There is a widely extended viewpoint about physical possibility, what we will call Standard Approach, which holds that the physically possible is delimited by the nomological structure of physical theories: to be physically possible is to be in accordance with the physical laws, to be physically impossible is to be prohibited by physical laws and to be physically necessary is to be demanded by the physical laws. However, it is possible to show that this approach is too relaxed and permissive when it comes to collecting and systematizing many of the modal intuitions present in the physical community. In this work we will argue, on the one hand, that the notion of physical possibility is more complex and richer than suggested by the standard approach and, on the other hand, that it is necessary to add some extra elements to the characterization of physical possibility in order to that it is adequate in scientific contexts., Existe un enfoque ampliamente extendido, que denominaremos Enfoque Estándar, que sostiene que lo físicamente posible está delimitado por la estructura nomológica de las teorías físicas. Sin embargo, este enfoque resulta ser demasiado relajado y permisivo para recoger y sistematizar muchas de las intuiciones modales presentes en la comunidad física. En este trabajo argumentaremos que la noción de posibilidad física es más compleja y rica que lo sugerido por el Enfoque Estándar y; además, que es necesario adicionar algunos elementos extras a la caracterización de posibilidad física para que esta resulte adecuada en contextos científicos.
