The paper presents a large numbers hypothesis (LNH) prediction wherein large dimensionless numbers of equal magnitude are taken as precisely equal to predict the proton half life. This prediction is based on Dirac's hypothesis (1938) that since large dimensionless numbers in physics and cosmology are all simple powers of approximately 10 to the 40th power, it is reasonable to suppose that they are simply related. The prediction given here can be both tested and ruled out by experimental evidence, and is based on the recent development of grand unified theories of the electro-weak and strong interactions which provide a theoretical estimate of the proton lifetime. These theoretical results are connected to the LNH by deriving an expression for the proton lifetime using the standard results of general relativity.
