Good thread!
One question I always had: Why do the alien warriors from Aliens look different from the first Alien in the previous film? They're both born from humans, and since aliens take on characteristics of the host, wouldn't the aliens look the same from both films? Was it just Cameron's decision to make them "warriors"?
There's no scientific explanation. It's just Cameron who wanted the dome to be removed because it would break during the action sequences.
