Where does the extra space come from as the universe expands? and if it’s just stretching, does that mean it somehow is getting thinned out?

Follow up – is Gravity able to counteract the ‘stretching’ by keeping things together? That seems counter-intuitive if the amount of distance is increasing – wouldn’t the distance between atoms increase, even if they were held together by gravity, in the same way that the distance between two stars would increase, despite whatever minute amount of gravity they affect one another with?
It feels like if gravity is able to counteract this process, then this force is relatively weak.
