Ⅸ: Is Reality a Lower-Dimensional Projection?
The information describing a volume of space may be entirely contained on its boundary surface. This article examines where that idea came from, what the AdS/CFT correspondence established, and what it implies about the nature of space, gravity, and information.

Ⅷ: Singularities
What are singularities? How do they form from the death of stars? What are the types general relativity predicts, and what do the three leading approaches to quantum gravity each propose as a resolution?

Ⅶ: Is Spacetime Discrete?
Is spacetime smooth and continuous, or does it have a fundamental granular structure? This article examines the theoretical and experimental evidence for spacetime discreteness.
