No, this isn't a screenshot from the final scene of some incredible sci-fi epic, this is London. Alasdair Rae at the University of Sheffield has plotted a year's worth of capital commutes on to this eye-searing map. What's most striking about it is the amount of people travelling into (and then out of) the capital for work. Rae thinks this may say something about the economic state of the city, equating the whole thing to a supernova. He explains: 'The definition of a supernova is "A star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass." Given the displacement of people from London, this might actually be spot on.' Okay, so this may not be the most cheery conclusion, but ooh, look! Pretty colours!
