Video: Cosmology from Ancient Greece to Today
This lecture from the Library of Congress features NASA's Michelle Thaller as she outlines the history of inquiry into the nature of the universe
Probably every culture on Earth has had an answer to the question “What is all this, and why?” Today, the majority accepted explanation for the nature of our universe is derived from scientific observation. But the idea of an interconnected space-time expanding over billions of years is just the latest theory in the history of cosmology. Besides countless myths, legends, and religious tenants, the scientific model of the universe is the product of scientists and philosophers building on each other’s work for thousands of years. The story of how humans have come to terms with their reality is perhaps just as important as the science itself.
This lecture from the Library of Congress features Michelle Thaller, assistant director for science communication and higher education at NASA's Goddard Space Flight Center. She outlines the history of inquiry into the nature of the universe, beginning with the philosophers of Ancient Greece up to the modern day. It’s a great summary for anyone who's ever looked up to the stars and wondered about the big picture.
