Astronomers using data from NASA's Hubble Telescope have observed what appears to be a clump of dark matter left behind from a wreck between massive clusters of galaxies. The result could challenge current theories about dark matter that predict galaxies should be anchored to the invisible substance even during the shock of a collision...............

........... The team proposed numerous explanations for the findings, but each is unsettling for astronomers.

awwwwwwwww

Let's see, luminosity directly associated with dark matter?! :?

I think i am beginning to understand. If it is dark there is no dark matter, but if it is luminous, dark matter lurks nearby!

Plasma discharges have different modes: ARC , oh, my favorite! Glowing. Nice and peaceful.. And DARK. Dark means non-luminous, but there is still a discharge in the process. If all of the DARK mode plasma were to ramp up to ARC mode, this would be a very exciting universe.

I think we can safely assume that the luminosity near dark matter is plasma in glow mode...

In volume, 99.999% of all the observable matter in the universe exists in the plasma state. This had led to the coinage of the term "Plasma Universe."
