Measurement begins on a stormy late afternoon in a basement lab at the Case School of Applied Science, just outside Cleveland, Ohio.
Michelson and his wife are seated around an interferometer — Michelson’s invention to measure the aether’s effect on the speed of light, pictured above — as he prepares for the last of his experiments. All the others have failed.
Friends and family interact, both in the lab and at home, as everyone awaits the beginning of the test.
Then the story jumps ahead in time, sometimes to the near future, and other times well into the 20th century, and those family members and friends reveal what happened through who, and what, they’ve chosen to measure.
The story ends back where it started, with the experiment about to begin….or continue.
