She describes primordial black holes as 'awfully cute in a terrifying theoretical kind of way', antimatter as 'matter's annihilation-happy evil twin' and the universe as 'frickin' weird'. Mack's enjoyment of physics stands out - and is contagious.

And I have found myself staring out of the window, meditating about the end of it allObserver Books of the Year - Carlo RovelliWitty, clear and upbeatGuardian - Bill ClintonAn engrossing and often funny tour of all the ways our cosmos might come to a close. I have learned from her plenty of things I did not know. Katie Mack is a great scientist, a passionate inquirer of nature, a great companion in this exploration, full of wit and lightness. The End of Everything is a wildly fun, surprisingly upbeat ride to the farthest reaches of all that we know. Amid stellar explosions and bouncing universes, Mack shows that even though we puny humans have no chance of changing how it all ends, we can at least begin to understand it. This captivating story of cosmic escapism examines a mesmerizing yet unfamiliar physics landscape while sharing the excitement a leading astrophysicist feels when thinking about the universe and our place in it. Our universe could collapse in upon itself, or rip itself apart, or even - in the next five minutes - succumb to an inescapable expanding bubble of doom. Guiding us through major concepts in quantum mechanics, cosmology, string theory and much more, she describes how small tweaks to our incomplete understanding of reality can result in starkly different futures. With lively wit and wry humour, astrophysicist Katie Mack takes us on a mind-bending tour through each of the cosmos' possible finales: the Big Crunch, Heat Death, Vacuum Decay, the Big Rip and the Bounce. But what happens at the end of the story?
