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 black hole formed by the collapse of a giant star would have an event horizon（视界）only 18 miles across. ● The nearest 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 answers to be found,however,so black holes remain one of the mysteries of the universe. 16.Black holes are part of space.
