NEW YORK (AP) – More than a century after Albert Einstein proposed it, his theory of general relativity
With giant telescopes pointed at the center of our galaxy, a team of European researchers observed a fast-moving star approaching a monstrous black hole. They saw that the black hole distorted the lightwaves of the star, in a manner that corresponds to Einstein's theory.
The result was reported on Thursday in the journal Astronomy & Astrophysics
. Einstein's theory states that the fabric of the universe does not exist simply space, but a more complex entity called space-time, which is warped by the presence of heavy objects.
Black holes offer a good opportunity to test this idea. The one in the heart of the Milky Way is 4 million times as massive as our Sun.
The new study "feels like we're killing a dead horse," said astrophysicist Paul Sutter of Ohio State University, who was not part of the research team of Reinhard Genzel of the Max Planck Institute for Extraterrestrial Physics in Garching.
"Like any physicist in the world, I would have liked to see a tear in Einstein's relativity, Sutter said." But he tricked us. "
Scientists know that theory still does not explain everything about the universe. So, no one has ever been able to overthrow them.
Although the effects of general relativity have been seen before, this was the first discovery made by observing the motion of a star nearby was made of a supermassive black hole
"For me" That makes it so cool, "said Clifford Will, a physicist from the University of Florida who did not participate in the research.
Will hopes his peers can discover stars even closer to the black hole, where the effects of relativity would be stronger.
This finding "is really the opening sequence," he said. "The future, I think, will be very exciting."
