Avriette A black hole is not really part of the universe,but the
accretion disk it creates is. The accretion disk is made from a star
that got to close to a black hole,and most of its material is spiralling
in. The force of angular motion ,and the black holes force of gravity at
a distance creates this disk of moving particles,and energy. Some of
this disk is radiated out into space,but most of it reaches the event
horizon close to the speed of light. Once hitting the black holes
surface it is lost from the universe,and adds to the mass density of the
black hole. My image of the disk has it looking like a question mark ?
and the dot on the bottom is the black hole. Lots can be learned from
this accretion shaped question mark;. Reality is its like
looking at the big bang in reverse. Gravity created the stars,and
gravity is showing us it can remove what it has created Bert
