Is the Eridanus Void a "Universe-in-Mass" Black Hole One-Billion Light Years Across? (Today's Most Popular)

Blackhole1 The apparent development of a large void of some billion light-years in diameter in the Constellation Eridanus appears to be improbable given current cosmological models. A radical and controversial theory proposes that it is a "universe-in-mass black hole" rather than hypothetical dark matter responsible for the phenomenon described as the expanding-accelerating universe.  This radical theory of cosmology suggests that stars at the edge of the Hubble length universe are being consumed by a universe-in-mass black hole.

In August of 2007, astronomers at the University of Minnesota located a gigantic hole in the universe. This empty space, stretching nearly a billion light-years across, is devoid of any matter such as galaxies, stars, and gas, and neither does it contain the strange and mysterious dark matter, which can be detected but not seen.

Empty places in the universe are not uncommon. It is already known that matter tends to clump and form stars and galaxies, clusters and superclusters, due to the pulling force of gravity. So astronomers have already seen places in the universe where there are groups of matter and places where matter is more scarce. But this new discovery is much larger than any previously known "hole".

“Not only has no one ever found a void this big, but we never even expected to find one this size,” explains Lawrence Rudnick of the University of Minnesota. Rudnick was one of the researchers to find the hole. 

Rudnick and his team studied data from a survey of the entire sky imaged by the Very Large Array radio telescope. A map of this area of the sky was already known to be an anomaly. It had been called a "cold spot" after a satellite that charts the cosmic microwave background radiation discovered it was less warm than its surroundings. (Overall the cosmic microwave background radiation is exceptionally cold, and the difference seen was only in millionths of a degree.)

The area of sky in which the hole exists lies in the direction of the constellation Eridanus. Eridanus is the constellation of the River, and can be found winding below Taurus and Cetus.

But the hole is not a part of the cosmic microwave background (CMB) radiation, which is a remnant of the Big Bang. The hole lies between six to 10 billion light-years away. The cold spot is a result of the CMB radition passing through this blank area on its way to Earth. Supporters of the standard model Big Bang theory say the region is colder because of dark energy.

Dark energy, which has yet to be verified, can be seen as the opposite of gravity. While gravity pulls matter together, dark energy is what is causing the universe to expand, and at an ever-increasing rate. When the radiation from the Big Bang passed through this void in the universe, it had less energy than the radiation that passed through normal regions of space. In a simplistic explanation, the radiation is given a boost when it nears the pull of matter such as galaxies, and dark energy allows the radiation to propel away from these areas without losing the boost when gravity would pull it back. The radiation passing through the empty space does not get the boost and the energy, therefore it is slightly colder.

A contrary theory proposed in The Journal of Cosmology suggests that our observable universe orbits a super-supermassive hole just as the stars of entire galaxies orbit and eventually are swallowed by the supermassive black holes at their center. Like the stars closest to the black hole at the center of the Milky Way galaxy which have a greater velocity than stars on the outer arms (where the Earth is located), stars at the edge of our known, Hubble-length universe, orbit one of these "universe-in-mass holes" at a greater velocity than those stars further away thus effecting the red shift and dimness of light and creating the illusion the universe is accelerating and exanding. 

The illusion of an "accelerating universe" is due to the gravitational effects of a universe-in-mass black hole at the edge of our Hubble length universe. Stars closest to the hole accelerate to their doom.

Galaxies, stars, planets, moons, molecules, atoms, and so on, are continually recreated and destroyed, and matter and energy, including hydrogen atoms, are continually recycled and reassembled via activities associated with "black holes" also known as graviton-holes, gravity holes, super massive black holes, galaxy-in-mass gravity holes, and universe-in-mass gravity holes, depending on their size and gravity-mass.

In an infinite universe, these galaxy-in-mass black holes become more massive yet and eventually consume all the galaxies which have been caught up by its increasing gravitational grip . Once all surrounding galaxies have been consumed, all that is left is a void, a galaxy-in-mass gravity-hole in the fabric of space-time surrounded by eternal night and empty space.

The billion-light-years across "Eridanus black hole" is typical of black holes which have the gravity-mass of millions of entire galaxies. The Eridanus black hole sits like a giant black spider in an ocean of nothingness, having swallowed up all surrounding galaxies, gas, and light, including radiation from the Cosmic Microwave Background. 

