Lost in Science Fictio-mas

On this week's show we get lost in Science Fictio-mas, as the presenters look at some of the science behind the blockbuster Sci-Fi of the season to find out how it balances with the fiction. Claire Digs into Dune to find out if Sand Worms are possible on alien planets, Chris takes multiple looks at multiverses to see how likely it is any of us could be played by Toby Maguire and Stu takes a trip into the Matrix to try and figure out if we could possibly know we were living in a simulation.
