Beschreibung:
The concept of time has fascinated humanity throughout history, and remains one of the biggest mysteries in science and philosophy. Yet a deeper understanding of nature at a fundamental level can only be achieved through a comprehension of this strange fourth dimension. Furthermore, the origin of the universe is closely intertwined with the puzzle of time: Did time emerge at the big bang? Why does the direction of time 'conspire' with the remarkably ordered initial state of the universe?
Some of the brightest minds currently working in the field of cosmology discuss the two most important questions about time: What is it? and, If time can be seen as a kind of arrow, then why do the cosmic and thermodynamic arrows of time agree?
