Physics is the branch of science that deals with the classical/ transapient laws and workings of the physical universe, from the macro-scale to the quantum, subquantum, and sub-planck levels. While the Orion Arm verse have had major paradigm shifts in regards to the field in correlation to information physics, topological physics, and Z-Theory; some areas of specialization you can learn include classical mechanics, thermodynamics/entropics, classical relativity, quantum mechanics, singularity physics, hyperdimensional physics, unified field theory, superstring, brane theory, gauge theory, the physics of nano-scale objects, particle physics, condensates, to name just a few. Unsurprisingly, given the applications it has in many other fields of science and technology, it plays a critical foundation in nano/mega-scale metric engineering, interstellar travel, and more in all facets of this verse.
