Even in 1795 Pierre-Simon Laplace predicted the existence of such a huge star with a density and weight that are posed by gravity does not allow passing by the sun's rays reach the earth's surface.However, the astronomical term "black hole" came into use only in 1968 thanks to Wheeler, but until that time used the name "frozen star" or "collapsar."
Black holes - these are regions of space and time in which the action of the gravitational field of such enormous power that no single object (even a ray of light) can not escape from there.
How does a black hole
evolution of stars according to their mass is different.Astronomers believe that the star-black hole is formed as a result of the collapse of very massive stars.Eventually she takes burning the hydrogen, then helium, and then comes the moment of "x" when the severity of the surface layers can no longer be balanced by internal pressure and begins the process of strong compression of the masses.If the mass of the star is from 1.2 to 2, 5 solar masses, there will be a massive explosion.During a disaster most of the star is thrown out, and the luminosity of the star increases in the hundreds of millions of times.
This outbreak is very rare, at least in our galaxy that happens about once every hundred years.There is a new and very bright star, it is called "supernova."However, if, after such an explosion mass of matter still more than 2.5 solar, as a result of powerful gravitational force compresses the stars to tiny sizes.After the end of thermonuclear processes the star can no longer be in a state of stability - it is fully compressed, and the cosmic zoo adds another inaccessible eyes black hole.This phenomenon is on the minds of many scientists.
black hole - a time machine?
Many scientists are still scratching their heads over whether or not you can use a black hole for time travel.No one knows what lies beyond this cosmic crater.In 1935, Einstein and Rouzenom has been hypothesized that a small incision in a black hole may be connected to another section of another black hole, thereby forming a narrow tunnel through space and time.
On the basis of this theory, astrophysicist Kip Thorne has invented an algorithm that using a rigorous mathematical formula describes the working principle and the physics of the time machine.However, for the construction of a temporary portal of modern technological level, alas, is not enough.
At the same time authoritative British cosmologist Stephen Hawking said that the object caught in the black hole does not disappear completely - the energy of his weight back into the universe in the form of information.In its time, the original theory of black holes S. Hawking became a real breakthrough in the field of astrophysics.Now, according to a new theory, black holes obey the laws of quantum physics.The new theory proposed by S. Hawking, making it impossible to use black holes to travel time, or movements in space.
Will we see a time machine Kip Thorne and have to put up with the theory of Stephen Hawking?As they say, time will tell.In the meantime, we can only speculate and hope for the new research scientists.
