, so it can't do any harm to us. Typically, each has a mass of about three to ten solar masses. A solar mass is a standard unit used in astronomy, defined as our Sun's mass, and equals about 2 to 1030 kg.
In the center of most galaxies, including our Milky Way, the supermassive form, on the other hand, is often found. This form is colossally heavy, and has a mass range of more than millions of solar masses, even billions. Because of their centralized existence in the galaxies, scientists say they are extremely large. When the galaxies merge, this unique form of black holes appears to develop into heavier ones, making them the most dangerous form of black holes.
The third form is the Black Hole (IMBH) intermediate mass, which is estimated to have a mass of between one hundred and one thousand solar masses. It is believed that it could be formed by a single black hole devouring so many objects, or even merging with another black hole; leaving great problems for scientists who have no answers so far. This type can not be from just a single star dust.
Some experiments were performed to illustrate what would happen if, at some stage in its history, the Sun became a black hole. Those hypothetical studies suggested that the World would plunge into complete darkness if the Sun were to become a black hole, and everything would freeze immediately.
The Sun would never turn into a black hole, however, because it is said to have less mass to turn into one than required. As the Sun reaches its end and runs out of its fuel, external layers are immediately thrown off, turning into a glowing gas ring known as a planetary nebula. There will only be a white dwarf star after reaching this point, which is a relatively small star.
Black holes follow the laws of gravity, which the great scientist Isaac Newton first brought to the universe. There is a force, as described in his rule, that attracts all bodies, making them move in calculated directions and measuring velocities depending on the mass of those bodies.
That being said, black holes can't just wander through outer space, or the universe swallowing planets in their path. It has to be so close to the solar system in order for a black hole to impact Earth, which seldom occurs. And if our Sun were to be replaced by a black hole of the same mass, the Planet would be fully in its natural position, since the black hole would hold the same gravity as the Sun.
As far and remote items of interest, black holes can be thought of; nothing to think about here and now. Yet, when groups of scientists researching black holes manage to create one for an experiment, it may be a greater problem than we thought! People believe that the end of our planet could be brought on by this.
Researchers suggest that it's very fun to research the mystery of those amazing black holes, and it will certainly lead to new findings that could be of great benefit to us. Some of the famous physicist Stephen Hawking's claims led scientists to believe that those tiny black holes can only exist for a tiny bit of time until they disappear permanently. They would theoretically vanish instantly, but what if they did not? What if they were able to continue for a lot longer? Should we then be doomed?
Of course not; those black holes are traveling so rapidly that they are going out into outer space. Some of them would travel slower than others, which is far from happening; because of their gravity, they would be stuck on Earth, but would not be a danger to humans at all, since they would only consume a tiny amount of matter from Earth.
Scientists have not managed to create a black hole until now; but, as curiosity is the mother of science, in the near future we will be hearing of some active experiments. It would be something that could be a great help to develop and explain those ideas.
