"Other Universes are Pulling on Our Universe" -- New Planck Data Triggers Controversy (Today's Most Popular)

 

R-OLDEST-GALAXY-large570


Is our universe merely one of billions? Evidence of the existence of 'multiverse' revealed for the first time by a cosmic map of background radiation data gathered by Planck telescope. The first 'hard evidence' that other universes exist has been claimed to have been found by cosmologists studying new Planck data released this past June. They have concluded that it shows anomalies that can only have been caused by the gravitational pull of other universes.

"Such ideas may sound wacky now, just like the Big Bang theory did three generations ago," says George Efstathiou, professor of astrophysics at Cambridge University."But then we got evidence and now it has changed the whole way we think about the universe."

Scientists had predicted that it should be evenly distributed, but the map shows a stronger concentration in the south half of the sky and a 'cold spot' that cannot be explained by current understanding of physics. Laura Mersini-Houghton, theoretical physicist at the University of North Carolina at Chapel Hill, and Richard Holman, professor at Carnegie Mellon University, predicted that anomalies in radiation existed and were caused by the pull from other universes in 2005. Mersini-Houghton will be in Britain soon promoting this theory and, we expect, the hard evidence at the Hay Festival on May 31 and at Oxford on June 11.

Dr Mersini-Houghton believes her hypothesis has been proven from the Planck data that data has been used to create a map of light from when the universe was just 380,000 years old. "These anomalies were caused by other universes pulling on our universe as it formed during the Big Bang," she says. "They are the first hard evidence for the existence of other universes that we have seen."

Columbia University mathematician Peter Woit writes in his blog, Not Even Wrong, that in recent years there have been many claims made for “evidence” of a multiverse, supposedly found in the CMB data. "Such claims often came with the remark that the Planck CMB data would convincingly decide the matter. When the Planck data was released two months ago, I looked through the press coverage and through the Planck papers for any sign of news about what the new data said about these multiverse evidence claims. There was very little there; possibly the Planck scientists found these claims to be so outlandish that it wasn’t worth the time to look into what the new data had to say about them.

"One exception," Woit adds, "was this paper, where Planck looked for evidence of 'dark flow'. They found nothing, and a New Scientist article summarized the situation: 'The Planck team’s paper appears to rule out the claims of Kashlinsky and collaborators,' says David Spergel of Princeton University, who was not involved in the work. If there is no dark flow, there is no need for exotic explanations for it, such as other universes, says Planck team member Elena Pierpaoli at the University of Southern California, Los Angeles. “You don’t have to think of alternatives.'"

"Dark Flow" sounds like a new SciFi Channel series. It's not! The dark flow is controversial because the distribution of matter in the observed universe cannot account for it. Its existence suggests that some structure beyond the visible universe -- outside our "horizon" -- is pulling on matter in our vicinity.

Back in the Middle Ages, maps showed terrifying images of sea dragons at the boundaries of the known world. Today, scientists have observed strange new motion at the very limits of the known universe - kind of where you'd expect to find new things, but they still didn't expect this. A huge swath of galactic clusters seem to be heading to a cosmic hotspot and nobody knows why.

Cosmologists regard the microwave background -- a flash of light emitted 380,000 years after the universe formed -- as the ultimate cosmic reference frame. Relative to it, all large-scale motion should show no preferred direction. A 2010 study tracked the mysterious cosmic 'dark flow' to twice the distance originally reported. The study was led by Alexander Kashlinsky at NASA's Goddard Space Flight Center in Greenbelt, Maryland.

"This is not something we set out to find, but we cannot make it go away," Kashlinsky said. "Now we see that it persists to much greater distances - as far as 2.5 billion light-years away," he added.

Dark flow describes a possible non-random component of the peculiar velocity of galaxy clusters. The actual measured velocity is the sum of the velocity predicted by Hubble's Law plus a small and unexplained (or dark) velocity flowing in a common direction. According to standard cosmological models, the motion of galaxy clusters with respect to the cosmic microwave background should be randomly distributed in all directions. However, analyzing the three-year WMAP data using the kinematic Sunyaev-Zel'dovich effect, the authors of the study found evidence of a "surprisingly coherent" 600–1000 km/s flow of clusters toward a 20-degree patch of sky between the constellations of Centaurus and Vela.

The clusters appear to be moving along a line extending from our solar system toward Centaurus/Hydra, but the direction of this motion is less certain. Evidence indicates that the clusters are headed outward along this path, away from Earth, but the team cannot yet rule out the opposite flow.

