¹ As far as mysteries of the universe go, the complex phenomena known as black holes rank among the most spectacular. ²Called "black" because its gravitational field is so powerful as to be able to suck in light, a black hole is believed to be formed when a particularly large star runs out of fuel and collapses upon itself. ³Although a black hole can't be seen, it can be detected by the huge emissions of x-ray radiation given off by matter as it falls into the hole. ⁴It is this very property of black holes-the ability to turn matter directly into energy-that might one day make them a vital source of energy. ⁵Some scientists believe that black holes may play an important role in the fate of the universe. ⁶Some also believe that black holes will eventually swallow all the matter in existence.
