So maybe physics can fill this blank, and indeed, since about the late 1960s or around 1970, physicists have purported to give a purely scientific explanation of how a universe like ours could have popped into existence out of sheer nothingness, a quantum fluctuation out of the void.
所以，物理学或许能填入上述等式的空白， 事实上，自从上世纪六十年代末七十年代初， 物理学家们声称， 已能够用纯科学的理论 来解释像我们这样的宇宙的起源， 如何从无到有地产生， 即量子波动，源于空。
