Puzzles and Paradoxes in Relativity and Cosmology

Einstein's Special and General theories of Relativity are full of predictions which are difficult to believe - like Time Dilation and Length Contraction. Cosmology too is full of puzzles such as the fact that some of the galaxies we can see may be receding from us faster than the speed of light. This book attempts to explain these and other paradoxes using little more than High School Math and clear thinking.
