More than 100 years after Albert Einstein published his emblematic theory of general relativity, it began to show signs of age. Now, after the most extensive general relativity test still close to the monstrous black hole in the center of our galaxy, University of California professor Andrea Gez has announced that Einstein's theory of general relativity is holding up – for now. Professor Gez said: "Einstein is right, at least for now. We can absolutely rule out Newton's law of gravity. "Our observations are consistent with Einstein's theory of general relativity.
"However, his theory definitely shows vulnerability.
"It cannot fully explain gravity inside a black hole, and at some point we will have to go beyond Einstein's theory of a more comprehensive theory of gravity that explains what a black hole is.
German-born theoretical physicist Einstein, along with Max Planck, is considered one of the two pillars of modern physics.
His theory of 1

Scientist have suggested celestial objects as the Sun and Earth change this geometry.
Einstein's theory is the best description of how gravity works, said Professor Gez, who made direct measurements of the phenomenon near superm.
The laws of physics, including gravity, should apply everywhere in the universe, Gez said , who added that her research team is one of only two groups in the world to watch. The star, known as S0-2, orbits a full orbit in three dimensions around a supermassive black hole in the center of the Milky Way.
The full orbit takes 16 years and the mass of the black hole is about four million times larger than that of the sun.
Researchers claim that their work is the most detailed study ever made of a supermassive black hole and Einstein's theory of general relativity.

Spectra, designated by Ghez as the "Arc of Light" by stars, show the intensity of light and provide important information about the star from which light travels.
The spectra also show the composition of the star. These data are combined with measurements that Gez and her team have made over the past 24 years.
Spectra – collected at W.M. The Hawaiian Keck Observatory, using a UCLA spectrograph built by UCLA professor James Larkin, provides a third dimension that reveals the motion of a star with a level of precision not previously achieved.
Professor Larkin's instrument takes light from a star and scatters it, just as raindrops scatter light from the sun to create an arc.
Professor Gez added: "What is so special about S0-2 is whether we have its full orbit in three dimensions.
"This is what gives us a ticket to enter general relativity tests.
"We asked how gravity behaves near a supermassive black hole and whether Einstein's theory tells us the full story.
"Seeing stars go through their full orbit provides the first opportunity to test fundamental physics using the motions of these stars. ”
