The Top 6 Great Unsolvable Mysteries
in Star Trek

6 How do doors on starships know when someone's going to go through them? Sure, even today we have sensors that open doors when we approach them. But on the Enterprise and Voyager people are always standing beside doors, passing them, even approaching them and then pausing to talk to someone—and the doors never open by mistake. It's only when someone decides to actually leave that the doors hiss open. How do they know that?

5 Okay, I understand the Universal Translator turns every alien's speech
into English that our Federation heroes can "hear". I can even make allowances for the device to work on the very first words that a previously unknown species speaks to our Enterprise and Voyager crews. But how in the world does the Universal Translator make the aliens' lips move exactly to match the English words?

4 How come 24th-century technology can create the Enterprise with all its
incredible computers, warp drives, holodeks, replicators, phase cannons, transporters, and so on—but it can't design a uniform that fits Captain Picard? The male officers are always tugging on their shirts whenever they stand up. Shouldn't there be some sort of space-age clothing material that doesn't ride up like a 1970s leisure suit?

3 Why do Borg drones move so slowly?
Here we have a race that has assimilated thousands of species to acquire their knowledge, so these guys have to be the most technologically advanced beings in the universe. Yet whenever they attack our heroes, these high-tech creatures can't seem to figure out how to get their speed up any faster than a senior citizen on a walker. They plod laboriously along like Frankenstein's monster to make sure the good guys always have time to escape.

2 Why do Captain Kirk and company beam down to the planet's
surface just outside the place they have to break into?

And the Number One great unsolvable mystery in Star Trek:

Where are the washrooms on the bridge of the Enterprise?
Funny how no one on the bridge ever has to leave his or her post for natural functions. And, if they had to, I don't see anywhere they could excuse themselves to. When I asked a friend this question, he guessed that when they really have to go they just beam it out—presumably into space. Man, I wouldn't want to be following that spaceship in warp drive.
