- Physicists think they've resolved the proton size puzzle
Physicists have resolved a 15-year debate over the proton's charge radius, with recent experiments favoring a smaller radius over new physics. Studies published in Nature and Physical Review Letters suggest the proton radius puzzle is settled, aligning with quantum mechanics rather than the outdated Bohr model.
