Is Gravity Quantum? New Study Complicates Feynman's Entanglement Experiment

Unifying gravity and quantum theory is one of the biggest challenges in physics. Richard Feynman proposed an experiment to test if gravity can entangle massive objects, which could prove its quantum nature. But a new study in Nature suggests it's not that simple. Researchers found that classical gravity can also generate entanglement, making Feynman's experiment less conclusive. This video explains the study's findings, the role of quantum field theory, and what it means for our understanding of quantum gravity. Is gravity truly quantum?
