Mysterious object may be the lightest black hole we’ve ever seen

A dense object about 40,000 light years away is lighter than any black hole seen before, but heavier than any neutron star, leaving astronomers unsure what they are looking at

A white hole is a theoretical solution to Einstein's field equations - a region which cannot be entered at all from the outside. In a sense, therefore, they are the time-reversed opposites of black holes. The theory suggests that a black hole is connected to a white hole via a tunnel called an Einstein-Rosen bridge (wormhole). Matter falls into the black hole and is expelled via the white one. Some theorists even argue that the Big Bang itself is a white hole, gushing out matter and creating a new universe while, on the other end, invisible and unreachable, is a black hole in a totally different universe.
