The Story of Spacetime - From Galileo to Quantum Gravity

Embark on a captivating journey through the evolution of our understanding of spacetime in this 37-minute lecture by Professor Fay Dowker at The Royal Institution. Explore the intricate relationship between general relativity and Newtonian physics, tracing the path from Galileo's groundbreaking ideas to cutting-edge research on the granular nature of spacetime. Delve into concepts such as outer and inner space, falling objects, celestial mechanics, and Newton's theory of gravity. Examine the criticisms of Newtonian theory and contemplate the nature of time and the concept of a global moment of now. Gain insights into the fascinating world of theoretical physics and quantum gravity from an expert in the field, as Professor Dowker shares her research on the hypothesis of atomic spacetime.
