Interstellar Communication is communication between different solar systems as well as communication over larger distances. There have apparently been many methods that have been attempted, over the centuries, to communicate between worlds at faster-than-light speeds, by several dozen species. Some of the more interesting and complicated methods range from inducing forced tachyon beams to a quantum entangled state, to slipstream radio. However, there have been no successful instant or near instant interstellar communication managed yet. The Systems Commonwealth have been trying for many centuries to attain FTL and instant communication, because without it coordinating fleet movements and simple regular communication have been hampered.
