About Space #2 (Black Hole)
Now it's the time to do!
Back in 1784, John Michelle an astronomer pioneer for his time had the idea of a body with so much mass that even light could not penetrate it. In one publication, he presented the calculations that this body could have a density as the Sun. Essentially, his conclusion was that when the diameter of a star exceeded the Sun 500 times this body could be created!
Other scholars of the time were thrilled with such an idea, but over time the enthusiasm began to lose as it could not be understood that such bodies could not be seen by the human.
What is a Black Hole
The black hole is not a body but part of the time! Inside, gravity is so great that even the light itself can not come out. This is because the material has been compressed so much in a small space. This can happen when a star dies.
People can not see the black holes because the light can not penetrate it, they are essentially invisible. The only way to become intrigued and visible to humans is through the use of special telescopes. The research is done in nearby stars that act differently when you are near a black hole.
How the black holes were created
The basic theory is that black holes were created from the beginning of the universe. When a star dies, create a Super Nova and release a part of it in space. Scientists believe that black holes are getting bigger over time.
Εtymology
The term black hole was introduced by American astronomer and physicist John Wheeler, a scholar of general relativity theory when he first used it in a 1967 speech at NASA's Goddard Institute for Space Studies Institute.
Synopsis
The black hole is not a body but part of the time! John Michelle had this idea that in 1784. Several scientists were excited about his idea, but it was sadly not long.
The brute attraction inside a black hole is so great that even the light can not escape.
After a star's death, it is the result of a Super Nova explosion with the creation of a black hole.
The term black hole was told by John Wheeler in 1967.

Interesting, astronomy is one of my passions ;)

A black hole is called a certain area of space in the Universe. To allocate it as a separate star or planet because it is not solid and not gaseous body. Not having a basic understanding of what space-time and how these dimensions can be modified, one cannot understand what is inside a black hole. The fact that this area is not only spatial unit. Is an object that distorts as three known dimensions (length, width and height), and the timeline. Scientists believe that in the area of the horizon (the so-called area surrounding the hole) takes on a spatial meaning, and can move both forward and backward.
I think there a good possibility that black holes exist as a warp in the fabric of time. The speed and intensity of a black hole prevents light from escaping. Anything that can stifle the velocity of light could certainly augment the space time continuum— though quite honestly I don’t necessarily think that the “space time continuum” has the correct implications.
