The Whisper of Creation: Unveiling the Cosmos with Dr. Harold Williams

Join Dr. Harold Williams from Montgomery College Planetarium as he explores the mysteries of the universe in "The Whisper of Creation." Delve into groundbreaking discoveries made by instruments like the Cosmic Background Explorer (COBE) and the Wilkinson Microwave Anisotropy Probe (WMAP), which have shaped our understanding of the cosmos. Learn about the universe's age, temperature, and structure. Discover how cosmic background radiation reveals insights into the universe's flatness and the Hubble constant, illuminating our place in the vast cosmos.
