Every hour, a dead star listed by space institutions (NASA and ESA) is printed on a special sheet of paper, thanks to a printer connected to their databases. This photo is then placed in a tub of water, and the paper, created with the help of physicists, expands. Like the expanding universe, it then changes shape thanks to the artist's gestures, forming various constellations, until its complete atomic dissolution. This process is then broadcast in positive on a small video screen. Then in negative, in deferred time, on a large projection in the exhibition space. The death of a star, a very long phenomenon on an astronomical scale, is thus transposed within reach of human perception.
