The largest black holes in the Universe can be found by their shadows. Surprisingly, the farther away such a hole is, the sharper its shadow appears on the ancient light of the Big Bang. This discovery puts an end to the existence of black holes heavier than a hundred million billion suns.
🎯 If one of these black holes were at the center of the Milky Way, its edge (the event horizon) would lie beyond the orbit of Pluto.
🎬 In Interstellar, Gargantua was depicted, but real supermassive black holes are millions of times more massive.
