8、d object, 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 is a single point in space with infinite(无限的 )density(稠密 ).This single point is called a singularity (奇点 ).If the singularity theory is correct, it means that when a massive

9、 star collapses, all the material in it disappears into the singularity. The center of a black hole would not really be a hole at all, but an infinitely dense point.

For example, a black hole formed by the collapse of a giant star would have an event horizon(视界 )only 18 miles across. The nearest

11、black holes would be dozens of light years away from Earth. One light year is about 6 trillion(万亿 )miles. Even the most powerful telescopes could not pick out an object so small at such a great distance. In 1994 the Hubble Space Telescope provided evidence that black holes exist. There are still ans
