The wiggle room within Star Trek is that the Tkon Empire was supposedly wiped out by a supernova despite being a highly advanced civilization, and in “Second Sight” the DS9 crew boosts the top speed of a ship to warp 9.5, which suggests that a supernova can have superliminal consequences.

But there’s nothing to suggest the Tkon supernova was a natural phenomenon, and the hijinks they were up to in “Second Sight” certainly wasn’t.
