Chewbacca’s bowcaster is firing red projectiles in Episode VII. As far as I can remember from movies, shows and games bowcasters only fire green projectiles.    A Wookiee firing a green projectile from a bowcaster in Star Wars: Episode III (at about 50 minutes)  Why does Chewbacca’s bowcaster fire red projectiles in The Force Awakens? Is there more information about this bowcaster? Have there been others that I did not notice?  A related question:

In “The Force Awakens” Han Solo, Chewbacca and Finn are caught in a battle on the planet Takodana—where Maz Kanata lives, hangs out and does whatever she does—and Chewbacca begins using his bowcaster to pick off Stormtroopers like flies. At one point in the middle of the battle, Han Solo asks to try the bowcaster out and exclaims something along the lines of, “I like this thing!”                                  Okay, okay… Han Solo likes that big, bad powerful bowcaster… But why is he so surprised and delighted by its power and handling apparently only now in this film? Hasn’t Chewbacca had that bowcaster for at least 30 years? And within those 30 years you are telling me Han Solo has never put his hands on that bowcaster before? Or witnessed its power in action? Really? The first time he’s touched it is during the events in this film?  What is the in-universe explanation for this?  I mean I know some couples are shockingly oblivious to the things their partners have, use, do and have done. But this seems a bit of a stretch coming from someone like Han Solo who seems to spend endless days/nights with his Wookiee sidekick getting into all kinds of wacky action/adventure predicaments.

I've been looking into the inner workings of blaster weapons primarily using Wookieepedia. While most of it I understand, I still can't figure out how many rounds a gun would fire before needing the ammunition component replaced/reloaded. Is there any solid answer?  I'm someone who likes to design and draw his own weapons and such, but likes to keep to how the technology of an era is in mind. While Star Wars weapons don't really have magazines (and you don't really see them reloading during battle), other people's work still has magazines and treat ammunition consumption as though it's pretty much the same as our modern era.  I guess that I just find it hard to believe, with the technology of the Star Wars Universe, that characters would need to carry lots of ammunition (hence why clones/storm troopers/battle droids don't visually seem to carry very much).  Example: DC-15A     "The weapon's tibanna gas cartridge carried enough gas for up to 500 shots, depending on the power settings of the weapon, while the charge pack lasted about 50 shots"   Source:   I've read in several places that this can be seen in two different ways.  1. Which ever ran out first, had to be replaced before the weapon could fire again. 2. The weapon contained two different sources of ammunition (so I guess you could switch between the two)

When stormtroopers get into fire fights with the rebels, I noticed that a few are killed after a single shot to the chest. Is their armor not really armor or are the rebels guns just that powerful? In some of the books in Legends, it seems they can take more of a beating but in the original movies they can't seem to take as much. Do some stormtroopers have different grades of armor?

Admiral Ozzel has them on both sides of his uniform (upper chest).  Most Imperial officers seem to have them.  Han, pictured also here, has three such cartridges on his jacket.  I'd like to make such a jacket and use anything that looks like them.  I figure they are most closely related to cartridges for guns.  (which is what I imagine they are in the films).  But does anyone know the real scoop on them?  What is their purpose in the Star Wars universe?  Admiral Ozzel:    And Han Solo:

In Episode III,  explains to Anakin the power of the Dark Side to save people from death. He mentions  - the Sith who discovered this. Sidious then claims he died, which seems odd, given that kind of power.   Then in Episode VII (The Force Awakens) we find a Sith Lord who has appeared from no where. There seems to be two loose ends that fit nicely together.   My question is: Is there evidence to suggest that Supreme Leader Snoke is Darth Plagueis?

Where do we first see/read about a lightsaber in the Star Wars universe (EU and Legends count)?    I mean this from an in-universe chronological perspective, not publication/release order.  It’s a simple question, but I've searched some existing question and answers on here and a few other sites online (yes, including wookieepedia...) but have not found anything useful yet.

The Avada Kedavra curse is recognisable by the flash of green light and the rushing noise emitted from the caster's wand.   -    I thought green was commonly one of the colors used by light side (the good side). Like in Star Wars, where Jedi light sabers are green or blue, but Sith light sabers are mostly red. But in Harry Potter the light emitted after casting the Killing Curse is green and the defensive spell (casted by Harry Potter) is red. Why the colors are switched in Harry Potter?

In the prequel trilogy of Star Wars (the more recent three), the swordsmanship of the actors is very coordinated and fast. There's lots of aerobatics and fast swordplay; generally impressive (albeit sometimes over-the-top) performances.  But in the original trilogy, Luke Skywalker's swordsmanship appears to be an aimless, desperate swinging motion in nearly every scene. He flails the lightsaber back and forth like a wild boar. It's astounding that Vader didn't quickly put him out of his misery.  Here's what I mean:                                 Is there some sort of explanation as to why Luke's skills are so poor? Does it have to do with the story element, or is it to do with the film itself?

