Physics says no object moves faster than C. Physics allows for space itself, as the substrate for objects, to expand faster than C. My question is how much faster? 2 or 3 times C?
Chronos, what limit would you guesstimate based on current observations?There is no effective limit on the pace of expansion. It appears to have been very rapid in the early universe. Bear in mind, however, this assumes the redshift-distance relationship is valid [which is a fairly safe assumption].
