Secondo questa notizia, di cui non vi è motivo di dubitare, le nostre giornate si sono accorciate, per sempre!!!!!
The Japanese earthquake may have very slightly shortened the length of a day - by about 1.8 microseconds, the US Geological Survey (USGS) says according to the Associated Press of Pakistan. It quotes the USGS as saying: "Earth's rotation changes all the time as a result of not only earthquakes, but also the much larger effects of changes in atmospheric winds and oceanic currents." It is nothing to worry about, it adds.
