Astrophysicists think theres a supermassive black hole at the center of the Milky Way galaxy. The European Research Council has given 14 million euros ($19.3 million) to the creators of BlackHoleCam, a project that will use radio telescopes and supercomputers to try to prove the existence of what Luciano Rezzolla, a principal investigator for BlackHoleCam, calls one of the most cherished astrophysical objects. It wont be able to image the black hole itself, instead using the event horizon that it expects to see to confirm the holes existence. The event horizon — a phenomenon predicted by Einstein — is the boundary of spacetime beyond which the pull of gravity is so great that escape is impossible. Space.com reports the Milky Ways black hole should betray its event horizon by casting a dark shadow over bright radio wave emissions given off as gas is pulled into the black hole.
