As a language expert with a deep understanding of idiomatic expressions, I can explain the phrase "to go down the rabbit hole" in English and then provide a translation in Chinese.

In English, the phrase "to go down the rabbit hole" is often used to describe the experience of becoming deeply engrossed or immersed in something, typically something that is complex, mysterious, or difficult to navigate. The expression is derived from Lewis Carroll's "Alice's Adventures in Wonderland," where Alice goes down a rabbit hole and discovers a surreal world. In modern usage, it can refer to a wide range of activities, from researching a topic extensively to becoming absorbed in a book, movie, or even a philosophical or intellectual pursuit.
