Paul Dirac argues that when one encounters large, dimensionless numbers of very high value in physics, such as 10^40 or 10^80, it is very unlikely that they are not connected to each other. He maintains that it is likely that there is a mathematical law of nature, not yet discovered, that binds them. This is the so-called Dirac Large Number Hypothesis. In particular, it refers to the age of the Universe, t, the speed of light, c, the mass of the electron, me, the mass of the proton, mp, and Newton’s universal gravitational constant, G. According to Dirac, we have: ct/(e^2/me*c^2) = 10^40 = e^2/(G*me*mp) = SQR(c^3*t/(G*mp) = k*t
