| dc.description.abstract | En física, el infinito aparece vinculado al problema de lo continuo de las representaciones matemáticas usadas por las diversas teorías y, por lo tanto, a la posibilidad de la infinita divisibilidad (lo infinitamente pequeño) y de la infinita extensión (lo infinitamente grande) de la geometría del espacio-tiempo y de los conceptos y magnitudes físicas mensurables. El modelo estándar de las partículas considera que las partículas elementales son «infinitamente» pequeñas, donde surgen cálculos con resultados infinitos para determinadas cantidades físicas y, para eliminarlos, se utilizan métodos de renormalización, usados también en la cosmología clásica y en el modelo estándar cosmológico del Big Bang con la finalidad de domesticar los infinitos (agujeros negros y singularidad inicial). La investigación en gravedad cuántica considera que el espacio no sea infinitamente divisible y los modelos de multiversos suponen tiempos y espacios infinitos para el Universo. Siendo nuestras teorías siempre limitadas y perfectibles, parece que no podemos probar, en física, que el Universo sea físicamente infinito. | pt_PT |
| dc.description.abstract | In physics, infinity appears linked to the continuum problem of the mathematical representations used by the various theories and, therefore, to the possibility of infinite divisibility (the infinitely small) and the infinite extension (the infinitely large) of the geometry of space-time and of the measurable physical concepts and magnitudes. The standard model of particle physics considers that elementary particles are «infinitely» small and calculations arise with infinite results for certain physical quantities. To eliminate those infinities, we use methods of renormalization, which are also used in classical cosmology and in the standard model of the Big Bang cosmology in order to tame the infinities (black holes and initial singularity). Research in quantum gravity considers that space is not infinitely divisible and multiverse models assume infinite times and spaces for the Universe. Since our theories are always limited and perfectible, it seems that we cannot prove, in physics, that the Universe is physically infinite. | pt_PT |
