The researchers say that the symmetric and isotropic universe should have formed from a spherically symmetric explosion .
研究者说对称的，各向同性的宇宙应该是形成于一个球对称的大爆炸中。
That is , the matter in the universe is homogeneous and isotropic when averaged over very large scales .
也就是说，把宇宙中的物质在非常大的空间尺度上平均的来考虑的话，他们是均匀和各向同性的。
He commented that the results of the research are important because they seem to contradict the nearly universal notion that at a sufficiently large scale , the universe is isotropic , i.e. , does not have a pronounced direction .
