The Biggest Ideas in the Universe is a series of videos where I talk informally about some of the fundamental concepts that help us understand our natural world. Exceedingly casual, not overly polished, and meant for absolutely everybody. This is the Q&A video for Idea #21, "Emergence." I took the opportunity to just give a mini explanation on the work I and others have recently been doing on understanding the emergence of spacetime.
