If the universe is only 14 billion years old, how can it be 92 billion light years wide?

There was a time when parts of the universe were moving away from other parts of the universe faster than the speed of light. That time is right now. The point is space itself is expanding everywhere at a very rapid rate. It was even more in the very early universe, during a period called super inflation. Then it settled down to something reasonable, but because of Dark Energy, the expansion will become greater over time.

This video explains and clarifies what we mean by the visible universe and the microwave background radiation. However, it takes some effort to understand it.
