A logical and acceptable in-universe explanation of why Harry, Hermione and the Order of the Phoenix don’t use Muggle technology, specifically guns and knives, is that they never attempt to kill, but only to incapacitate or capture Death Eaters. Refer to that restaurant scene in Deathly Hallows. The lowest common denominator of the HP series has been love. ...

I've read The Machine Stops a few times, and I don't think it's quite similar enough to the internet. There, the humans live within a giant machine. But the internet is a network of machines. For something a little closer, I think, I'd go with Murray Leinster's "A Logic Named Joe." from March 1946. You can find it for free from the Baen Free Library. In A ...

There's no on-screen canon explanation given. However, the Star Trek: The Next Generation - Technical Manual states The main viewer display matrix includes omni-holographic display elements and is thus capable of displaying three-dimensional information.

The video clip shows what is referred to as "war-dialing" a term which was in fact coined from the name of this movie. The "hacking" implied here is that the phone number for the victim computer's modem is not publicly known, but by scanning a range of numbers, dialing one by one, a "secret" modem can still be located. Guessing username and password is the ...

I think you’re misinterpreting the Prime Directive. (It’s not actually written down in any official Star Trek work, so any discussion of it is necessarily going to be a bit vague.) The Prime Directive is, in part, intended to prevent Starfleet from visiting less-advanced civilisations and dicking around with their development, whether for fun, profit, or ...

Of course for all things Star Trek Memory Alpha has the answers. Regarding transporter pads: The transporters installed on Earth's NX-class starships featured one large circular pad that took up the entire platform. It was large enough to transport two to three people, provided they stood close together. By the 23rd century, Federation transporter ...

In the Star Trek: Voyager episode “Year of Hell,” there is a scene where the viewscreen is offline due to heavy damage to the ship. What's interesting in this is that it is not simply black, like a monitor nowadays when offline, but it has a structure that looks exactly like the wall of Voyager's holodeck. So I guess it achieves the fancy 3D effect by ...

I'm not aware of canon answer, but an in-universe common sense answer makes perfect sense. Have you EVER tried to network modem-equipped laptop with a Ethernet-equipped server with an Apple product that has some proprietary network connection (Appletalk protocol)? How about a droid with Token Ring and another one with X.25? How about something more modern ...

Magic, in the Lord of the Rings, is actually quite limited in comparison to similar tales. Most magic is of a passive nature, like the protections of Lothlorien from evil, the doors to the Mines of Moria or the glowing of Elven weapons when orcs were around. As such, it wasn't part of most non-Elven people's day to day lives, and Hobbits and Men could go ...

While looking up some information about this I stumbled across this... It's not entirely canon but it gives a good theory about why it is that wizards and witches might not use modern items. From "When Magic Meets Muggle Technology" at Harry Potter Lexicon Magic in the Harry Potter world is a power that wizards and witches are able to harness and ...

According to a lot of the Star Wars Extended Universe info, they actually arc back after a certain distance; it's just not terribly visible in the movies; think of them arcing back in a beam right next to the one emanating for the emitter. (It may help to think of a magnetic field (like the traditional 'Magnetic Bottle') being generated to point the out-...

Firstly, Nostromo was constructed in 2101, only 12 years after Prometheus. Secondly, not all types of vehicles have the same level of UI polish. Generally, military and industrial vehicles/systems tend to look a bit dated compared to the latest consumer vehicles/products. Here's a cutting edge F-35 cockpit: Here's the Eurofighter, which is about ten years ...

The real reason Slugs > Blasters against Jedi is really more straightforward than you'd think. Blaster bolts can be reflected, slugs will be burned up by the blade. This removes a significant counterattack from the Jedi. Slug-throwing weapons have a higher rate of fire. Jedi might seem impervious in the movies, but anyone can make a mistake. More ...

I think the answer is a lot simpler than the philosophical answers I've seen so far. So I am going to take a shot at a logical answer. For a moment, as you read this, imagine Spock is giving you this answer :-) Once a civilization has attained warp speed travel, they can hardly be prevented from initiating first contact of their own accord. It would ...

