100 Things we learned from "Arrival."
Well, SOMEBODY had to do it.
1: In a distant galaxy, the most intelligent beings live in a liquid environment, yet they are able to fabricate things out of metal & other hard materials.
2: Those intelligent beings look very much like the Earth's squid, and amazingly they will create dark ink just like Earth's squid, even though they don't share a common ancestor.
3: Those intelligent beings, despite being emersed in liquid, can somehow create stable, complex designs with their ink, and those designs don't even move around, although the liquid certainly does!
4: The female human, once she is immersed in their liquid world, (without drowning, no less) will somehow be able to make the same exact inky circles, even though her ancestors are neither squid nor Heptapods.
