Explore the changing ideas about our Universe -- from the flat Earth to black holes.

Here is a spectacular, thought-provoking, and highly informative guide to the mysteries of the Universe. Superb full-color photography of scientific instruments, experiments, and innovative 3-D models reveals the discoveries and latest research that have transformed our understanding of the Universe. See how time and space are measured, the world's largest telescope, in Hawaii, a sonic tape measure, inside an atom, and how pulsars flicker on and off with amazing precision. Learn how far it is to the Moon, whether time can stand still, how to pop through a wormhole, how Einstein helped prove that everything is made of atoms, when the world's oldest observatory was built, and why "London Time" was introduced in 1840. Discover how the Universe is expanding, whether Schrodinger's cat is dead or alive, bouncing universes, what astronomers call "spaghettification", the difference between biotime and biospace, how ripples in spacetime happen, and much, much more.
