5、le 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 m

6、eans 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 diff

7、icult 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. T

8、he 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 sti

12、sing DNA fingerprinting techniques to do the decoding.2DNA is the substance found in the chromosomes（染色体）of a cell.A chromosome is a chain of genes.Each gene carries a piece of genetic information.At any one moment in a cell,thousands of genes are turned on and off to produce proteins（蛋白质）.The chall

13、enge for scientists is to find out what role each gene plays in protein production.At some point this decoding will be complete.Then scientists will have a map of an ideal genome,or a picture of the total genetic nature of a human being.The ideal genome is called a consensus（交感）genome.Everything wor

14、ks well in a consensus genome.3But no one in the world has a consensus genome.Everyones genome is different from the ideal.These differences are referred to as genetic mutations（突变）.Genetic mutations in a persons genome mean that the person has a greater than average chance of suffering from health
