Thoughts on Dark Matter, Dark Energy, Inflation

Remarkable observational results and bold theoretical ideas have resulted in a standard cosmological model. This model, the `Lambda-Cold-Dark-Matter' model seems capable of precision predictions of many cosmological observables. However the model posits the existence of dark matter, dark energy, and an early inflationary period. We know nothing about the nature of these three ingredients.
