Scientists recently discovered a huge void in the universe where there is nothing not even background radiation how big is this hole try one billion light years across.
I was interested in hearing what you guys have to say on the subject.:)

I read about that, but enough isn't known yet. So far it poses more questions than it answers.

Whoa whoa whoa, slow down a little. There IS CMBR there, it's just slightly colder than most other places, and there ARE stars and galaxies there, there are just less than in most other places.

Remember that we're seeing the hole as it looked 6-10 billion years ago i.e. in the beginning stages of our universe. So we don't know what it looks like now. Here's a pic of it:

Cap, You wow me...

Wherever did you find that pic?

It's everywhere :o

Hmm, the cold spot in the CMB could be because of the void. As the CMB travels through the void, the Sachs-Wolfe effect would come into play. Because the area is a void, the CMB would be expected to appear colder in that region for this reason.

So, the cold spot in the CMB is not an intrinsic property of the void, it's just that the CMB is altered as it passes through the void.
