In physics, gauge theory helps scientists take all the measurable things they know and align them in order to find commonalities or definitions…In this paper, physicists Mikko Partanen and Jukka Tulkki turn the universe at large into a bunch of overlapping, finite relationships of symmetry…their goal was to find the mathematically smallest model that could still hold up to all the rules required of a theory of unified gravity.
Nothing wrong with it as a method, so long as it makes some predictions we can then test for.
