A German newspaper reported last week that 13-year-old Nico Marquardt corrected a few glitches in NASA's estimates regarding the chances of a certain asteroid colliding with Earth. NASA concluded that the Apophis space rock has only a 1 in 45,000 chance of knocking into us, but this school-kid announced that the space agency had missed a few zeros, suggesting that the probability is closer to 1 in 450. And while quite a few news reports backed him up, even claiming that NASA agreed Marquardt was correct, the space agency is sticking to its estimates.
