By tracking the death spiral of cosmic gas at the center of a galaxy called NGC1097, scientists figured that material moving at 110,000 miles an hour would still take eons to cross into a black hole.
Black holes are drains in space that have gravitational pull so strong that nothing, not even light, can escape. Huge ones are believed to lurk at the centers of many galaxies including the Milky Way, which contains the sun."
