They were, by far, the largest and most distant objects that scientists had ever decteded: a strip of enourmous cosmic clouds some 15 billion light years from earth. 71) But even more important, it was the farthest that scientists had been able to look into the past, for what they were seeing were the patterns and structures that existed 15 billion years ago. That was just about the moment that the universe was born. What the researchers found was at once both amazing and expected; the US National Aeronautics and Space Administratins Cosmic Background Explorer satellite -Cobe-had disvocered landmark evidence that the universe did in fact begin with the primeval explosion that has become known as the Big Bang(the theory that the universe originated in an explosion from a single mass of energy). 72) The existence of the giant clouds was virtually required for the Big Bang, first put forward in the 1920s, to maintain its reign as the dominant explanation of the cosmos. According the the theory, the universe burst into being as a submicroscopic, unimaginable dense knot of pure energy that flew outward in all directions, emitting radiation as it went, condensing into particles and then into atoms of gas. Over billions of years, the gas was compressed by gravity into galaxies, stars, plants and eventully, even humans. 环球雅思-中国第一雅思品牌 名师阵容 国内最大的连锁外语培训机构，被评为全国十大知名学校，连续多年荣膺中国最具影响力培训集团称号... 北京新航道学校-胡敏“中国雅思之父” 多所世界名校，可根据意愿选择留学国家与学校、国内两年、国外两年，节省大量费用与一年学习时间 北京雅思学校-刘洪波、张皓亲自授课 北雅 IELTS 培训基地是全国最早、最权威进行 IELTS 考试培训研究的专业化、正规化机构，强大的师资。 上海朗阁雅思学校-南方雅思培训首选 国内最大的雅思培训基地。拥有上百位全职中外雅思专家，25人小班授课、中外专家联合执教、保分承诺   韩企、日企定向培养 北京理工大学校本部招生   中国人民大学计划外 北京文理研修学院招生 Cobe is designed to see just the biggest structures, but astronomers would like to see much smaller hot spots as well, the seeds of local objects like clusters and superclusters of galaxies. They shouldnt have long to wait. 73) Astrophysicists working with ground based detectors at the South Pole and balloon borne instruments are closing in on such structures, and may report their findings soon. 74) If the small hot spots look as expected, that will be a triumph for yet another scientific idea, a refinement of the Big Bang called the inflationary universe theory. Inflation says that very early on, the unverse expanded in size by more than a trillion trillion trillion trillionfold in much less than a second, propelled by a sort of antigravity. 75) Odd though it sounds, cosmic inflation is a scientifically plausible consequence of some respected ideas in elementary particle physics, and many astrophysicists have been conviced for the better part of a decade that it is true.
