The earthquake that struck Chile was so powerful it shifted the planet's axis enough to make it spin slightly faster, meaning our days will be shorter by 1.26 millionths of a second, according to preliminary calculations by scientists at the National Aeronautics and Space Administration.

"This is an esoteric effect that physics says has to happen," notes David Kerridge, the British Geological Survey's head of natural hazards, who studies earthquakes. "It's interesting, but it has no particular consequence on anything."
