Are you a science fiction fan curious to see how close scientists have come to understanding or recreating the theories or gadgets of your favorite book or movie? Do you think much of the gadgetry and action of science fiction stories are completely impossible and want to see what we really can do, and what we might be able to do in the future? Here are some books that will help you understand how realistic some ideas like time travel really are, and how theories and realities surrounding our universe and the possibilities have changed in recent years.

Time Travel and Warp Drives: a Scientific Guide to Shortcuts Through Time and Space by Allen Everett and Thomas Roman
Lays out what humans really know about time and space and how to bend it to our will, and explains just how close we are to some of the ideas of science fiction novels.

Physics of the Impossible: a Scientific Exploration into the World of Phasers, Force Fields, Teleportation, and Time Travel by Michio Kaku
Looks at the scientific principles behind the technology of the future, examining the theoretical basis, as well as limitations, of the laws of physics to discuss how seemingly impossible devices could become commonplace in the future.

Spooky Action at a Distance: the Phenomenon that Reimagines Space and Time and What it Means for Black Holes, the Big Bang, and Theories of Everything by George Musser
Presents a tour of modern physics that examines the new understanding of nonlocality–the ability of particles to affect each other across the vastness of space.

Walking Zero: Discovering Cosmic Space and time Along the Prime Meridian by Chet Raymo
A noted science writer and author of The Path offers an illuminating study of the interconnections among science, faith, psychology, and the arts in terms of the evolution of the human understanding of space and time as he walks along the Prime Meridian, the line of zero longitude and the standard for world maps and clocks, from Brighton to the North Sea.

What is Relativity?: an Intuitive Introduction to Einstein’s Ideas, and Why They Matter by Jeffrey Bennett
An astrophysicist offers an entertaining introduction to Einstein’s theories, explaining how well they have held up to rigorous testing over the years, and even describing the amazing phenomena readers would actually experience if they took a trip through a black hole.

Once you figure out hoe time travel works, or somehow or other gain a little extra time, you might want to explore further with: The Fabric of the Cosmos: Space, Time, and the Texture of Reality by Brian Greene, A Brief History of Time: From the Big Bang to Black Holes by Stephen W. Hawking, Endless Universe: Beyond the Big Bang by Paul J. Steinhardt and Neil Turok, Cosmos by Carl Sagan, The Science of Star Wars by Jeanne Cavelos, The Physics of Star Trek by Lawrence M. Krauss, or Physics of the Future: How Science Will Shape Human Destiny and our Daily Lives by the Year 2100 by Michio Kaku.
