In the TNG episode where Riker keeps getting deja vu from constant mental simulations (effectively him living a Groundhog Day), what kind of nanotech that isn't Borg influence a person's mind like that? Also, does the episode have a Wiki article? I want to read it to see what they say it was to understand it more without asking too much.

Why can holodeck safety protocols just be disengaged? Doesn't that defeat the purpose of having them?

I was just watching "Mirrors" and it got me thinking about the Class 8 probe from "The Emissary". I do not know if there are any other types of warp pods in the prime universe that have been seen, but they both look about the same size. I know the probe was only a 1 person transport but the arrival of the ISS Enterprise before or during the Dominion war would mean that the Terrans had created this warp pod at some point. Is the warp pod something that came from the class 8 probe or is completely different due to them both being from alternate universes?

How long can a ship travel for without refueling its warp drive (with deuterium/antideuterium/dilithium)?

If the EMH is programmed with so much knowledge, and is superior to regular doctors, should it be used on a regular basis as the chief medical officer of ships and space stations, instead of regular doctors, and why?

The EMH:

• Included the entire starfleet medical database.

• Contained over five million medical protocols - ranging from possible treatments to surgical procedures.

• Has the collective medical knowledge of over three thousand cultures (including every federation world).

• Possessed information from two thousand medical reference sources (including gray's anatomy and comparative alien physiology).

• Has the experience of 47 individual medical officers.

• Is also supplemented with contingency programs and adaptive programs to learn while serving as a supplement of a normal medical staff in cases of emergency.

• Contained fifty million gigaquads of computer memory, which was "considerably more than most highly developed humanoid brains.".

If you could create any holodeck program, what holodeck program would you create, and why?
