Einstein showed Newton was wrong about gravity. Now scientists are coming for Einstein.
New research confirms Einstein's theory of gravity but brings scientists a step closer to the day when it might be supplanted by something new.
Albert Einstein can explain a lot, but maybe not black holes. Scientists believe that within the inky depths of these massive celestial objects, the laws of the universe fold in on themselves, and the elegant model of gravity laid out in Einstein’s general theory of relativity breaks down.
They don't know precisely how or where that happens, but a new study brings them closer to the answer.
======================================================
'The study, to be published Aug. 16 in the journal Science, shows that gravity works just as Einstein predicted even at the very edge of a black hole — in this case
Sagittarius A*, the supermassive black hole at the center of our Milky Way galaxy. But the study is just the opening salvo in a far-ranging effort to find the point where Einstein’s model falls apart.'
Apparently conditions within a black hole are such that the present day physical principals behind things like gravity fail to apply. We have never looked at things under very extreme conditions, such as what happened when light from the star
S0-2 passed
Sagittarius A*, which is four million times more massive than the sun. Will Einstein's space-time curvature model still work? It did during a 1919 solar eclipse, but will it in this much more extreme case?
