An Orbiting Disco Ball Just Gave Einstein's Theory of Gravity Its Most Precise Test Ever
Ars Technica·Monday, 13 July 2026

Scientists used a small, reflective satellite — described as an orbiting disco ball — to conduct the most precise test yet of Einstein's general theory of relativity. The experiment confirmed that even Earth's relatively modest mass distorts space-time, as Einstein predicted. The results set a new record for precision in testing the theory.
Why It Matters
General relativity underpins GPS, satellite navigation, and much of modern physics. More precise confirmations help scientists trust — and build on — the theory for future technologies.
