Questions tagged [science-fiction]

For questions that allow fanciful, creative or imaginative solutions based on or rationalized by real world science, but not necessary limited by real world science. Entirely magical solutions must use the magic tag instead. This tag should not be used with the science-based, hard-science, or internal-consistency tags. This tag should never be the only tag on a question, because this tag frames how a question should be answered, not the topic.
