I do know I've thought about this, and even had one of those "moments of realization" on the drive home from my first lecture on DCTs, where I thought I could transform all of human history from time domain to frequency domain and how this would bring out certain patterns and truths that could not be understood otherwise. I swear I wasn't on drugs! (Though the lecture was in fact given by Prof. Marshall of Rutgers, the father of the lyricist for the rock band Phish, at whose concerts I have imbibed certain substances... but I digress.) The frequency domain is just as "real" as any other mathematical construction that can help us understand everything.
