Sonoluminescence-- why is this phenomenon so mysterious?

  1. Feb 27, 2015 #1
    I'm not sure which forum to post this under...

    Anyhow all scientists I've talked to have agreed that sonoluminescence is not completely understood by the scientific community. I'm curious as to which parts of the phenomenon remain a mystery.

    To me it seems like a reasonable process if you accept that pressure waves in a fluid can cause bubble cavitation. Bubbles grow to a critical size, then implode rapidly causing a region of high pressure and high temperature. This excites electrons near the bubble collapse zone, and when these electrons return to their ground state they emit photons. What am I missing here?
