Heavier objects fall faster because they exert a noticeable gravitational force on the Earth
The claim that heavier objects fall faster because they exert a noticeable gravitational force on the Earth is incorrect; according to the equivalence principle and Newtonian mechanics, all objects fall at the same acceleration in a vacuum regardless of their mass.
The claim is empirically false and directly contradicts the equivalence principle in physics, which states that gravitational acceleration is independent of an object's mass. The provided papers discuss Newtonian mechanics, gravitational mass, and inertial mass equivalence, showing that objects fall at the same rate. Since none of the retrieved papers support the claim and several refute the underlying premise, the balance verdict is REFUTED.

Newtonian mechanics establishes that gravitational and inertial mass are equivalent, meaning all objects fall at the same rate regardless of mass.

The equivalence principle shows that gravitational attraction operates independently of varying object mass effects on the Earth.

Gravitational mass is equal to inertial mass, meaning objects fall with the same acceleration regardless of their individual mass.
