If memmory serves me correctly,(I have many dead brain cells), the earth does use energy to orbit. It uses the radiation and magnetic energy from the sun. When the sun burns out in about a gazillion years, the earth and the solar system we currently live in will just float away into a big black hole where the ewoks live.......

Nope, never guessed a stupid question about a piece of wire would go this far.......

Time to put the beer away and grab the Jack.......
