The End of Everything (Astrophysically Speaking)

272 pages

A cheerful, mind-bending tour through the ultimate demise of the cosmos that leaves you feeling surprisingly uplifted.

What it feels like

Reading this book feels like sitting at a bar with a brilliant, endlessly enthusiastic astrophysicist who is cheerfully explaining how everything we know will eventually be destroyed. The pace is brisk and engaging, carrying you through dense concepts like quantum mechanics and string theory on a current of witty analogies and pop-culture references. Despite the inherently apocalyptic subject matter, the mood is never bleak; instead, it is infused with a playful, mind-expanding sense of awe. Mack balances the dizzying scale of cosmic time with a grounding, conversational prose style that makes the unimaginable feel accessible. It is a perfect read for anyone who enjoys a mild dose of existential dread paired with the comforting realization of our own beautiful, fleeting insignificance.

About the book

From one of the most dynamic rising stars in astrophysics, an accessible and eye-opening look—in the bestselling tradition of Sean Carroll and Carlo Rovelli—at the five different ways the universe could end, and the mind-blowing lessons each scenario reveals about the most important concepts in physics.

We know the universe had a beginning. With the Big Bang, it went from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from dark matter to black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life. But what happens at the end of the story? In billions of years, humanity could still exist in some unrecognizable form, venturing out to distant space, finding new homes and building new civilizations. But the death of the universe is final. What might such a cataclysm look like? And what does it mean for us?

Dr. Katie Mack has been contemplating these questions since she was eighteen, when her astronomy professor first informed her the universe could end at any moment, setting her on the path toward theoretical astrophysics. Now, with lively wit and humor, she unpacks them in The End of Everything, taking us on a mind-bending tour through each of the cosmos’ possible finales: the Big Crunch; the Heat Death; Vacuum Decay; the Big Rip; and the Bounce. In the tradition of Neil DeGrasse’s bestseller Astrophysics for People in a Hurry, Mack guides us through major concepts in quantum mechanics, cosmology, string theory, and much more, in a wildly fun, surprisingly upbeat ride to the farthest reaches of everything we know.
