![]() ![]() ![]() "Making a measurement of such fundamental importance has required years of patient observing, enabled by state-of-the-art technology," said Richard Green, director of NSF's Division of Astronomical Sciences, which funded the research. Keck Observatory, as well as the Subaru Telescope and the NSF-supported Gemini Telescope to conduct the observations. It cannot fully explain gravity inside a black hole, and at some point we will need to move beyond Einstein's theory to a more comprehensive theory of gravity that explains what a black hole is." However, his theory is definitely showing vulnerability. "Our observations are consistent with Einstein's theory of general relativity. "Einstein's right, at least for now," said Ghez. After 24 years of observations that measured the star's precise positions and the wavelengths of its light, astronomers have shown Einstein's predictions, once again, hold up.Īn international team of astronomers co-led by UCLA professor Andrea Ghez published the results of the study in Science. The star S0-2 is a perfect test candidate, as it orbits the supermassive black hole at the heart of our Milky Way galaxy once every 16 years. ![]() Instead, astronomers turn their attention to where the action happens, such as stars orbiting black holes. ![]() More than 100 years ago, Albert Einstein predicted that light is deflected by extremely massive objects, but there is no way to test such powerful effects on Earth. ![]()
