What if I told you that the world was two-dimensional? In a way that should surprise you more than if I told you it was ten-dimensional. We're all quite happy to accept that the world might be more complicated than our senses suggest — but could it be simpler? It's a possibility that Sanjaye Ramgoolam of Queen Mary, University of London, is exploring: he is developing a two-dimensional description of the world. So far the theory only applies to a toy Universe, but his results may one day give us important insights into the real world.
Dr Ramgoolam was interviewed by Plus Magazine. He described his research into a two dimensional perspective on the four-dimensional world, motivated by studies of dualities relating ten dimensional strings and four dimensional quantum fields.
