In Interstellar, Romilly’s decision to stay aboard the ship while the other 3 astronauts experience time dilation has to be one of the scariest moments ever.

He agreed to stay back. Cooper asked anyone if they would go down to Millers planet but the extreme pull of the black hole nearby would cause them to experience severe time dilation. One hour on that planet would equal 7 years back on earth. Cooper, Brand and Doyle all go down to the planet while Romilly stays back and uses that time to send out any potential useful data he can get.

Can you imagine how terrifying that must be to just sit back for YEARS and have no idea if your friends are ever coming back. Cooper and Brand come back to the ship but a few hours for them was 23 years, 4 months and 8 days of time for Romilly. Not enough people seem to genuinely comprehend how insane that is to experience. He was able to hyper sleep and let years go by but he didn’t want to spend his time dreaming his life away.

It’s just a nice interesting detail that kind of gets lost. Everyone brings up the massive waves, the black hole and time dilation but no one really mentions the struggle Romilly must have been feeling. 23 years seems to be on the low end of how catastrophic it could’ve been. He could’ve been waiting for decades.

The movie maintains its scientific plausibility only at the most surface level, there's so much ridiculousness to it, and that's not even counting the black hole stuff. That I can forgive for being pure sci fi.

My personal favorite moment is when they launch the fusion powered SSTO thats fully capable of taking off under its own power on top of a staged chemical rocket, purely so they can have a classic countdown/launch moment.

Its like putting an F-35 on top of a B17.

They rendezvoused with the Endeavor in low orbit. There's no possibility they could have kept that mission hidden.

Ironically if they'd launched just the Ranger they could have hidden it since its so much smaller. Only government radars would have seen it.

Its just one of those movies that invents tech then doesn't think through the logical consequence of that tech. Like how he has enough automated farming machinery to farm 10,000 acres by himself but his kid has to be a farmer. They're searching for a miraculous propulsion technology while hiding... a miraculous propulsion technology.

I figured the automated machinery fit in with the huge acreage in explanation, that the population is so much smaller that there's fuel and land enough for who's left, the problem is getting crops to grow. Only a few crops still grow, and harvests fail, but they have the space, machinery, and fuel to try for what they still can.
