Random question I like to ponder on the subject of the bowling ball and the feather: if the bowling ball was an object the size of the moon (where its mass is extremely large) and the feather was still a feather, would they still move at the same speed or would there come a point where they no longer do so? In other words, if two objects are released relative to a first object, does the entire range of "infinite" masses all have the same rate of acceleration? Or are the feather and the bowling ball--relative to the Earth--so close to one another in mass, again relative to the Earth's mass, that they appear to function the same?

Also, we live in a unique time in history where we have so many scientific experiments with observations that we do not necessarily need to test hypotheses with new experiments but rather we can essentially go through old experiments with a new interpretation to see if the interpretations align with the already-made observations. That said, such a task inevitably leads to new experiments envisioned to test specific things that have not been tested due to a lack of consideration of certain things as "important" to the experiment.
