The “g
8、randfather paradox” is the argument that many people use to suggest that time travel is impossible. What if you went back in time and prevented your grandfather from meeting your grandmother so that your mother was never born? Then you would never have been born . and so on.Until very recently such
9、arguments led most scientists to believe that time travel could never exist outside science fiction. But amazingly, some interpretations of the weirdness of the quantum world now suggest that time travel is possible at least in theory.Gravity and black holesEinsteins theory of relativity brought spa
10、ce and time together in a single, four-dimensional arrange-ment that he called space-time. We know that we can travel forwards, backwards and sideways in space, so why not forwards and backwards in time?Four dimensions are difficult to imagine, so physicists usually suggest you think of space-time a
11、s a rubber sheet stretched out flat. If there are no large masses around, the sheet stays flat, and so any object placed on it will move around in straight lines. But a large mass, such as the sun, makes a dip in the sheet because it actually warps space-time. Now any other object with smaller mass,
12、 like our earth, moving about in space-time rolls into the dip as it comes past the sun. It appears “attracted” to the large mass. This effect of warping space-time is what gives rise to gravity.The Universe is full of heavy objects exerting gravitational effects and the net result is that space-tim
13、e is not flat at all but curved. Everything, including light, has to follow curved paths in space-time. We know Einstein was right about this because astronomers can sometimes see distant stars that ought to be masked by nearer objects such as the sun. Instead of traveling in straight lines and henc
14、e being blocked, the light from the stars bends round the obstruction.When a star reaches the end of its life it mat collapse inwards under the influence of its own gravity to such an extent that all its matter becomes concentrated into an extremely dense object, a fraction of its original size. Thi
15、s is a black hole. Black holes have such a huge gravitational pull that nothing can escape from them, not even light. We cannot see them but we have good evidence that they are being pulled about by a nearby invisible object with enormous mass.What does a black hole do to space-time? Relativity pred
16、icts that at the center of a black hole is an infinitely dense point, called a singularity, within which all the normal laws of physics no longer apply. Time, space, matter and energy no longer have any well-defined meaning. Einsteins equations show that such a singularity doesnt just make a dip in the imaginary rubber sheet of space- time, it makes a tunnel that goes
