correct mistake about electric force being always centripetal (it is centrifugal for same-charge particles)

Think 2d surface of planet in 3d space, but 3d surface of universe on 4d multiverse space. "Space is to place as eternity is to time." | |

Basically, a strong gravitational field actually slows down time. (If you approach very near a Black hole, time becomes very slow indeed, and at the singularity itself, it may well stop, though we don't have a good idea what exactly happens.) | |
