Antonio Lao said:Does anyone know whether the expansion of the universe ever exceeded the speed of light taking the early accelerated phase into consideration?
If not then the early photons must have bounded back and forth within the boundary of the early universe and a few or maybe many of all photons we are seeing now are rebounded photons.
According to Alan Guth, the first to clearly develop a model of the inflationary universe at an earlly stage around ten to the minus 34 seconds or so, the size of the universe doubled many billions of tiime. However, if we considered the universe a crystal lattice and you were at one of the host sites, you would see everybody moving away from you at "many orders of magnitude" greater than the speed of light. However, no one would feel the slightest acceleration as it wasn't mass that was expanding, it was the space that was growing so rapidly. In this inflationary time gravity was effectively "repulsive". This kind of expansion was necessary to overcome the speed of light limitation for the calibrating of pariticles separted by large distances in order to maintain a perfect state of equilibrium while the universe achieved a minimum safe size to ensure continued expasnison. If the universe weren't perfectly uniform for some critical time the expansion would have been a dud and the universe would collapsed back on itself.
As the inflationary expansion did not involve movment of matter through space all mass was effectively immobile and mainitained a oerfect state of equiilibrium and order, and not inviolation of any relativistic constraints. This problem proved somewhat embarrassing later when the COBE sattellites showed cosmic back ground so perfectly smooth that the formation of stellar bodies would have been impossible, according to BB theory. Mass could not have congealed into the massive obsjects and in the formative patterns we see. A reassesment of "interferences in the data '" of "near Earth influence", was subtracted out and sufficient disturbances were observed in the background microwave remnant. Suffiicient perturbations were found buried such that we have stars and galaxies as we see.
