Mobius time loop illustrates grandmother paradox

Steve, do you think we'll ever be able to travel in time?
It is hard to imagine what might be possible considering exponential growth of technology and major changes to the way that people communicate. It would seem likely that time travel, like other paranormal activites - might be a subjective experience that would be difficult to prove to the outside world. I can imagine time travel happening in much the same way that space travel occured in Sagan's 'Contact'.

The most common form of time travel today seems to be in the dream world - we do this every night, but the potential for conscious dreaming has only been explored on the surface.
