Everybody knows that sound cant travel through space, but is really valid? Here is my scenerio:
Given the size of a football field's length cubed, there are two objects at two opposing sides. the walls of the vacuum are nonexistent, so the only matter that exists are the two objects. Now if the Object A were to create a noise that were to be loud enough to be vibrate Object B on Earth, would there still be an affect in this theoretical vacuum?
Given that sound energy moves from one molecule to another, would this same energy from Object A travel to Object B to some affect event though the distance between the two in a vacuum is much greater than the distance between to molecules?

From your scenario, you state that the only matter that exists are object A and object B, so no, sound cannot propagate. It requires matter.
Theoretically, gravity wave propagation may occur, so object B may be vibrated by object A, but this is not propagation of sound.
