August 30, 200718 yr I'm surprised no one has posted about this yet... Researchers at the University of Minnesota have found a giant hole in the universe. Basicly, they found an area of space that is about 1 billion light years across that is completely empty space, no black holes or even any dark matter exists in this space. Finding voids in the universe is apparently not unusual, and are usually caused by near large galaxies pulling all matter towards itself. However no "hole" has ever been even close to being as large as the one recently found. With a void this large, and with the knowledge that others are formed by gravity from nearby galaxies, one would expect supermassive galaxies lining the area of this void right? Well, those expectations are wrong, the discovered void sits in an area of space known as the "WMAP Cold Spot" named for its low levels of back ground radiation from the big bang. So then what have we found, could it possibly be the famed center of the universe? When a large bomb goes off, the epicenter is devoid of everything as the blastwaves spread out right? Well then couldn't this be the "empty hole in the ground" of the universe? All words are my own using reference from MSNBC: Hole in Universe -All sigs by me.[My Gallery]
August 30, 200718 yr I always thought the universe was shaped like a donut :-k What happens if you go in it? :-k Tbfgraphx14Happy to find I'm not the only one who eats glass.
August 30, 200718 yr Author I always thought the universe was shaped like a donut :-k What happens if you go in it? :-k According to the donut theory it is, but if there is a 5th dimension as the donut theory states, wouldn't a "bomb" or the singularity also expand into that dimension? And if by "go in it" you mean the middle of the donut? Well you can't, if you tried, you'd just return to the point of where you started. -All sigs by me.[My Gallery]
August 30, 200718 yr Now all we need is the Event Horizon to fold space and go visit this said "empty" region of the universe... :thumbsup:
August 30, 200718 yr Sounds spooky. I guess we'll just have to wait and see how this pans out or how they explain it.
August 30, 200718 yr I was under the impression that the universe had no center, as such. That it was just ever expanding in every direction. But I'm probably wrong. On another note, there's a porn ad above me. =\ Tip.it lowering its standards? Cool.
August 30, 200718 yr I was under the impression that the universe had no center, as such. That it was just ever expanding in every direction. But I'm probably wrong. Correct, the current Big Bang model has the Universe a bit like an expanding balloon. There is no preferred centre of the expansion. "Da mihi castitatem et continentam, sed noli modo"
August 30, 200718 yr completely empty space, Isn't that what space is anyway? Also isn't there a slight difference between a hole and a void? A void is surely just empty space and a hole suggests an actual physical tearing that one can move through, at least to me - space science is most definitely NOT my area of expertise. *waits for warrior to put it into stupid man talk for me*

Biology is more to my liking. The odd thing about this void seems to be it's scale - 1 billion light years across aparrantly. Bloody huge.
August 30, 200718 yr Seen it already on another board. The best reason I can come up with is that the astronomers found Azathoth. Varrock Library: Shattered Sky | Silent Thunder | The Emperor's FinestAstri @ MythWeavers
August 30, 200718 yr Like it says in the article, voids are pretty common. The universe is like fairy floss (cotton candy), there are a lot of stringy bits and holes with nothing in them.
August 30, 200718 yr Author Like it says in the article, voids are pretty common. The universe is like fairy floss (cotton candy), there are a lot of stringy bits and holes with nothing in them. Yes but as i mentioned, usually from large galaxies pulling all matter towards itself... Yes the universe is expanding in all directions, but if there was a big bang, it came from a singularity so there has to be one point from where all the expansion began, even though it might not be the point from where expansion continues. Am I right? Baron, space on a large scale contains something, whether it be galaxies or dark matter, this void contains nothing at all. Space on a small scale is as you said just empty space, but completely different on a large scale. -All sigs by me.[My Gallery]
August 30, 200718 yr As far as I know, After the big bang, there was only so much matter/anti matter created. I know of some instances where both are made randomly, but not in great amounts, so Logically as the universe expands, it cannot be filled with matter/anti matter as there isn't enough to go around.

Lemme point out that the void was about 6-8billion light years away from Earth, so its close pretty close to the beginning of the universe. -All sigs by me.[My Gallery]

Not really, As far as I know, the earth is relatively young compared to most other heavenly masses (Many stars older, I don't know how to tell the age of other planets), therefore meaning that it must be fairly far away from there.

August 30, 200718 yr Who cares? It's just a void! The centre of the universe would be some kind of core, not empty space. Just one long boring stretch of highway on the intergalactic scene. My heart is broken by the terrible loss I have sustained in my old friends and companions and my poor soldiers. Believe me, nothing except a battle lost can be half so melancholy as a battle won. -Sir Arthur Wellesley
August 30, 200718 yr How can they actually see that nothing is there? :-k By an absence of measured data I suppose.
August 30, 200718 yr Maybe they used some sort of doppler redshift (the thing that is used to see how far away galaxy's are).

Space on a small scale is as you said just empty space, but completely different on a large scale. See my post, the concept of a "centre of the universe" is false. It's misleading to compare it to an explosion from a single point in space, since the Universe is space. "Da mihi castitatem et continentam, sed noli modo"
August 30, 200718 yr What exactly is nothing? I mean say you had a glass with nothing in it (no drink or anything), it isnt empty because there is still air in it, but in space there is no air. So if you held the same cup in space, with no liquid or anything in it, there wont be air in it either, because there is no air in space, but there still must be something there, since as there is a place that you are talking about that is empty, but if you didnt hold the cup in that empty space, then there would be something in it, wouldnt there? :-k
August 30, 200718 yr It's heaven! It's heaven! Fonzie be praised! This is how much you all raised for charity. Thank you.
August 30, 200718 yr For once, Tip.Iter's are LITERALLY arguing about nothing. :mrgreen: ROFL! What exactly is nothing? I mean say you had a glass with nothing in it (no drink or anything), it isn't empty because there is still air in it, but in space there is no air. So if you held the same cup in space, with no liquid or anything in it, there won't be air in it either, because there is no air in space, but there still must be something there, since as there is a place that you are talking about that is empty, but if you didnt hold the cup in that empty space, then there would be something in it, wouldn't there? :-k There is nothing in the cup if you hold it out in space because the air gets sucked out. Scientists used to think that space was filled with something, but this was disproved. Empty space is entirely devoid of matter. Ah, this reminds me about the noob on the Runescape forums who was upset with the quest "Cold War" because apparently his grandparents died in the war. :wall:
