Wait, what, so atoms, neutrons, quarks etc. are all growing and moving apart at the same rate as the Universe?

- simonh 5y agoThe expansion at a local level is too slow and is overwhelmed by the local forces holding these structures together. Only at the cosmic scale, where the gravitational forces between galaxies and clusters or super-clusters of galaxies are very tenuous, the expansion takes over.
- herrkanin 5y agoThe forces that keep atoms, neutrons, quarks etc bound to each other is stronger than the force caused by space expanding. Therefore, space expanding is mostly observed when measuring distance between galaxies.
