Question

does space-time expansion affect on fundamental particle or point particle?

Answer 1

Answer to original version of this question, which was:

Can we find out about expansion if everything from atoms to universe...expanded?

If atoms were expanding, the properties of matter would be changing and we would notice. Our bodies would rip apart before atoms would significantly expand.

According to Phantom Energy and Cosmic Doomsday , first the Milky Way galaxy would be destroyed, then the solar system would become unbound, next the Earth would explode and only at a much greater level of expansion atoms would expand.
