No, according to "that thinking" it works the opposite way but that is another issue.

So distances increased (thus more meters were added) and seconds kept ticking away at the same speed (thus more seconds passed). If a distance was once only 1 meter and is now 2 meters, you have more meters, not expanding meters.

If I understand correctly, you are saying the universe does not expand by stretching like a balloon. It expands like a melon by adding more space-time "cells". Is that the general idea?
