"Buraco negro" no Atlântico sul?
E satélites captam fenómeno, que não era conhecido antes, de sucção de água do oceano Atlântico que os físicos dizem ter mesma dinâmica que "buracos negros" astronómicos.

Black Hole Analogue Discovered in South Atlantic Ocean
Vortices in the South Atlantic are mathematically equivalent to black holes, say physicists, an idea that could lead to new ways of understanding how currents transport oil and garbage across oceans
Black holes are regions of spacetime in which gravity is strong enough to prevent anything escaping, even light. These strange objects were first discovered in the early 20th century as mathematical solutions to the equations of general relativity. (It was not until much later that astronomers began to gather observational evidence of their existence.). One of the curious features of general relativity is that the same mathematics crops up in various other situations. In recent years, for example, physicists have worked out how to create invisibility cloaks by steering light around objects using metamaterials.
Black holes steer light in the same way by bending space-time. In fact, the mathematics that describe both systems are formally equivalent. Because of that, it should come as no surprise that engineers have used metamaterials to create analogues of black holes that prevent light escaping.
Today, George Haller at the Swiss Federal Institute of Technology in Zürich and Francisco Beron-Vera at the University of Miami in Florida have found another analogue of a black hole, this time in the world of turbulence.
The vortices that can form in turbulent water are a familiar sight. Edgar Allan Poe described just such a whirlpool in his short story “A Descent into a Maelstrom” which he published in 1841:
“The edge of the whirl was represented by a broad belt of gleaming spray; but no particle of this slipped into the mouth of the terrific funnel… “
In this passage, Poe describes one of the crucial feature of these rotating bodies of fluid: that they can be thought of as coherent islands in an incoherent flow. As such, they are essentially independent of their environment, surrounded by a seemingly impenetrable boundary and with little, if any, of the fluid inside them leaking out.
If you’re thinking that this description has a passing resemblance to a black hole, you’d be right. Haller and Beron-Vera put this similarity on a formal footing by describing the behaviour of vortices in turbulent fluids using the same mathematics that describe black holes.
In this picture, Poe’s “broad belt of gleaming spray” is exactly analogous to a photon sphere around a black hole. This is a surface of light which encircles a black hole without entering it.
Haller and Beron-Vera go on to show that each vortex boundary in a turbulent fluid contains a singularity, just like an astrophysical black hole.
That has important implications for the study of fluids and the identification of vortices, which are otherwise tricky to define and spot. In this case, it is simply question of looking for the singularity and the boundary that surrounds it.
And that’s exactly what Haller and Beron-Vera have done in the pattern of currents in the south west Indian Ocean and the South Atlantic. A well-known phenomenon in this part of the world is called the Agulhas leakage which comes from the Agulhas current in the Indian Ocean. “At the end of its southward flow, this boundary current turns back on itself, creating a loop that occasionally pinches off and releases eddies (Agulhas rings) into the South Atlantic,” they say.
These guys used satellite images of the South Atlantic Ocean from between November 2006 and February 2007 to look for vortices using a set of simple computational steps that spots black hole analogues.
In this three-month period they found eight candidates, two of which turned out to be black hole analogues containing photon spheres. “We have found exceptionally coherent material belts in the South Atlantic, filled with analogs of photon spheres around black holes,” they conclude.
That’s an interesting result that could have significant implications for our understanding of the way ocean currents transport material. Since anything that gets into these black holes cannot get out, this should trap any garbage, oil or indeed water itself, moving it coherently over vast distances. “Beyond the mathematical equivalence, there are also observational reasons for viewing coherent…eddies as black holes,” say Haller and Beron-Vera.
The work also raises the possibility that black hole analogues will occur in other situations, such as in hurricanes and not just on Earth. By this way of thinking, the Great Red Spot on Jupiter might well be the most famous black hole in the Solar System.

