What is time? Does it move in only one direction? Does it have a beginning and an end? For centuries, these questions have occupied mystics, philosophers, and scientists without ever receiving a satisfactory answer. Since the publication of H.G. Wells' famous novel "The Time Machine" (1895), the idea of time travel has captivated people's imagination. Today, we know that such a thing is possible and it is not limited to the realm of scientific fiction or mythology.

Clifford A. Pickover takes us on an unpredictable journey through spacetime. As he notes, his goal was not to write a systematic study on the concept of time, but to explore the science of time travel through the presentation of a range of related topics. By combining the theory of relativity, particle physics, quantum mechanics, philosophy, psychology, Schopenhauer, and Einstein, and starting most chapters with a fictional dialogue among researchers experimenting with time at the Museum of Music in New York, the author explains fundamental scientific principles in a clear and enjoyable way, shedding light on the most mysterious and fascinating phenomenon of the universe: time itself.
