... a pleasure. Mack’s style is personal and often funny as she guides us along a cosmic timeline studded with scientific esoterica and mystery.

... far from being depressing, Mack’s account mixes a sense of reverence for the wonders of physics with an irreverent sense of humor and a disarming dose of candor.

... [a] thrilling tour of potential cosmic doomsdays.

For a book on a seemingly grim subject, it made me chuckle on many occasions, particularly the footnotes, which read like a director making snarky asides about her own film. The main text is more like an animated discussion with your favourite quirky and brilliant professor. Its references range from William Shakespeare and Nicolaus Copernicus to Friedrich Nietzsche and modern science fiction.

Mack explains each possible ending with plenty of detail but also in very clear language and plenty of comparisons and metaphors to make it as understandable and digestible as possible. I can honestly say my mind was blown at one point by an apparent paradox that Mack elucidated brilliantly. Plus, once you understand Vacuum Decay, you also get to know that our universe could wink out of existence at any moment. At only two hundred and forty pages, this book is a great stocking stuffer!.

These varying apocalyptic endings sound terrifying, but Mack tackles them with humor and authority. She uses scientific jargon that could be straight out of a science fiction movie, such as 'particle horizon,' 'cosmic inflation' and 'dark matter,' and defines these phrases in layman’s terms for those of us who are more physics-challenged. She also makes complicated theories more accessible by comparing them to relatable scenarios.

Readers with some background in physical sciences, philosophers of science, and anyone wondering what to read after Brian Greene’s Until the End of Time will relish this blend of wit and deep thought..

... smart, surprisingly funny.

... a fascinating tour of the cosmic forces—quantum vacuums, dark matter, dark energy, entropy, and gravitation among them—that may conspire to end the universe. Excelling at providing just enough scientific detail, Mack sets the scene with an exceptionally lucid history of the universe from the big bang to the present.

Mack uses humor, metaphor, and personal experience to offset her often technical descriptions, creating a delightfully unsettling narrative that explains big ideas in modern physics and cosmology through the lens of end times.