"We detect motion along this axis, but right now our data cannot state as strongly as we'd like whether the clusters are coming or going," Kashlinsky said.

The unexplained motion has hundreds of millions of stars dashing towards a certain part of the sky at over eight hundred kilometers per second. Not much speed in cosmic terms, but the preferred direction certainly is: most cosmological models have things moving in all directions equally at the extreme edges of the universe. Something that could make things aim for a specific spot on such a massive scale hasn't been imagined before. The scientists are keeping to the proven astrophysical strategy of calling anything they don't understand "dark", terming the odd motion a "dark flow".

A black hole can't explain the observations - objects would accelerate into the hole, while the NASA scientists see constant motion over a vast expanse of a billion light-years. You have no idea how big that is. This is giant on a scale where it's not just that we can't see what's doing it; it's that the entire makeup of the universe as we understand it can't be right if this is happening.

The hot X-ray-emitting gas within a galaxy cluster scatters photons from the cosmic microwave background (CMB). Because galaxy clusters don't precisely follow the expansion of space, the wavelengths of scattered photons change in a way that reflects each cluster's individual motion.

This results in a minute shift of the microwave background's temperature in the cluster's direction. The change, which astronomers call the kinematic Sunyaev-Zel'dovich (KSZ) effect, is so small that it has never been observed in a single galaxy cluster.

But in 2000, Kashlinsky, working with Fernando Atrio-Barandela at the University of Salamanca, Spain, demonstrated that it was possible to tease the subtle signal out of the measurement noise by studying large numbers of clusters.

In 2008, armed with a catalog of 700 clusters assembled by Harald Ebeling at the University of Hawaii and Dale Kocevski, now at the University of California, Santa Cruz, the researchers applied the technique to the three-year WMAP data release. That's when the mystery motion first came to light.

The new study builds on the previous one by using the five-year results from WMAP and by doubling the number of galaxy clusters.

"It takes, on average, about an hour of telescope time to measure the distance to each cluster we work with, not to mention the years required to find these systems in the first place," Ebeling said. "This is a project requiring considerable followthrough."

According to Atrio-Barandela, who has focused on understanding the possible errors in the team's analysis, the new study provides much stronger evidence that the dark flow is real. For example, the brightest clusters at X-ray wavelengths hold the greatest amount of hot gas to distort CMB photons. "When processed, these same clusters also display the strongest KSZ signature -- unlikely if the dark flow were merely a statistical fluke," he said.

In addition, the team, which now also includes Alastair Edge at the University of Durham, England, sorted the cluster catalog into four "slices" representing different distance ranges. They then examined the preferred flow direction for the clusters within each slice. While the size and exact position of this direction display some variation, the overall trends among the slices exhibit remarkable agreement.

The researchers are currently working to expand their cluster catalog in order to track the dark flow to about twice the current distance. Improved modeling of hot gas within the galaxy clusters will help refine the speed, axis, and direction of motion.

Future plans call for testing the findings against newer data released from the WMAP project and the European Space Agency's Planck mission, which is also currently mapping the microwave background.

Which is fantastic! Such discoveries force a whole new set of ideas onto the table which, even if they turn out to be wrong, are the greatest ways to advance science and our understanding of everything. One explanation that's already been offered is that our universe underwent a period of hyper-inflation early in its existence, and everything we think of as the vast and infinite universe is actually a small corner under the sofa of the real expanse of reality. Which would be an amazing, if humbling, discovery.

The image at the top of the page shows the most distant object we have ever observed with high confidence, according to Wei Zheng, the leading astronomer of the team at Johns Hopkins University who that noticed the galaxy on multiple images from both the Hubble and Spitzer space telescopes. At 13.2-billion years old, we are technically seeing this galaxy when it was very young, but its light is only reaching Earth now.

What next? Dark horizons?

"Look behind you." - Universal centre? A hole so big the gradient is negligible between us and the flow point, the time and the acceleration increase?

whats funny im50 and knew there was more than one of everything . the question is, how big is our univers , and how big are the others,, and I think that , there is life out there , even tho , the planet can not let live like we do here, life revoles around many different ways , my pc is acting up

I remember reading, some time ago, that distant galaxies were accelerating away from us. At the time the speculation was that dark matter was causing this. At the time, I asked whether there was any possibility that these galaxies were being drawn to something, rather than being pushed. I wonder if these new "findings" suggest that that might be the case.

