The mechanism of sonoluminescence is not properly understood by anybody but it is known that tiny bubbles erupt and collapse in the liquid and in the process of collapsing, a flash of light is given off. Whatever the case, this implies that there is also an associated electromagnetic pulse. An eminent scientist recently described the process as follows (and I would suggest that the Internet link given below is essential reading):

"The nature of sonoluminescence is still unclear. Most intriguing is the possibility that it is a release of zero-point energy via some kind of Casimir-like process. Recently there were measurements published indicating that it might involve nuclear reactions. Then again, it may be a high temperature shock phenomenon. My guess is that sonoluminescence will indeed prove to be highly significant and indicative of potentially useful new physical processes. See http://www.calphysics.org for some discussion of zero-point energy physics." |
