The C(12)+C(12) => Ne(20)+He(4) fusion reaction rate is shown to be extremely sensitive to variations in the strong coupling constant. Connection with the strong coupling constant is established by using the one boson exchange potential for the nuclear forces and then relating the meson masses and coupling constants of this model to QCD. The implications of a cosmological evolution of these constants on carbon burning in Type 1a Supernovae are discussed.
