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 Idea #4, "Space." We talk about what is meant by three-dimensional space, why it might be three-dimensional, and why space exists at all. Why do we live in position space, rather than in momentum space, anyway? And what's so important about "locality"?
