^If your being subjected to time dilation you don't need cryosleep. Those thousand of years would pass in days.
The Conestoga Class uses a tachyon phase hyperdrive, which converts the ship's mass to accelerate tachyons. In this phase, it goes much faster than the speed of light, but at 'normal' speeds for people on board. The result is very long periods on the ship vs short periods in the 'real' universe. This is according to the USCM Technical Manual, so call it gibberish if you
must.
She doesn't need the sac to lay eggs, and she had plenty of time to lay it in the dropship gear.
I've done this song and dance so many times I could do it in another language. I could counter every single thing you could
ever say about Alien 3, but this one is the big elephant in the room. If she doesn't NEED it, why does she HAVE it? Why was it clearly shown that eggs were incubating inside the sac? They'd be still born without that, it's quite obvious from a biological standpoint. Look at Termite queens, could they lay eggs without the sac?
But, even if I accept that, the egg in Alien 3 (your movie) is shown placed on a bulkhead,
a bulkhead too small for the queen to fit into.
Even if I accept the queen spitballed the magic Egg, why did it hatch? They have been shown in all the films except Alien 3 that they hatch when something is near.
Even if I accept that (and don't say due to age, the eggs in Alien were 100s of years old and hadn't hatched), how did the facehuggers find them? Aliens use pheromone senses to find their prey as shown by several sources. There are no pheromones ejected from the body when you're frozen. Plus, there's two decks between the dropship bay and the crew quarters. Did they really just get lucky?
Even if I accept that, how did they break through the glass?
Even if I accept that, if the acid blood from Ripley's tube caused the malfunction, why wasn't Ripley's face melted off?
Why did this one drop of acid in a 30,000,000+ cubic meter ship cause so much damage?
Why were there no redundant systems?
Why couldn't it suck the oxygen out from the room the fire was in, a DIFFERENT room than the crew quarters? Or have any sort of fire retardant?
So even if I accept ALL THAT...
why did they not search the ship with a fine tooth comb after the Alien Queen made it on board? They even show in the first scene that they have biological scanning devices. Plus, if you go by Alien 3, it was in a
hallway overlooking the dropship bay! Am I to believe they didn't look to their RIGHT, and instead proceeded directly to go to sleep like everything was OK?
In fact, they probably HAD to scan to make sure there were no hull breeches from Acid blood, especially considering that's how they first noticed the queen in the first place... she was bleeding on the deck.
And even if I believe ALL THAT, there's only one egg but two facehuggers!
GAH!!
KHAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAN!!!!!!
OK, I'm back. I think that's pretty air tight that it couldn't have happened.