Satellites glimpse ultra-powerful “black hole” whirlpools in Atlantic
The whirpools - never witnessed before - would suck down ships, debris and even living creatures
By Chris Hall | Yahoo! News – Wed, Aug 21, 2013- Rex Features - Two mysterious 'black hole' whirlpools have been spotted in the South Atlantic ocean (Rex Features)
The whirpools - never witnessed before - would suck down ships, debris and even living creatures, moving 1.3 million cubic metres of water per second.
Two of the black holes - or “maelstroms” - have been sighted in three months by physicists from Zurich and Miami.
The powerful vortices of current have been described as ‘maelstroms’ and are ‘mathematical analogues’ for black holes – which is to say they do exactly the same with water that black holes do with light.
A whirlpool pictured by NASA.The discovery could give new insights into how oceanic currents transport debris and may even have implications for climate change studies.
Astronomical black holes bend space and time into a perpetually collapsing vortex. Light itself bends around them, which enables astronomers to recognise their existence.
Similarly, these oceanic maelstroms funnel current into an almost permanent spiral, trapping debris, oil and potentially living creatures in a body of water. Hardly anything leaks out.
The scientists used Edgar Allen Poe’s 1841 story ‘A descent into a Maelstrom’ to describe their discovery:
“The edge of the whirl was represented by a broad belt of gleaming spray; but no particle of this slipped into the mouth of the terrific funnel…”
The ability to apply the same mathematical principles to water currents on earth as black holes in space is an unexpected side-effect of the theory of general relativity.
This phenomenon has been observed in the South Atlantic and South-western Indian Ocean, using satellite imagery designed to spot the aquatic equivalent of black hole currents. According to scientists, the maelstroms are prevalent in this area thanks to the southbound Agulhas current in the Indian Ocean.
In a three-month period, two perfect matches were found to mimic black hole behaviour, “We have found exceptionally coherent material belts in the South Atlantic, filled with analogues of photon spheres around black holes,” said George Haller, from the Swiss Federal Institute of Technology in Zürich and Francisco Beron-Vera at the University of Miami in Florida, who worked on the study.
Top panel: Evolution of black-hole eddies (extracted from 3 months of data) in the South Atlantic over a period …The phrase ‘photon spheres’ refers to the light that is trapped around astronomical black holes, and in this instance is comparable to the rings of debris that are forming around these ocean maelstroms. As Haller and Beron-Vera’s findings note, ‘these vortices will capture and swallow nearby passively floating debris.’
In their research findings, Haller and Beron-Vora express their surprise at finding real-world examples that hold so closely to the theoretical equations. ‘Vortices in turbulence are often envisaged as rotating bodies of fluid, traveling as coherent islands in an otherwise incoherent ambient flow. This… …view is appealingly simple, yet challenging to apply in actual vortex detection.’
The maelstroms are detected by their rotating edges, which the scientists found were reliable indicators of the vortex within, based on pioneering research carried out by Stephen Hawking on black holes: ‘Intuitively, one expects that any…vortex in the fluid must contain such a singularity in its interior, just as all black holes are expected to contain Penrose-Hawking singularities. This expectation turns out to be correct’.
The singularities, as they have been termed, last for months at a time, moving across the ocean without interference from other currents.
Thus they can transport water of different temperatures and salinity to other areas of the ocean, potentially influencing the regional climate.
Haller and Beron-Vera found that the vortices transported water in a north-western direction 30% faster than had previously been reckoned – at a rate equating to 1.3 million cubic metres of water per second.
In addition, the maelstroms were found to occur four times deeper in the ocean than previously estimated; the study found examples as deep as 2000m below the surface.

Weather Disasters: Why Colorado?
Highway 72, Coal Creek Canyon
Adamus Saint-Germain: It is not “written” that there would be floods in Colorado in mid-September 2013, no more so than it is written or prophesied that there will be unprecedented cold in eastern Europe in the winter of 2013 – 14.
In the past, planetary weather tended to follow patterns and cycles that were influenced by but not limited to the stars and heavens, as well as the oceans, solar flares, etc. After the Lemurian times and into the mid-Atlantean era the weather was much more predictable than it is now. For instance, it would rain very 72 hours or so. But in current times the weather is not nearly so predictable because of the fast changes in human consciousness. One of the main factors for weather change outside of its normal cycle is human consciousness.
