Most of us have dreamed of traveling through time, backward or forwards, faster than those around us. And surprisingly, recent work has shown us that time travel is far more than just a dream. In fact, a number of researchers have explored, and are currently exploring, the legitimacy of time travel. While they haven’t quite gotten to the point where they are able to time travel themselves—these researchers have found some concrete science backing it up. This past June, I met with James Beacham, a particle physicist at the European Organization for Nuclear Research (CERN), at Brain Bar Budapest, a festival focused on science and the future, to talk about the ways in which time travel has enraptured humanity and discuss both the logistical and technical potential of time travel. Beacham began by outlining the ways that, according to Einstein’s theories, time travel is technically possible through a number of different methods. “If space can be bent, then spacetime can be bent.” One proposed method of time travel is via wormholes. “We know that space can be bent. If space can be bent by, say, gravity, then spacetime can be bent,” Beacham said. To clarify, space is the three-dimensional body in which all things in the universe move. Spacetime, however, is the combined concepts of space and time into a four-dimensional continuum. You may have even seen spacetime portrayed as a fabric, manipulated by energy. If spacetime can be bent, Beacham continued, it’s theoretically possible that time can be bent.
