Just saw Arrival and have some questions (SPOILERS)
SPOILERS AHEAD:
1. What did Abbott say to Louise on their last visit? I saw this while abroad in the Netherlands and couldn't fully understand the Dutch subtitles. Something about Costello having died, then the humans help the heptapods 3,000 years in the future? I can't remember if there were also subtitles I missed during the General Shang phone call scene.
2. Please correct me if I'm wrong on any of these premises I took away from the film:
A. Time is non-linear and cannot be changed, so even though the heptapods and Louise have the ability to experience the future, they cannot change it, hence Louise's daughter and Costello's death. Which kind of suggests that nothing in the universe has free will, everything is just following a predetermined path.
B. The heptapods came to earth because they had to fullfill the paradox of their own future by giving humans the ability to see the future, so that it would unite the human race (perhaps preventing us from destroying ourselves) so we could in turn help save the heptapods 3000 years into the future.
C. The heptapods gift to humans is teaching us their language which in-turn rewire's our brains with the ability to experience non-linear time and see the future. So the heptapods were basically teachers, and perhaps could have wrote in our language the whole time, but needed to get us to learn their language in order to rewire our brains.
D. Louise's brain gets rewired, does anyone elses? Seems as though Ian's never gets rewired even years into the future, since he doesn't believe Louise when she tells him of their daughter's future death. Does the book Louise writes rewrite the brains of those who read it? Was she spreading the heptapods gift to the rest of the world via the book? EDIT: I think I understand the sequence of future events better now:
- Heptapods come to earth: goal give humans the ability of non-linear time.
- They succeed when just one person, Louise gains the ability.
- It takes years for Louise to fully decipher the heptapod language, so for perhaps 15 years she is the only human with non-linear time abilities, hence her separation from Ian.
- After her daughter's death, she releases her book, which is the sum of the gift heptapods gave humans... non-linear time abilities spread around the world.
3. Anyone know if there's any scientific basis for the time paradoxes we see in this film? From what I understand it's impossible to send information back in time. So Louis being able to get information from the future General Shang to influence him in the past breaks fundamental quantum mechanics as it relates to making decisions and observing their outcomes. I read that the quantum eraser double slit experiment proves that sending info into the past is impossible, the universe is built to prevent time paradoxes. But perhaps perceiving non-linear time could be scientifically plausible if it shows that no decisions are ever made, they've just always and already have been made and we're just along for the ride, following a predetermined life with no real control of our own. Seems like a depressing gift from the heptapods if you can see your future but not change it.
