This expansion of space was very dramatic: the universe got bigger by a factor of more than 1025 in less than 10−30 seconds. After inflation ended, the universe kept expanding, first at a much slower rate and then more recently at a faster rate due to dark energy. Now the observable universe has a bit of a chance to catch up because it’s still expanding at the speed of light. But how much of the universe is still way beyond the observable universe for us to see? We have no idea, but that’s the topic for the next chapter.
