NEW YORK â€” Earth's days may have gotten a little bit shorter since the massive earthquake in Chile, but don't feel bad if you haven't noticed.
The difference would be only about one-millionth of a second.
Richard Gross, a scientist at NASA's Jet Propulsion Laboratory in Pasadena, Calif., and colleagues calculated that Saturday's quake shortened the day by 1.26 microseconds. A microsecond is one-millionth of a second.
The length of a day is the time it takes for the planet to complete one rotation â€“ 86,400 seconds or 24 hours.
Now I have a good reason for why I did not get all the housework my wife wanted me to do yesterday done. As soon as she gets up in the morning I am going to tell her it was not my fault but the earthquake in Chile
