December 04, 2013"Science fiction is largely based on writing rationally about alternative possible worlds or futures.[2] It is similar to, but differs from fantasy in that, within the context of the story, its imaginary elements are largely possible within scientifically established or scientifically postulated physical laws (though some elements in a story might still be pure imaginative speculation).
The settings for science fiction are often contrary to consensus reality, but most science fiction relies on a considerable degree of suspension of disbelief, which is facilitated in the reader's mind by potential scientific explanations or solutions to various fictional elements. Science fiction elements include:
A time setting in the future, in alternative timelines, or in a historical past that contradicts known facts of history or the archaeological record.
A spatial setting or scenes in outer space (e.g. spaceflight), on other worlds, or on subterranean earth.[3]
Characters that include aliens, mutants, androids, or humanoid robots and other types of characters arising from a future human evolution.
Futuristic or plausible technology such as ray guns, teleportation machines, and humanoid computers.[4]
Scientific principles that are new or that contradict accepted physical laws, for example time travel, wormholes, or faster-than-light travel or communication (known to be possible but not yet feasible).
New and different political or social systems, e.g. dystopian, post-scarcity, or post-apocalyptic.[5]
Paranormal abilities such as mind control, telepathy, telekinesis, and teleportation.
Other universes or dimensions and travel between them...etc. "
Interesting reading that from wiki. And the comments here it seems the lovers of prometheus seem to generally not need it to make scientific sense which is lucky as allot of it doesn't. The haters being the opposite in general. Yet the very definition leans towards it being plausible scientifically lol! Alien was pretty much close to being totally plausible in every aspect that is why it is so highly praised and wondered at. It is its plausibility that makes it so. Prometheus has so many unplausible parts its hard to see were one ends and another starts. This is why a year and a half on most people still do not rate it anywere near alien. Its not going to change with time lol! So yer scientific plausibility is part of the very definition of sci fi well at least the straight up good sci fi. Interesting I never realised so many dont need it!
"It's almost as if they are making it up as they go along" :D
