Einstein theorized about the general principle of relativity in 1905. Today, in 2020, nearly 115 years after his publication, he stands corrected. But no, he does not stand correct because he was correct. The phenomenon that proves his theory is not a lab set up. It is a natural phenomenon of a revolving star in space.
The recent study, published in the journal, Astronomy and Astrophysics, shows the recent star observation using the European Southern Observatory telescope near the Atacama Desert, Chile. The star has an unusual rosette orbit around it. Newton’s theory of gravitation proves a star has an ellipse orbit. But Einstein’s theory of general relativity shows a rosette orbit around the star.
Einstein’s theory of general relativity predicts that bound orbits of one object close around another. But in Newton’s theory of gravitation, the orbit goes forward with a partial rounded pattern. Reinhard Genzel, Director of the Max Planck Institute for Extraterrestrial Physics, leads the program that arrives at this conclusion.
ESO's Very Large Telescope has observed for the first time a star dancing around the supermassive black hole at the centre of the Milky Way, as predicted by Einstein’s theory of general relativity.

The special effects of Star S2
This effect of rosette orbit shows in the star S2, but it is not the only one. The famous effect was first visible in the orbit of Mars around 100 years ago, the first hardwired evidence to prove Einstein’s theory. Now, the same pattern occurs in a star revolving around a singularity, Sagittarius A* at the center of the Milky Way Galaxy.
This not only proves the theory of relativity but also does it show Sagittarius A* is a supermassive black hole. Its mass is 4 million times that of the Sun. This black hole lies at the very center of our galaxy. Dense and heavy stars seldom go around the black hole. But the S2 revolves around it at a distance of only 20 billion kilometers.
This phenomenon of the rosette orbit of the star, finally proves Einstein was right all along. However, it does raise some questions about Newtonian Gravity.
