Expanding means that the objects (stars, galaxies and stuff) are moving further apart, not that any of them is growing on it’s own. Think of a raisin muffin. Before baking all raisins are relatively close but at the end, they moved further away. It’s not that “the other” raisins grow, they are just further away. What grow is the space between them (or dough to stay in the metaphor)
Big, huge, unfathomably large structures in the Universe, such as galaxies, are measurably expanding away from each other.
The atoms that comprise your body are not measurably shrinking.
We are not shrinking. Astounding large things that are very far away from us are generally getting further away from us, and other astoundingly large things.
To further the raisin bread analogy:
The raisins are not shrinking, the dough is expanding, making the distance between the raisins increase.

Are they moving apart or are we moving further away by becoming smaller?
