Mass > Energy-Gravity?

  1. Aug 11, 2008 #1
    Hello all,
    I have am just a curious layman wondering qualitatively what happens to somethings gravity (field?) if some or all of it's mass is converted to energy.
    Thank you

    P.s. Sorry if this is the wrong section for this.

    No, because mass and energy are basically the same thing. Gravity depends on the "mass-energy tensor" not just mass.

    To expand on what HallsofIvy said, there would be no difference in gravitational field with a source mass, and a gravitational field with an equivalent source energy (If you use e=mcc to have equal energy and mass). Hope this helps,

    Thank you both very much.
