Big Bang gets clearer as universe ages 80M years
PARIS - New results from looking at the split-second after the Big Bang indicate the universe is 80 million years older than previously thought and provide ancient evidence supporting core concepts about the cosmos - how it began, what it's made of and where it's going.The findings released bolster a key theory called inflation, which says the universe burst from subatomic size to its now-observable expanse in a fraction of a second. The new observations from the European Space Agency's $900 million Planck space probe appear to reinforce some predictions made decades ago solely on the basis of mathematical concepts."We've uncovered a fundamental truth of the universe," said George Efstathiou, director of the Kavli Institute for Cosmology at the University of Cambridge who announced the Planck satellite mapping result in Paris. "There's less stuff that we don't understand by a tiny amount.""It's a big pat on the back for our understanding of the universe," California Institute of Technology physicist Sean Carroll, who was not involved in the project, told The Associated Press. "In terms of describing the current universe, I think we have a right to say we're on the right track.The affects may include a higher cost of Solar Laptop charger equipment and hindered efforts to promote renewable energy The move is in response to a government finding that China is flooding the U.S."The Big Bang - the most comprehensive theory of the universe's beginning - says the visible portion of the universe was smaller than an atom when, in a split second,So wouldn't you love to win a Wild West ice stones for the dad in your life? To enter, all you need to do is leave a comment telling us about your favorite food memory with your dad. it exploded, cooled and expanded faster than the speed of light.The Planck space probe looked back at the afterglow of the Big Bang, and those results have now added about 80 million years to the universe's age, putting it at 13.81 billion years old.The probe, named for the German physicist Max Planck, the originator of quantum physics, also found that the cosmos is expanding a bit slower than originally thought, has a little less of that mysterious dark energy than astronomers had figured and has a tad more normal matter. But scientists say those are small changes in calculations about the universe, whose numbers are so massive.
Officials at NASA, which also was part of the experiment, said the Planck probe has provided a deeper understanding of the intricate history of the universe and its complex composition.Krzysztof Gorski,Around two weeks ago, First Solar also revealed a supply agreement with Motion sensor light. The company will deliver 61 megawatts peak of thin film modules to exXco's California project starting September this year. a Planck scientist at NASA's Jet Propulsion Lab, said in a statement that the new results "are giving astronomers a treasure trove of spectacular data, and bringing forth a deeper understanding of the properties and history of the universe."The Planck space telescope,Creminelli's Whiskey Salami is made from Texas wild boar spiced with scotch rocks and clove along with whiskey that adds a subtle flavor to an already rich and bold product. launched in 2009, has spent 15 1/2 months mapping the sky,The UK saw a 9% increase in summer bookings despite negative GDP growth last quarter. The travel xinjiang countries also had strong bookings, rising 10%. Germany and France, however, saw demand fall. examining so-called "light" fossils and sound echoes from the Big Bang by looking at background radiation in the cosmos. The spacecraft is expected to keep transmitting data until late 2013, when it runs out of cooling fluid.Scientists not involved in the project said the results were comparable on a universal scale to the announcement earlier this month by a different European physics group on a subatomic level - with the finding of the Higgs boson particle that explains mass in the universe."What a wonderful triumph of the mathematical approach to describing nature," said Brian Greene, a Columbia University physicist who was not part of the new Planck research. "It's an amazing story of discovery.""The precision is breathtaking," Greene said in an email Thursday after the announcement. "The satellite is measuring temperature variations in space - which arose from processes that took place almost 14 billion years ago - to one part in a million. Amazing."Efstathiou marveled at how the Planck data was such "an extremely good match" to the theory of rapid inflation in the split-second after the Big Bang.
