Well astronomers and scientists have seen holes before, but not one like this. This "hole" is 1 billion light years across. Imagine the size of that in regular miles. There are no stars, no black holes, no galaxies, or planets. There is not much matter at all, if any. Scientists say it is probably due to great amounts of gravity pulling from larger areas which will pull structures ouf of the less dense area, but to be this big? Kind of wierd to be looking in space and then all of a sudden you see an area of nothingness. I thought it was pretty cool. I don't know what exactly they may be able to benefit out of this but it could help us better expand the universe we live in.

The sheer size of this discovery in both size and impact could have a huge impact on the field is science. The exact reason why NOTHING is there will possible reveal a lot about the creation of the universe. The unnverving part is how massive this nothingness is. Cosmic background radiation is supposed to echo out everywhere from the big bang, but the fact it's a cold spot would mean this area was untouched even then. This is not only confusing and unsettling, but amazing.

Woow! a huge expanse of nothingness. Just wondering, would anything ever accumulate into this kinda extremely large space?
i would say if this vast space of nothingness, if not getting larger, is probably getting smaller. it is probably a big hunk of dark matter that is pulling all of the universe closer to itself. and i am sure your god had nothing to do with it.

Yeah I saw this article to and what I found funny is that Star Trek: TNG and I think Voyager had episodes loosely based on it., and I have to say that I am amazed something like this actually exists. What I find interesting and although I doubt this is true at all but you could say thats what the inside of a black hole looks like except for the huge amount of gravity that's inside of them.
I was browsing around and I found this picture of what the team believes it looks like and how it would be done:

The article goes into some more detail then the one on yahoo, but what I find interesting even more that there are severals voids in our know universe and no one really has talked about them until this big boy was discovered. So far it has been an interesting year for the universe with discoveries, disappointments (pluto being knocked). I wonder what 2008 will have in store for about knowing our universe just a bit more.

llustration of the effect of intervening matter in the cosmos on the cosmic microwave background (CMB). On the right, the CMB is released shortly after the Big Bang, with tiny ripples in temperature due to fluctuations in the early Universe. As this radiation traverses the Universe, filled with a web of galaxies, clusters, superclusters and voids, it experiences slight perturbations. In the direction of the giant newly-discovered void, the WMAP satellite (top left) sees a cold spot, while the VLA (bottom left) sees fewer radio galaxies. (Credit: Bill Saxton, NRAO/AUI/NSF, NASA)

It's amazing how we can be so intrigued by nothing. LOL. But yes, this is a very amazing discovery and it brings up lots of questions. I just want to know all the answers now, but we won't really know for hundreds or thousands of years - or maybe more. The universe is very vast and very interesting. There is so much that we don't know about.
