Almost anything can be discovered if you’re willing to go for seven levels.

If the first source you ask doesn’t know an answer, ask them who you should ask next, and so on down the line. For some scholarly stuff, the person you “ask” might be someone long dead, but nevertheless someone who gives answers.

If you’re willing to go all the way down to seven levels, almost anything can be found out, from the mundane to the profound.

Keep searching. Don’t be afraid to dig. Find the answers you need.
