"The massive 8.8 earthquake that struck Chile may have changed the entire Earth's rotation and shortened the length of days on our planet, a NASA scientist said Monday."
Wow! I'm not sure whether to be concerned or not about a shorter day by 1.26 milliseconds (though really, I need longer days for a bit more sleep, not shorter ones). But the idea of a massive earthquake shifting the earth's axis and rotation totally rocks my world.
I'm trying to get my head around the idea that something that happens inside the planet (not an outside force acting on it) can alter its rotation. That's wild! (And a little scary...)
