It is a pity they didn't spend comparable effort on the story. I thought it was a really disappointing film, especially after they banged on so much about how good the physics in it was (apart from the black hole rendering, it wasn't).
- guitarlimeo 2y agoDid we watch the same movie? They got bunch of physics stuff right, like the water planet, the relative aging due to being near the massive black hole etc. Only thing that wasn't "correct" was the wormhole and especially the tesseract, but that was some creative writing which allowed for a nice twist. I enjoyed it, a nice scifi.
- kawa 2y agoTheir starship was bullshit. On earth they needed a big Saturn 5 like rocket to bring it into space and later they fly into orbit like it's nothing. If the planets they visited had much lower gravity then earth this may be possible, but this wasn't noticeable or talked about. And even on Mars you need much more fuel to get into orbit than could be stored in their tiny ship.

- AlexGizis 2y agoTo expand on this, if they tried to land on the water planet where time so dilated that one hour equals 7 months… what would their velocity have been when they contacted the surface? And how much energy did their spaceship need to reach escape velocity from there?
- wizzwizz4 2y agoEh, this isn't actually that bad. It's quite easy, using a jet aircraft, to (via a ballistic trajectory) get into space. Surrounded by reaction mass as you are, the rocket equation isn't nearly so bad. You could conceivably dock with something in orbit, if you had elastic tethers or something to make the acceleration survivable. If you're much lighter than what you're docking with, you won't knock the satellite out of orbit. Heck, you could even ignore the jet aspect, and go for full rocket. (An ICBM only weighs around 50 tonnes, after all.) Getting the heavy thing into orbit, though, requires proper, multi-stage rockets.
- hermitcrab 2y ago>It's quite easy, using a jet aircraft, to (via a ballistic trajectory) get into space A jet engine requires atmosphere. Spaces requires no (or very little) atmosphere. The edge of space is usually defined at 100km (the Karman line). The highest altitude reach by an air breathing jet is around 37km. https://en.wikipedia.org/wiki/Flight_altitude_record https://en.wikipedia.org/wiki/Flight_altitude_record A scramjet might get to ~75km according to: https://aviation.stackexchange.com/questions/44837/what-is-the-highest-operational-ceiling-for-an-air-breathing-jet-engine https://aviation.stackexchange.com/questions/44837/what-is-t...
- wizzwizz4 2y agoThat's the point at which the jet stops working, but by that point you can be going quite fast. If there isn't enough air to run the jet engine, there also isn't enough air to slow you down (much).
- hermitcrab 2y agoAssuming no air resistance and 10m/s^2 gravity. I calculate that you would have to be doing ~1,100m/s (~mach 3.2 at sea level) straight up at 37km to reach 100km. Or ~1,600m/s (~mach 4.7 at sea level) at 45 degrees to perpendicular.
- wizzwizz4 2y agoSeems about right. https://en.wikipedia.org/wiki/Project_HARP https://en.wikipedia.org/wiki/Project_HARP (1966) got 2100m/s from a ground-based cannon: this got the projectile to 179km.
- GTP 2y agoWell, if you look for this, many if not most movies will have some inaccuracy or holes in explanation like this. In the end, I watch movies for entertainment. If I'm looking for scientific precision, I see a documentary instead.
- hermitcrab 2y agoYes. Maybe don't make scientific accuracy a big part of your marketing campaign though.
- m4rtink 2y agoStill better than what Ad Astra! :D Liked the killer space monkeys though. ;-)
- hermitcrab 2y ago'Ad Astra' was a real stinker.
- tambourine_man 2y agoThe whole premise is bogus and explained by Michael Caine in only a few sentences. We have a plague on Earth and doing an interstellar travel is the solution? I was very disappointed. I’m OK with a few plot holes, but this is so fundamental to the story that the movie can’t stand on its own.
- marcyb5st 2y agoYeah, they could've used something simpler and less hand-wavy. Irreversible climate change or a freaking asteroid on a collision course with earth and they needed the black hole data to build something to deviate it. Literally anything else would've worked better.
- throw310822 2y agoI think the blight was chosen as a metaphor for the virus of defeatism and anti-scientific attitude. To which the movie proposes (and arguably wants to be) a cure, made of optimistic sci-fi, cool science and, of course, love. The issue on the literal level of the narrative is that if you have no way to control the infection on earth, there's no reason to suppose you won't bring it with you to the next planet.
- bhickey 2y agoIt was completely uneven. Cooper sobbing as he listened to years of messages from his family? I wish I could've written that. The twist where Mann activated his beacon because he didn't want to die alone? Solid. We need the gravity equation to get off Earth because the crops are dying? Love can escape a black hole through the tesseract? This is just patent technobabble nonsense. Where _Interstellar_ fails is in exposition. Love is the most powerful force in the universe? The Fifth Element pulled that off by not pretending to be serious. Anything is permitted in science fiction, but once you commit to explaining it, you need to make sense.
- bowsamic 2y agoI agree, in fact it almost gives it a sense of uncanny valley
- wombat-man 2y agoYeah I agree. Overall I still like it but I need to overlook parts of it.
- ralferoo 2y agoPlus it helps that Fifth Element has that scene... where the General "would like to take a few pictures... for the archives"!
- actionfromafar 2y agoIt can still make some sense, if you think that the future life forms expressed their inherited love to fix things way back in time.
- rbanffy 2y ago> We need the gravity equation to get off Earth because the crops are dying? The small craft could launch from a planet with twice the Earth’s surface gravity, make it to escape velocity, and meet the Endurance? Why would they need better propulsion than that to leave the planet and build space habitats?

- anentropic 2y ago100% agree, like you I was hyped after the pre-release teaser PR stuff came out about the realistic black hole rendering etc, was hoping for an actually decent sci-fi and then just a lame story culminating in "space ghosts" for me, arguably most disappointing movie ever
- hermitcrab 2y agoDon't watch 'Ad Astra' then. That's also incredibly disappointing (IMHO).
- actionfromafar 2y agoIt's all about the expectations. The SciFi part is just a setting in this one.
- m4rtink 2y agoNot if you take it as a comedy - then the buggy joy ride, monkey station & space surfing make perfect sense. ;-)
- hermitcrab 2y agoMaybe I should have watched it in a state of inebriation. I don't think I could face a second attempt at it.
- throw310822 2y agoWe're talking about a movie in which a space agency builds an enormous rocket entirely in secret and without any suppliers; then enrolls the astronaut at the head of the mission on the same day of the departure; and finally launches the rocket from inside its office halls. ¯\_(ツ)_/¯ https://www.youtube.com/watch?v=x9xFRch7N5o https://www.youtube.com/watch?v=x9xFRch7N5o
- actionfromafar 2y agoWell, if the launch fails, they won't need the office anymore. If the launch succeeds, same.
- hermitcrab 2y agoIt also hard to believe that being close enough to a giant black hole that it causes massive time dilation, doesn't seem to cause any other issues beyond large waves.
- hermitcrab 2y agoThey obviously used the same contractors that Bond villains use to build super bases inside volcanoes without anyone noticing.
- throw310822 2y agoIndeed. https://youtu.be/tDedpreZH-0 https://youtu.be/tDedpreZH-0
- VyseofArcadia 2y agoIncredible soundtrack, though.
- Qem 2y agoAlso the robots were cool.
- hermitcrab 2y agoThe robot's form of locomotion seemed rather daft. But it was at least original.
- m4rtink 2y agoI think its just how "regular" fractal robots work in general ? :)
