I was thinking a little bit about older science fiction, like ones involving space travel, exploration, etc.
I miss how these older shows and movies drove home this feeling of.. utter vastness of space. I'm pretty sure it was a fortunate byproduct of just how it was difficult to do effects back then. Now, sure why not throw in hundreds of ships orbiting a planet. But in the 80s? One of these ships would be out there, in the unknown edges of space, and it REALLY felt that way because you hardly ever see anything else.
Interstellar did a great job with this; the crew in that movie feel incredibly isolated.
Anyway, that's my random #space thought of the day.
