...hard science is a part of Star Trek?
Nobody said anything about hard science. jammin said pseudo realistic science / theoretical science, and was speaking relative to Star Wars, which had about zero science content, and Trek did include science concepts that are being worked on today.
It was of course far from scientifically accurate, but you could tell they were at least trying, and it's been cited as an inspiration by many scientists, and has been closely tied to NASA on many occasions because of it.
The new movie doesn't seem to have an understanding of basic gravity and air pressure, or even the concept of distance. Most Trek fans I've seen will be the first to admit that Trek is far from hard scifi, so it shouldn't be all that difficult a standard to live up to, but the new movies don't even come close in that regard.
