Does the expanding universe model mean that our Milky Way galaxy is at the center of the universe?

Answer 1

Short answer: no

Every spatial point in the universe is expanding simultaneously, according to the expanding universe model, which also explains universal inflation. Nothing is at the center of the universe.

This is often explained by comparing it to the idea of being on the surface of a balloon that is blowing up, with each point on the surface getting farther away from every other point, but with no single point being the center.

It is not implied by the expanding universe model that the Milky Way is at the center of the universe. The idea behind expansion is that galaxies are uniformly moving away from one another; there is no singular center to this expansion.
