Jonathan Richardson
Ph.D. candidate, Department of Astronomy & Astrophysics

I am a fourth-year graduate student in the Department of Astronomy & Astrophysics at the University of Chicago. I work with Stephan Meyer and Craig Hogan on the Fermilab Holometer, a laser interferometry experiment designed to explore the fundamental nature of space-time with unprecedented precision.

Our understanding of physics breaks down on distances smaller than 10-35 m or over time intervals shorter than 10-44 s. Below this quantum threshold, known as the Planck scale, space and time lose all classical meaning. The Holometer is searching for evidence of a new type of quantum position uncertainty originating from this scale, whose existence would imply a fundamental limit on the information content of space-time. No experiment to date would have been sensitive to this ultra-faint effect. A detection would open an experimental pathway toward understanding Planck-scale unification and quantum gravity.
