TrueDosGamer: The wording at the Star Wars intro could be looked at as a swapping of words from a fairy tale opener. I think I remember hearing George Lucas describe Star Wars as an opera in space. But the very definition of science fiction is what I was trying to get at. If this was Peter Pan flying around magically without any form of technological propulsion except to think it and he could choke someone with telekinesis then yeah I would say this is more a fairy tale than science fiction. But you see most of the things set in that Star Wars universe shows a technological foundation. Vader isn't floating around sprinkling pixie dust onto Luke to try to persuade him to the Dark side. Han Solo isn't throwing magic potions at the Storm troopers to make them vanish. He's using futuristic weapons which appear to have a technological foundation to present day. For example guns to laser guns, metal swords to light sabers, the NASA space shuttle to the Millennium Falcon, and the International Space station to the Death Star.
While I will agree there is some non science fiction invading Star Wars with the whole telekinesis and mind control but had this been set say during the medieval times and you had guys swinging real swords and wizards using magic potions allowing them to appear anywhere then yes I think that would shift it towards the fantasy world a bit. But there is so much futuristic technology within the Star Wars universe that it overshadows it being categorized as a fantasy or fairytale. Even Darth Vader is revealed to be part machine if I remember correctly when he removes his helmet.
Navagon: If everything in fantasy had to be entirely fictional then most fantasy wouldn't fit the description. Describing Star Wars as fantasy doesn't mean there's pixie dust in it any more than Game of Thrones is a historical drama because it has swords and bows in it.
We can, in science fiction assume certain technologies will be developed (such as energy weapons) without having to lay down a solid scientific basis for their operation - so long as it seems reasonable that such things could in future exist by current scientific understanding. We can take a look at the way technology is progressing and make assumptions based upon that.
That's why it was perfectly reasonable back in the late 60s to assume that by now there would be Martian bases, ray guns and an apocalyptic nuclear war with Russia. But today none of those things seem likely to happen in the next 50 years.
As for your examples, the light sabre doesn't seem feasible given the problems we've already discussed. Even if there are energy weapons, they'd either still be centred around a physical projectile or they'd be beam based. Meaning there'd be a continuous unbroken beam from the barrel of the weapon to the target. Not the blasts we see throughout Star Wars. I don't know what those are supposed to be, but they're not how lasers work.
Equally, the Death Star's multiple beams into one weapon doesn't really make sense when they're all coming in at angles like that and redirecting each other to a single shared target. Overlooking the ridiculous energy consumption, how would that work?
But the real problem I have with your argument is that you're arguing that Star Wars is bad. I can't agree with that.
Science Fiction itself has a bit of fantasy - like daydreaming about what could be. But you said "It's swords and sorcery set a long, long time ago. Which is fantasy."
I'm a little confused since you don't think it is science fiction when the entire universe setting is set at least from our perspective sometime in the distant future as I don't see us having anything remotely close to the technology seen in those movies happening any time soon in our lifetime unless something dramatic happens like an alien lands on Earth and decides to enlist humans for space traveling and share their space faring technology with us similar to what happened in Star Trek : First Contact. One day certain things in science fiction no longer are because we've achieved that technology. For example in Star Trek there is a gadget called the communicator. It allows someone to communicate with someone wirelessly over long distances. Well today we have that. It is called a cellular phone. Those memory chips you see and those square objects we had those too. They are called flash drives and floppy disks. We still haven't achieved a space ship fleet, transporter technology, light speed travel, meeting new alien species. But the idea that at one point in time they were science fiction and later have become science fact from technological progress. But the big ones are still there and haven't been achieved.
No one says they have to constantly focus on technology in order for it to be science fiction. It's the background setting that qualified it to be science fiction. Star Wars could have put a date on the intro sequence but Lucas chose not to so people would fantasize about the what if... If he time stamped it and said "A long time ago in a galaxy far, far away in the year 2100". That would tell you something. The space opera is set at a future time and 2100 would still be in the future for us. By him leaving out the actual date he keeps us guessing and it also helps the movie not feel dated if it were watched in the distant future where we still haven't achieved that technological level. But one day let's say the year 8500 human civilization has exceeded everything capable in that movie technologically. They will be laughing at this movie. Sort of how people of today would look at Westerns. It doesn't impress us since we drive cars and fly airplanes while they have horses and trains. Maybe in year 8500 they've figured out teleportation over long distances so the need to use space ships has become obsolete.
Science fiction has a bit of fantasy embedded within because it hasn't happened yet.
My examples were to correlate past technology with science fiction future technology. Whether or not it will be achievable 20,000 years from now we won't know. The point is you can't exclude the possibility that it won't happen or some form of it. We won't live that long to see how far technology advances in the future. Even if the Star Wars ideas may not be built on good science we can't blame them and say it won't happen.
Check out the movie 2001 : A Space Odyssey. It was shot before we were in space. They talked to scientists to get real science put into the movie of how things would be in space. The circular artificial gravity station is something that could happen in the far future. The Hal 9000 Artificial Intelligence was something of science fiction but today we are approaching the level where basic AI might be within our lifetime.
As far as Martian bases, that's coming up within our lifetime in 2027.
https://en.wikipedia.org/wiki/Mars_One I'm not sure where you saw me type this, "But the real problem I have with your argument is that you're arguing that Star Wars is bad. I can't agree with that."
However after your analyzing the science in Star Wars it appears to you it is built on bad science or wasn't thought out thoroughly. I can't disagree with that. I myself don't think that light saber seems like something that would happen. the fact that it shoots out from the handle. If it was one solid stick and the energy formed around it it would make more sense. I suppose they could make it a collapsible weapon when off and when on it shoots up sort of like those radio antennas. However I can see a Star Trek phaser might be possible since it is a form of energy being projected. Who knows what kind of laser technology would be possible in the future and we all know lasers when focused can cause damage. A taser does the same thing in a concentrated form. Now the stuff I've watched in the past was usually the Star Trek shows where they do make an effort at using a lot of real science in it to predict what might be possible. I never studied the science in Star Wars as I'm not obsessed with Star Wars and there have mainly been movies and no TV series to explore the science. Watching the movies as a kid I did feel it was for entertainment and you don't really focus on the science fiction. However, I still can't say Star Wars is all fantasy and not science fiction. But there are fantasy elements in the movie using science fiction.
The whole Death Star must have been a major undertaking to build and harness all that power but do I think that is something that would be built? I would say no. But when you watch it as a kid you accept it and don't analyze. Do I expect everything in science fiction to happen? No but these are ideas and when someone sees your idea one day as a kid they might continually fantasize about it and try to create it. One day I predict we will be watching movies in theaters using holograms so they are more interactive instead of just in front of you on a 2D screen or wearing 3D glasses. This is science fiction now but there will be a day this will happen and when that day comes people will be wondering how Gramps could stand watching 2D movies or virtual 3D instead of Holographic movies.
