If gravitons exist, then black holes do not, they couldn'tescape.

Jeff What if dark matter,and dark energy creates gravity,and not
regular matter. Dark matter I can relate to virtual photons as we now
theory as creating magnetics,and gravity and magnetize have one relative
mystery they can move objects without touching and over distance,also
both are invisible,but easily detected. Both come out of matter. These
thoughts enter my mind for this reason What could be darker than a
black hole? Reality is their is 93% more dark matter in the universe
than matter that is visible. That the intrinsic energy of space gives
off no photons. It is only virtual energy,and like virtual photons it
is 100% dark. Easy theory is Dark Energy has in this spacetime of the
universe creating such a strong gravitational force as to squeeze the
fusion force of stars evolving them into cold black dwarfs. Not to
worry the final black death of our universe is about 3 trillion years
