Science a GoGo's Home Page Forums General Discussion Physics Forum Hole in Universe Found

Astronomers have found an enormous hole in the Universe, nearly a billion light-years across, empty of both normal matter such as stars, galaxies, and gas, and the mysterious, unseen "dark matter." While earlier studies have shown holes, or voids, in the large-scale structure of the Universe, this new discovery dwarfs them all.

Not only has no one ever found a void this big, but we never even expected to find one this size,"

...including the Press release.

***Thoughts
A billion light year across - void.
How?
1/The random distribution of matter during the Big Bang?
2/If so...should'nt there be as many high density areas, as low?
3/An evaporated Black hole?
4/A very old, or very new, part of the Universe?

All ideas open for discussion

Boy, that sure is a big hole! We mentioned Pioneer 10 in another thread. It would take Pioneer 10 about 2000 times the present age of the universe to cross that distance.

How could it be? Not a clue. Not the slightest

Thats a clever analogy on your part, to show its great size.

It seems that light received thru this hole is red shifted a little less than usual.
Which must mean that this 'hole' could not be expanding so much as the universe around it.

That's very interesting. If dark energy is real, then that region would seem be lacking in dark energy as well as everything else.
