Some interesting stuff I read and didn't think about, spoilers ho and all that jazz
- the solo arm wasn't sentient, it was being controlled by the guy in the other universe. Presumably the guy we saw was controlling one arm in the other universe. Yeah that really doesn't make much sense.
- the room where the chinese girl (she's from Crouching Tiger btw) was started filling up with water because the space station crashed into the ocean in the other universe
- the magnet stuff suddenly happened because the other station was being lifted out of the water with cranes
- the man briefly interviewed on Earth TV is the brother of Howard (Goodman) from 10 Cloverfield Lane
- the reporter lady interviewing him dies at the start of 10 Cloverfield
- there is a bright red flash the final time the accelerator is used, it occurs i guess somewhere in 10 CL too
I wonder if there are any easter eggs with the little girl that gets rescued, cuz that entire sub plot seemed completely unrelated to everything except they were in a bunker
