From a physics perspective, it's long been assumed that the fundamental constants and the laws of nature really are the same everywhere and at all times. However, one particular dimensionless constant ...

Physical quantities such as the speed of light, the gravitational constant and the electron mass are believed to be the same independent of where and when they appear in the universe. Therefore, they ...

The dynamics of fundamental constants in cosmology concern the possibility that dimensionless parameters of nature—such as the fine-structure constant (α), the proton–electron mass ratio (μ) and the ...
