Well, depends if the commenter meant anything that is something we currently not only can't do, but are fairly sure isn't possible. Terminator, BTTF: time travel. Star Trek: depends on the episode (e.g. Q, or the Daud, or time travel). Gravity is arguably contemporary. But yeah, like I said there's a whole category called hard scifi, so no shortage. I just took the ones off the top of my head that definitely were not supernatural.
