breezy posted a topic in General DiscussionScientists discover three new planets similar to Earth May 3, 2016 "SCIENTISTS have discovered a trio of Earth-like planets that are the best bet so far for finding life outside our solar system. The three orbit an ultracool dwarf star a mere 39 light years away, and are likely comparable in size and temperature to Earth and Venus, they reported in a study, published in Nature. “This is the first opportunity to find chemical traces of life outside our solar system,” said lead author Michael Gillon, an astrophysicist at the University of Liege in Belgium. All three planets had the “winning combination” of being similar in size to Earth, “potentially habitable” and close enough so their atmospheres can be analysed with current technology, he told AFP. The find opens up a whole new “hunting ground” for habitable planets, he added. Gallon and colleagues calibrated a 60-centimetre telescope in Chile, known as TRAPPIST, to track several dozen dwarf stars neither big nor hot enough to be visible with optical telescopes. They zeroed in on a particularly promising one, now known as TRAPPIST-1, about one eighth the size of the Sun, and significantly cooler. Observing it for months, the astronomers noticed that its infra-red signal faded slightly at regular intervals, evidence of objects in orbit. Further analysis confirmed they were exoplanets — planets revolving around stars outside our solar system." snip http://www.news.com.au/technology/science/space/scientists-discover-three-new-planets-similar-to-earth/news-story/7e214c575481ed77706c5b3ea796f22c

Scientists say that signals from the furthest reaches of space suggest that the fabric of our universe is being disrupted by another universe. The discovery could provide proof of the multiverse theory, which says that there are many alternate universes. We may have just, for the first time ever, caught a momentous glimpse of a parallel universe bumping against our own. Scientists say that signals from the furthest reaches of space suggest that the fabric of our universe is being disrupted by another universe. The discovery could provide proof of the multiverse theory, which says that there are many alternate universes. Dr. Ranga-Ram Chary examined the noise and residual signals in the cosmic microwave background left over from the Big Bang and found a number of scattered bright spots which he believes may be signals of another universe bumping into our own billions of years ago Dr. Ranga-Ram Chary, a researcher at the California Institute of Technology in Pasadena, examined data from the cosmic microwave background gathered by the European Space Agency’s Planck Space Telescope. Within this glow left over from the moments after the Big Bang, he discovered a number of spots where the microwave light was far brighter than it should be. He claims that theses may be signals caused by the interaction between our universe and another one a few hundred thousand years after the Big Bang around 13.8 billion years ago." The existence of multiple universes – a multiverse – has been considered scientifically plausible. If all these universes emerged from the same Big Bang, then they’re likely sitting together in a row, vibrating. According to the theory, if these universes touch one another, the resulting collision would leave some sort of evidence. According to New Scientist, which first reported the Dr. Chary’s research, this is akin to two bubbles bumping into each other. These so-called “bubble universes”, which are expanding within the multiverse, bumped into each other as they expanded after the Big Bang, leaving an imprint on each other’s outer surface." snip http://upriser.com/posts/scientists-may-have-just-discovered-a-parallel-universe-leaking-into-ours Credit for this story goes to phillipbbg's shout very interesting read
WellNow posted a topic in General DiscussionThis article has some amazing tidbits about Seattle history and lithography, however my highlights point to something perhaps more amazing. Check it: http://www.nytimes.com/2013/12/20/us/under-seattle-a-big-object-blocks-bertha-what-is-it.html?_r=0 Something unknown, engineers say — and all the more intriguing to many residents for being unknown — has blocked the progress of the biggest-diameter tunnel-boring machine in use on the planet, a high-tech, largely automated wonder called Bertha. At five stories high with a crew of 20, the cigar-shaped behemoth was grinding away underground on a two-mile-long, $3.1 billion highway tunnel under the city’s waterfront on Dec. 6 when it encountered something in its path that managers still simply refer to as “the object.” The object’s composition and provenance remain unknown almost two weeks after first contact because in a state-of-the-art tunneling machine, as it turns out, you can’t exactly poke your head out the window and