@mrsbeanbag 's comment about the Eastenders/Doctor Who connection, Doctor Who has referenced Star Trek as both a cultural product (Rose Tyler described scanning for alien technology as being "very Spock" in one of the early episodes of the new DW,) and as a real part of the universe (the 15th Doctor says something like "we should visit them sometime" in the most recent season, referring to the Trek crew). In the last season of Strange New Worlds, Pelia (Carol Kane) starts to tell a story about a "time-traveling Doctor". So Star Trek and Doctor Who can perhaps be said to exist in the same (meta-?) universe, and Star Trek is also a TV show in Doctor Who, so by the transitive property, the TV show Star Trek exists in the Star Trek universe.
