Although cold dark matter has its own problems in explaining cosmic structures [ see “ the life cycle of galaxies ” by guinevere kauffmann and frank van den bosch ; scientific american , june 2002 ] , most cosmologists consider these problems minor compared with the difficulties faced by alternative hypotheses 雖然冷暗物質在解釋宇宙結構上也有它自身的問題(見《科學人》 2002年8月號星系傳奇) ,但大多數宇宙學家認為,較諸其他假說所面對的困難,這些問題可說是次要的。

The current standard model of elementary particles contains no examples of particles that could serve as cold dark matter , but extensions of the standard model ? developed for reasons quite separate from the needs of astronomy ? offer many plausible candidates 現今的基本粒子標準模型內,并沒有任何粒子可以構成冷暗物質,但從標準模型加以推廣,則提供了許多可能的候選者,而推廣的理由則和天文學上的需求并沒有多少關聯。

In addition , experiments are under way to detect mysterious particles that form the cold dark matter of the universe and to examine protons at higher levels of sensitivity to learn whether they decay 此外,已經有實驗開始偵測構成宇宙冷暗物質的神秘粒子,精密度較高的實驗也在檢查質子是否會發生衰變。