look. “What we’re focusing on now is creating conditions that will allow us to enter the chamber behind the cutter head and see what the situation is,” Chris Dixon, the project manager at Seattle Tunnel Partners, the construction contractor, said in an interview this week. Mr. Dixon said he felt pretty confident that the blockage will turn out to be nothing more or less romantic than a giant boulder, perhaps left over from the Ice Age glaciers that scoured and crushed this corner of the continent 17,000 years ago. But the unknown is a tantalizing subject. Some residents said they believe, or want to believe, that a piece of old Seattle, buried in the pell-mell rush of city-building in the 1800s, when a mucky waterfront wetland was filled in to make room for commerce, could be Bertha’s big trouble. That theory is bolstered by the fact that the blocked tunnel section is also in the shallowest portion of the route, with the top of the machine only around 45 feet below street grade. “I’m going to believe it’s a piece of Seattle history until proven otherwise,” said Ann Ferguson, the curator of the Seattle Collection at the Seattle Public Library, who said she held out hope for something of 1890s Klondike Gold Rush vintage, when Seattle became the crazed and booming gateway city to the gold fields of Alaska and Canada. ... efforts to drain water and reduce pressure at the drill head, with a series of bore holes pushed down in recent days, could allow workers to get safe access to the blocked site as early as Friday. But working at atmospheric pressures similar to what a diver would experience, the team could stay down only for short periods, and each visitor would then need time in a decompression chamber. ... If the object can’t be broken up below ground, there would need to be excavation down from the street. The tunnel is to run north and south along Elliott Bay from Century Link Field, home of football’s Seahawks, to a point near the Space Needle on the north, allowing demolition of an elevated roadway and improved crosstown foot and bicycle access. ... nlike Boston or New York, where tunnels are common and bedrock is close to the surface, getting to that end point is messy. Seattle’s underbelly is more like pudding than soil — a slurry of sand, gravel and clay, all jumbled and compressed by the pressures from a 3,000-foot-thick ice sheet that extended as far as Olympia, 50 miles south. A city famous for being wet also has a high water table, only about four to five feet down. And because Seattle, as first encountered by European-American settlers, was hardly conducive to being a city at all, with steep, glacier-carved hills rolling right down to the water, the landscape was reshaped from the beginning, with projects to grind down the hills. That in turn created lots of landfill, which went into the waterfront to level it and create land on which the city’s commercial center rose. “It’s mind-boggling how much we have altered the landscape of Seattle,” said David B. Williams, a geologist and author of a coming book about the making of Seattle’s landscape, called “Too High and Too Steep, Reshaping Seattle’s Topography.” “The tunnel is just a continuation of that story,” he said as he walked north of downtown, where a cliff face showed the layered strata of the geologic past. ... In the end, [Williams] said, state engineers are probably right. A rock, huge in size or in a configuration that the machine cannot quite get purchase on to grind, is the most likely culprit. “I do hope it is not,” he said. “It would be great to find some new mystery.”
breezy posted a topic in ANCIENT MYSTERIESGiant channels discovered beneath Antarctic ice shelf 10/6/13 The British Antarctic Survey's Twin Otter survey plane & camp, the plane was used to collect data about the size of the sub-ice-shelf channel. Credit: Neil Ross "Scientists have discovered huge ice channels beneath a floating ice shelf in Antarctica. At 250 metres high, the channels are almost as tall as the Eiffel tower and stretch hundreds of kilometres along the ice shelf. The channels are likely to influence the stability of the ice shelf and their discovery will help researchers understand how the ice will respond to changing environmental conditions." Researchers from the University of Exeter, Newcastle University, the University of Bristol, the University of Edinburgh, the British Antarctic Survey and the University of York, used satellite images and airborne radar measurements to reveal the channels under the ice shelf. The channels can be seen on the surface of the ice shelf, as well as underneath, because the ice floats at a different height depending on its thickness." http://phys.org/news/2013-10-giant-channels-beneath-antarctic-ice.html Gigantic Channels Beneath Antarctica's Ice Shelf Discovered http://www.youtube.com/watch?v=_L96M0m7rSM The Cosmos News October 7, 2013
