The Emergence of Space-Time and the Search for Quantum Gravity
31:30 - 39:31 (08:00)
The discussion explores the idea that space-time is an emergent phenomena and may not be fundamental, and how finding the right completion or extension of quantum mechanics would incorporate space-time and gravity.

Theories of space, time, gravity and cosmology can be described by general relativity, whereas quantum theory describes the behavior of little things.
31:30 - 33:44 (02:13)
Summary
Theories of space, time, gravity and cosmology can be described by general relativity, whereas quantum theory describes the behavior of little things. The right extension or completion of quantum mechanics would be one that incorporates space-time and gravity, bringing together the two theories.

Summary
The concept of space-time is an intellectual construction that emerges from our understanding of the universe's events. While space is the location of things, time is viewed as the continual creation of events from existing ones.
