Okay so I looked more into the design of his "ship" with it being apparently a subject to actual physics of space, and boy is it fucking awful.
First of all, it's completely asymetrical. While that on itself isn't that much of an issue, it does become an issue when the supposed cargoholds are full. Frontal cargo hold is much bigger than the one at the aft, and suddenly you have pretty big difference you have to keep in mind. The centre of mass suddenly moves, and it's not between the both cargoholds, it'd be somewhere within 1/3rd of the forward hold, and suddenly you have two axes of movement inside. Gravity would be extremely uneven, as weak as it would be anyway.
Then, we have the sensors. Both forward and aft sensors make no sense in their placement. Optimal place to lay them on is directly below or above the "cockpit" or the ships aft (or directly at the nose), so you provide the widest possible arc for them to work on. Port and starboard sensors aren't terrible, but their scan arc is limited as well. If something manages to slip close to the sides of the ship, bridge has essentially nothing to see what's happening outside. You might just hide in the shadow of the ship and be completely invisible. That's an awful placement for anything. JUST FUCKING PLACE ALL THE SENSORS AROUND THE HULL.
Bridge placement makes no sense either. You either want to protect your crew, in that case putting bridge as deep inside the ship as it is possible, or you just say "fuck it" and let them die from space trash hitting the front of the ship. It should be the most heaviest armored and protected element, but here it has exposed windows (why the fuck do you put windows on a spaceship that's moving at sublight speeds is beyond me).
Then, where are the maneuvering thursters? How does the ship navigate? It supposedly needs to rotate around its own axis to produce artificial gravity. If that's the case, there's nothing that can put the ship in any sort of movement besides full thrust forwards. Even the most basic satellites we've put on orbit that had more functionality than the Sputnik have tiny maneuvering units (or just RCS) to spin it around. But this thing doesn't.
Radiator fins are tiny, and completely inadequate. Unless there's a sudden change in how vacuum works, this ship would fry its crew fairly quickly. Docking bay is tiny as well and I doubt anything bigger than the Mercury I pod would fit inside, unless the windows on the bridge are 10m tall.
I can't believe this fucking design triggered me so badly. I can't wait for my puzzle pieces.
Plus, the ship is nowhere big enough to provide safe spin required to provide even .1g at the farthest reaching points of the ship.
