For years, black holes have captivated the imagination of people. What is this galactic hell that traps matter and light, devouring anything that falls into it?

What are these dark zones that operate detached from our own universe and its laws? Can they be transformed into time machines and open gates to parallel universes?

Black holes are objects that have collapsed gravitationally. They have a mass equal to millions or even billions of times that of the Sun, tightly compressed into a space no larger than that of our solar system.

In this book, which combines knowledge with entertainment, the author of Time - A Traveler's Guide, Clifford A. Pickover, takes us on a journey into a world as fascinating as it is paradoxical.

Starting each chapter with a fictional dialogue between two explorers experimenting with a black hole lost somewhere in space, the author presents a wide range of topics in an accessible and enjoyable manner: from the structure of a black hole and its tidal forces, quantum foam and wormholes in spacetime, to mathematical 'black holes' and fractals.

He addresses the question of whether we could live inside a black hole and what scientists mean by the paradoxical phrase 'black holes have no hair,' while also including original entertaining games involving black holes.
