  • Summary

    Computer simulations have played a crucial role in modern cosmology, a role anticipated and pioneered by F. Hoyle. Their interrelation with theory and observation is invaluable in developing theoretical positions, testing general features of isotropy and homogeneity at various scales, and probing the anomalies. The simulations also make up for the inability to experiment with different structures of the universe and substantially different physical universes. Yet various selection effects and the numerical intractability of certain alternative explanations limit the value of simulations. This is a serious epistemic worry that can be addressed with the lessons learned from the alternative explanations of the CMB.
