Ticking away

To boldly go...: Paul Davies talks about his new book, How to Build a Time Machine and the theory behind it.

Travel into the future is straightforward; it merely requires the time traveller to move very fast. So far, only microsecond time trips are possible -- far too small for anyone to notice. But significant time warps would occur if a propulsion system were developed to boost a spacecraft to near the speed of light. There are many proposals for this (for example, antimatter drives), but they remain well beyond current technology.

Going back in time is far trickier...
