Time travel is a science fiction staple, inspiring the plots of countless books, movies, and Star Trek episodes. But while basic physics allows for the possibility of moving through time, practical concerns like the “Grandfather Paradox” (in which a traveler jumps back in time, kills his grandfather, and therefore prevents his own existence) seem to stand in the way.
In a July 16 SFI Community Lecture in Santa Fe, MITs Seth Lloyd proffered a mode of time travel that eliminates any events that could later prove paradoxical, making this phenomenon both theoretically possible and creatively irresistible, whether you’re an astrophysicist, a science fiction writer, or a daydreamer.
