Makes sense.
How could the universe possibly expand? What exactly would it expand into?
Beyond the universe is nothingness. Nothingness is, well, nothingness. No mass. No time. No "space", which is made up of length, width, and height. Nothing. So how could anything expand into that? There is literally "nothing" to expand into. No structure to hold what is expanding.
