  2. Theoretical physics - Wikipedia

    en.wikipedia.org/wiki/Theoretical_physics

    The proposed theories of physics are usually relatively new theories which deal with the study of physics which include scientific approaches, means for determining the validity of models and new types of reasoning used to arrive at the theory. However, some proposed theories include theories that have been around for decades and have eluded ...

  3. Theory of everything - Wikipedia

    en.wikipedia.org/wiki/Theory_of_everything

    A theory of everything (TOE), final theory, ultimate theory, unified field theory, or master theory is a singular, all-encompassing, coherent theoretical framework of physics that fully explains and links together all aspects of the universe. [1]: 6 Finding a theory of everything is one of the major unsolved problems in physics. [2] [3]

  4. Category:Theoretical physics - Wikipedia

    en.wikipedia.org/wiki/Category:Theoretical_physics

    Theoretical physics is physics that employs mathematical models and abstractions rather than experimental processes. Theoretical physics attempts to understand the natural world by making a model of reality, used for rationalizing, explaining, and predicting physical phenomena in what are called "physical theories." There are three types of ...

  5. Branches of physics - Wikipedia

    en.wikipedia.org/wiki/Branches_of_physics

    Physics is a scientific discipline that seeks to construct and experimentally test theories of the physical universe. These theories vary in their scope and can be organized into several distinct branches, which are outlined in this article.

  6. List of unsolved problems in physics - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    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. The others are experimental, meaning that there is a difficulty in creating an experiment to test a proposed theory or investigate a phenomenon in greater detail.

  7. Unified field theory - Wikipedia

    en.wikipedia.org/wiki/Unified_field_theory

    According to modern discoveries in physics, forces are not transmitted directly between interacting objects but instead are described and interpreted by intermediary entities called fields. [1] However, a duality of the fields is combined into a single physical field. [2] For over a century, unified field theory has remained an open line of ...

  8. Grand Unified Theory - Wikipedia

    en.wikipedia.org/wiki/Grand_Unified_Theory

    These theories predict that for each electroweak Higgs doublet, there is a corresponding colored Higgs triplet field with a very small mass (many orders of magnitude smaller than the GUT scale here). In theory, unifying quarks with leptons, the Higgs doublet would also be unified with a Higgs triplet. Such triplets have not been observed.
