A collection of science fiction movies and television shows that attempt some degree of scientific accuracy, with technologies or scenarios that may be nonexistent in today's world but are at least realistic (if only theoretical). That is to say, they don't rely on magic or fantasy (or anything that departs significantly from mainstream theory) to propel their plot.
This is not to say that some of the line-up here don't take a few speculative leaps, but they at least begin from a place grounded in credible research and theory, from where they then develop their more extravagant premises.
Yes, listing time travel films here is a cheat, but I've only included a few, and only those that make some attempt to explain their paradoxes and/or take their temporal consequences seriously.
