<<When a slime mold mass or mound is physically separated, the cells find their way back to re-unite. Studies on Physarum have even shown an ability to learn and predict periodic unfavorable conditions in laboratory experiments. John Tyler Bonner, a professor of ecology known for his studies of slime molds, argues that they are "no more than a bag of amoebae encased in a thin slime sheath, yet they manage to have various behaviours that are equal to those of animals who possess muscles and nerves with ganglia – that is, simple brains."

Atsushi Tero of Hokkaido University grew the slime mold Physarum polycephalum in a flat wet dish, placing the mold in a central position representing Tokyo and oat flakes surrounding it corresponding to the locations of other major cities in the Greater Tokyo Area. As Physarum avoids bright light, light was used to simulate mountains, water and other obstacles in the dish. The mold first densely filled the space with plasmodia, then thinned the network to focus on efficiently connected branches. The network strikingly resembled Tokyo's rail system.>>

It seems appropriate on Hallowe'en to show that Dark really matters.

Just imagine...
In the "Dark Matter Universe", with DM planets and people, they look at their "Bright Matter Universe" Simulation, and WONDER....

Is it correct to say that the dark matter is coalescing near and literally connecting the baryonic matter? and is acting like a 'sheath' of some sort? It looks like the 'fibers' of dark matter are also connecting the galaxies and clusters as if they are being held together in by some kind of gravitational or magnetic pull? Wouldn't this go against the stance (most) Dark Matter doesn't interact with baryonic matter?
Obviously I don't understand any of this but thanks to this picture and forum I can throw ideas out there.

hmmm, the speed of darkness is the same as the speed of light

Dark Matter does interact with baryonic matter gravitationally.
Dark Matter may interact with baryonic matter through the weak force.
Dark Matter may interact with itself through some other mysterious long and/or short distance forces.
