Milky Way Center’s Light from 26,000 Years Ago –“Reconfirms Einstein’s General Relativity”

“We’re so excited, and have been preparing for years to make these measurements,” said Andrea Ghez, who directs the UCLA Galactic Center Group. “For us, it’s visceral, it’s now—but it actually happened 26,000 years ago!” said Andrea Ghez, who directs the UCLA Galactic Center Group about photons from a star known as S0-2 that makes a complete orbit in three dimensions around the supermassive black hole at the center of the Milky Way confirming Einstein’s theory of general relativity. The full orbit takes 16 years; the black hole’s mass is about four million times that of the sun.
