"What are black holes? What does E=mc2 mean? How did the universe begin? How will it end? How is the twin paradex resolved? The exact answers to these questions are provide in the text entitled "Theory of Relativity". You will also find the exact answers for questions about the fundamental nature of matter and energy in the universe. The complex concepts included in this text have been simplified in the light of modern development." (jacket)
