The <Rayleigh-Plesset equation> balances the radial inertia of an incompressible liquid around a spherical bubble against internal and ambient <pressure>, <surface tension> and <viscous stress>. Removing the last two effects and setting the bubble pressure to zero gives the following vacuum-collapse case.
