Light cones and expansion
Referring to light cone as the projection over time that an object/event can be observed in space at increasing distance (probably not the most succinct definition but as I understand it). If the rate of expansion increases based on the volume of empty vacuum being measured, is it still possible that expansion can exceed the speed of light (as postulated in the Big Rip cosmological model)? I am unaware of what the latest in the Big Crunch/Heat Death/Big Rip projections are.
We can see back to the Cosmic Microwave Background, before which there is simply no older light by which to measure. Is it feasible to assume this could be as much the result of expansion faster than *C* distancing us from all light in the universe that may have been present before the Big Bang, as it is to assume there simply was not light before it? And since a light cone (I believe) also defines the limits of an object/event to have any effect on others, would this change anything about our model of the universe?
