In an expanding universe, a truly stationary bowling ball cannot exist due to the principle that there is no absolute state of rest, as stated by Einstein. All motion is relative, meaning that what is considered stationary depends on the chosen reference frame, such as pulsars or cosmic microwave background radiation. While one can define themselves as stationary relative to certain objects, this is not an absolute measure. Ultimately, the discussion highlights that in practical terms, a bowling ball left on a rack would remain largely unchanged. The concept of motion is inherently relative, making the idea of a stationary object complex.
