Pretty, but false:
MOND, a competing theory of gravity, has been falsified by a large and long study by astronomers. Also known as TeVeS for Tensor-Vector-Scalar gravity theory, it proposed an alternative explanation to gravity in which dark energy and dark matter needn't exist.
Oh well, we'll toss that one on the LeSage gravity pile of nice ideas but back to the drawing board.
