Topic: "Dark Matter, Dark Energy, and Inflation"  (Video)

ABSTRACT: The standard cosmological model seems to be able to account for all cosmological observations.  But its three basic ingredients, dark matter that holds together cosmic structures, dark energy that drives the universe in ever increasing expansion, and inflationary   perturbations that provide the seed perturbations for all we see   around us, are complete mysteries.  In the talk I will highlight  what we don't know about the cosmological standard model.
