An international researchers has found evidence that a universal constant in nature which governs the strength of the molecular bonds between atoms - called alpha - might have changed over time. The strength of alpha is very important, and life couldn't exist if it was much different from its current value. ... Gravity Constant...

The universal gas constant is the constant R appearing in the ideal gas law PV=nRT, where P is the pressure, V is the volume, n is the number of moles of gas, and T is the temperature. The universal gas constant is defined in terms of Boltzmann's constant k as R \equiv kN_A, where N_A is Avogadro's number.

In physics, there are a host of standard constants: the speed of light, the charge-to-mass ratio of the proton, and Planck's constant, to name just a few. Repeated measurements going back a few hundred years have shown that these items are indeed constant.
