The Center's active work sits in three research areas. A program moves to this page once the question it was built to answer has been answered. Nothing listed here is withdrawn. Preprints stay on the publications page, reference data sets keep their persistent identifiers, and the repositories stay public.

General relativity computes time dilation from a known gravitational source. This program ran that calculation backwards and recovered the source from the measured dilation. It finished on that result: the geocentric gravitational constant GM, taken directly from Galileo satellite clock data to a median precision of 4 × 10−7. The recovery covered more than a million measurements, was cross-checked on a second satellite, and used no external mass input.
