An orbiting disco ball gave Einstein’s theory its most precise test yet

Scientists have achieved the most precise measurement of the Lense-Thirring effect, or frame dragging, using a specialized satellite called LARES-2. This experiment confirms a key prediction of Einstein’s general theory of relativity regarding how rotating masses distort space-time.
Why it matters
Validating fundamental physics theories with high precision deepens our understanding of the universe's structure and the nature of gravity.

The report is a straightforward summary of a scientific achievement and its methodology.