On the One Hand: Often self-destruct is not a feature of the ship, but is more of an option inherent in the power / propulsion system. If you turn off all the safeties and let the warp core / nuclear reactor / unobtainium go out of control, it will overload and blow up the ship. You could, in theory, allow a reactor meltdown to happen on a nuclear powered ...

Well, according to Wookiepedia's entry on the Death Star: The Death Star's superlaser derived power directly from the hypermatter reactor. Its faceted amplification crystal combined the destructive power of eight separate tributary beams into one single blast with the intensity of a stellar core. After firing a blast, though, the Imperial engineers had to ...

One of the earliest examples of something similar, and one often hailed as the earliest mention of many modern concepts, is E. M. Forster's The Machine Stops from 1909. The story envisions a post-apocalyptic world where the surface has been made uninhabitable and people reside in tiny cells inside a huge underground complex overseen by The Machine. The ...

The Tollan were wiped out when Anubis, half-ascended and still bearing incredible knowledge of Ancient technology, arrived with ships that had been upgraded with said Ancient technology, rendering them impervious to the Tollans' ion cannons -- the only defense they had against attacks from orbit. After SG-1 destroyed the phasing bombs they were building for ...

I don't think Tony's work was based on Hydra's any more than the Pentium 4 was based on the vacuum tube computers of the 40s. It's always seemed to me that, in the Marvel universe (especially the Cinematic Universe) powered suit technology isn't treated as anything truly innovative, just something that's not effective. The miniature arc reactor, which Tony ...

On careful examination, the Droideka's gun turrets appear to extend outside of the defensive shield. When they fire, they either do so with the muzzle precisely aligned with the front of the shield or simply with the gun sticking right outside. The recoil obviously brings the blaster arm back inside the shield, presumably this also prevents their opponents ...

According to several sources, including the TNG novel "Balance of Power", latinum is described as being so dense and complex that the replicators are unable to restructure matter into a form that duplicates it. In its natural state, latinum is a liquid which is mined from certain types of nebulae. It is pressed into gold in order to make it more usable as ...

Yes, provided there is an oxidizer. A spaceship with liquid hydrogen and liquid oxygen will blow up quite well in the vacuum of space. Chemical explosives will also explode in space since they function by breaking weakly bonded chemical components; no oxygen is necessary. Nuclear explosions can of course occur in space, too. However, in space, there is no ...

First, it is explicitly stated that electronics don't work in areas with a lot of magic around. It helps explain why the wizards don't have the best of both worlds. Most of the gadgets Muggles would use in combat, from radios to nightvision, and even some weapons, would be rendered useless simply by there being so much magic around. Second, it's implied in ...

(I think I've read all the answers and most of the comments, yet... Sorry if I'm duplicating anyone.) Let's consider the question and its implications historically. Guns have been around for ages. However, magic and wizards have been around for way longer (remember, Hogwarts was founded around the 9-10th century.) It is quite logical and safe to assume ...

The flux capacitor is powered by Mr. Fusion. You can see it on the back of the DeLorean in the following photograph. We can assume Doc put some appropriate items into it (such as food and other materials like at the end of Back to the Future or beginning of Back to the Future Part II) and they then just need to get the DeLorean up to 88MPH which is done ...

I'm not sure if it's close enough to qualify, but Jules Verne's "Paris in the 20th Century" (1863) describes electrically-powered mechanical calculators which can send messages to each other. Mark Twain's short story "From the 'London Times' of 1904" (1898) describes a worldwide network of "telelectroscopes" by which "the daily doings of the globe made ...

They are on a space station that can destroy terrestrial planets like Alderaan. We don't know how it deals with Jovian planets---and Yavin must be Jovian to have a terrestrial-size moon. From a simple physics point of view, the gravitational binding energy of a Jovian is orders of magnitude larger than that of a terrestrial planet which allows for a number ...
