In 2014, artist Olafur Eliasson and filmmaker Claire Denis connected for the first time to explore and discuss their common fascination with phenomena that have not yet been fully explained by science – such as black holes – and their shared interest in abstraction. This short film by Denis, contemplating tests for Eliasson's work ‘Contact’, is one outcome of that conversation which would eventually lead to their collaboration on Denis's film High Life (2018), in which Eliasson designed the light installations at the films end.
