More than 100 years after Albert Einstein published his iconic theory of general relativity, it is beginning to fray at the edges, according to Andrea Ghez, UCLA professor of physics and astronomy. On July 25, 2019, in the most comprehensive test of general relativity near the monstrous black hole at the center of our galaxy, Ghez and her research team report in the journal Science that Einstein’s theory of general relativity holds up.
Ghez’s research team was able to see the co-mingling of space and time near the supermassive black hole. “In Newton’s version of gravity, space and time are separate, and do not co-mingle; under Einstein, they get completely co-mingled near a black hole,” she said.
Keck Observatory Director Hilton Lewis called Ghez “one of our most passionate and tenacious Keck users.” “Her latest groundbreaking research,” he said, “is the culmination of unwavering commitment over the past two decades to unlock the mysteries of the supermassive black hole at the center of our Milky Way galaxy.”
