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.

Tobias wolff most likely named his short story "mortals" because the story explores the theme of people coming to terms with the idea that one day they too will die. wanting to find out what their loved ones really think of them. achieving immortalit by being "big people" while they are alive. hoping that they will have accomplished something before they die.
