Up in Cockeysville, Michael Vito imagines Earth with no moon: "What would happen to the Earth and the ... weather if our moon were totally destroyed?" Assuming Luna simply vanished, and didn't explode and rain moonrocks on us, NASA says ocean tides would be a third as high, and more constant week to week. But they would persist, thanks to the sun's gravity. Earth would spin faster, like Jupiter, shortening the day. Our winds would be stronger and steadier, west to east, bringing less variable weather and better surf.
