Original: "Ruling out nonlinear modifications of quantum theory with contextuality"
Nonlinear tweaks for quantum gravity could extinguish contextuality, making the cosmos classical and predictable.

Some theories that merge quantum mechanics with gravity make the rules nonlinear. But a new study shows this could erase contextuality—the strange feature where a particle's properties don't exist until measured. If experiments keep showing contextuality, those gravity-inspired modifications are dead. It’s a clean test for quantum gravity.
🎯 The Schrödinger-Newton equation imagines that every particle is pulled by its own gravity, which would make large objects collapse into one location, explaining why we never see a basketball in two places at once.
🎬 Nonlinear quantum mechanics forcing collapse mirrors the famous Schrödinger's cat, and resonates with films like 'Coherence' where parallel realities clash and merge.
