The Structure of the Universe by Paul Halpern, Ph.D., originally published in 1996, is a tour of the knowledge of the deep reaches of space and predictions for its future.

Technological marvels such as the Hubble Space Telescope are revealing a wealth of information about the deepest reaches of space. After decades of research, scientists now believe they are closer to discovering the 'missing matter,' the invisible stuff left over from the Big Bang that will determine the ultimate fate of the universe. With each discovery new light is shed on scores of old questions, and at the same time new questions arise.
