As a subject matter expert in philosophy and Latin phrases, I can explain the meaning of "ex nihilo nihil fit," which is a Latin phrase with philosophical implications.

English Answer:
"Ex nihilo nihil fit" translates to "out of nothing, nothing comes" or "nothing comes from nothing." This is a fundamental principle in philosophy that asserts that nothing can be created from absolute nothingness. It is closely related to the principle of sufficient reason, which states that everything has a reason or cause. In a cosmological context, this phrase is often used to discuss the origins of the universe, suggesting that something cannot arise spontaneously from complete non-existence without a cause or creator.

中文回答：
"Ex nihilo nihil fit" 的意思是“无中不能生有”或“从虚无中什么也不会产生”。这是哲学中的一个基本原则，它断言从绝对的虚无中不能创造出任何事物。这个原则与充足理由原则密切相关，充足理由原则指出一切事物都有其原因或起因。在宇宙学的背景下，这个短语经常用来讨论宇宙的起源，暗示某物不能在没有原因或创造者的情况下从完全的不存在中自发产生。
