Mention time travel at a nerd party, and other guests will immediately respond with a grim conundrum: What happens if a time traveler goes back in time and kills one of his ancestors? This is the “Grandfather Paradox.” In a simulated environment, a team of mathematicians tested the paradox, and made a remarkable discovery: In time travel simulations, at least, history repeats itself.
