For 10 points, what are these objects in outer space from which supposedly nothing, not even light, can escape?
The size of these objects is given by the Schwarzschild ("SHWARTZ child") radius. According to quantum mechanics, these objects emit Hawking radiation. One of them, Sagittarius A Star, sits at the center of our galaxy and has four million times the mass of our sun.
