![]() Relativistic redshift of the star S0-2 orbiting the Galactic center supermassive black hole. The findings were published in the journal Science. 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. We can absolutely rule out Newton’s law of gravity,” Professor Ghez said. ![]() The team’s results are consistent with general relativity and substantially favor the theory over Newtonian gravity, which cannot account for the observed redshift. Seeing stars go through their complete orbit provides the first opportunity to test fundamental physics using the motions of these stars.” “We asked how gravity behaves near a supermassive black hole and whether Einstein’s theory is telling us the full story. That’s what gives us the entry ticket into the tests of general relativity,” Professor Ghez said. “What’s so special about S0-2 is we have its complete orbit in three dimensions. The team also used spectroscopic and astrometric measurements from 1995-2017, which cover S0-2’s 16-year orbit.

The star moves around the black hole at blistering speeds of more than 16 million mph (25.7 million kmh). Professor Ghez and colleagues analyzed observations of a star called S0-2 as it made its closest approach to Sagittarius A* in 2018. The theory is the best description of how gravity works,” said University of California, Los Angeles Professor Andrea Ghez, co-author of the study. Einstein proposed that objects such as the Sun and the Earth change this geometry. “Einstein’s 1915 theory of general relativity holds that what we perceive as the force of gravity arises from the curvature of space and time. The shifting of planets along their orbit An increase in the wavelength of light from distant galaxies Red objects in space appear a different colour when.

The new research involved detecting relativistic redshift in the light emitted by a star closely orbiting Sagittarius A*, the supermassive black hole at the center of the Milky Way. Image credit: Nicolle Fuller / National Science Foundation.Īlbert Einstein’s theory of general relativity predicts that a star passing close to a supermassive black hole should exhibit an effect known as relativistic redshift. ![]() A star known as S0-2 made its closest approach to Sagittarius A*, the a supermassive black hole at the center of the Milky Way, in 2018. Redshift is a phenomenon that occurs with waves of electromagnetic radiation when they demonstrate the Doppler effect by their source moving away from an observer.
