I know that the universe is 13 billion years old and the fastest anything could be is the speed of light so if the universe is expanding as fast as it could be wouldn’t the universe be 13 billion light years big? But I’ve searched and it’s 93 billion light years big, so is the universe expanding faster than the speed of light?

Imagine an ant on an elastic band.
The ant can walk at a constant speed (like the speed of light).
You are holding the elastic band and can pull the elastic band and stretch it (the fabric of space) faster than the ant can walk.
The ant will traverse the elastic band, but more slowly (just like light), because there is ‘more’ to traverse, but it’s actually just space being stretched out, not actually more stuff to traverse.
