Author | Topic: The Big Nothing | |||||||||||||||||||||||||

I would like to see a discussion centered on what the discovery of the huge hole in the universe means to our understanding of things.
The Big Nothing I'm not sure where it should go as I have no point to make. I just want to ask the question.

Buzsaw was trying to make some sort of philosophical discussion based on this discovery. His "Proposed New Topic" (PNT) New Discovery: Giant Empty Space In Orion was ultimately withdrawn/rejected. In message 23 there, I provided a couple of other links to the story:
http://www.canada.com/edmontonjournal/news/... http://www.theaustralian.news.com.au/story/... If this is indeed such a big mystery to the astronomers, I highly doubt we're going to solve it here. But I will promote it. Adminnemooseus New Members should start HERE to get an understanding of what makes great posts.

Space.com has a good writeup on it. One thing to note is that it is NOT empty, but rather "mostly devoid of stars, gas and other normal matter, and it's also strangely empty of the mysterious 'dark matter' that permeates the cosmos" in the words of the Space.com article.
It is also not the only such area but rather just the biggest found so far, and it shows a drop in the expected distribution, not a total absence. It had been noted before, appearing as a vast cold spot on the WMAP. Likely we will learn more about it, and what we learn will certainly tell us more about how the Universe developed.

It is 1000 times bigger than other similar voids found in the past. One researcher says that it certainly needs to be examined and taken seriously and not simply ignored or written off as an anomaly.
The universe is so darn big that the time and money needed to explore it won't allow us to understand it anytime soon. I wish we just knew everything! Its frustrating to learn about things so slowly!

Hi Jar
Thanks for the link. I remember reading that you could be anywhere in the universe and looking up in the sky would look the same as anywhere else. It now appearts that isn't correct. Does this do anything to the Big Bang theory as it appears that the expansion is very uneven? I suppose this is just another piece of the puzzle. Everybody is entitled to my opinion.

Best ask someone like CaveDiver who would know quite a bit more but I would doubt it. First, this is long, long after the BB and one thing that was clear from WMAP is that things were never very uniform. If you look at some of the images from WMAP you'll see that things were pretty chaotic, and lots of stuff going on. There were hotter and colder areas, various polarizations, lots of movement.
But remember we are JUST starting to analyze the data we've gathered. WMAP was not even launched until 2001 so we are very early in the learning cycle and it has already contributed enormous volumes of data, speculation and research. Aslan is not a Tame Lion

I found a few other links related to the various voids that have been mapped.
This is a link to some of the earlier material And today's APOD was on the most recent.
Direct link only for 08-27-07 After that date you will have to search by date. One interesting point is :
The void is not a hole in space like a black hole, but rather a vast region of the universe that appears to be mostly devoid of normal matter and even dark matter. The void is still thought to contain dark energy, though, and is clearly traversable by light. so as mentioned in an earlier message, it is certainly not empty. Aslan is not a Tame Lion

When is this void?
It appears to be about 6-10 billion light years from Earth and early estimates seem to say it is about a billion light years across. Aslan is not a Tame Lion |

This hole represents the ignorance of western civilization. As does the solar eclipse befuddle the arrogance of our intellectuals. Maybe the astrologers forgot to wipe off the lenses?

While it's nice that you're supplying a creationist side view all over the place, how about some quality in your messages?
...astrologers... That would be "astronomers". Adminnemooseus New Members should start HERE to get an understanding of what makes great posts. Comments on moderation procedures (or wish to respond to admin messages)? - Go to:

From wikipedia:
At this time astrology and astronomy were not distinguished as separate disciplines; the act of astronomical observation was often done by someone who had astrological motives for doing so. Indeed, astrologers' professional responsibility and desire for predictive knowledge for a large part spurred the advancement of astronomy, and the Babylonians developed a very precise ability to mathematically predict the location of celestial points and phenomena based upon their observable cycles. Astrology - Wikipedia I apologize if I was being facetious. Although, I intended that to be my contribution of a hypothesis. Is there certain rules about replying to admins? I don't want to break anymore rules.

I'm sorry, perhaps I'm just a moron. I just don't understand what point you're trying to get across and what it has to do with the topic of the thread.
