The Marvels of Space-Time
Sep 20, 2023
Physicist Max Tegmark, J. Gott, Juan Maldacena, Fotini Markopoulou, and philosopher John Leslie explore the interconnectedness of space and time as part of the same entity. They discuss the challenges of reconciling quantum theory with the continuous nature of space in general relativity. The podcast also delves into the cosmic particle smashing nature of the early universe, challenges the notion of the disappearing past, and contemplates the intricate relationship between space and time as active participants in reality.

Space-time: The Active Participant in the Universe
Einstein's theory of relativity transformed our understanding of space and time. Space-time is not just a static backdrop, but an active participant in the universe. It can shake, curve, and stretch. Gravitational waves are ripples in the fabric of space-time, and the universe's expansion indicates that space-time is dynamic. The challenge lies in reconciling the continuous space-time of general relativity with the discrete nature of quantum theory. Quantum gravity, which could be explored through studying the early universe, may provide clues to understanding the fundamental nature of space-time.
