There are four fundamental forces of nature in our universe. Three of them affect the atomic level, and one applies to the planets. How can we unify all four forces in a single model? This is a very exciting question to which physics has not yet found an answer – or not quite. The theory of quantum gravitation is working on answering this great universal question.
Claus Kiefer takes his readers on an entertaining journey through the theory of relativity and quantum theory, time’s arrow and cosmology, all the way to quantum gravity and quantum cosmology. He explains what is behind phenomena such as black holes, Schrödinger’s cat, dark energy, strings and the wave function of the universe, sketching out the exciting new theory and its answer to the key question of modern physics.
