Rapid expansion looks the same as infinitely large and finitely old, in this case. Our universe, as it turns out, also seems to be expanding in addition to being finitely old. If it were not, the sky would slowly be getting brighter, but it will in fact only get darker from here on out. The space beyond the edge of the observable universe will be forever out of reach, even to light.