Based on an analysis of the NRAO VLA Sky Survey data, Rudnick and his team in fact discovered that there was a significant and rather remarkable absence of galaxies even in the distant space surrounding this hole, in the constellation of Eridanus. Thus, the billion-light-years across "Eridnus black hole" must have consumed the gravity-mass of millions of entire galaxies all of which have been collapsed and concentrated into the singularity of this super-galactic hole.

The billion-light-years across "Eridanus black hole" should not be considered unique or as something abnormally large. There appears to be a gravity-hole which may contain the collective mass of all the galaxies which populate a Hubble length universe and which sits just outside our known Hubble length universe; that is, just beyond that region of space which can be observed.

Elsewhere, Is the he VIRGOHI21 black hole an example of what happens when the gravitional mass of an entire galaxy comes to be bound up in the singularity of a single black hole which becomes a galactic orphan devoid of any stars but which would then begin to draw distant galaxies toward it? Stars and entire galaxies are recycled. Stars grow old and die, becoming white dwarfs, brown dwarfs and black holes (Hawking 1990), all of which eventually, in an infinite universe, are swallowed by the supermassive black hole at the galactic center which becomes even more massive in size until all stars, young and old, within its galaxy, disappear inside. 

VIRGOHI21 has swallowed all the stars of its galaxy and has the gravity of an entire galaxy, an estimated total mass of about 1/10th the Milky Way, ten times more dark matter than ordinary matter, and is surrounded by vast clouds of hydrogen. Because of its galaxy-in-mass gravity, VIRGOHI21 has pulled up to 2000 galaxies toward it, creating the Virgo Cluster. 

More recently, in March 2009, astronomers using the the 1.2-metre UK Schmidt Telescope in Australia published a paper which revealed the discovery of an even larger, 3.5- billion-year-wide void while undertaking the Six Degree Field Galaxy Survey in the southern hemisphere. Enormous cosmic voids and giant concentrations of matter have been observed in a new galaxy survey, one of the biggest completed so far. One of the voids is so large that it is difficult to explain where it came from.

Scientists are still analysing the new map, but a few features stand out immediately. The biggest concentration of matter seen by the survey is a previously known giant pileup of galaxies called the Shapley supercluster, which lies about 600 million light years from Earth.

The survey also found some enormous voids – regions of space that are relatively empty, including one that is about 3.5 billion light years across.

"This is as big as I've ever seen," survey team member John Huchra of the Harvard-Smithsonian Center for Astrophysics told New Scientist.

Dang! That's neat!

Wow! So our entire Universe could be spinning around a Universe-in-mass black hole and that explains the acceleration and expainsion of the Universe? Holy shit that is cool!

Now if we could only get the general public to understand that we are living in the golden age of cosmology. I guess thats what happens when your head is buried in a bible during the day and eyeballs glued to American Idol at night.

nepharous, It's sad how literal your description was when compared to my family. :x

I have had a similar idea a long time ago, but I am not sure if it is even possible. A black hole of this size could and would be drawing all matter practically everywhere towards it, although science is always making the impossible-possible.

As for universe orbiting a ultra supermassive black hole. This would make since as everything in nature seems to point to a spin of some kind.
Electrons orbit protons.
Earth orbits Sun
Hell, the Sun orbits the milky way, so why stop there.

If true, i just hope they are ready to recalculate the age of the universe because this would mean that our universe is far older than we even dreamed of.

This sounds like a really cool idea. But its interesting because they mention nothing about any evidence that this gaps are "black holes" or not. IF they were, wouldn't they be emitting some kind of radiation that is detectable? I believe that black holes can be detected this way, but then maybe they are so massive that what we are observing doesn't fit into our mode of thinking currently.
But ideas like these are essential to the advancement of science, even if they are wrong in the end--because it gets people thinking outside of the normal mode of thinking.

not sure I understand how and object (even a universe-size-blackhole) can make our universe expend simultaneously in all directions. Even if we assume both are at about the same size (our universe and this black hole), they would rotate each other in circle, but it wouldn't push the side that's facing away even further. At least that's what ordinary gravity teaches us, right... ?

