Black Holes Most scientists agree that black holes exist but are nearly impossible to locate. A.black hole in the universe is not a solid 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 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. Anything that crosses 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 tiny. For example, a black h A. Right B. Wrong C.
