Is the reaction in the Universe which causes dark energy the outflow of a Universal black hole, causing the galxy clusters to accelerate away from us?
Ah, I see. And what about dark matter? Are the two related in any way?
While dark matter and dark energy both account for a significant portion of the universe, they are thought to be distinct phenomena. Dark matter is believed to be an invisible type of matter that interacts with visible matter only through gravity, whereas dark energy is a force that opposes gravity and is responsible for the accelerating expansion of the universe.
