Abstract: Abstract An abiding issue in cavitation science is the focusing of energy by the collapse of a gas bubble in water. In particular, one would like to understand the origin of the flash of light ('sonoluminescence') that accompanies bubble collapse1. Hilgenfeldt et al.2 have presented a simple explanation for this light emission, based on a hydrodynamic (Rayleigh–Plesset) analysis of bubble dynamics. Here we argue that their model is too simple, on the grounds that it cannot account for some well-established observations and that it involves the application of this hydrodynamic equation outside its range of validity.
