Astrophysicists have detected light coming
A team of researchers recently inspected the coronal flares produced by the supermassive blackhole I Zwicky 1. They found that some of the X-rays produced by the flares we gravitational lensing , in which our view of a published today in Nature.
"Any light that goes into that black hole doesn't come out, so we shouldn't be able to see anything that's behind the black hole. The reason we can see that is because that black hole is warping space, bending light and twisting magnetic fields around itself," said Dan Wilkins, an astrophysicist at the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University and a co-author of the new research, in a Stanford University press release .
Black holes are so gravitationally intense that not even light can escape them once it is sucked in. Matter falling into black holes is pulled apart by those that occur in the Sun's corona .
The idea that black holes' intense gravity could bend light around itself was proposed by Einstein, but technology has taken a while to catch up (and still hasn't completely). "Fifty years ago, when astrophysicists [started] speculating about how the magnetic field might behave close to a black hole, they had no idea that one day we might have the techniques to observe this directly and see Einstein's general theory of relativity in action," said paper co-author Roger Blandford, a particle physicist at Stanford, in the university release.

"Reverberation has been seen in other accreting black holes, both from supermassive and stellar mass accreting black holes, but usually we need to average over many flares on a range of timescales in order to see such a signal. While this observation doesn't change our general picture of black hole accretion, it is a nice confir
More precise telescopes could sharpen astrophysicists' understanding of these physical phenomena, as well as other bizarre behaviors of black holes. Theory tends to move ahead of observations, as we're more limited by our technologies than our own creativity. But more mind-bending realizations on nature's most extreme objects are sure to come.