I agree with Jim Poulsen ^ Push or pull?

It's very hard to tell from this account whether the consensus is for or against the hypothesis of Dark Flow. The scientific paper by the Planck scientists is at
http://arxiv.org/abs/1303.5090
where no less than 175 scientists conclude "There is no detection of bulk flow," a great big, giant negative for the Dark Flow hypothesis.

A very intriguing article. That most astronomers disagree with Kashlinsky is not at all surprising. This cannot be taken to mean he's wrong, at least, not at this point. The onus is now on he and his team to validate their claims. It took ~60 years for plate tectonics to be accepted so I won't look for this to be decided quickly.

i vote ‘dark flow’ because it’s nicer to think about newer and farther horizons and fractal infinitudes. With that settled, hopefully, we can focus on preserving and bettering our precious gift of life (as we know it now).

I wonder if an unknown and growing black hole located between here and there could be creating a localized lens effect that would make distant background galaxies appear to be moving towards a point or in a direction. The black hole would presumably be very hot and visible unless it was somehow masked, like by a giant gas cloud or other aligned galaxy. Just thinking out loud...

so what is the great attractor?

is it possible this is an entrance to another universe?

If the big bang predicts an even CMB, and it is heavier on one side, shouldn't wr consider the possibility the CMB is not a consequence of the big bang?

The great attractor is likely a polar opposite of the big bang. Something so dense and void of light that we cannot even detect it but only through its pull on the universe we observe. Are galaxies truly expanding apart? I think these proposed dark matter experiments are going to shock the physics world, by confirming it's non-existence. Forcing us to think way outside the box.

In the book, «From the inside of quarks and up to beyond the Universe», you will find too many theoretical data, related to the subject of this article.

Everything theorized today stems from a single source...Einstein
Einstein's theories have all been thoroughly debunked...
google or youtube debunk Einstein

Russellian Science is the best explanation of everything so far involving physics and the cosmos.

see: 77gslinger, theory of anti relativity, theRealVerbz, debunk Einstein.(extremely short list)

P.S.
Planck's constant=debunked

They cannot even see what is behind and beneath, but they talk about whole galaxy, other galaxies, and even other universes. This is all whole sh*t.

(im)pure guesswork. Open The Pleiadian Mission by Randolph Winters and learn what a race 12,500 years ahead of us on tech know about Universes.

Before you scream hoax, if this information upsets you because it didn't come from nasa, seti, astronomers or the Govt., consider that data on our solar system was published sometimes years ahead of nasa's discoveries by Swiss contactee Meier. That either given him by et or from his personal observation from their craft. www.theyfly.com is the Meier site, Winters books refers to these contacts.

By definition, there can be only one "Universe." There may be other facets to this one, however. Maybe we need a new term (galaxy congregations?) between galaxies and the Big U.

There can be only one universe IMO. Even if there was a multi-verse, it doesn't make sense for other universes to affect our universe. It's supposed to be independent. So they detect some unified motion relative to the CMB. Doesn't mean there's a whole other universe pulling.

Geesh, what happened to simple science and Ockham's razor?

The super advanced beings in the much older universe near ours are sucking matter out of our universe to keep theirs alive!

I agree with Robert when he said there can only be one universe by its definition. What we can see now is just a part of something much bigger that we don't see or understand yet. When people hypothesize about the past and future of the universe they can be sure that the truth is more fantastic than they can ever imagine.

Think about civilization billions of years ahead us.
They are very concerned that universe is expanding, so in next trillion or so years they will run out of material for expansion (red dwarfs start to die also)

So they decide to make great attractor to pull together some of the galaxy clusters to have enough room to live for next trillions of trillions of years by making new stars from combined clusters :-p

If the other universe is pulling then why is it called other? Are they coupled like two Galaxies. What am I missing?

Be careful of travelling to edge of the universe, the dragons Huva and Lectrolux will blow you over the edge. Our universe along with many others combined might possibly form an atom in another (here I need help with using the right term) space, place, dimensi n? No these don't really do the trick. I am unable to explain this line of thought, let imagination be the source. Just thinking aloud, I trust that is allowed?

Other Universes are not pulling on matter in our Universe.

Our Universe is a larger version of a black hole polar jet.

Once a person reads the cases of George Adamski and Valiant Thor and Phil Schneider , he/she won't think the same way about the universe.