Let’s take the recent extreme rains and flooding in the Boulder, Colorado area to see how human consciousness and other factors create a huge storm. The area has a strong combination of mountain and mineral structure that “keeps energy moving.” Many high-consciousness humans have moved to this area in the past 30 years. It’s a university center, the headquarters for United States weather and geological studies, and home to many new high-tech businesses. This area is also one of the five U.S. Golden Cities*. It is alive with energies. Sometimes the energies can be overwhelming, but for those who are “on the go” this is an ideal area.
The normal weather patterns for this time of the year call for dry weather, and the beginning of the change of seasons. But the high energies and high human consciousness in this region acted like a weather magnet. In this case, it was about clearing old energies in order to keep the area from become energetically constipated. The “magnet” attracted exactly what was needed: Lots of cleansing moisture.
Note that southern Colorado, especially in the area of Colorado Springs with its military bases and training academies, and it’s many conservative Christian organizations, experienced two huge forest fires in the past year. Now the Boulder area, know for it’s liberal consciousness and more accepting views of spirituality, receives the opposite type of cleansing with the recent heavy rains. The rains cleared energetic debris from the forests and mountains, as well as the regional consciousness. The weather “magnetic” brought together several high moisture fronts and then caused the clouds to literally stop over the area for 3 – 4 days, washing the mountains, earth and human thoughts. It provides water energy for new growth.
For some Shaumbra this also relates to the “life-changing event” I mentioned at the Sedona workshop in June 2013.
There are many consequences of a storm like this. First, it draws international attention to the area, which helps connect the consciousness of the Boulder, Colorado region to the world, along with the “higher potentials” this area can offer other parts of the world. The floods will also bring hundreds of millions of dollars into the region for infrastructure repair. Once the repairs are completed this area will have some of the best roads anywhere in the US. Even though this was called a “Disaster of Biblical Proportions” there was very little loss of human life. Hundreds of thousands of people impacted by the storm had the opportunity to take a look at what’s important in their lives and to make the quick adjustments in their consciousness. The area will rebuild quickly and life will get back to normal, but with a new sparkle and dynamic. You ask if this would be a good time to move to the area, and the answer is yes, if it feels right for you. But make sure you’re ready to handle strong, clear energies.
Please note that there will be a small after-effect of this storm. It will be a secondary clearing, shaking loose the old residual energies that might have held on during the storm. It will most likely come as very strong winds in the late autumn timeframe, followed by colder-than-usual temperatures and then a big snowfall to blanket the area with crystal white energies during the healing process.
It’s important to note that you can live in the midst of a storm and not fear for your life, as so many Shaumbra did recently. You can embrace the clearing on a very personal level, breathing into the storm and allowing it to also clear some stagnant energies within you. After all, Shaumbra pirates always seem to enjoy a good adventure. They tend to get very bored when things aren’t moving fast.

* Saint-Germain provided information about the Golden Cities to Tori Toye in 1983. Since then it has been published in the “I AM… America” maps and books. (http://iamamericabookstore.iaabooks.com) It’s no wonder that the Crimson Circle is headquartered in Golden, Colorado, in the heart of one of the five golden centers.
Editor’s Note: Due to extreme road damage and resulting closure of highway 72 leading into Coal Creek Canyon, we recommend that you watch or listen to the October Shoud online rather than trying to attend in person. For the few hardy souls who want to attend anyway, please check for up-to-date road information before attempting the trip. The only route that will be passable for a while takes about 90 minutes from Golden or Boulder, rather than the usual 30 minutes.
We are also grateful that the homes of all Crimson Circle staff who live in Coal Creek Canyon and the surrounding areas have sustained little or no damage. Some are without natural gas but we consider this a minor inconvenience, all things considered. And we truly appreciate all the messages of love and goodwill that have been received from Shaumbra around the world!
P.S. Watch for the upcoming Shaumbra Magainze next week for a special excerpt of a Keahak channel from Adamus, talking about some of these energies!»
