As far as I have been able to tell, all particles and all energy is effected by gravity (nothing (?) can escape from a black hole except by tunnelling maybe (not too probable), and nothing can pass through one, even neutrinos, etc, that I have heard of). So if "gravitons" really exist, and have energy/momentum because they're moving, how could they get out? Also, do particles emit a characteristic spectrum when they fall into a black hole? If so it would seem that you could determine the existence of arbitrary particles from the spectrums they emit falling into black holes (or neutron stars, or whatever). Just wonderin' james blasius ihps3!ihuxq!dopey
