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.

Katie Mack writes in a casual, entertaining style. It's clear she finds all of this absolutely fascinating. And she sprinkles the writing with funny stories and quotes and side notes to get across the basics of quantum mechanics, Higgs fields, high-energy physics and the like without delving too much into the math. But the math, and the measurements, are important, because as it turns out, very small changes in how things work at the quantum level can have major implications on the universe's ultimate fate.

The last time I read about this topic in anything resembling depth was about a decade ago. Since then there've been major discoveries in …
