That's exactly what I believe, boobamiaow. I think some research is always required, even if you're dealing with a subject you know really well. And I think a concept has to make sense or be semi-plausible in order for people to suspend disbelief in the first place. I mean, you can think that something (e.g. a Stargate) will probably never exist. However, you might believe that something like that could at least be possible if we ever leapt that far in terms of scientific advances, etc.
