Singularities: Of Primordial Black Holes translates gravitational lensing into a physical, optical encounter through a sculpture with a silicon wafer at the center of it. The wafer is encoded to show the Hawking Radiation dispersion from a primordial black hole of the mass of the silicon wafer, and uses nano etched grated nanostructures to manipulate light in ways that echo how spacetime curves around celestial objects through the observer.
On the wafer, the etched field functions like a sculptural lens. Sub-wavelength patterns steer phase, amplitude, and polarization so that reflected or transmitted light forms distortions that resemble strong- and weak-lensing signatures. As viewers move, the patterns answer with parallaxing shears, arcs, Einstein-ring like halos, and caustics that thicken or thin with angle and distance. The viewer’s motion becomes the stand-in for a traveling photon and the wafer’s surface becomes a navigable section of curved spacetime.
The nano-etched 6” silicon wafer is experienced indirectly, through a large concave mirror that turns the wafer into a floating, magnified, kinetic apparition. The wafer is mounted on the end of a slender black metal rod, positioned 300 mm in front of a 600 mm diameter concave mirror. When a viewer stands in front of the mirror and looks toward its center, they do not look at the wafer itself but at a virtual image: a magnified, suspended disc of nano-lensing texture that hovers optically in front of the wall.
