Quantum Gravity

Quantum Gravity seeks to merge General Relativity with Quantum Mechanics—a challenge that has resisted physicists for decades.

🧠 My Interpretation

To me, quantum gravity feels like building a map for a place we’ve never been. We know the ingredients—quantum uncertainty and curved space—but don’t yet have the recipe.

🧩 Major Approaches

• Loop Quantum Gravity: Spacetime made of discrete loops—quantized geometry.
• String Theory: Everything is made of tiny vibrating strings in higher dimensions.
• Holography: The universe might be a projection from lower-dimensional information.
• Emergent Gravity: Gravity may arise from entanglement and thermodynamics.

It's not just about combining theories—it’s about redefining what space, time, and existence are.
