According to the theory,the universe burst into being as a submicroscopic, unimaginably dense knot of pure energy that flew outwards in all directions,emitting radiation as it went ,condensing into particles and then into atoms of gas.请帮忙分析下这一句的结构。另请翻译该句子。谢谢as在这里是做“作为”这个意思讲吗?然后后面的两个emitting ,condensing 是现在分词作伴随状语?
