The Theory of Differences between Elements explains the reasons for the differences in physical concepts between different elements, such as quantum physics and the Theory of General Relativity, which are explained by an excess of observations. Thus, it is possible to conclude from the observations that the differences are motivated by the reactions between the specific elements, by the composition of the specific elements and by the intensity of the specific physical concept that promote losses and gains of characteristics. Therefore, there is no general similarity between quantum physics and the Theory of General Relativity. The study aims to understand the elements and their physical concepts that make up the Universe.
