Uniform Size of Black Holes Seen

From Times Staff and Wire Reports

Nature may make black holes with cookie-cutter precision, according to an astronomer who has found such uniformity in these mysterious objects that he suggests their size may be controlled by some basic law of physics. Yale University astronomer Charles Bailyn, who gave a report on his black-hole findings at a meeting of the American Astronomical Society in Winston-Salem, N.C., said measurements of the mass of the known stellar black holes show that all but one of them are seven times the size of the sun.
