Proton Shrink in size

"The proton seems to be 0.00000000000003 millimetres smaller than researchers previously thought, according to work published in today's issue of Nature." in Nature.com

The research made at the Max Planck Institute of Quantum Optics in Garching, Germany. Counted with Portuguese scientist effort from Coimbra University and Aveiro University.

The difference is so infinitesimal, but the new measurements could mean that there is a gap in existing theories of quantum mechanics.

There's three questions about this problem, one of them is the answer:

a) the theory (QED[1]) is incomplete and there's something that it cannot foresee;

b) the calculus[2] are wrong;

c) the Rydberg's constant[3] value is wrong .

[1] QED - Quantum Electrodynamics describes the interactions between light and matter and is one of the most successful in predicting the properties of atoms.

[2] The calculations are those who, from that theory, allow to calculate the size (radius) of the proton, one of the basic constituents of atoms.

[3] Rydberg constant whose value is also linked to the size of the proton.
