Program to generate toy universes with different values of four physical constants. Note the emphasis on "toy." This is a very simple program that makes no attempt to generate a universe in detail. Its main purpose is to demonstrate that long-lived stars, which are probably required for the evolution of life, does not depend on some "fine tuning" of the constants of nature but occurs for a wide range of parameters. It also shows that the large number coincidence first proposed by Weyl is not uncommon.

Note that the weak interaction strength has not been included as a parameter. Also, the effect of strong interaction strength is not included in the calculation of astronomical quantities, although it does come in for the large number coincidence. While the gravitational strength does not appear as a parameter, it is varied through variations in the proton mass. For more details see the Philo paper below.

I have used equations from "Dependence of macrophysical phenomena on the values of the fundamental constants: by W.H. Press and A.P. Lightman, Phil. Trans. R. Soc. Lond. A 310, 323-336 (1983).