Nepharous, It is an amazing image. I get the bible and american idol references. My family would say it's the devil that put all that stuff up there to lure in suspected sinners. God created the stars only for us to see at night. That's it. Case closed. I swear you can hear their minds snapping shut from the sidewalk. Cheers, J

I thought there was a limit to how big a black hole could be?

they don't know shit, all speculation with flawed mathamatics

...so essentially, we're circling the drain.

and what is the cmb then?and maybe are voids greater after 14 bln light years that don`t let light travel,gaps of 50+ bln light years maybe.

I agree with Triffid - they know nothing. it's all based on big bang compost. The 'experts' have it all wrong - that's why they are always 'surprised' at research results.

It would be helpful to include in a caption that the picture is a stock image of an artists' impression of a generic black hole, not a picture of the phenomenon itself. It implies falsely that the phenomenon is that clearly observed.

@storm--being surprised at research results is how knowledge is gained... understanding is not an on-off switch, it's not like scientists don't "get it" and keep screwing up their theories. They have incomplete knowledge and base theories on what they know. It's not surprising that on the cutting edge of cosmology there are more unknowns than knowns.

maybe thats the center of the universe.

Tim - if the experts theories and models were correct or even remotely close, there would be little surprise because they would have a good idea what to expect, so I can not agree with you. My beef is with these ppl throwing around these theories like they are facts.

Just imagine someone saying Einstein was wrong? One can imagine the ridicule they would suffer. No funding or instrument time for you.

Until unification, we don't really know anything.

Dirk Alan:

If somebody say Einstein is wrong, yes they will be ridiculed and labelled as pseudo scientist's. But if that somebody has evidence to back he's claims then, he will surely face some opposition from some individual, but the scientific community will show little opposition. In science are the evidence that count's not the claims.

About the universe, we know alot, not everything but we know enough to know what is likely and what's unlikely. That big black whole the media article reports are highly unlikely.

ooOops HOLE not WHOLE...lol

lol at people jumping on religion when a scientific post comes out...don't remember it saying gravity doesn't exist or that light travels at the speed of God allowing you to see it...sigh. As to the article. If light travels at a constant speed and the universe is "expanding", why can't these dark spots just be light that hasn't travelled to a viewable range yet? If we are all being sucked into a massive central black hole…why do people think the universe is constantly expanding? Maybe two massive black holes on opposite sides are pulling us away from other universes? All in all I doubt a giant explosion from nothingness makes much sense…why did nothingness exist to begin with…who made God…it’s all the same question being pointed at everyone.

I don't know about anyone else (except ioannes) but when I read that it makes me think of a toilet flushing.... spinning around and around a black hole until we go down the drain.

Granted its the longest toilet flush ever.

Since when is dark matter "detectable"? Sounds like someone needs a little more fact checking.

Neo, I would guess that the "general public" knows less about the Bible than they do about science. Also, don't assume that anyone who studies the Bible watches nonsense like "American Idol", obviously I am interested in science and cosmology as well as Scripture or I wouldn't have read both this article and your response. What amazes me is so many people are interested in creation but offended at the thought of a Creator. It's easy to say everything came from nothing, but it is not logical. You see a watch; you know there is a watchmaker, a painting; a painter, etc. The universe shows a highly complex design; that would suggest a Designer. It is sad that nearly every science article's discussion page turns into a battle of science vs. religion. A universal negative cannot be proven, just because one thinks God does not exist does not make it so, and many scientists are Christians. I would suggest going online and reading a good Bible commentary, before assuming it's all nonsense. You might learn not all people of faith are lunatics, (or goofy t.v. show viewers): maybe we are just curious about existence on more than one level.

@ UyeahU

The burden of proof lies on the person who posits the belief. (ie. It's not our job to prove god doesn't exist, it's yours to prove it does. And as it stands, there's no prove whatsoever.)

Complexity comes from compounding outcomes of probabilities, it DOES NOT imply a creator. Just because you can't wrap your head around science doesn't mean it's illogical.

If 'people of faith' stopped acting like lunatics, then they'd cease to be stereotyped as lunatics. But the 'faith' part implies lunacy.

UyeahU: "many scientists are Christians." absolutely incorrect.

The higher someone's intelligence/IQ, the more likely they are to be atheist/agnostic.

There is no god. Get over it. To think the universe was purposely created by a sentient being just for us is laughably egotistical.

Scientists are overwhelmingly atheist/agnostic.
