Black Holes _ by Don Nardo
The concept of black holes consistently grips the
human imagination. Many strange and frightening
creatures and objects have been invented in
mythology and fiction, and modern scientists have
revealed a number of equally bizarre and disquieting
things in the natural world. But none of these quite
compares to the idea of the black hole—an object
whose gravitational pull is so great that even light
cannot escape it, and a place where most of the normal
laws of nature break down. In the words of
noted physicist Kip Thorne, one of the world’s leading
experts on black holes:
Of all the conceptions of the human mind,
from unicorns to gargoyles to the hydrogen
bomb, the most fantastic, perhaps, is the black
hole: a hole in space with a definite edge into
which anything can fall and out of which nothing
can escape, a hole with a gravitational force
so strong that even light is caught and held in
its grip, a hole that curves space and warps time.
