Do we live in a digital simulation, asks Anil Ananthaswamy (3 September, p 30). Perhaps we could try to decide the question by crashing it. Presumably, the more heavily we load the simulation, the more likely it is to fail. By running ever more digital simulations within our own universe, we might perhaps be able to bring our parent simulation to its knees - although we might then not be in a fit state to notice. Doing too much quantum computing might also not be wise. Even thinking too much and making too many decisions could be dangerous. If such seemingly innocuous acts really do spawn universes by the gazillion, we should spare a thought for our poor host simulation.
