First proof that "plunging regions" exist around black holes in space
An international team led by researchers at Oxford University Physics have proved Einstein was correct about a key prediction concerning black holes. Using X-ray data to test Einstein’s theory of gravity, their study gives the first observational proof that a “plunging-region” exists around black holes: an area where matter stops circling the hole and instead falls straight
Later this year, a second Oxford team hopes to move closer to recording the first videos of larger, more distant black holes as part of a European initiative. ‘This is the first look at how plasma, peeled from the outer edge of a star, undergoes its final fall into the centre of a black hole, a process happening in a system around ten thousand light years away,’ said Dr Andrew Mummery, of Oxford University Physics, who led the study. The Oxford team has spent the last couple of years developing models for it and, in the study just published, demonstrate its first confirmed detection found using X-ray telescopes and data from the International Space Station.
