In the Star Trek: Voyager episode "Night" (S05 E01), Voyager suffers a ship-wide total power drain.  How is the holodeck still rendering Tom Paris' program, albeit in darkness? He turns on a program-driven torch and you can see the screen.

I'm watching the first two seasons of Voyager and various episodes have commentary on having energy limitations -- but we constantly see crew using extremely complicated holodeck simulations. Why would they allow use of the holodeck if they need to conserve energy?

In the Voyager episode , we learn that Tuvok was once a junior science officer aboard Sulu's Excelsior, and that he had been present at the moment of death of Lt. Cmdr. Dmitri Valtane during the events of Star Trek VI: The Undiscovered Country.    If we follow the events as they were presented in "Flashback", then Valtane would have died well before the Excelsior arrived at Khitomer to aid Kirk's Enterprise in the film's climactic battle.  However, at the end of The Undiscovered Country, we see Valtane alive and well on the Enterprise viewscreen (he is the leftmost officer, with the goatee):    In-universe, what is the truth regarding Dmitri Valtane?  Did he survive the events of Star Trek VI or did he perish on the bridge of the Excelsior, only to appear as some kind of...Force ghost?

I'm almost done watching the sixth season of Star Trek: The Next Generation, so I'm starting to look at what to watch next. After reading a little bit about Star Trek: Deep Space Nine and Star Trek: Voyager, it's clear to me that Voyager would be fit my current mood.  Would watching Voyager before Deep Space Nine spoil any event of importance?

In the Star Trek The Next Generation episode  Picard and crew are drawn into an alien conspiracy to take over the Federation. This ends with Picard and Riker destroying an alien "mother" beast, but not before it manages to send a signal to an uncharted sector of space. The feeling at the end of the episode is that this will be a threat that the intrepid crew of the Enterprise would be facing again at some point, but this never happens.   Why was the implied threat at the end of this episode never brought up again on the show?

When a ship is under attack, the shields wear down over the course of the attack.  What is the mechanism behind this? Aren't the shields powered using energy? While the ship has energy, shouldn't it be able to indefinitely defend against attacks the shield can absorb?

Assuming a Galaxy class starship were to work on a regular schedule (i.e. exploring, diplomatic missions etc. but NO battle), how long can it last before it has to return to a starbase for servicing?  I appreciate this may be difficult finding a series of episodes from TNG where the Enterprise-D does not battle between going to a Starbase, so, if it is absolutely necessary, battle can be included, but no major damage...

In Star Trek: The Next Generation episode "" (Season 2, Episode 16) Q seems disturbed by the presence of Guinan to the point of raising his hands as if to use his powers on her. Guinan responds by raising her hands as if to cast a "magic" spell of her own.   Is it ever established what powers she or her race may possess?

I spent a good hour today moseying after some azure-winged magpies. We had a nice waltz across a parkland, they rarely letting me get close enough to even contemplate a shot. As such, I spent long stretches (~10min) with my Nikon DSLR on but not in use.  And then I began wondering about power drain in such situations (switched on but untouched), and how different that status actually was from off, and after what period of time it makes sense to go ahead and switch the camera off?

Can you identify every character and spacecraft in ? Please mention the episode(s) if you can.  The poster is for the 30th anniversary of . (First aired on September 28, 1987.)    I got many of them (along with episodes), but there are plenty I don't recognize. A few occur more than once. (e.g. - Jean Luc Picard and Tasha Yar)

So I have learned in class that light can get red-shifted as it travels through space. As I understand it, space itself expands and stretches out the wavelength of the light. This results in the light having a lower frequency which equates to lowering its energy.  My question is, where does the energy of the light go? Energy must go somewhere!   Does the energy the light had before go into the mechanism that's expanding the space? I'm imagining that light is being stretched out when its being red-shifted. So would this mean that the energy is still there and that it is just spread out over more space?

In a Star Trek TNG episode called "Brothers" Data takes over the ship by throwing his voice and pretending to be Captain Picard. The computer is aware of where Picard actually is on the ship due to its internal sensors, so why would it allow someone who it knows to not be Picard access simply by throwing their voice?

Why is it that if I have two torches, each shining rays in perpendicular directions at perpendicular screens, such that the beams cross, then the images on the respective screens are independent of whether the alternate torch is switched on? In other words, why does light seem to pass through itself without interacting?  Apologies if this question is basic, and apologies if there is a similar question somewhere on the site but I haven't managed to find an answer.   Thanks,  A.

So right now I'm up to season 6 in Stargate SG1, and I've noticed the main crew gets zapped with a  A LOT. Shouldn't they be dead by now? I thought the second shot kills and the third causes the body to disappear. Did this change somewhere? Is there a period of time where if you don't get shot it wont kill you?

What prevents ships firing phasers and photon torpedoes through a cloak? I have yet to see a episode where this is brought up. It may have been mentioned in The Undiscovered Country, as I know there is a kingon ship that does it, but I have not seen that movie in years. Is it addressed there or somewhere in one of the series'?

In the TNG episode "", we are treated to the following line of dialogue...three times.       "Captain's Log, Stardate 45652.1. The Enterprise has entered an area of space known as the Typhon Expanse. We are the first Starfleet vessel to chart this unexplored region."    This strongly suggests that no Starfleet ship has ever actually been into this part of space.    Yet the very end of the episode shows that a Starfleet ship WAS in this section of space, Specifically the USS Bozeman, years ago. Proven when it emerged from a temporal loop just in front of the Enterprise.    How do we account for this inconsistency - saying that the Typhon Expanse has never been charted, and yet there clearly being a federation ship already in the Typhon Expanse?

In the tie-in of SG-1 and Atlantis, they had to use a ZPM to power the gate, and use an eighth chevron to travel to the Pegasus Galaxy. It was (so I thought) common knowledge that they could only travel to gates within our own galaxy unless they had met those requirements.   Now, I recently rewatched the movie, in which the probe traveled to the Kaliam Galaxy, or as Catherine put it, "the other side of the known universe." So, why the limitation on the TV show? And why were they able to travel back to that planet in the first episodes?

Can we ever have a black colored (the color of the light and not the body's color) torch that darken (or dis-illuminates) everything? While compared to a normal torch it would function in an opposite manner. If not now, will it be possible to create this in the near future?
