"I don't really see science fiction as fiction. I can imagine colonies on Mars and everything"

Sigourney Weaver's quote suggests that she views sci-fi as a potential reality, instead of a form of fiction. She thinks that it is possible to imagine colonies on Mars and other futuristic principles, and that these ideas are not just the item of an imaginative mind. This could be translated as a sign of her optimism and belief in the capacity of science and technology. It could also be viewed as a reflection of her faith in humanity's ability to explore and innovate, and to push the limits of what is possible. Her quote is a suggestion that sci-fi can be seen as a source of motivation and a method to check out the possibilities of the future.
