From: BURT on 9 Feb 2010 20:40 Objects carry their fields with them. Therefore the field will move slower than light along with its particle. The range of the force determines the size of the field that will flow through spacetime with its particles motion. Mitch Raemsch

Gravity is a constant (unlike photons, mass of universe doesn't change) What's the problem if the velocity of gravity were 2c, or faster (<9e16 m/s)? What makes you think gravity is any slower than 2c? ~ BG
