An actual stargate creates a wormhole through space. Although this doesn't create a wormhole through space, it does launch a small craft across space at a very high velocity. I recommend keeping the stargate neutral that way it is not attacked. A small amount of thrusters are on board the stargate to move it. Pulsaters are used to propell a small craft to the farthest edges of the universe. NOT my original idea. Idea derived from GeneralVonDoom's "Mass Relay". Here's his prototype video. Can also be used to fire mines toward a long range target. It was built by the scientists at the Wolf-Gaurd Propulsion Lab. Enjoy!
