It’s been more than a century since Albert Einstein published his theory of relativity. And while new research shows that it remains intact, they also say new questions have arisen.

A comprehensive test identified a relativistic redshift from light emitted from a star circling the Sagittarius A* black hole in the middle of the Milky Way, according to a study published in Science.

“Einstein’s right, at least for now,” Andrea Ghez, who runs the Galactic Center Group at UCLA and study co-lead author, said in a news release. “We can absolutely rule out Newton’s law of gravity. Our observations are consistent with Einstein’s theory of general relativity. However, his theory is definitely showing vulnerability. 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.”

Einstein’s theory of general relativity contends force comes from the arc of time and space. It also states the sun and Earth alter that equation.
