Hi to all. Since this is my first entry on the TrekBBS forum, I hope you won’t mind if I write something wrong or incomprehensible. I'm from Croatia, and I've been a fan of Star Trek and science fiction in general for many years, so I follow Discovery regularly. One of the dilemmas that bothers me with the plot of the third season, which I failed to logically resolve, is the question of the propulsion system used by the Romulan D'deridek class warbirds. That is forced quantum singularity, as an alternative to the classic warp drive. Therefore, it is not clear to me why the Federation, in the absence of dilithium, did not turn to the mentioned technology? Or simply the answer lies in the fact that current Star Trek screenwriters do not know enough about Star Trek mythology? Toughts?
