“Earlier this year, Dr. Sabine Hossenfelder, a theoretical physicist in Stockholm, made the jarring suggestion that the dark matter all around us—unseen particles that neither emit nor absorb light—might cause cancer. I wanted to have the darkness behave in the manner light does when shining through a window, so I built up several very thin glazes of dark paint to keep the translucency of the invented dark light.” 11 × 12, acrylic and oil on paper.
