Scalar-tensor-vector gravity

Scalar-tensor-vector gravity

Scalar-tensor-vector gravity (STVG) is a theory of gravity which, like other theories including Modified Newtonian dynamics (otherwise known as "MOND"), attempts to explain the rotation of galaxies by doing away with dark matter. Unlike MOND, STVG explains galactic clustering as well. Developed by Joel Brownstein and John Moffat, researchers at the Perimeter Institute for Theoretical Physics and the University of Waterloo.
