100 000 000 d'années après le Big Bang
Sonification and visualisation of the Big Bang theory
In the 1960s Arno Pensias and Robert Wilson accidentally discovered cosmic background radiation. It is during research on communication with artificial satellites that they discovered the presence of a radio signal from the depths of the universe. This signal is in a way the residue of the energy emitted by the Big Bang. Since then, the mapping of the cosmic background has revealed microscopic variations in temperature. These variations confirm the theory of the Big Bang. In extrapolating beyond the cosmic background, scientists created a chart of the Universe’s evolution. Among other things this chart shows the evolution of the temperature, dimension of the horizon and the emergence of matter.
100 000 000 d'années après le Big Bang is video-sound installation that makes use of data. To make it I created an animation system comprising a camera, a VBR 64 LED matrix, an Arduino platform and Processing software. Image by image, the software modifies the colour and intensity of the LEDs and recreates the proportions of the Big Bang on a tiny scale.
The soundtrack was created according to the same procedure, but the interface now controls synthesizers. The chart and the spreading of the Big Bang here becomes a musical score.
