This research aims to analyze scientific theories according to the postulates of Popper and Kuhn on scientific research. The methodology used is a documentary-type bibliographic design. As a conclusion, the theory formulation process in the development of science, conditioned to its contrast, refutation and constant new conjecture in search of greater certainty in scientific knowledge according to Popper's position, which could be conditioned not only to Kuhn's position in scientific revolutions and its terminological incommensurability, conditioned to the development of nature and society. That is why, within the development of science subject to conjecture and refutation, trial - error and the process of falsification and contrast, the discussion of incommensurability remains open, not only in the transmission of language, but also the conception of language. Inevitable change both of time-space-phenomenon-researcher; as within scientific knowledge.
