EBarnacle 'dark energy' is something entirely different regarding accelerating expansion forces as you know. That more volumetric space is being produced is quite a mystery to be sure. The possible dark balancing act going on is a mind blower. We wouldn't want to stretch the universe to its tearing point would we? Some say the entire universe will have to drop to a lower energy state which will be like a big rip. They claim it is inevitable.

C'est la guerre.
