No way would that metal flap have sealed the rough entrance they made in the alien structure. Water would be pouring in and would have to be draining somewhere in the structure. Neither going blind nor being poisoned by sea slugs would have been a problem.
Yeah. Exactly. I don't know how it was written in the novel, but I believe there has been some artistic freedom on making this reality. The flood alone would have been terrifying, even though the bacteria, microorganism infestation are real things. The question is, where they did come from in such huge numbers. The answer to that I believe is transpermia, and then evolution. More curious thing, what are they feeding upon, because there cannot be much to eat in the billions of years old alien structure.
I feel there is going to be a huge leap in the material science once they get to really study those structure and take samples from them. The advanced in the computer and analytic devices alone, but so far, we have not seen AI's in control on anything. Not general AI's. It's like it never happened in the Expanse universe, while in the real life, it's already happening and we can expect in 30s some sort of general AI having place in our society.
Another thing is, there are no androids, or even other robots, although they too are becoming more popular in our society. They could have helped with the slug problem. But there was none. Not even on corp side.
I think the pirates destroyed their own ship
Why would you scuttle your own ship? The reactor meltdown doesn't happen in an instant, and it's not a direct explosion. The UN used a railgun to take out the fusion drive, then they shocked the system with localised EMP bursts and possibly malware. The boarding operation was just a cleanup or tag and bag.
The explosion was instant. It was rigged and done by someone deliberately. The ship crew was clearly in shock and scared, while the fighters waited to open fire. Thing is, they took out ship in one go, which suggests that they had placed explosives everywhere, or then the bomb was humongous, suggesting the fusion drive.
A nuclear device could have done the damage, but where would they have got one, when Johnson surely didn't give them any. Did they got something from Mars?
