Sitting in church and listening to a  sermon, I started
thinking about physics...

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'
