pending issues in quantum mechanics

Pending issues in quantum mechanics involve understanding how particles behave and interact at the smallest scales. Key questions include how to reconcile quantum theory with gravity, why wave functions collapse during measurement, and whether hidden variables determine outcomes. Scientists also seek a unified framework that explains phenomena like entanglement and superposition consistently. These problems challenge our grasp of reality, space, and time, and solving them could revolutionize technology and deepen our understanding of the universe. Despite extensive progress, these foundational questions remain open, making quantum mechanics a vibrant area of ongoing research.
