I apologize if this has been asked before, but I have never seen a satisfactory or straightforward answer.
When we say the universe is expanding, do we mean it is "growing" or "stretching"?
In other words, if you considered a sheet of graph paper expanding, are we adding more squares or stretching the distance between squares?
