To my mind, in case of absolute vacuum , the space time will collapse and vanish from this universe,creating a blackhole. The spacetime is thus vanishing on one side and is being created with the expansion of mass/energy. It is difficult to say at this stage whether overall universe is expanding or not as we cant find as how much of the space is vanishing. But effectively it is expanding. The black holes as commonly believed are not caused by the gravitational pull of nearly infinite dense mass, but because of massless space collapsing due to gravitational pull, spacetime being the property of mass energy as in the Mest Toe. Space cant exist on its own as its not an independent entity.
