An international team of scientists, observing a star in the Milky Way, confirmed for the first time what Einstein had predicted for the movement of a star passing near a giant black hole
Einstein's theory of general relativity predicts Stars are extended to longer wavelengths by the gravitational field of a black hole, and the star will be red at red, an effect known as polar red drift. We were able to directly test the theory of relativity
"In Einstein's time, we could not think or even dream of what we see today."
A team of scientists from the Southern Observatory began to observe the central area in the Milky Way using a massive telescope to monitor the movement of stars near the giant black hole there 26 years.
The black hole is 26,000 light-years from Earth and has a mass of four million times the mass of the Sun. Since the star has completed its orbit in 16 years, scientists have realized that it would return to the black hole in 2018.
For 20 years, the accuracy of the devices used has improved . In May 2018, they were able to carry out microscopic measurements in collaboration with scientists.
This shows that the speed of the orbital star exceeds 25 million km / h at the approach of the black hole.
The orbital wavelength of the star is extended as it seeks to escape the gravitational claws of the black hole. The giant, who changed his form from blue to red.
