Read this excerpt from "Why Are They Called Black
Holes?"
Astronomers can observe these effects. For example,
when a black hole passes through a cloud of dust, it pulls
the dust inside it like a big gravity-powered vacuum
cleaner. When a star passes too close to a black hole, the
black hole pulls it in and breaks up the star, spewing giant
flashes of high energy called gamma-ray bursts. And when
scientists see light bending even though there is no visible
matter nearby, they have evidence that there is an invisible
black hole
In this excerpt, the author's use of description
