As you may remember, the internet is full of holes. As I've also said recently, mathematical equations and broad hypotheses do nothing as far as convincing me that ours is a computer-generated reality. Those scientists must really be working overtime to keep me up at night, however, because just this week they managed to stumble across some interesting new information about how very alike our universe and the internet (and perhaps even swiss cheese) truly are -- for the universe, too, is full of holes.
Astronomers have stumbled upon a tremendous hole in the universe. That's got them scratching their heads about what's just not there. The cosmic blank spot has no stray stars, no galaxies, no sucking black holes, not even mysterious dark matter. It is 1 billion light years across of nothing. That's an expanse of nearly 6 billion trillion miles of emptiness, a University of Minnesota team announced Thursday.
What the hell, right? Well, in the vaguest sense, this is not a new discovery; voids in space have been noted before. What makes this so surprising is that this particular void is exponentially more vast than anyone had previously imagined. Lawrence Rudnick and his team of astrophysicists working at the University of Minnesota have had their eye on this cold spot for a while, but only now have they pulled together years of data for a bigger and fuller picture.
"We already knew there was something different about this spot in the sky," Rudnick said. The region had been dubbed the "WMAP Cold Spot," because it stood out in a map of the Cosmic Microwave Background (CMB) radiation made by the Wilkinson Microwave Anisotopy Probe (WMAP) satellite, launched by NASA in 2001. The CMB, faint radio waves that are the remnant radiation from the Big Bang, is the earliest "baby picture" available of the Universe. Irregularities in the CMB show structures that existed only a few hundred thousand years after the Big Bang. The WMAP satellite measured temperature differences in the CMB that are only millionths of a degree. The cold region in Eridanus was discovered in 2004.
The verdict of all this new data, at this point, seems to be pretty much just a state of slack-jawed shock all around.
"This is 1,000 times the volume of what we sort of expected to see in terms of a typical void," said Rudnick, author of the paper that will be published in Astrophysical Journal. "It's not clear that we have the right word yet ... This is too much of a surprise."
The big question, of course, is: what does this mean? Mostly, never underestimate science, because the minute you think you know what's there, you get thrown a giant vortex or nothing. As far as a more basic standpoint, it's not yet entirely clear, but I'm sure the fine men and women studying this anomaly will be working hard to figure out what has caused such a rift in space and why. The most prevalent theory right now is that gravity from bigger surrounding structures has pulled all matter away into sort of a reverse-planetoid sphere of nothing. Alternate theory: The Great Gamer in the Sky got too fancy and ran out of Sim-dollars before he could finish filling up the universe. Hey, why not? At this rate, it's no less plausible than anything else.
This is totally rad. It means the big bang theory may very well totally be true. there ya, go religious nuts there's the center of the universe and where it's finally tearing apart from the big bang and will eventually contract to. Piss off. LOL that'd be so great.
Well, since I've mathematically determined that this is actually my personal simulation, I thought I'd mention. In the mid 90s I had a few years that I lost to drinking and "such". Hole problem solved.
so is it still there if we can see as far back as less than a millions years after the big bang? I mean to us it is still there, but physically has it not been filled with...something? Perhaps Snacks?
I figured I'd round out the pop culture references that started with "Holy Universe Batman" (although I think it ought to be "Holey" to avoid confusion, but who am I, right?)

What I want to know is: how far away it is, and how quickly it's expanding....
It is not known to be expanding. Although observations of it are extremely limited.
It is also 5 to 10 Billion light years away , so DON'T PANIC.
We do know that there is also another very,very much smaller one practically right next door. just 2 million light years away. Full of snacks indeed

Full of holes? I thought you were going to then add ASSholes...I guess I should stop reading the other stories.
I found this odd:
"This is 1,000 times the volume of what we sort of expected to see in terms of a typical void,"
How does void have volume?
Volume is not the measure of the contents of a space but a measure of the dimensions of that space.
For instance, a spherical balloon that measures 6" in diameter has the same volume whether it is filled with air, water or hypothetically, nothing at all.

Thanks. I slept through most of my physics classes in college!
All those stellar voids are where mankind set up home in ages past. We keep blowing ourselves up and the survivors move elsewhere... no, wait; that's my theory that we keep bouncing back and forth between Earth and Mars, ruining one planet while the other recovers.
Well then, maybe it was aliens who blew themselves up.
