What are the unsolved problems in physics?
And here is its answer: Physics, despite its immense progress, is still grappling with numerous unsolved problems. These challenges span various domains, from fundamental theoretical frameworks to practical experimental observations. Here’s an overview of some major unresolved problems in physics: 1. Unification of General Relativity and Quantum Mechanics The Problem : General relativity explains gravity and large-scale phenomena, while quantum mechanics governs the subatomic world. These two theories are fundamentally incompatible, and a unified framework—often called quantum gravity —remains elusive. Proposals : String theory, loop quantum gravity, and other approaches are being explored but lack experimental verification. 2. The Nature of Dark Matter The Problem : Observations of galaxies and large-scale structures suggest that most of the universe's mass is invisible and does not emit or interact with electromagnetic radiation—termed dark matter . Current Status : I...
