How to Build a Time Machine

This look at time travel technology gives “a solid overview of some of the quirkier corners of physics, with an entertaining connection to pop culture” (Kirkus Reviews).

In How to Build a Time Machine, physicist Brian Clegg provides an understanding of what time is and how it can be manipulated. He explores the fascinating speculations and the remarkable possibilities of real time travel that emerge from quantum entanglement, superluminal speeds, neutron star cylinders and wormholes in space. With the paradoxes of time travel echoing in our minds, will we realize that travel into the future might never be possible? Or will we realize there is no limit on what can be achieved, and take on this ultimate challenge? Only time will tell.

He covers most of the themes advanced by science fiction, plus some of the more adventurous scientific minds, generally avoiding math or tricky technical details.” —Kirkus Reviews

“Explain[s] quantum entanglement and superluminal speeds in terms that even a technophobe could understand.” —Publishers Weekly

“A genuinely intriguing book.” —Booklist

“Clegg excels at making science accessible.” —Library Journal
