Protons - smaller than we thought
The proton – one of the smallest building blocks of all matter – is even smaller than previously assumed. As a consequence of this discovery, a correction will have to be made to either the quantum theory of how light and matter interact or to the value of the Rydberg Constant – i.e. an important change is needed to either the most precise theory in physics or the most precisely determined physical constant.
