【正文】 Computer極精妙的時(shí)間消逝場(chǎng)景 The team then created both“snapshots快照 ”of fully formed universe and views of what an observer would actually see in looking deeper and deeper into the universe from one point. The farther the observer looks, the longer it has taken for light to arrive from that point, so the view gradually moves to earlier times in cosmic history along a wedgelike bundle of lines of sight. Even veteran researchers in the consortium were taken aback by the stunning detail seen in these timelapse pictures, which were created mostly by Evrard.(協(xié)會(huì)最有經(jīng)驗(yàn)的研究者通過(guò)主要由 Evrard創(chuàng)建的極精妙的時(shí)間消逝場(chǎng)景而帶入過(guò)去 ). Says Carlos Frenk of the University of Durham in the ., who codirects the consortium with White, “I was amazed that even at very early times, you see a huge amount of structure”—filaments and walls like the ones that observers have seen in the nearby universe. Agrees Evrard: “You start to pick out subtleties that you wouldn39。t have imagined. It blows you mind.” Environmental Geology星際環(huán)境 The Universe Environment4） 宇 宙形成的計(jì)算機(jī)模擬 Cosmos in a Computer 模型的缺陷 So far, the lambda model seems to be a little closer to the real universe. Large clusters of galaxies form earlier in the lambda model than in the omega = 1 version, more in line with observations. Both models have difficulty accounting for some of the most massive and distant clusters seen in the real sky, however.

And because the team plans to make its data public, other researchers will be able to make their own journeys through the far reaches of this silicon universe.
