Posted on the siteThe confession"The Australian, a report that sheds light on the history of modern science with black holes in space, and how to discover and develop equations that explain them so that we can understand.
The site, in its report translated by "ArabThe Ligurian Meteorological Observatory in the United States, known as Lego, announced at the end of the current year that it has detected the largest and most intense spatio-temporal wave source resulting from the collision of the 'a group of black holes in deep space.
In 2015, scientists were able to observe these invisible astronomical objects, which can only be detected by their appeal.
The history of these mysterious objects dates back to the eighteenth century and was the decisive stage in this region during the Second World War.
According to the site, John Michel and Pierre Simon Laplace, philosopher of the philosophical study of nature and the cosmopolitan physical space, have for the first time approached the concept of the body that captures light and becomes invisible in the 18th century.
They relied on Newton's gravitational laws to calculate the light particle velocity of an object and assumed that there were stars so dense that light could not escape. . Michelle was then called "black stars".
The site adds that the credit is due to the theory of general relativity created by Albert Einstein in 1915, used by the German physicist and astronomer Carl Schwarzschild a year after its creation to find a solution to this physical problem.

He also predicted the presence of a critical body environment that light can not cross, called Schwarzschild radius.
The scientists said that scientists could refute this theory only in 1933, when George Lemter had pointed out that the impenetrability of the body was only an illusion for a remote observer.
Using the famous illustration "Alice and Bob", the physicist was assuming that if Bob remained motionless while Alice was jumping into the black hole, he would see the image of Alice slowly slow down to # 39 it becomes completely rigid before reaching the Schwarzschild radius.
Despite the importance of this theory, there were no bodies of this size at the time, nor any object resembling a black hole, so no one thought there was something similar to black stars that Michele supposed.
In fact, no one dared seriously study this hypothesis before the outbreak of the Second World War.
The publication of the first scientific article on black holes coincided with the outbreak of the Second World War.
The article published by American physicists Robert Oppenheimer and Hartland Snyder, entitled "Continuous Gravity Shrinkage", is an important point in the history of black holes. These two worlds predicted the continuous contraction of the star under the influence of its gravitational field. On a strong pulling force, even the light can not penetrate.
It was the first version of the modern concept of the black hole, which became known as a huge cosmic body that can only be detected by its appeal.
The second world war played a crucial role in the development of this idea: the US government invested in research on nuclear bombs.
Oppenheimer later became director of the Manhattan Project, a research center that worked on the development of nuclear weapons during the Second World War.

This period was marked by a huge race for investment in groundbreaking research in the field of nuclear physics and the development of new technologies.
Physicists have devoted their efforts, in all their specialties, to conducting such research, leading to neglecting the fields of cosmology and astrophysics, including the Oppenheimer research paper.
The site indicated that at the end of the war, research on the study of the universe had been renewed, the theory of general relativity having returned after being underestimated in the past. The war has changed the way physics is treated.
In the end, scientists have again focused on important scientific areas, such as cosmology and general relativity. This was essential to accept and understand the idea of black holes.
The site said nuclear physicist John Wheeler, owner of the title "Black Hole", was working on the theory of general relativity and was analyzing Oppenheimer's findings again.
Although skeptical at first, the influence of relativism and new developments in computer simulation and radio technology, developed during the war, made him one of the greatest fans of what Oppenheimer had predicted on the day of the outbreak of the war. in September 1939.
Since then, theories have been developed and new properties and types of black holes have been discovered, culminating in research in 2015.
One way to measure the gravitational waves generated in the black hole binary system is the first tangible evidence of the existence of black holes in space.
