Hi everyone - I'm new here. A quick question, if that's OK (I'll have more, don't worry)
Why does everyone complain that a lot of space movies show things happening in space and also have sounds of laser beams, spaceship engines, etc?
I know that sound doesn't travel through a vacuum, but so what?
Imagine that we have two charecters in spacesuits, floating around outside a spacecraft. We see them from about 100m away. They are having a conversation.
No-one would ever complain that we could hear what they are saying because we apparently have 100 metres of vacuum between us and them. No-one has EVER complained about this, it's only ever laser beams, etc that cause people to bring out the "sound doesn't travel in a vacuum" rant.
Of course, technically we should move the camera point of view to a point INSIDE of one of the characters spacesuits, where the air in the suit can convey his speech to our POV. I don't think that a closeup of his nose from about an inch away would make for fantastic cinema, though.
You don't even have to go into space to see this: it's common to have movies where you see two characters walking romantically down a beach, for instance (I don't watch a lot of movies like that, though :-) ). Even though our POV is, say, at the top of a cliff, or obviously in a helicopter, again, it seems quite reasonable for us to hear them speaking. Even though we have air all the way between us and them, there's no way we could hear them from a helicopter.
So, in the case of a spaceship moving past the camera, I can accept that our visual POV is hundreds of metres away, with nothing but vacuum, between us and them. Why can't our auditory POV be inside the ship though? There would presumably be some pretty funky engine noises in the engine room. Any bits of the ship that had just been drilled through with a laser would presumably have had some noise to contend with, no? So isn't it reasonable to show us some sounds from the POV of humans inside the ship? Most (if not all) movies are told from a human point of view, after all, it seems reasonable to include those sensory stimuli that are relevant to us.
You might as well complain that you went to a cinema and the projected movie had only visible light present in it. Everybody knows that space has cosmic rays, UV, etc, that aren't present inside the earth's atmosphere in the same quantities. Don't the filmmakers know this? Are they trying to insult our intelligence by not including hard radiation?
Sorry for length of post, it's bothered me for years, I'll calm down now.
