Is dark matter dark?

A box containing light is slightly heavier than a box containing no light. While I'm not the first to figure this out chronologically, my insight was independent.

Dark matter goes the way of phlogiston. Here is the same statement soft-pedaled. I read this first. All Hail Cal Tech!

"We had thought before that perhaps our understanding of dark matter was incorrect in these simulations, but these new results show we don't have to tinker with dark matter," says team leader Andrew Wetzel. "When we more precisely model supernovae, we get the right answer."

to be more precise, state radiation... but you know scientific theory doesn't go anywhere without popularism.

If the box is light, how can it be heavier than a box that is not light ?

....puns aside, photons have no mass, so why is light heavy.

One thing at least is certain, LIGHT has WEIGHT,
One thing is certain, and the rest debate —
Light-rays, when near the Sun, DO NOT GO STRAIGHT."

dark matter chewed on the lightbox, making it heavy dim light, and then the final hip hop death of light.
