Summary
| Description |
English: This image is a log-plot, showing the scale factor of the universe (normalised so it is equal to one today) against physical length. The two curves are the Hubble radius (solid line) of the universe from cosmic inflation, through radiation domination to matter domination to today, and the physical wavelength of a fiducial perturbation mode (dashed line). The perturbation mode goes with the scale factor and so is a 45 degree line on this plot. The plot illustrates how the constant Hubble radius during cosmic inflation allows perturbation modes to come inside the horizon in the early universe. If the radiation domination line were continued indefinitely into the past, so there was no cosmic inflation, the mode would never reenter the horizon and one would anticipate chaotic initial conditions for the universe.
All the vertices etc should be correctly located, within an order of magnitude.
Español: Esta imagen es un dibujo logarítmico, mostrando el factor de escala del Universo (normalizado a uno en el día de hoy) contra la longitud física. Las dos curvas son el radio de Hubble (línea contínua) del Universo desde la inflación cósmica, desde la dominación de la radiación hasta la actual dominación de la materia y la longitud de onda de un nodo de perturbación preferido (línea de puntos). El modo de perturbación es proporcional al factor de escala y es una línea de 45º en este dibujo. El dibujo ilustra cómo la constante del radio de Hubble durante la inflación cósmica permite a modos de perturbación entrar en el horizonte del Universo primigenio. Si la línea de dominación de radiación se continuara indefinidamente hacia al pasado, no habría inflación cósmica, el modi nunca reetraría en el horizonte y se anticiparían las condiciones caóticas iniciales para el Universo.
Todos los vértices deberían estar correctamente localizados, en un orden de magnitud. |
