Boy, I hate to be pedantic about this, but in a vacuum the heavier object
_will_ reach the surface of the earth faster than a lighter one if both
are released the same height above the ground.

That depends where they come from. If you pick up the feather (leaving
the stone on the ground), the stone's mass is part of the Earth's mass.
If you then drop the feather and pick up the stone, the feather
becomes part of the Earth's mass for that experiment.

The total mass is the same.

This is true in real experiments too, unless you can "beam" the stone
away while playing with the feather.

End of pedantry.
