Abstract
Sonoluminescence is the light produced from the collapse of bubbles in water under ultrasound. Schwinger proposed a physical mechanism for sonoluminescence in terms of photon production due to changes of quantum electrodynamic energy contained in a collapsing dielectric bubble. However there are critics for the Schwinger’s proposal that his estimate of the Casimir energy involved is inaccurate and there are several papers to propose its missing term. In this paper, the author presents another possible component of sonoluminescense which is due to Cherenkov radiation from tachyon pairs generated in a collapsing bubble.

Cavitation is the formation of vapor bubbles of a flowing liquid in a region where the pressure of the liquid falls below its vapor pressure
As the properties of sonoluminescence which releases too large an amount of energy and releases the energy on too short a time scale are consistent with the vacuum energy explanation, Schwinger proposed a physical mechanism based on the instantaneous collapse of a bubble for sonoluminescence in terms of photon production due to changes of quantum electrodynamic energy contained in a collapsing dielectric bubble [4]
One of them was a proposition given by Claudia Eberlein [9,10] that sonoluminescence could be explained in terms of quantum vacuum radiation by moving interfaces between media of different polarization, which might be alike to the Unruh effect. Instead of their conventional quantum electrodynamic (QED) ideas for the explanation of sonoluminescence, the author tries to present another component of sonoluminescense, which is due to the Cherenkov radiation from tachyon pairs created from the zero-point fluctuations of electromagnetic field (ZPF field) contained in a collapsing bubble
Summary
Cavitation is the formation of vapor bubbles of a flowing liquid in a region where the pressure of the liquid falls below its vapor pressure This is a process in which a void or a bubble in a liquid rapidly collapses and producing a shock wave to cause a temperature increase and emits light. One of them was a proposition given by Claudia Eberlein [9,10] that sonoluminescence could be explained in terms of quantum vacuum radiation by moving interfaces between media of different polarization, which might be alike to the Unruh effect Instead of their conventional quantum electrodynamic (QED) ideas for the explanation of sonoluminescence, the author tries to present another component of sonoluminescense, which is due to the Cherenkov radiation from tachyon pairs created from the zero-point fluctuations of electromagnetic field (ZPF field) contained in a collapsing bubble
