Here is an interesting interview from many years ago;

The question then is, what are "waves?"

are they tiny vibrating strings?

While we might have different terms, my view is that energy drives the wave, the fluctuations rise and fall, so the energy is going past to future, as the patterns come and go, future to past.

The problem is how far down that conceptual rabbit hole can you go, before running out of terms and concepts to light the way and do you assume the last conceptual entity is the end of the line, or it just the end of our ability to generate concepts to frame it.
