Researchers have spent the past few years watching a black hole re-awaken roughly 300 million light-years away from Earth.

Einstein believed that black holes didn't really exist. But they do: that much we know. We don't know much else about them.

"This pushes our models to their limits and challenges our existing ideas about how these X-ray flashes are being generated." ...
