Cosmology in the 21st Century

Embark on a cosmic journey through the expanding universe in this public lecture by cosmologist Kendrick Smith. Explore the evolution of the cosmos from the big bang to our current understanding of dark matter and other celestial phenomena. Delve into topics such as the Doppler effect, redshift surveys, relativity, Hubble's observations, and the implications of an expanding universe. Uncover the mysteries of gravitational instability, dark ages, and the Cosmic Microwave Background. Examine early plasmas, cosmic fingerprinting, and spectral analysis. Investigate dark matter halos, dark energy, and ponder the ultimate fate of the universe. Learn about the Big Bang theory, inflation, and quantum mechanics. Gain insights into the composition of the universe and the CHIME project. This comprehensive tour of modern cosmology offers a fascinating glimpse into the cutting-edge research and theories shaping our understanding of the cosmos in the 21st century.
