In the Judeo-Christian West, however, time is a line, marching steadily from the past to the future. As Lippencott puts it, "God never moves backward." Deward Walker, an anthropologist at the University of Colorado, Boulder, argues that this way of viewing time is "part of the reason we have...
It gets even worse. In some versions of M theory--the latest rage in physics, which attempts to meld relativity and quantum theory--there may be more than three dimensions of space and more than one dimension of time. What does that mean? Even the experts have no clue. "We...
This elasticizing of space-time means, for example, that observers might disagree over which of two events happened first--and both could be right. Even more bizarrely, physicists including Stephen Hawking have seriously discussed the possibility that relativity might make it feasible (though not with any technology we know of...
Does that mean you could go back, kill your own grandfather and keep yourself from being born--a seeming absurdity? Maybe not, say some physicists. In one interpretation of quantum physics, the world splits at each moment into an infinite number of universes that proceed in parallel; if you killed...
