This is not an alternate theory, but more of a physics challenge question that will take ingenuity. I would have posted this in the physics section, but they seem to be afraid of my challenges. Anyone is welcome to participate. To set the stage; if you take a beach ball and try to submerge the ball in the pool, there will be an upward force connected to buoyancy. The question becomes, can we use buoyancy to generate enough velocity to launch a missile, from deep down in the ocean, into space? Before dwelling on the technical limitations, such as friction and materials, this exercise is only to access whether the ideal missile, in frictionless water and air, could gain enough speed to reach space, driven only by the forces of buoyancy.
