Dear Zanthius:

Systems of photons (that means more than one photon) have rest mass (in their center of momentum frame). Photons contribute to gravitation. Really? I didn't know. So the if the entire solar system was converted into photons, it would contribute just as much to gravitation as it does now? Until the photons were no longer located "inside" the particular place you are measuring gravitation from. Isn't it quite strange that any particle has an anti-particle? I suppose that would apply to gravitons too... If gravitons exist, I am sure the anti-gravitons would be in the gravitational field of the anti-matter. No, anti-matter gravitates normally. But if there are gravitons... David A. Smith |

But if you had the photons synchronized to go together in the same direction, they would carry the gravitational field of our solar system with them? |

I don't associate gravity with gravitons, but rather spacetime with a kind of substance that is contracted by gravity, and according to this view, anti-gravity would simply be "stretching" of spacetime, rather than "contraction" of spacetime. |

"Center of momentum frame" implies that there are different momenta, that the photons are *absolutely not* directed all in the same direction. they would carry the gravitational field of our solar system with them? Until they passed any particular location. Imagine you were orbitting a massive object. Imagine you rigged the massive object to "blow" every bit of itself in every direction, all out past your orbit. Until some of the pieces passed your orbital radius, you would realize no change in your orbit. It can just happen faster if the "pieces" are photons. David A. Smith |

Quantum mechanics requires an actor to mediate gravity. This would be the graviton. So I guess the graviton could be its own anti-particle? Anyway, eventually a graviton will also have to model / mediate spacetime. How successfully... David A. Smith |

As to your "flavor", no telling how fast gravitational changes propagate. Generating a significant test is problematic. Gravitational effects from / by things we can annihilate are undetectable, except perhaps over centuries... David A. Smith |
