Vibrations

'Vibrations' (2016) is a video triptych exploring the generation of audio frequency from galactic gas density represented through the electromagnetic spectrum. It does so through a process of mapping audio frequencies (measured in hertz) to their visibility on the electromagnetic spectrum. The spectrum, which describes all wavelengths of light from gamma rays to radio waves, represents the density buildup and movement of galactic gases in giant molecular clouds and nebula.  The computational models utilized in the series were produced by researchers at NASA, the University of California Berkeley and the University of Leicester.

Vibrations #1 generates audio frequencies based on a simulation of the evolution of a giant molecular cloud (GMC) from 350,000 years to 700,000 years. It illustrates a gravitational collapse leading to the formation of an infrared dark cloud (IRDC) filament in which protostars begin to develop, as shown by the bright luminosity along the main and surrounding filaments. The collision region of the main filament with a nearby dark cloud produces multiple stars, resulting in a protostellar cluster. Vibrations #2 generates audio frequencies based on an illustration of a star formation from the collapse of a molecular cloud. The star collapses, under its own weight, resulting in the formation of new stars. Swirling discs of gas surround a number of the new stars. In certain areas, gravity pulls the gas together to form a dense core. Vibrations #3 generates audio frequencies based on the documentation of the Veil Nebula by the Hubble Space Telescope in 2015. It illustrates gas as a thin, rippled surface and the emission from different chemical elements which rise from different layers of gas within the nebula. The emission from Sulfur, Hydrogen, and Oxygen are indicated in red, green, and blue, respectively.

 

Sound and light share the dynamic element of vibration. Vibrations (2016) examines this commonality through the generation of audio frequency from computation representation of matter which is visible on the electromagnetic spectrum and not to the human eye.
