โœจMatter spiraling into a black hole is torn apart and glows so brightly that it creates the brightest objects in the Universe โ€“ quasarsโœจ

โœจFor black holes, distant observers will see only the outside of the event horizon, while individual observers falling into the black hole will experience quite another "reality." General relativity predicts that for distant observers outside the horizon, they will experience the three space-like coordinates and one time-like coordinate, as they always have. For someone falling into a black hole and crossing the horizon, this crossing is mathematically predicted to involve the transformation of your single time-like coordinate into a space-like coordinate, and your three space-like coordinates into three time-like coordinates. Along any of these three former space-like coordinates, they now all terminate on the singularity; you're experiencing them as time-like now. All choices always terminate on the singularityโ€”at least in the case of a non-rotating black hole. The coordinate which used to measure external time now has a space-like character which affords you some wiggle room, but dynamically, in terms of these new reversed space and time coordinates, you find that no stable orbits about the singularity are possible no matter what you try to do. Without any stable orbits, and the inexorable freefall into the singularity, relativists often refer to this as the collapse of space-time geometryโœจ

โœจIn 1974, Stephen Hawking showed that black holes evaporate. According to quantum mechanics, pairs of virtual particles are constantly being created and then annihilating each other near black holes (as well as everywhere else in the universe). On occasion, one of the pair of particles ends up inside the black hole's event horizon, and so cannot annihilate its pair, which is forced to become a real particle. This results in a slight increase in the total mass-energy of the outside universe, and that mass-energy has to come from the black hole, whose mass-energy is slightly decreased. Eventually (after an incredibly long time for normal-sized black holes) the black hole would disappear in an explosion of particles and energyโœจ

โœจA super massive black hole is thought to inhabit the heart of every galaxy, including the Milky Way. The more massive the black hole, the bigger the galaxy. Some super massive black holes are billions of times the mass of the Sun, with events horizons larger than the solar systemโœจ

โœจThe black hole at the heart of elliptical galaxy M87 weighs in with a mass of at least 2 billion times that of our Sun. Travelling at near light speed from the disk of gas and dust orbiting the black hole, is a 5,000 light year long jet of matter ejected from the galaxyโœจ
