Igor Novikov has been hailed as "Russia's answer to Stephen Hawking." In this popular account of the cosmic importance of black holes, he explores the properties and significance of these mysterious phenomena, which represent the most condensed state of matter in the Universe. Black holes are formed by the force of gravity, warping space and time, crushing stars and perhaps galaxies, too, until they fall in on themselves. Novikov's fascinating account illuminates this most enigmatic feature of our Universe with exemplary clarity, illustrated with a series of inspired cartoon drawings.

Page 1 - Of all the conceptions of the human mind from unicorns to gargoyles to the hydrogen bomb perhaps the most fantastic is the black hole: a hole in space with a definite edge over which anything can fall and nothing can escape; a hole with a gravitational field so strong that even light is caught and held in its grip; a hole that curves space and warps time.
