The Facts Behind Science Fiction

Two new titles from Chicago look at the reality and speculation behind the staple fare of science fiction.

Allen Everett and Thomas Roman. Time Travel and Warp Drives: A Scientific Guide to Shortcuts Through Time and Space. University of Chicago Press. December 2011.

From the Publisher: Sci-fi makes it look so easy. Receive a distress call from Alpha Centauri? No problem: punch the warp drive and you're there in minutes. Facing a catastrophe that can't be averted? Just pop back in the timestream and stop it before it starts. But for those of us not lucky enough to live in a science-fictional universe, are these ideas merely flights of fancy—or could it really be possible to travel through time or take shortcuts between stars?

Cutting-edge physics may not be able to answer those questions yet, but it does offer up some tantalizing possibilities. In Time Travel and Warp Drives, Allen Everett and Thomas A. Roman take readers on a clear, concise tour of our current understanding of the nature of time and space—and whether or not we might be able to bend them to our will. Using no math beyond high school algebra, the authors lay out an approachable explanation of Einstein's special relativity, then move through the fundamental differences between traveling forward and backward in time and the surprising theoretical connection between going back in time and traveling faster than the speed of light.

They survey a variety of possible time machines and warp drives, including wormholes and warp bubbles, and, in a dizzyingly creative chapter, imagine the paradoxes that could plague a world where time travel was possible—killing your own grandfather is only one of them! Written with a light touch and an irrepressible love of the fun of sci-fi scenarios—but firmly rooted in the most up-to-date science, Time Travel and Warp Drives will be a delightful discovery for any science buff or armchair chrononaut.

Jeffrey J. Kripal. Mutants and Mystics: Science Fiction, Superhero Comics, and the Paranormal. University of Chicago Press. November 2011.

From the Publisher: In many ways, twentieth-century America was the land of superheroes and science fiction. From Superman and Batman to the Fantastic Four and the X-Men, these pop-culture juggernauts, with their "powers and abilities far beyond those of mortal men," thrilled readers and audiences—and simultaneously embodied a host of our dreams and fears about modern life and the onrushing future.

But that's just scratching the surface, says Jeffrey Kripal. In Mutants and Mystics, Kripal offers a brilliantly insightful account of how comic book heroes have helped their creators and fans alike explore and express a wealth of paranormal experiences ignored by mainstream science. Delving deeply into the work of major figures in the field—from Jack Kirby’s cosmic superhero sagas and Philip K. Dick’s futuristic head-trips to Alan Moore’s sex magic and Whitley Strieber’s communion with visitors—Kripal shows how creators turned to science fiction to convey the reality of the inexplicable and the paranormal they experienced in their lives.

Expanded consciousness found its language in the metaphors of sci-fi—incredible powers, unprecedented mutations, time-loops and vast intergalactic intelligences—and the deeper influences of mythology and religion that these in turn drew from; the wildly creative work that followed caught the imaginations of millions. Moving deftly from Cold War science and Fredric Wertham's anticomics crusade to gnostic revelation and alien abduction, Kripal spins out a hidden history of American culture, rich with mythical themes and shot through with an awareness that there are other realities far beyond our everyday understanding.

A bravura performance, beautifully illustrated and brimming over with incredible personal stories, Mutants and Mystics is that rarest of things: a book that is guaranteed to broaden—and maybe even blow—your mind.
