Black holes may not be black—or even holes. A new study says their true nature could finally explain the origins of dark matter and fast radio bursts.
What if you fell into a black hole? It's a good thing that the nearest black holes are thousands of light-years away from us. From a distance, black holes act like any other massive objects in the universe. In fact, if you were to replace the sun with a solar-mass black hole, th...
