Past physics theories introduced several fundamental constants, including Newton's constant G, which quantifies the strength of the gravitational interaction between two massive objects. Combined, ...
Relative changes with redshift of the fine structure constant (Credit: ESO) Detecting or constraining the possible time variations of fundamental physical constants is an important step toward a ...
Detecting or constraining the possible time variations of fundamental physical constants is an important step toward a complete understanding of basic physics and hence the world in which we live. A ...
