Dr Peter Riggs Shows Lectures Still Have a Place

Last night Dr Peter Riggs from the Australian National University Department of Quantum Science, in Canberra, presented "Time travel: Its implications for physics and philosophy". This was a lecture for the public, a mix of advanced science facts with some old fashioned showmanship. He asserted that time travel to the future is not philosophically problematic and theoretically possible according to Einstein. Time dilation, by traveling fast allows a one way trip to the future, as confirmed by experiment. Dr Riggs used a video projector (but he could just as well been using lantern slides), along with a model of the universe made from cardboard and sticky tape, keeping the audience enthralled with a vision of time travel.
