The Rydberg constant is a fundamental constant that is one of the most precisely known constants in physics, containing 12 significant figures with, previously, a relative uncertainty of about two ...

Despite nearly a hundred years of astronomical measurements and calculations, scientists still can’t agree on the exact value of the Hubble constant. The true number could reveal missing pieces in our ...

The gravitational constant, denoted as G, is a fundamental quantity in physics that describes the strength of the gravitational force between two masses. Accurately measuring G has been a ...

The Brazilian researchers claim that the number of fundamental constants depends on the space-time in which the physical quantities are considered. They analyze two types of space-time ...
