I believe that we have also debated:
If you shoot a 50 BMG and .22 short on perfectly horizontal ground (not taking into account the curvature of the earth) from the same height, which bullet will hit the ground first?
If fired at exactly the same time and all else equal, they will BOTH hit the ground at the same time. One will just be much farther away when it hits the ground. Gravity is what pulls the bullets down and gravity acts on both the same.
