论文摘要
如果微波背景异常是由于宇宙拓扑引起的，那么宇宙周围宇宙周围的最短距离就不太可能大得多。我们表明，在微波背景中缺乏匹配的温度圆而产生的观察性约束留下了此类拓扑的许多可能性。我们评估了微波背景多极相关性在样本案例中的可检测性。搜索可能拓扑的大空间中观察数据中的拓扑签名构成了巨大的计算挑战。
The shortest distance around the Universe through us is unlikely to be much larger than the horizon diameter if microwave background anomalies are due to cosmic topology. We show that observational constraints from the lack of matched temperature circles in the microwave background leave many possibilities for such topologies. We evaluate the detectability of microwave background multipole correlations for sample cases. Searches for topology signatures in observational data over the large space of possible topologies pose a formidable computational challenge.
