WE FINALLY WAITED The first photo of the BLACK HOLE has been published (PHOTO)
The international scientific team presented an incredible scientific discovery in astrophysics – the first photograph of a black hole, which is a feat that will test the pillar of science: the general theory of relativity by Albert Einstein. Black holes are extremely dense celestial entities with gravitational fields that are so powerful that neither light nor matter can escape from them, making them extremely difficult to observe despite their enormous mass.
Press conferences were held in Washington, Brussels, Santiago, Shanghai, Taipei and Tokyo, where this pioneering result of the “Event Horizon Telescope” project (EHT – Event Horizon Telescope) was announced. The conference in Washington is scheduled for 9:00 AM local time, or 3:00 PM local time.
By the way, this project started in 2012 in order to directly observe the immediate surroundings of the black hole with the help of a global network of telescopes. The horizon of the black hole event, ie its boundary, is a point of no return after which everything – stars, planets, gas, dust and all forms of electromagnetic radiation – goes into oblivion.
The project aimed at two supermassive black holes located in the centers of different galaxies. The research will test Einstein’s general theory of relativity from 1915, which explains the laws of gravity and their relation to other natural forces. Einstein’s theory allows the prediction of the size and shape of a black hole. If that prediction turns out to be incorrect, the theory will need to be re-examined.
One of the black holes, Sagittarius A *, is located in the center of our Milky Way galaxy, 6,000 light-years from Earth and has a mass 4 million times that of the Sun. The second black hole, M87, is in the center of the neighboring Virgo A galaxy, with a mass 3.5 billion times larger than the Sun and a distance of 54 million light-years from Earth.
Black holes, which can have different sizes, form when supernovae, very massive stars, explode at the end of their life cycle. The fact that black holes do not allow light to come out makes their observation very difficult.
Scientists will look for a ring of light – distorted matter and light circulating at tremendous speed on the edge of the event horizon, around the area of darkness that represents a real black hole. This is known as the shadow, ie the silhouette of the black hole.
Scientists say that the shape of the shadow, according to Einstein’s general theory of relativity, should be an almost perfect circle, and if it turns out not to be, something is wrong with that theory.
