Albert Einstein against Isaac Newton 1-0. For the first time, researchers from the European Southern Observatory (ESO) have found confirmation of the physicist's theory of relativity. Einstein predicts more than 100 years ago what would happen to a star approaching a black hole. As a test object, the ESO team looked at some star in the Milky Way. The black hole is 26,000 light years from Earth and has four million times the mass of our sun, as Frank Eisenhauer of the Max Planck Institute for Extraterrestrial Physics explains. "The star is getting closer to the black hole every 16 years, it is flying incredibly fast, at about three percent of the speed of light, more than 25 million kilometers at the hour." And if Einstein is right, then the clocks on the star slow down and his light waves are stretched, the gravitation of the black hole makes the star more reddish, this effect is called gravitational redshift. "Understanding how gravitation works in the solar system helps to understand the entire universe," says Odele Staub of the Paris Observatory. "The center of our galaxy was our test lab, and for the first time we we could study gravity in this center, with a black hole and a star that surrounds it, and that's the big thing: we saw that the black hole behaves exactly like Einstein said that it can not be explained by Newton's model. While Newton regarded gravitation as a force that distracted bodies from their space-time lines in the seventeenth century, Einstein predicted that a massive body like a black hole would distort the space- Now, the research team hopes to discover phenomena that can not be explained by Einstein's theory of relativity, so maybe they could develop a new explanatory model that describes better the universe.
