<br />
==特性==<br />
U1.11距[[克劳斯-坎普萨诺超大类星体群]]约2°<ref name=ClowesSep2011 />，[[红移]]量为1.11（換算後约88亿[[光年]]远），因而得名U1.11<ref name=ClowesSep2011 />。它毗邻[[克劳斯-坎普萨诺超大类星体群]]，相对靠近另外一个[[超大类星体群]]U1.54<ref name=ClowesSep2011 />，包含了38个类星体，<ref name=ClowesSep2011 />可能触发過[[大尺度纤维状结构]]的演化。<br />
<br />
==宇宙论原则==<br />
根据[[宇宙论原则]]，宇宙中不同部分内部的[[物质]]和[[能量]]的随机分布必须近似地均匀且各向同性，这些物体如果展现在一个足够大的尺度上时，它们随机过密必须要小。同时亚达夫展示了结构性尺寸的最大值约为260百万秒差距<ref name="Yadav">{{cite journal|last=Yadav|first=Jaswant|author2=J. S.
