What is the name of the limit that was named in honour of the person who was honoured by having the number that represents the number of protons named after him?
Eddington number In astrophysics, the Eddington number, "N", is the number of protons in the observable universe. The term honors the British astrophysicist Arthur Eddington, who in 1938 was the first to propose a value of "N" and to explain why this number might be important for physical cosmology and the foundations of physics.
