What are black holes?
Where did they come from?
Can spaceships disappear into a black hole?
And, since outer space is black, how do we know black holes really exist?
In this book, author Isaac Asimov plays science detective. He tracks down the clues, one by one, in the fascinating mystery of the black holes in space.
A good and reasonably current introduction to the ultimately dense. Older readers might find a book like The Collapsing Universe more to their liking, but younger readers should find this a delight.
