Explore the nature of time in this thought-provoking World Science Festival panel discussion. Delve into the evolution of our understanding of time from Newton's absolute concept to Einstein's revolutionary theory of relativity. Examine how recent developments in string theory and quantum gravity challenge our fundamental notions of space and time. Join renowned experts as they debate whether time is a fundamental aspect of reality or an emergent property. Investigate topics such as special relativity, loop quantum theory, and the relationship between time and space. Consider the practical implications of understanding time and ponder whether these inquiries fall within the realm of physics or metaphysics. Gain insights into cutting-edge research, including studies on black holes, that continue to shape our comprehension of time and the universe.
