一个观测团队使用南极望远镜(SPT),已经对宇宙微波背景辐射(CMB)中的B-模式光偏振做出了首次探测(见图1)。在CMB中,这种具有微妙卷曲特性的偏振光组分早已被预言存在。作为宇宙大爆炸模型的关键预言之一,它的被证实将为暴胀理论的最终测试铺平道路。Chuck Bennett是美国马里兰州霍普金斯大学CMB观测站的首席科学 A team of observers used the South Pole Telescope (SPT) to make the first detection of B-mode light polarization in the CMB (Figure 1). In CMB, this polarized light component with subtle crimp properties has long been predicted to exist. As one of the key predictions of the Big Bang model, it’s proven to pave the way for the ultimate test of inflation theory.
