Another fascinating article, this time about light and the absence of it, and the potential for that absence.

I often wonder about the absence of energy. What if black holes aren't hot? What if black holes dissipate heat and are cold and absent of energy? What if absolute zero doesn't exist because as with heat or time or space you can always add a bit on, the same as infinity plus one is still infinity. 

I saw this article yesterday and was immediately struck by the fact that these guys have effectively created a definite absence at the periphery, where previously there was blur of bleed over. Straight away you can see how this can totally refine imagery (no pun intended), but beyond that, it opens the door on `what isn't', and where `what isn't' is ... there might be something paradoxical there ... that or I'm talking shit.
