In conventional science, the Fundamental Constants of Nature are considered invariant physical quantities, fundamental (cause-indipendence), universal in nature (space-indipendence) and constant in time (time-independence). They are used in the basic equations that describe the fundamental physical phenomena. They can be dimensionless, or can have dimensions.
The constants that are considered fundamental are the following (the set of constants varies according to the theoretical reference framework considered):
- the gravitational constant G
- the velocity of light in vacuum or speed of light (c)
- the Planck constant (h) or (h bar)
- the electric constant ε0
- the charge of the electron
- the absolute value of which is the fundamental unit of electric charge (e)
- the mass of the electron (me)
- the dimensionless fine-structure constant, symbolized by the Greek letter alpha, which characterizes the strength of the electromagnetic interaction
- the Avogadro constant (NA)
- the Boltzmann constant (kB)
- 9 Yukawa couplings for the quarks and leptons (equivalent to specifying the rest mass of these elementary particles),
- 2 parameters of the Higgs field potential
- 4 parameters for the quark mixing matrix
- 3 coupling constants for the gauge groups SU(3) × SU(2) × U(1) (or equivalently, two coupling constants and the Weinberg angle)
- a phase for the QCD vacuum
