  7. Since this discovery, the expansion and cooling of the universe has been the unifying theme of cosmology, much as darwinian evolution is the unifying theme of biology

    自此之後，宇宙的膨脹與冷卻便成了宇宙學中的主要論點，就如同達爾文的演化論是生物學的主流思想一樣。
  8. The expansion of the universe is like darwinian evolution in another curious way : most scientists think they understand it, but few agree on what it really means

    宇宙的膨脹和達爾文的演化論，還有著另一個古怪的相似處：大部份科學家都認為他們了解這個理論，可是對其真正的涵義，卻很少意見一致。
  9. Since substances attract each other under gravitational pull, it will slow down the expansion of the universe

    由於物質間的萬有引力是相吸的，它會阻遏宇宙的膨脹。
  10. Is not only a parameter for measuring expansion of the universe, it can also be used to determine the age and the size of the universe, amount of dark matters, numbers of hadrons and abundance of light elements in the universe and even the structure of the early universe, and so forth

    的一個參數，而且還可以用來計算宇宙年宇宙大小宇宙中黑暗物質的數量重子數目輕元素豐度甚至早期宇宙形成的結構等等。
  11. Because of the universe ' s expansion, the light from distant sources has been stretched, shifting its wavelength toward the red end of the spectrum

    因為宇宙膨脹的緣故，來自遠處的光會被拉長，因此波長將會往光譜的紅端偏移。
  12. Forty years ago this july, scientists announced the discovery of definitive evidence for the expansion of the universe from a hotter, denser, primordial state

    在40年前的那個7月，科學家宣布他們找到了確切的證據，可以證明宇宙是從一個高熱、高密度的太初狀態，逐漸膨脹而成。
  13. The find indicates, for example, that dark energy isn ' t being diluted by the expansion of the universe

    比方說，這次的發現表明，暗能量並沒有隨著宇宙的膨脹而變弱。
  14. However, physicists inclined to believe that the total mass of the universe will be " just right ", that means it is enough to stop the expansion of the universe at last but is not enough to pull it back. hence, the universe is neither closed nor open but a flat universe

    不過，很多物理學家傾向相信宇宙中的物質質量不太多也不太少，膨脹會逐漸緩慢下來，但永遠不會收縮，宇宙既非封閉也非開放，而是介乎兩者之間的平面宇宙。
  15. The build - up of dark haloes in cdm models generally consists of an early phase of fast accretion [ where the halo mass mh increases with time much faster than the expansion rate of the universe ] and a late phase of slow accretion [ where mh increases with time approximately the same as the expansion rate ]

    我們同時發現： （ 1 ）冷暗物質模型（ cdm ）中暗暈的成長均包括一個早期的快速吸積階段[暗暈質量m _ h隨時間的增長遠快于宇宙的膨脹速率和一個晚期的緩慢吸積階段

  17. The basic framework is the standard big bang theory for the expansion of the universe

    基本的架構是解釋宇宙膨脹的標準大霹靂理論。
  18. Edwin hubble was the first astronomer to describe the expansion of the universe, in a physical formulation made in 1929 that now bears his name

    愛德溫?哈勃是描述宇宙之膨脹第一人，在1929年他得出了此方面的物理公式，現在則以他的名字命名。
  19. Through the expansion of the universe, the gas cooled and condensed into the myriad galaxies found today

    經宇宙膨脹后，氣體冷卻並凝縮成無數今日可見的星系。
  20. There are two major errors. the first one is the error occurred in measuring v. although astronomers can locate v of individual galaxy accurately through the spectrum and the doppler s effect, owing to the gravitational pull exerted from neighbouring galaxies and clusters of galaxies, v is not wholly determined by the expansion of the universe

    有兩個主要的誤差：第一個是測量退行速度的誤差，雖然天文學家利用光譜及多普勒效應，已經很準確地找到個別星系的退行速度，但由於與鄰近星系及星系團的引力作用，這個退行速度便不完全是因宇宙膨
