Actually objects in a vacuum fall at the same speed. Why?
Actually, no they don't. Buoyancy (and drag) is still in play in a partial vacuum. They fall very similar (often too similar for the precision of our instruments to detect) speeds. You may want to re-read my previous answer to this question.
The acceleration profile in falling is most influenced by the media. The reason things fall is due to their weight, and although the weight of the larger object is greater - it has more matter to move!
Furthermore, the fact that it does appear that if a perfect vacuum were possible to exist - that all things would fall at the same speed essentially rules out the idea of a propagating "force"/"pulling" wave being the cause of it. It is not really a mystery why gravity waves are purely imaginary. If they existed they would need to routinely violate many fundamental laws of nature.
Because the weight of the object doesn't matter. Something else is pulling the object towards the earth.
Why do you think this? The weight of the object (and being greater than the media it displaces) is all that is required for things to fall. Scientifically speaking, it is the experimentally verified and verifiable cause of falling. It requires no magical "pulling force" which is utterly unempirical and hopelessly unscientific (which newton well knew and understood when he invoked it to solve an astronomical math problem).
