According to the inflation theory there is a horizon where space is receeding so fast from an observer such that light will never reach the observer. First, I thought that matter could go equal to or faster than light. This being so, if A is receeding at 0.999...c and B is receeding at the same, wouldn't the additive speed still be less than light speed, and light would reach the observer? What am I missing here? Is it that the light is so red-shifted that there is no discernable information?
