The following is a list of notable unsolved problems grouped into broad areas of physics. [1] Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.

Quantum Yang–Mills theory is the current grounding for the majority of theoretical applications of thought to the reality and potential realities of elementary particle physics. [19] The theory is a generalization of the Maxwell theory of electromagnetism where the chromo -electromagnetic field itself carries charge.
Many mathematical problems have been stated but not yet solved. These problems come from many areas of mathematics, such as theoretical physics, computer science, algebra, analysis, combinatorics, algebraic, differential, discrete and Euclidean geometries, graph theory, group theory, model theory, number theory, set theory, Ramsey theory, dynamical systems, and partial differential equations.
In particle-physics, widths from experimental fits to the Breit–Wigner energy distribution are used to characterize the lifetime of quasi-stable or decaying states. [41] An informal, heuristic meaning of the principle is the following: [42] A state that only exists for a short time cannot have a definite energy. To have a definite energy, the ...
The answer is broadly yes, although it gets very complicated. In some senses, the top of the large cardinal hierarchy is in sight. Some theorems have been proven, which impose a sort of ceiling on ...

Let’s face it: when it comes to job interview questions, even the easiest can feel pretty tough -- but these 3 were certifiably hard.
