Gate Mechanics

A gate is type of small wormhole that connects two distant points in space. Gates result from a quirk of hyperdimensional geometry where the presence of a gravity well in an area affects certain particles in quantum entanglement, causing the higher-dimensional space between them to fold in on itself (for the details of why this happens, wait 2500 years for Markus Tannhauser to publish his book on the subject). Like any waveform, spacetime can be added and subtracted from itself, and in certain cases the foldspace phenomenon ends up being subtracted enough to bring the two consanguineous entangled particles close enough to each other in higher-dimensional space to cause a noticeable spatial discontinuity at either end.
