Jo-Anne Brown博士， Calgary大學(xué)物理學(xué)副教授，他的解釋是銀河系的磁場(chǎng)將燬滅地球。
Perhaps, some have suggested, a huge black hole simply collapses out of a pre-galactic cloud and serves as a ready-made engine to drive further galaxy development.
一些人已經(jīng)提出，也許一個(gè)巨大的黑洞衹是一個(gè)前星系雲(yún)崩塌的結(jié)果，它衹是作爲(wèi)一個(gè)對(duì)於推動(dòng)未來的星系發(fā)展的縣城的引擎存在。

Just as in a container, molecules in an inter-galactic gas cloud absorb certain wavelengths and leave a pattern of dark lines on a quasar's spectrum.
