Black Holes

　　Most scientists agree that black holes exist but are nearlyimpossible to locate.A black hole in the universe is not a solidobject,like a planet,but it is shaped like a sphere（球体）.Astronomers（天文学家）think that at the center of a black hole there isa single point in space with infinite（无限的）density（稠密）.This single pointis called a singularity （奇点）.If the singularity theory is correct,itmeans that when a massive star collapses,all the material in itdisappears into the singularity.The center of a black hole would notreally be a hole at all,but an infinitely dense point.Anything thatcrosses the black hole is pulled in by its great gravity.

　　Although black holes do exist,they are difficult to observe.These are the reasons.

　　● No light or anything else comes out of black holes.As a result,they are invisible to a telescope.

　　● In astronomical terms,black holes are truly.For example,a blackhole formed by the collapse of a giant star would have an eventhorizon（视界）only 18 miles across.

　　● The nearest black holes would be dozens of light years away fromEarth.One light year is about 6 trillion（万亿）miles.Even the mostpowerful telescopes could not pick out an object so small at such agreat distance.

　　In 1994 the Hubble Space Telescope provided evidence that blackholes exist.There are still answers to be found,however,so black holesremain one of the mysteries of the universe.

　　16.Black holes are part of space.
