Re: "SEP-powered spacecraft"
The SEP drive is a wonderful new method of crossing interstellar distances in a few seconds; without all the coronary health implications of sitting around in restaurants, dangerous mucking about with improbability factors, or tedious mucking around in hyperspace.
It simply makes the problem of how you get from A to B very fast, Somebody Else's. Arcturan Megafreighters now use this drive as standard, and can cross the galaxy in seconds with full axial-tilt shifting payloads. The Galactic Navy is also investing heavily in the technology.
Recent research has suggested that the exhaust from such massive SEP field generators manifests exclusively amongst organic lifeforms living in Plural sectors. Sometimes, clues as to their origin can be tracked by observant phenomenologists. Concern has arisen about the possibly disastrous consequences of the explosive growth of this Problem Displacement technology. The group SIYSYM* has cited the recent test runs of the Galactic Navy's new battlecruisers, Trump, Cruz, and Farage, as being potentially catastrophic for primitive lifeforms.
