The Hole in the Sky

"Here, it is believed, neither light nor dark matter can be found."

The light part is not quite true; what it says it that neither normal nor dark matter can be found, which is almost the same thing, but not quite.

I think the observations are correct, but the interpretations are not. We will have to see what 'light' other observations cast upon it, especially the Planck satellite.

Jorrie, with tongue-in-cheek, I propose that this is where the "Big Bang" explosive event occurred, and thus all matter and energy has been blown away, leaving the observed void. Another explanation could be a cloud of mini- or larger black holes, which have swept everything up. I assume that we can see more distant galaxies on "the other side" of this void...

hi Cardio-2 "I assume that we can see more distant galaxies on "the other side" of this void..."

For sure... The original attention was drawn to it because the CMB light that comes from way beyond is slightly cooler in that direction in the sky. AFAIK there are galaxies visible 'on the other side' from our point of view, just not many inside the void. Gravitational clumping has the effect of creating voids. It's just that this one is surprisingly big, if the observations are correct.

Damn the pornographers! I did a quick Google using some keywords in the National Geographic title.....And all I can say is "Damn the pornographers"!

Sorry. I meant to mark my previous comment off topic.
