When objects are accelerating due to gravity, the mass of the object doesn't matter. Galileo demonstrated this by dropping a cannon ball and a bullet from a height, and they hit the ground at the same time. So no, gravity doesn't 'push' or 'pull' either upwards or downwards - is an attractive force between two masses.

Actually, if one considers the gravitational pull of the cannon ball and the bullet, the cannon ball must fall faster, albeit a negligible difference in that experiment.
You make people miserable and there's nothing they can do about it, just like god.
