No wonder they want people to flunk science. Anyone with half a brain realizes that the earth is not hanging at all--and neither are the other planets (or the moon, for that matter). They are locked in orbit around the sun, itself in orbit in our galaxy around a point that is near 27 degrees of Sagittarius (the center of the galaxy). Hanging is not the correct word for this.
Instead, they are held in place by the force of gravity. The earth is kept in check by the sun's gravity, while its momentum creates a force that holds it where it is (centrifugal force). When the two are in balance, the planet is in orbit and will remain that way until something disrupts it. (Such as joke-hova blowing up Phaeton and ruining Mars, which disrupted all the planets around it from Mercury to Jupiter.) There is no way that this is "hanging", let alone "on nothing".
