star trek - How many people can be in the same holodeck program at the same time?


In Star Trek we frequently see the amazing holodeck function with more than one person in it at a time. In some cases this makes sense, if the people are in only one or two groups, for example. But in some scenarios it seems conceivable that there might be large numbers of people in the same program with everyone off doing their own thing, such as in the Scottish town or beach resort programs in Voyager, or Vic's club in Deep Space Nine. In such situations is there a point at which the computer will not be able to adequately adjust the illusion to keep each group of people separate and isolated?


Obviously the size of the room would impact this (such as Quark's holosuites vs Enterprise-D's holodecks), but has this ever been covered in canon?



Answer



I know this is long, I'm covering all angles. There's almost nothing on the limits of a holodeck, so I want my reasoning to be clear.



I dove into my "solve it all" source for Star Trek: The Next Generation for this and found ... almost nothing, but a few clues. After reading up on holodecks in the Star Trek: The Next Generation Writers' Technical Manual_ (Fourth Season Edition), I found almost nothing about holodeck capacity. There are different sized holodecks, which we never see. (As best I can remember, in all the versions of Star Trek that use a holodeck, we only see one set for each series.) There are personal sized holodecks, but also larger ones (which we've seen more of).


There are references in the WTM (Writers' Technical Manual) to "complete sensory environments," and "If you were getting close to the real walls, you might hear a soft but recognizable beep to get you back to the main illusion." There's also a reference stating, "The exact texture of sand, grass, concrete, rock, or steel is duplicated..." So the focus is on providing as seamless and complete an illusion as possible.


There is no reference at all to any difficulty in creating holograms. (Actually, they go into detail about how cheap OHDs, Omnidirectional Holo Diodes, are to make and to use.) They also don't go into computing time and memory being an issue. That is not mentioned at all, but it could become an issue. However, to use the Scottish town as an example, almost everything in the town would have to be tracked throughout the use of the program, so memory wouldn't be an issue. (For instance, if you throw a ball and it goes behind a building, even if you can't see it, the computer needs to keep track of it for realism and consistency.) Also, if computing time and memory were issues, Janeway would have been more reluctant to allow the crew to maintain an expansive program like the Scottish town.


There is, in the WTM, absolutely no reference to the limits of what a holodeck can do, but repeated emphasis on just how much it can do. However, I can find one limit that would create an issue: Space. The holodeck could create an environment around each individual in the town. Seven of Nine could be in a pub and Harry Kim could be in the field with a young lass. In illusion, they might be several hundred yards apart, but in reality, they might be within 10 feet of each other, but with holograms projected between them to make them both feel like they are in totally different environments within the same program.


Using holograms like this, which would include blocking one person's view of another and replacing it with an image of that person growing smaller as they walk off into the distance, a holodeck could surround each person with an individualized environment, as long as it had enough space to separate them from someone else nearby and to make sure they couldn't reach or move beyond the range of their environment and into another person's.


This would mean that each person would need roughly a space a meter in any direction for the holodeck to maintain the illusion for them. That would mean the limit for the number of people in a holodeck would be determined by how many people could fit in the room with a space of at least 2 meters (one meter for each person) between them.


That would be more of a limit than computing power or OHD capability.


(And it gets more complex, since you could link holodecks, so three or four people could go into the Scottish town from the biggest holodeck and someone else could enter at the same time in a small personal holodeck - and the computer could keep the continuity between the two matched so if the person in the personal holodeck went into the same pub as the people in the other holodeck, the OHDs could project images of all of them so they'd "see" each other when they meet in the pub.)

futurama - How much time is lost in 'Time Keeps on Slippin''

In time Keeps on Slippin' , Farnsworth creates a basketball team which he matures by abusing Chronitons. This leads to time skipping forward by random, but ever increasing amounts. How much time was skipped in this way? Answer Unfortunately, I don't think a good estimate can be made for this, for two reasons: Many of the time skips move forward by an indeterminate amount of time. At one point, the Professor mentions localized regions of space skipping forward much more than others. We then see two young boys on the street below complaining about having to pay social security, only to suddenly become senior citizens and start complaining about wanting their money. Thus, each individual could have experienced a different amount of time skippage.

harry potter - How could Expelliarmus beat Avada Kedavra?

I want to be very careful about how I ask this question – I am not asking How did Voldemort die? [CLOSED] Below the text is the relevant passages from Harry Potter and the Deathly Hallows if anyone wants to review them (I'm sorry for the amount of text). How did Expelliarmus beat Avada Kedavra and kill Voldemort? I feel the reason Harry's Expelliarmus overpowered Voldemort's Avada Kedavra curse has to do with who was master of the Elder Wand and how the Elder Wand works. I've always had trouble understanding fully how the Elder Wand works, though. How much did the fact that Voldemort never truly won or mastered the Elder Wand factor into how Expelliarmus reacted to Avada Kedavra and caused Avada Kedavra to rebound and kill Voldemort? An answer based in book canon would be especially welcome, but any canon source really is fine. Harry heard the high voice shriek as he, too, yelled his best hope to the heavens, pointing Draco’s wand: ‘ Avada Kedavra !’ ‘ Expelliarmus !...

Is there good canon evidence for the "Nightmare Matrix"?

On the Matrix wiki, there's an article about the Nightmare Matrix which says: The Nightmare Matrix was the second prototype Matrix, designed by The Architect after the massive failure of the Paradise Matrix in the hope that human minds would more readily accept an imperfect world with suffering. Unlike the first version, this Matrix instituted a basic cause-and-effect programming and forcibly made those connected to it accept the program. Vamp Prime, a possible remnant of the Nightmare Matrix. It also featured programs that resembled mythical evil creatures in various human mythologies such as vampires, werewolves, zombies, aliens, etc. It also failed, but many of the programs who were designed for it survived deletion in exile. The Merovingian and his wife, Persephone may have had their roots in this version of the Matrix. Upon its failure, the Merovingian started a smuggling ring of programs and information to provide a haven for exiles that would last for 6 cycles in the final ...

story identification - Anime with a boy hiring a creature from a stone, meets a man named Dante and starts a journey to collect crystals

I am from India, this anime or animated series (I can't remember this was made by the Japan or other countries) was aired between 2009 and 2012 probably in Jetix/Disney XD (but I'm not sure). This anime starts with a boy (the main character, I forgot his name) who find a stone (or crystal like thing) in his dad's property, his dad was missing that time. Some day he accidentally hire a creature/monster from that stone. Other day some creature attack him and he was saved by his creature and the story begins. In his journey to solve the mystery he meets a middle aged man 'Dante' (probably that was the name; this is the only character name I can remember). He had also some stone. After that they meet with one girl and a women (one of the girls is same age with the main boy character and probably will become his partner as the story goes on). Another women probably Dante's partner. Four of them started their journey to collect all the stone/crystal. They are collecti...
