Apparently in the future according to Fede Alvarez and Alien: Romulus acid-bleeding aliens aren’t the only things that don’t quite make sense (I can see no reason for the Alien to have acid for blood and it has been a part of their mythology that’s always bothered me. It’s clearly an apex predator and such an ability comes off as little more than overkill. The Facehugger? In that instance it makes more sense because when they’re doing what they do, they’re defenseless).

Apparently momentum works a bit differently in the future as well because when the mining hauler Rain and Andy used to escape Romulus station lost power (and seemingly speed) its flight path began to degrade, slowing dropping into the rings of some planet and its destruction.

I’m not a math person by any stretch of the imagination but shouldn’t their ship have simply continued on its flight path – whether it were on autopilot or not isn’t relevant – since the momentum the ship had already built up should have been enough to have it continue.

Now if the ship were let’s say fighting the gravity pull of the aforementioned ringed planet I could understand a degradation of its orbit, but since the narrative mentioned no such thing – which if it were the case would have been fairly easy to do – it just sounds like the mining hauler lost momentum because ‘movie.’
