That's a valid point. Supposedly the "Big Bang" was an almost instantaneous expansion but instantaneous relative to what? It's kind of opposite the effect at the event horizon of a black hole where, from the outside perspective (earth), something near the event horizon is slowing down but for the particles perspective, everything appears normal.
