Gravity Seems Holographic. What Does That Mean for Reality?
Physicists propose that gravity could be a holographic phenomenon, meaning it emerges from information encoded on a lower‑dimensional surface rather than acting as a fundamental force. The idea builds on the holographic principle, suggesting space‑time and gravitational effects arise from quantum data at the universe’s boundary. Researchers explore implications for unifying quantum mechanics with general relativity and for understanding reality’s underlying structure.
