Sci-fi in General.
Sound in space.
People EXPLODING in space
Shouldn't you be bugged by people on screen
not exploding in space? Because exploding bodies is what you would realistically see if they're in a zero pressure environment...
Heroes: Not only do eclipses happen all over the planet at once, but they make you a mutant and turn your mutant powers on and off like a light switch.
Star Trek: The galaxy is brimming over with Earthlike worlds and most of them just happen to have evolved bipedal mammalian humanoids as the dominant life forms. The first person to mention The Chase gets smacked.
Heroes and
Superman and, yes,
Star Wars are fantasy to me ... superpowers and a magical "Force"... so I don't expect even pseudoscience from them.
As to Star Trek's humanoid aliens, I have an explanation that doesn't involve The Chase: there are as many non-humanoid aliens in the ST universe as there are humanoid ones, but we virtually never cross paths with them. Their "habitat" and their needs are so different from ours that there are no points of competition, cooperation or trade that would make contact necessary. We're too different to have a meaningful interaction. We don't have anything they'd want or need, and vice versa. Our thought processes and language structure are probably too different to make communication possible. So, there are no stories to tell about "them and us".
1) Sound in space
2) Aliens speaking English
<snip>
Recently, 2) is often solved with some technobabble plot device such as universal translators (Star Trek) or translator microbes (Farscape).
Nerys Ghemor's explanation of the UT as a cranial implant that changes the receivers' perception of the language by working directly on the speech center in the brain made the most sense to me (in case I interpreted her concept incorrectly, check out her "Sigils and Unions" on the FanFiction subforum where it's explained).
But hearing alien languages with subtitles would definitely be more fun. And the UT
shouldn't be working at first contact, because even with Nerys' concept, that's just impossible.
- People being able to dodge lasers, phasers, etc., at fairly close range.
- Inertia dampers
- The idea in Space: 1999 that an explosion on the dark side of the Moon will cause it go flying into deep space rather than crashing into Earth.
1) Oh yes!
2) Inertial dampers = artificial gravity. So if you don't want them, you'd have to do away with the concept of AG entirely, which means people drifting in zero g all the time. That would make watching the show akward (at least for me... I have a sensitive stomach); besides, then you'd have to deal with all the medical side-effects of extended stay in a zero g environment and that's not a story I'm interested to see.
3) :facepalm:
But I've got another one: Spaceships which don't move like objects in vacuum/zero gravity. This includes spaceships which slow down or stop when their engine fails or is shut down, two-dimensional naval battles in space, and of course the fighter-plane analogy popularized by Star Wars (although B5 and nuBSG tried to do away with it by finally introducing fighterplanes which move like in vacuum/zero gravity).
Thanks, now I have a new detail to rant about that I never noticed before!

The 2D battles were more a nuisance because they were so incredibly
lame and I'm glad they got over that now.
But really, just what the hell is the point to this thread? Silly science is a requirement for sci-fi. If you had a complete 100% realistic sci-fi show or movie, it would be boring as hell. Not to mention the fact that with no FTL, that pretty much prevents a show set in space from happening.
Nobody asks for 100% realism, but stupid, glaring errors such as
sound in space could easily be avoided. I think that cutting between scenes of silent battle from a space POV and scenes from inside the ships where you have thos
loud explosions, people screaming, etc. would be
more dramatic by this contrast.
