since objects are also points in space, does this mean that objects expands also with space? if so, then there should be no noticeable/measurable expansion, since the ruler is supposed to go longer too in proportion as it measures the expansion of space. if space expands between two non-moving particles, does it mean that the expansion of space is independent from the natural movement of particles in spacetime? since particles are in constant motion relative to space and time.
