Ok. The expansion on human scale is tiny? But not zero? So on a scale that is external to space (measuring from outside the perspective of being IN space) how much bigger r we compared to the past. Or am I totally off on this?

We are the same size because gravity and electromagnetism counteracts the expansion.

Basically the expansion “pushes” two things apart, but if they are close enough, their gravity will just pull them together faster.
