The Last Scattering is a collaborative work produced by New York based artist Matthew Ritchie and the Director of Arup's Advanced Geometry Unit, Daniel Bosia. The result of this collaboration is an object that straddles the fields of sculpture, architecture, mathematics and engineering.

Taking a moment in universal history as its starting point, The Last Scattering refers to the moment when light separated from matter, less than 400,000 years following the Big Bang. Evidence of the Last Scattering, otherwise known as cosmic background radiation, persists as the static visible on television screens.

Ritchie took the Last Scattering as the subject for his work, because, for him, it functions as a sort of horizon line, representing the moment when the universe snapped into being. Working together with Bosia, the pair produced a work which represents structure, both on a molecular and universal scale. The Last Scattering is both repetitive and mathematical whilst employing change and difference. Thus representing the underlying notion of the structures of the universe, which despite their grand nature, are often the result of intricate molecular structures.
