If an object has zero mass

    Is it true that if an object has zero mass, and zero inertia, it would move spontaneously in any direction without an applied force?

    It wouldn't be an "object" would it? It'd be free (n-dimensional?) space I think.

    yes, in a way it is true, but forces by its very definition applies only to inertial objects so it isn't really that the object can move without an applied force, strictly speaking.
