If mass were lighter in less dense surroundings, e.g. the edges of a galaxy, this would be the same as the gravitational constant of the universe being smaller and particles would orbit faster at the edges and explain the strange spin of galaxies, right?
In a sense, you are assigning a preferred reference frame to gravitational force over distance. If this were true, it would be easily observed within the solar system [proportionately less gravity effects from more distant planets]. But it is not true. Were that the case, Pioneer and the Cassini probe would have been way off course [not to mention missions to the moon]. The same effect would be also be obvious in particle accelerators.