In the , the Imperial forces attempted to blockade any escaping rebel ships.    Clearly the idea of  at least some of the rebel ships wasn't completely off the table.  Yet notably absent from the taskforce was any representation of the .    Interdictors are designed specifically for capturing enemy vessels, employing gravity well projectors to prevent enemy ships from escaping into hyperspace.   They seemed to be a fairly common tool in the Imperial arsenal, at least by the time of  rise, and the Wookieepedia article indicates that Darth Vader used an Interdictor-class vessel as his command ship shortly after the Battle of Yavin.  If one had been present, the Ion cannon defense would not have helped the Rebels escape, and while the Millenium Falcon would likely still have managed to escape, an Interdictor-class ship would have seemed a very useful tool for Vader to have around.  Is there any canon explanation given as to why there was no Interdictor-class Star Destroyer present at Hoth?

Near the end of Star Wars IV: A New Hope, we see four spacecraft flying from the Death Star just moments before it explodes.     As you can see, there is the Millennium Falcon crewed by Han and Chewbacca, a pair of X-Wings which has to be Luke and Wedge, and then in the bottom corner, we see a Y-Wing. Who is this pilot and did he have any screen time to justify him actually existing in this moment? For as far as I can tell during the first trench runs, they were conducted by the Y-Wings and all of them seemed to have been destroyed during their run. So as I asked, who is flying this ship and how did survive to this moment?

As arrows are projectiles, they must use the (large unrotating unintuitive) physics hitbox instead of the bullet hitboxes. So how does the game know where the head is? Is it the same for all classes? How large is the headshot area?

In The Force Awakens, we see the First Order using a new superweapon -- Starkiller Base -- to siphon up the power of stars and use it to destroy multiple planets within that same solar system at a time.   The superweapon portion of this resembles a large Death Star trench, but the rest of the weapon is clearly an icy planet, complete with life (trees, at the very least, and a breathable atmosphere).  So, going by the logic that this has to have been a superweapon using a planet as the base structure, is there any canon evidence (perhaps in the blueprint in the movie or in the novelization) as to which planet it was?

While rewatching Star Wars my skin was crawling while watching Luke practice saber technique against a remote on the Falcon.  There's no way I'd want to be in the same room with a beginner waving a lightsaber around, let alone a beginner with his eyes covered.  Samurai apparently practiced with  to reduce training injuries.  Do lightsabers have lower power settings so that a wrong move while practicing doesn't sever a limb or chop through the hull into vacuum?

In a trailer for Kinect Star Wars, I saw Yoda driving a Jungle Speeder and that got me wondering. Can and has Yoda ever piloted a starfighter?  During the Clone Wars, it seems plausible that they could commission a small-sized green Jedi starfighter. Is their any indication that he has piloting experience?

Since they aren't just light energy (move too slowly), they are probably some kind of matter or semi-matter. It has been speculated that starship fire is of a different nature from rifle fire (different movement speeds, based on movie physics analysis), so is it possible that is also the case for blaster fire vs lightsaber blades?  Reason being, if the two are the same, then why is cortosis specifically just lightsaber resistant?

We all know how to blow up the first Death Star: Fire a couple of proton torpedoes into the thermal exhaust port.  It's ray shielded, so only torpedoes will do.  To do this, the Rebel pilots had to fly down a very long trench, where they were vulnerable to fire from any TIE fighters to the rear.  In fact they were so vulnerable that most of the pilots on this run were blown up once the Imperial forces started responding to the attack. This battle is in space, so the fighters can, if necessary, come to a dead stop and hold their position while firing.  Also, when Luke fired his torpedoes, they took a 90 degree turn and went straight into the port.  So the torpedoes didn't have to be fired from in the trench. We also didn't see any gun emplacements firing at the fighters from near the exhaust port, but if there were, the Rebels could have targeted them and taken them out or run interference to make it hard for the towers to fire at a fighter targeting the exhaust port.  (They were already dodging fire in the trench as well.) A fighter could have easily flown directly at the exhaust port, firing torpedoes multiple times on approach and, if not under fire (or if protected by other fighters), could have actually stopped and taken time to target the exhaust port before firing. Is there any valid in-universe reason that the pilots had to fly down the trench before firing on the port?  And if there is, is there any reason they had to enter the trench so early? Just for reference, here is the  on YouTube.  There's no explanation given for having to fly in the trench.

This is a fun problem that I came across recently, which I'm posting here for your delectation. We all love a good slinky: they can be used for all sorts of fun demos in physics. One example is the "spring reverb" effect, which is well known in the film sound effects industry. If you couple a microphone to a slinky, and then tap the slinky, it produces a wonderful chirping noise. This is actually how they made the sound of the blasters in the Star Wars film franchise.   Watch and enjoy  for a scaled-up example. The slinky in this case is a coil of 3.5mm galvanised steel, 100m in length. A piezo transducer is used to pick up the sound. What property of the coil allows it to produce such an interesting noise?
