53 million light-years away from our planet, the black Hole described by scientists as 'monster' was published. For the first time in history, scientists noted that a black hole was photographed, and that their data strongly supports Einstein's theory of relativity.
This black hole in the galaxy of M87 is 40 billion kilometers in diameter and 3 million times the size of the world. 8 observation houses worked together. The name of the black hole, called Powehi, comes from a hymn in Hawaii about the creation that has been said since the 18th century. The meaning of this name, which consists of the combination of the words Po and Wehi, means 'Po' is the deep source of eternal creation and 'Wehi', decorated and adorned.
Another striking feature of this research is Katie Bouman, a young female scientist who showed her success with the algorithms she wrote during the photographing process. Bouman stated that she started to prepare the algorithm while she was doing her master's degree at the Massachusetts Institute of Technology and she has been going on for 3 years. Having made a name for herself a long time on social media, Bouman was an example of success for young people and women alike. Appreciated by many institutions and MIT, Bouman is encouraged by most people to take the place they deserve in history.
What is a black hole and what is the meaning of this invention
Black holes have a few known modes of formation. The most known of these is that it is formed by stars. When the inner pressure of the stars cannot overcome their gravitational attraction, the star begins to collapse. In this case the collapse of the star allows the formation of black holes. This idea, in the direction that the huge masses required for the formation of the black hole, will be formed by the stars, supports the fact that other gigantic masses scattered in the universe after the Big bang can form a black hole.
The idea of a black hole was introduced in the 18th century by John Michell and mathematician Pierre - Simon Lapla. After Einstein developed theories of relativity, Karl Schwarzchild worked on what black holes might look like. Dark holes were originally conceived as frozen stars with a speed of escape greater than the speed of light. After Einstein, however, it began to be considered as holes or singularities in the space-time cover.
In Einstein's theory of general relativity, space and time are a whole, and behave like a veil. The mass grips and deforms this cover according to the mass of objects. The gravitational waves are mainly emitted from black holes and from very dense stars that rotate rapidly around itself. Einstein's general theory of relativity is now used to model the universe. Space can be thought of as a landscape with hills, valleys and pits. The regions where the theory is tested are usually places where gravity is extremely strong or weak.
In a survey conducted in 2018, the astronomers recorded the progress of the S2 black hole on 19 May 2018. When S2 crossed the black hole 120 times the distance of the Earth with the Sun, it reached an orbital speed of 8 thousand kilometers per second. This corresponds to 2.7 percent of the speed of light. The results are consistent with the general theory of relativity. Isaac Newton's ideas in this test did not respond. Frank Eisenhauer for this, "Einstein 1, Newton 0" he said.
The data from the Event Horizon Telescope (EHT) revealed a lot of things. Einstein's theory predicted the observations in M87 with absolute certainty and, as it is understood, correctly explained the nature of space, time and gravity.
The measurement of the material velocities around the center of the black hole is consistent with being close to the speed of light. Scientists at EHT found that the M87 black hole was 6.5 billion times of the Sun's mass and 40 billion kilometers in diameter; this is wider than the 200-year orbit of Neptune around the sun. Due to the rapid change in light output, it was very difficult to get the exact image right from the black hole of the Milky Way. Hopefully, more telescopes will be added to the EHT array soon to get clearer images of these fascinating objects.
