From the world-renowned physicist and bestselling author of The Elegant Universe and The Fabric of the Cosmos, a captivating exploration of deep time and humanity's search for purpose In both time and space, the cosmos is astoundingly vast, and yet is governed by simple, elegant, universal mathematical laws. On this cosmic timeline, our human era is spectacular but fleeting. Someday, we know, we will all die. And, we know, so too will the universe itself. Until the End of Time is Brian Greene's breathtaking new exploration of the cosmos and our quest to understand it. Greene takes us on a journey across time, from our most refined understanding of the universe's beginning, to the closest science can take us to the very end. He explores how life and mind emerged from the initial chaos, and how our minds, in coming to understand their own impermanence, seek in different ways to give meaning to experience: in story, myth, religion, creative expression, science, the quest for truth, and our longing for the timeless, or eternal. Through a series of nested stories that explain distinct but interwoven layers of reality-from the quantum mechanics to consciousness to black holes-Greene provides us with a clearer sense of how we came to be, a finer picture of where we are now, and a firmer understanding of where we are headed. Yet all this understanding, which arose with the emergence of life, will dissolve with its conclusion. Which leaves us with one realization: during our brief moment in the sun, we are tasked with the charge of finding our own meaning.
