On Time

In On Time, physicist Jim Al-Khalili explores the enigmatic nature of time, addressing enduring questions about its beginning, direction, and reality. Through a careful examination of quantum mechanics, general relativity, and thermodynamics, he presents various insights on how time can be understood differently across these domains. Al-Khalili argues against the notion of time as an illusion, positing instead that it is a fundamental feature of our universe. This thought-provoking work promises to reshape readers' perspectives on time and their existence within it.
