This sculpture depicts gravitational lensing by dark matter. The cause of lensing is represented here by a cluster of
Möbius strips, the subtle aspects of which allude to not-yet-understood properties of dark matter. Installed at the
East Lansing MI High School, the sculpture honors the sustained achievements in physics education by John
Plough and colleagues. It is intended to remind students of the many unsolved problems in astrophysics and
cosmology that remain to be attacked by new generations of scientists. This sculpture was created by Jens Zorn,
Professor of Physics at the University of Michigan.
