To be totally fair, FTL implies time travel, and even sub-light (but hefty fractions of light) lead to staggering time dilation effects. None of this is ever touched in most sci-fi and certainly not Star Trek. Everyone is sipping around at high multiples of lightspeed, yet no one ever remarks that they constantly arrive before they leave. They use impulse drives to go at high fractions of c, yet they never return to an Earth many thousands of years in their subjective future.
It’s a great series, but it’s not hard sci-fi, just a great storytelling mechanic.
