> Not entirely (un)related: I wonder if the earth's rotational speed could be changed significantly if the entire 6 billion (6.000.000 or 6,000,000) of us were to run simultaneously in the same east-west direction? You see, I've made a rash promise to increase the length of the day, and I'm wondering whether the most effective way is to redefine time or decrease the earths rotational speed.

If the person you promised it to is anything like me, he won't accept redefining time because you've not changed the length of the day, only the method of measuring it.

I don't know if getting everyone (BTW, you missed three 0's off) to run in the same direction woukd work, though I suspect it would. But people living near a west coast probably wouldn't be too happy with the idea.

A bit late perhaps, but one option might be to make the promise in winter and claim success in summer.
