Eclipse expeditions in 1919 measured the apparent displacement of stars near the Sun and were interpreted as supporting Einstein’s predicted gravitational deflection of light.
The 1919 data were historically influential but less precise than later radio and optical measurements of light deflection.

This is an authored directed relation from the source endpoint to the target endpoint.
The measured deflection was interpreted as supporting the relativistic prediction; later experiments provide much higher precision.
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.
