Re:
Vacuum issues.
Of course a vacuum can exist without edges. When tesla states " albeit: Inside an apparently infinite area (Volume) because of expansion." he shows that he fails to understand that the Universe does not have edges merely for dimensional reasons. Until he grasps that he'll not be able to understand why his question is trivial.
Tesla, hold a sphere up to the Sun and observe its shadow. Notice the shadow has edges even though the sphere has not. This is your error.
