Sometimes the title itself generates a kind of excitement in your brain and you start answering it before you even read the blog post. And in this case as others have noticed, it's not exactly answered in the way some of us would.
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.
