Einstein's Dreams by Alan Lightman is a poetic and imaginative exploration of time, told through a series of fictional dreams experienced by Albert Einstein while developing his theory of relativity. Each dream envisions a unique and surreal world governed by different conceptions of time—cyclical, frozen, reversed—offering profound reflections on human experience, relationships, and the nature of existence. Blending science, philosophy, and artful storytelling, Lightman crafts a deeply moving meditation on how we perceive and live within the passage of time.
