  Within spacetime, the separation between two events is measured by the invariant interval between the two events, which takes into account not only the spatial separation between the events, but also their temporal separation.
  Invariant Interval is shaped by gravity, the specific interval structure (created with the aluminum collars), and the material properties of the steel and glass beads. The sculpture is also about the physical process of expansion. The sculpture starts out as a flat object, and expands out to it's final form creating a large volume with very little mass.
