> It somehow feels more appropriate to me to think of dark energy as energy being extracted out of the universe, in some form never to return. Maybe like a black hole evaporating as observed from the inside?
But in this story the black hole increases in size as matter falls into the horizon and shrinks as it evaporates, so cosmic expansion would be associated with more energy falling into the black hole than leaving it.
I thought about this part. I'm not sure we can link apparent size from outside the event horizon to apparent size from inside.
Apparent distance is something that's affected by relative frames of reference and the frames of reference are as different as as can be in this case.
