First, is one light wave (or perhaps half wave) possible that stretches across the universe, such that each end of the wave (or half wave) is on opposite sides of the event horizon of the universe, which is the distance light has traveled since the beginning of the universe.
Second, is this wave length (or half wave length) the longest possible wave length--excluding the fact that the universe is expanding and the wave length can lengthen.
