Laser swords, time machines, matter transporters - before the turn of the millennium, movies, books and television promised some extraordinary future technology. Now we’re twenty years into the next century and CrowdScience listeners are wondering: Where is it all? Marnie Chesterton delves into the sci-fi cupboard to dust off some imaginary gadgets and find out if any are finally becoming reality. How far into the future will we have to go to find a time machine as imagined by H.G. Wells in 1895? Where are the lightsabers wielded by fictional Jedi? Why are we still using cars, planes and trains when a matter transporter or a flying taxi could be so much more convenient? Marnie is joined by a panel of experts to find out if and when any of these much-longed for items are going to arrive. Presenter Marnie Chesterton. Producer Jennifer Whyntie (Photo: Dr Who, Tardis.
