We now have a well established standard model of cosmology that agrees with virtually all cosmological observations regardless of the method or the object under study. The model indicates that the universe today comprises 5% atoms, 23% dark matter, and 72% dark energy. The model assumes a geometrically flat universe, but is robust to relaxing this assumption. The model is based on physics of the Universe at 10-35 sec, and makes testable predictions directly linked to physics of that epoch. For example it predicts that primordial gravitational waves should be traversing the cosmos. In this talk, we review the foundations of the standard model with an emphasis on what we can tell from the cosmic microwave background (CMB) radiation. We discuss the observational forefront and what we hope to learn over the next few years.
