Dragons’s Egg [1] is a great sci-fi novel that explores this concept in the other direction.
Humans are the slow ones and the Aliens are creatures living on the surface of a neutron star. Humanity makes contact and generations of the aliens live, die, and develop technology over the course of several subjective days for the humans.
Time Trap is a campy sci-fi movie that explores a similar concept, teenagers get trapped in a cave where time elapses differently. Not highly recommended, but it’s good fun.
Oops. You're right. I remembered it as TNG and didn't notice when I looked up the episode name. Wikipedia says "believed to be inspired by" but it would surprise me quite a bit if it weren't.
I didn't love Voyager overall but it had some pretty good episodes scattered throughout.
Humans are the slow ones and the Aliens are creatures living on the surface of a neutron star. Humanity makes contact and generations of the aliens live, die, and develop technology over the course of several subjective days for the humans.
Highly recommend giving it a read~
