Interesting links, DW.=Dreamwoven;1343353]I've been struggling to understand the dark energy debate. Gravitational waves (https://en.wikipedia.org/wiki/Gravitational_wave) and Black holes (https://en.wikipedia.org/wiki/Black_hole) are clearly connected. Black holes form as a result. As I see it, this means that black holes function as a sort of rubbish bin that can dispose of matter (like stars at the end of their lives when they become red dwarf stars?).
Neither are the astronomers themselves it seems:I'm not at home at this level of debate (though we all probably feel the same way) but perhaps we will learn more as time goes on.
"Dark energy is usually assumed to form roughly 70% of the present material content of the universe. However, this mysterious quantity is essentially a place-holder for unknown physics."
