How Old Is It | 03 - Big Bang ΛCDM Cosmology (4K)
We begin with the discovery of the Cosmic Microwave Background (CMB) radiation. We cover Recombination, Decoupling, and the Surface of Last Scattering that created the CMB.

We examine the nature of the CMB temperature Anisotropy and how, through a process known as Caustics, it lead to galaxy filaments and great voids. This analysis includes Cold Dark Matter. We then cover Vacuum Energy, the Casimir Effect and Dark Energy. We then cover the observational evidence for an Accelerating expansion. We then go beyond the surface of last scattering to Neutrino Decoupling, Nucleosynthesis, Baryogenesis and Cosmic Inflation. We summarize with a review of the cosmic time line, and conclude with a look at current and future cosmology research.
