High frequency sound waves propagate through a water-filled cylinder, prompting naturally diffused air bubbles to implode. While tracing the motion imparted by sound waves, these implosions are accompanied by shock waves, jet formations, temperatures as high as are found on the Sun, and conjecturably, quantum vacuum radiation. Implosion Chamber is a new exploration of the multifold phenomenon of acoustic cavitation, which the duo has been pursuing for over a decade since the creation of Camera Lucida: Sonochemical Observatory. All acoustic vibrations generate oscillating vacuums. If the wavelength is short enough, and the amplitude is high enough, these pockets of emptiness can incite the formation and implosive collapse of micro-bubbles in a liquid. The bubbles “appear by tearing the liquid with brute force (ultrasound for example). Because they are essentially empty, they are termed cavitation bubbles, i.e.,just cavities.” [Lauterborn et al., Advances in Chemical Physics, Vol 110, Prigogine and S.A. Rice, eds.:Wiley 1999]. With the sudden appearance of a cavitation bubble, a tremendous difference in pressure arises between its nearly vacuous interior and the surrounding fluid. Consequently, the bubble rapidly implodes under the liquid’s pressure (at over four times the speed of sound), and its gaseous innards shrink into a core so dense that the temperature rises up to 10,000 C. Initially conceived as an environment for visually perceiving sound in three dimensions, Implosion Chamber plunges deep into the paradoxical origin of all vibrations: the ubiquitous vacuum. The trillion-fold energy amplification that occurs during acoustic cavitation could only be possible by tapping into the unbridled power of emptiness. What appears to be empty, motionless and infinitesimal, is upon closer inspection an inexhaustible sea of energy.
