I hold that space cannot be curved, for the simple reason that it can have no properties. These properties we can only speak of when dealing with matter filling the space. To say that in the presence of large bodies space becomes curved is equivalent to stating that something can act upon nothing. I, for one, refuse to subscribe to such a view.
