Research over the past 25 years has led to the view that the rich tapestry of present-day cosmic structure arose during the first instants of creation, where weak ripples were imposed on the otherwise uniform and rapidly expanding primordial soup. Over 14 billion years of evolution, these ripples have been amplified to enormous proportions by gravitational forces, producing ever-growing concentrations of dark matter in which ordinary gases cool, condense and fragment to make galaxies. This process can be faithfully mimicked in large computer simulations, and tested by observations that probe the history of the Universe starting from just 400,000 years after the Big Bang.
过去25年的研究得出了这样一种观点：当今宇宙结构丰富多彩的图景是在创世的最初瞬间形成的，当时在原本均匀且迅速膨胀的原初物质汤中产生了微弱的涟漪。经过140多亿年的演化，这些涟漪被引力放大到巨大规模，产生了越来越多的暗物质聚集区，普通气体在其中冷却、凝聚并碎裂形成星系。这个过程可以在大型计算机模拟中得到如实模拟，并通过从大爆炸后仅40万年开始探测宇宙历史的观测进行检验。
