Astrophysicists for the first time in history presented an image of a black hole. Rather, its visible boundary – the horizon of events.
The photo was taken from the galaxy M87 in the constellation Virgo, which is 50 million light-years from Earth. On April 10, in honor of the opening presentation, conferences were held in several countries.
Let the photo and muddy, but this is the first in the history of mankind clear evidence of the existence of black holes.
A black hole is an area with enormous gravity. Even objects with the speed of light, that is, maximum in the Universe, cannot leave its limits. The existence of such holes suggested in his time by Albert Einstein. Some equations of the general theory of relativity hypothetically confirmed their behavior and form. The latter coincided with the received photo.
Black holes still remain one of the mysteries of physics. For their study, the project was created "Telescope event horizon." To get a photo, it took to process 500 terabytes of data. It took two years. But scientists still do not fully understand the mechanism of the appearance of black holes and many of their properties, confining themselves in many respects to hypotheses. For example, the hypothesis of "no hair", according to which black holes are characterized by only three parameters (mass, electric charge and angular momentum). All other information is absorbed by the black hole and is not available to the observer.
Black holes are becoming the object of attention of many science fiction writers. For example, some suggest that their gravity will help travel through time. Something similar you could see in the movie Interstellar by Christopher Nolan.Tags: Black, hole, Interstellar, photo, presented, scientists
