Yes, the Christopher Nolan wet dream that became the film "Interstellar" (2014).
Ok, plot holes aside, and there are many, the film tries to make sense of the concept of relativity and the implications of it.
The film, by itself, handles those concepts rather well. But BOY, does the lead up provide more questions than answers? You bet it does!
Putting up with the plot holes is the obvious answer to watching this film.
But if you can get past that, the rest is a great essay on the effects of time travel.
As complicated as it may be, this film actually and correctly shows the implications of "close to light travel" and the practical problems that result.
The plot holes are confounding and infuriating.
But the result of the film is that of hope.
