| contents | <p>Sonoluminescence—the emission of light from collapsing acoustic bubbles—has resisted a complete mechanistic explanation for nearly a century. This paper proposes a reframing: sonoluminescence is not a byproduct of secondary processes within the bubble but a direct conversion of acoustic energy to electromagnetic energy, mediated by the geometric collapse of a spherical cavity that eliminates the spatial modes available for mechanical wave propagation. The bubble functions as an engine: the gas mass and the volume it occupies define the system’s energy-processing capacity—its displacement—while the acoustic wave provides the driving energy. The mass is not consumed in the conversion; it persists unchanged across millions of cycles, serving as the working fluid through which acoustic energy is channeled into electromagnetic radiation. The incompressible liquid surrounding the bubble seals every mechanical and thermal exit, making radiation the path of least resistance. This framework unifies sonoluminescence with sonic booms under a single principle: wave-stacking through medium-propagation mismatch, with boundary conditions determining whether the output is amplified sound or light. A testable prediction is presented: the photon output per flash should scale with the mass and volume of gas in the bubble, which together define the energy throughput capacity of each compression cycle.</p> |
