Astronomers have found that the black hole of Einstein's superlativity, which we think to be at the center of our galaxy, shows attraction characteristics predicted by the theory of general relativity . Scientific Journal The news published in the magazine Astronomy and Astrophisics was published by the European Southern Observatory (ESO). Astronomers who tracked the position and speed of a star known as S2 set in motion the theory of attraction, as it was imagined by Einstein. Although Newton's mathematical definition of gravitational force has been in effect for 250 years, Einstein has rewritten the concept of gravity by adding space and time a century ago. In most parts of the world where gravity fields were weak, Newton's mathematics and Einstein's views yielded similar results for the motions of galaxies, stars, and planets. However, as the gravitational pull of the galaxy increased, we saw that there were subtle differences between the two points of view. In fact, while working on the vision of gravitational power, Einstein realized that Mercury had significant changes as it rotated around the sun. More than twenty years of astronomical astronomers have been drawing orbits of stars around a supermassif that is not visible at the center of our galactic galaxy. To maintain the movement of the stars, the center of the Milky Way must have a mass four times larger than the mass of the Sun. This mass was concentrated in a small volume. For astronomers, such a monster was a black hole.
THE NEXT STARS
While the existence of a black hole of star movement in the center of the galaxy emerged, astronomers followed the orbits of these stars and found that the Einstein's attraction he was wondering if they could find his signature. Most stars are too far from the black hole to keep track of where their power is weakened. The orbits had to adapt to Newton and Einstein. However, the S2 star has surprisingly had a rather elliptical orbit. This star was about three times larger than Pluto's orbit in the solar system and about 20 billion miles from the black hole every 16 years. It was a very short distance compared to the size of the galaxy. If astronomers correctly followed the S2 star, the difference in the Newton and Einstein attraction theories would be evident in the nearest black hole. Astronomers have used four huge 8-meter telescopes on a mountain in Chile for that. The light from each telescope was combined into a large room by a technique called interferometry. This view gives sharpness to get details at the desired level. A team of astronomers is prepared for May 2018, where the S2 star is closest to the black hole. With small changes in the wavelength, changes in the speed of the S2 star were observed using the Doppler shear technique. As the star approached the black hole, Doppler changes increased and eventually corresponded to Newton's vision. However, when the star approached the black hole, the speed increased more than expected by 200 km / h. The star was slightly blue because Einstein predicted the S2 star at the time of the highest shot while passing in front of the nearest black hole. This extra speed was not due to the actual increase in movement. Another factor came into play when starlight remained in a state of opposition to the increase in firing power. According to Einstein's theory of general relativity, the wavelength of electromagnetic radiation extends as we move away from the field of attraction. This effect called gravitational redshift had been detected Einstein a century ago. The light of the star is spreading longer. It turns red. This change in wavelength was observed when the star S2 approached the black hole and was distant. With this new identification, it is assumed that a new bend has been inscribed in the investigation of black holes. The theory of Einstein's general relativity will be tested more and more precisely. Astronomers say that Einstein's theory of the theory of space and time will remain in force until Einstein's precision in the theory of general relativity leads to deviations up to then
