What I find interesting is in Interstellar the astronauts flew away from Earth in the usual old fashioned way… ROCKETS… but they flew off the 2 other planets using their small spacecraft. Apparently only at Earth, rockets are needed. I see that happening in other sci-fi movies as well.

It would be a hell of a lot easier for them to just fix Earth but then we wouldn't have a space movie. None of the planets they found are particularly good, which I think is the point of the film. We have one home and we have to protect it.

The problem I have with the first planet is they treat time dilation as only happening on the surface, yet they would have been experiencing basically the same thing while they were in nearby space

[ychang]

Miller's planet, while makes for an amazing set piece, the fact that they even considered it for a colonizable planet is nuts. You would see from orbit the monstrous tidal waves, and the fact that the scouts would know that even if they could colonize a completely landless world, any colony there would be permanently time dilated and would be trapped in the gravity well of the black hole.

Hi Alex McOlgan, thanks for putting a spoiler warning on a ten year old movie you've covered multiple times. You're doing a better job than 80% of youtubers out there by doing so. Sincerely, Watching Astrum.

For this longtime fan of the film that was a really fun grand tour, Alex. I especially appreciate how carefully you looked at the science behind the exoplanets depicted without ruining the movie as an accomplished piece of sci-fi filmmaking and storytelling.

[dumpstercat]

Ah yes, the classic, "Earth is becoming uninhabitable. Lets find an already uninhabitable planet and jump through extreme hoops to build a biodome there instead of building one on earth."

[Flesh_Wizard]

The first thing I noticed was the proximity to the accretion disc. Imagine the radiation ☢️

[MeesterG]

If you like realistic sci-fi stories I can recommend some books:
Project Hail Mary - Andy Weir (same writer from The Martian)
Dragon's Egg - Robert L. Forward
Rendezvouz With Rama - Arthur C. Clarke (slow first book, but I great series)

Project Hail Mary was the best book I've read in a long time. Definitely recommend that one ;)

If gargantua is really a SUPERmassive black hole, then there is no possibility of any sort of "blanet" orbiting it. Blanets have to do with stellar-mass black holes. Also, its overwhelmingly likely that any black hole with an active accretion disk would render the habitable zone of the system far outside of the black hole's gravitational domain. Water would never exist in such systems.

Blanet

A blanet is a member of a hypothetical class of exoplanets that directly orbit black holes. Blanets are fundamentally similar to other planets; they have enough mass to be rounded by their own gravity, but are not massive enough to start thermonuclear fusion and become stars. Wikipedia

It's possible that Edmund's Planet is more Earthlike than it seems at first. After all - we only see a TINY area of it around the Campsite/Colony in that Desert area. But - as we should know by now - Earthlike planets don't only have one type of biome. We have deserts on Earth as well. But we also have forests, jungles and oceans. It's possible that Doctor Brand decided to start that colony in the desert area for consistency and safety. She can always use the lander to fly to other areas to explore. If there are any dangerous lifeforms in those other areas, they may be confined to those areas. If there are LARGE lifeforms like Dinosaurs, then they probably won't cross the desert to threaten the camp.
Let's hope there are no Arrakis style sandworms in that Desert!

1. Mars is much closer than any of other planets. Why not colonize Mars instead?
2. We see in movie that some parasite destroy soil. OK. But also, if we were able to lunch orbital habitats with clean soil, it means we can clean up soil. Why not make isolated habitats on Earth, much cheaper than lunch and place it near Saturn (where Sun light is very good for that is separate topic)

[masaharumorimoto]

Coop and Brand just chillin havin a heart to heart while Doyle is right there rescuable and likely not dead just K.O'd lol.

[Pixeleyes]

I love this movie but nothing about the blanet made a lick of sense and starkly contradicts every prediction ever made about the subject. That said, it was pretty awesome anyway.

[keiththorpe]

Actually, none of the planets around the black hole need to be colonized. Once the technology was perfected to allow humanity to escape Earth and live within O'Neil Cylinder-type colonies, it would be completely viable to remain in our own solar system. By utilizing the resources found on the planets, moons, asteroids, and comets throughout our system, we could build a vast network of these habitats, creating a solar system-spanning, space-faring civilization.

[funnelvortex]

Also don't forget: time dilation magically turns off in orbit but turns on when walking on the surface. Like that guy aged like 20 years or something even though he was in orbit of the same planet that the other characters experienced time dilation on. A lot of things about this movie make zero sense, which would be fine if the movie and it's fans didn't advertise it as being super big brained hard scientifically accurate and just embraced it for the fun science fantasy adventure that it is.

[foxlimey]

Many studies have actually shown that planets with atmospheres and oceans would be able to redistribute heat pretty well. Ocean worlds in particular would be extremely good at heat redistribution, so depending on the temperature of the planet both the day and night sides would remain completely ice free. Also many models show the day side of tidally locked worlds may be extremely cloudy.

[beskamir]

My main issue with this entire film is that all the candidate planets require some amount of terraforming and if that's possible then why not do the same on Earth so there's never a reason to have to leave in the first place? They even have a fully functional space habitat yet still fall back down a gravity well for unknown reasons... It's been a while since I saw the film so I might be missing some other issue that'd require them to abandon earth.

I actually did a whole essay on this movie for a film studies class in college. Nolan did his best to employ real scientists and astronomers to make the movie as realistic as he could. If you have the deluxe DVD, it comes with a whole documentary about this work with experts and animators in creating the movie
