"Breakthrough Discovery: New Insights into the Proton Unveiled by Physicists"

Physicists have used 50-year-old predictions about gravity's impact on subatomic particles to measure a second mechanical property in the proton, revealing the shear stress on the proton's quarks. By exploiting decades-old data and deeply virtual Compton scattering, the team successfully measured the strong force's distribution within the proton, providing insights into the proton's structure and potential for discovering new physics.
