The Milne model was a special-relativistic cosmological model proposed by Edward Arthur Milne in 1935. It is mathematically equivalent to a special case of the FLRW model in the limit of zero energy density and it obeys the cosmological principle. The Milne model is also similar to Rindler space, a simple re-parameterization of flat Minkowski space.

rdfs:comment	نموذج ميلن هو نموذج علمي في علم الكون الفيزيائي وفقًا لنظرية النسبية الخاصة اقترحه إدوارد آرثر ميلن سنة 1935 م، وهو يُعد حالة رياضياتية خاصة لإحداثيات روبرتسون-ووكر افتُرض فيه أن كثافة الطاقة صفرية (بمعنى آخر، أن الكون فارغ)، وتخضع للمبدأ الكوني. يُشبه نموذج ميلن أيضًا فضاء ريندلر، الذي هو إعادة تمثيل وسيطي مُسطّح بسيط لفضاء مينكوفسكي. (ar) Il modello di Milne era un modello cosmologico basato sulla relatività speciale proposto da Edward Arthur Milne. È un caso particolare della metrica FLRW nel limite in cui la densità tende a zero ed esso segue il principio cosmologico; tuttavia la previsione data da questo modello, ovvero una densità critica Ωtot prossima a zero e una curvatura spaziale negativa, è in contraddizione con le osservazioni che mostrano una densità critica prossima a uno e una curvatura spaziale nulla. (it) 米尔恩模型是英国天文学家米尔恩（英語：Milne）于1935年提出的狭义相对论性的宇宙模型。该模型服从宇宙学原理，在数学上等效于弗里德曼-罗伯逊-沃尔克模型在零能量密度极限下的近似，因此也叫空宇宙模型。米尔恩模型和（对平直闵可夫斯基时空的简单再）相似。由于米尔恩模型的零能量密度性和最大负空间曲率性，它和目前的宇宙学观测相矛盾。目前的观测表明宇宙的密度参数为一，曲率为零（平直）。 (zh) The Milne model was a special-relativistic cosmological model proposed by Edward Arthur Milne in 1935.

(en) L'univers de Milne ou modèle de Milne est un ancien modèle cosmologique proposé par Edward Arthur Milne. Il est classiquement interprété comme étant la limite d'un univers en expansion quand la densité de matière devient négligeable devant la densité critique. Du fait que l'univers de Milne est essentiellement vide de matière, il peut être décrit dans le seul cadre de la relativité restreinte, sans avoir à utiliser la machinerie plus complexe de la relativité générale, d'ordinaire indispensable pour la description de tout modèle cosmologique. (fr) Modelo de Milne foi um modelo cosmológico relativista especial proposto por Edward Arthur Milne em 1935. É matematicamente equivalente a um caso especial do modelo FLRW no limite de densidade de energia zero (ou seja, um universo vazio) e obedece princípio cosmológico. O modelo de Milne também é semelhante ao , uma simples re-parametrização do espaço de Minkowski. (pt)
