¿Qué nos dicen las observaciones cosmológicas sobre el Universo?

Ureña-López, L. Arturo
2007-02-01

Resumen en español Las observaciones cosmológicas actuales comienzan a guiar la especulación teórica alrededor del origen, evolución y composición del universo. Se presenta aquí un pequeño resumen de cómo las observaciones pueden utilizarse para validar y sugerir cambios a los modelos cosmológicos que se han construido hasta ahora. Resumen en inglés Current cosmological observations begin to guide theoretical speculation about the origin, evolution and composition of the universe. This is a small review of how observations can be used to validate and to make changes to the cosmological models that have been built up to now.
