I understand the movie stated Red Matter was of Vulcan origin, but could the reason the Vulcans developed such a technology was to create an artificial singularity similar to what Barclay needed for communication with Voyager via the MIDAS array? I understand the events of the Hobart star collapsing was much after the arrival of Voyager in the Alpha Quadrant, but could the Vulcans not have mothballed the tech because Barclay had already devised a way of using the pulsar to generate the micro wormhole?
