IMHO, Dark Matter is just a side effect caused by Dark Energy!
Think of how rising dough/bread creates bubbles & (so) a web-like structure! & now imagine that, Dark Energy creates (keep growing) large bubbles of intergalactic voids & so the Cosmic Web!
(Imagine that, spacetime is a superfluid medium that made of (gas-like) virtual particles of quantum vacuum! & now imagine that, the Cosmic Web is made of denser spacetime superfluid (because of constant push from bubbles created by Dark Energy)!)
If you THINK, this view would easily explain:
Why there is no such thing as any kind of "Dark Matter Particle" to find!
Why a small percentage of galaxies appear to have no DM!
Why some galaxies could appear to have too much DM!
