Inflationary Universe - Early Growth Spurt Inbox x Rana Bose 8:37 PM (1 hour ago) to me Evidence spotted for universe's early growth spurt NEW YORK (AP) — The universe was born almost 14 billion years ago, exploding into existence in an event called the Big Bang. Now researchers say they've spotted evidence that a split-second later, the expansion of the cosmos began with a powerful jump-start. Experts called the discovery a major advance if confirmed by others. Although many scientists already believed that initial, extremely rapid growth spurt happened, finding this evidence has been a key goal in the study of the universe. Researchers reported Monday that they did it by peering into the faint light that remains from the Big Bang. If verified, the discovery "gives us a window on the universe at the very beginning," when it was far less than one-trillionth of a second old, said theoretical physicist Lawrence Krauss of Arizona State University, who was not involved in the work. "It's just amazing," he said. "You can see back to the beginning of time." Another outside expert, physicist Alan Guth of the Massachusetts Institute of Technology, said the finding already suggests that some ideas about the rapid expansion of the universe can be ruled out. Right after the Big Bang, the universe was a hot soup of particles. It took about 380,000 years to cool enough that the particles could form atoms, then stars and galaxies. Billions of years later, planets formed from gas and dust that were orbiting stars. The universe has continued to spread out. Krauss said he thinks the new finding could rank with the greatest discoveries about the universe over the last 25 years, such as the Nobel prize-winning discovery that the universe's expansion is accelerating. The new results were announced by a collaboration that includes researchers from the Harvard-Smithsonian Center for Astrophysics, the University of Minnesota, Stanford University, the California Institute of Technology and NASA's Jet Propulsion Laboratory. The team plans to submit its results to a scientific journal this week, said its leader, John Kovac of Harvard. For their research, astronomers scanned about 2 percent of the sky for three years with a telescope at the South Pole, chosen for its very dry air to aid in the observations. They were looking for a specific pattern in light waves within the faint microwave glow left over from the Big Bang. The pattern has long been considered evidence of the rapid growth spurt, known as inflation. Kovac called it "the smoking gun signature of inflation." The scientists say the light-wave pattern was caused by gravitational waves, which are ripples in the interweaving of space and time that sprawls through the universe. If confirmed, the new work would be the first detection of such waves from the birth of the universe, which have been called the first tremors of the Big Bang. Arizona State's Krauss cautioned that it's possible that the light-wave pattern is not a sign of inflation, although he stressed that it's "extremely likely" that it is. It's "our best hope" for a direct test of whether the rapid growth spurt happened, he said. Krauss and other experts said the results must be verified by other observations, a standard caveat in science. Marc Kamionkowski, a theoretical physicist at Johns Hopkins University who didn't participate in the work, called the detection of the light-wave pattern "huge news" for the study of the cosmos. "It's not every day you wake up and learn something completely new about the early universe," he said.

Then  the  Universe  became   round  with  our  lone  galaxy .  Then   Came  multiple  Galaxy  &  Cosmology  of   Einstein.  Then  there   not  one   Universe  and  Single  BIG BANG   but  Multipe ' BANGS '  and  breeding  Universes  with  Parallel  universes ( Michio Kaku). So  where  is  the  end  .  Best  thing  is  tat we   are  speculate  any  thing  in  any  way !   And even  Scientific   Superstition  is  even  Out - Reaching  Religious  superstitions !! for   example  :  If there  was  a  Big  Bang    who heard  it   first  or  ever    OR   If  there  was  God  - Particle   who  saw  that   original  "  God-damn   Particle ' . Maybe ,   we  need   Sukumar  Ray  again for  some  enjoyable  "Abol - Tabol"   compositions  !!!
