Mark Frauenfelder:
The massive undersea earthquake that caused the tsunami gave a boost to our planet’s spin. As a result, days will be a fraction of a second shorter from now on.
Richard Gross, a geophysicist with NASA’s Jet Propulsion Laboratory in California, theorized that a shift of mass toward the Earth’s center during the quake on Sunday caused the planet to spin 3 microseconds, or 3 millionths of a second, faster and to tilt about an inch on its axis.
