SINKING THOUGHTS | 2019 | installation
Laser-lit clouds of submillimetre soap bubbles embracingly trace the air flow around an orifice. At a certain distance from the inhaling hole a horizon forms, separating the flow between inbound air and the rest of the substrate. Once the bubbles traverse this vacillating boundary they become entrained filaments that plummet inward. Besides tracing vortical motion, these luminous bubble trajectories lay bare a phenomenon known as the Coandă effect: when a fluid jet traverses an orifice it tends to follow adjacent surfaces and to entrain surrounding fluid so that a low pressure region emerges along the surface. Though named after a 20th century inventor who exploited the phenomenon for airborne hovercraft technology, the original discoverer was Thomas Young in 1800 – a year before his legendary double-slit experiment.
Sinking Thoughts envisions the imminent elucidation of a black hole’s interior, where not only space-time but also its underlying qubits of information might become irreversibly warped. Alternatively, the information crossing an event horizon may remain intact, if it is quantum teleported through a wormhole throat. "The interaction between the boundaries implies that the radial direction is effectively a compact circle" [P. Gao, D. Jafferis, A. Wall, "Traversable wormholes via a double trace deformation", Journal of High Energy Physics 17(2017)151].
Sinking Thoughts was created in collaboration with the Crossing Parallels programme and physicist Fulvio Scarano at Aerospace Engineering, TU Delft. Scarano has pioneered the development of a helium-filled soap bubble system to profusely seed the air stream in large-scale wind tunnels. Enabling high-repetition rate tomographic PIV (particle image velocemitry), the system has significantly enhanced the measurement of three-dimensional velocity and vorticity, as well as aerodynamic forces and loads.
