Physicists Say the Proton Radius Puzzle May Finally Be Settled
Key Takeaways
- Two new experiments support the smaller proton size first flagged in 2010.
- Both studies used hydrogen atoms and laser-controlled electron transitions.
- The measurements point to a proton radius of about 0.84 femtometres.
- A firmer proton radius could improve future precision tests and searches for new particles.
