- 8Hacker News·9/25/2026researchGravity May Be Holographic, Rethinking Space and Reality
The article explains the holographic principle and the AdS/CFT correspondence, which suggest that the information inside a volume of space can be fully encoded on its boundary. It argues that these ideas have become central in theoretical physics and may reshape how scientists think about gravity, quantum mechanics, black holes, and the nature of space itself.

The article explains how a pen plotter can be used to create hand-etched hologram-like images by drawing reflective ridges whose curvature controls how highlights move. It builds the idea from intuitive optics, showing how the technique can render depth without traditional holography equipment.
