I’ve read many answers on this site about space expansion and I will write from what I understand so please correct me if I’m wrong.
- The space between galaxies expands but the galaxies themselves are stationary and have no real motion due to the expansion.
- After inflation stopped, the universe continued to expand because of inertia. (decelerating expansion)
What I’m asking is, why didn’t the universe started to contract immediately after inflation stopped?
How can there still be inertia to drive the expansion after inflation stopped, since its the space itself that expands, not galaxies moving in space?
