On my Random Idea:Battleship Oververse

[birdmaster01]

Battleship Oververse is a spacecraft roughly in the shape of a cylinder capped on both ends with half spheres.It is 93 billion light years long,from butt to other butt and 43 billion light years in diameter.It floats through the endless void.Inhabitants don't know where it is going or if there even is a destination.They also don't know when this structure they exist inside of was built or when it took flight.They know nothing but that the Oververse was here surrounding them when they were born and it will be still here when they are gone.In this place,everything related to the safety of the peoples falls upon the shoulders of the Lock Paladins,warriors clad in variable sized,usually bipedal suits who wield great power with varying levels of responsibility.A team of these Paladins,during a routine patrol on the surface of the Oververse,get lost and end up in a previously unknown region of the Battleship,they must make their way back to the civilisation by going through this mysterious compartment and maybe figure out what the fuck is this big dumb ship is doing and/or going

This is basically an elevator pitch for my rough space opera idea stemming from sleep deprivation.I would love to hear your opinions on it

Thank you for reading so far

Also mods,please tell me if this thread is improperly tagged/prefixed/whatever,please and thanks for the fish.

So it's the size of the known universe. Why? At that point it the "Battleship Oververse" even moving or is it just the entirety of existence? How would people inside the structure know it's a structure with definite ends as opposed to "just the way the universe is"?

Is there gravity? Does that mean there's a universal "down"? How do you deal with that much mass not collapsing in on itself?

Click to shrink...

Really dependent on a given definition of movement.But there is a void outside it so maybe ?

There is a very well developed transportation system that traverses the entire ship.Very comfortable,nice snacks and such

What is collapse if not the natural state of things in which if everything is collapsing then nothing does
You can also walk on walls,yeah.Except whe you can't but that's most likely a skill issue on the walker's part

If you're in a void, and there's nothing else but void infinitely in all directions, and you take a step to your right, have you actually moved? Or are you in the same place because "the location of yourself" is the only frame of reference you have?

You have a transportation system through the void, except that transportation system would take 900 billion years to get from one side to another. That's functionally impossible to move or communicate through.

My point is that your scale is so big it loses all meaning. That transportation system could be a planet sized "elevator" moving though a void. It could only have people living on 25% of the very outer edge, still support 7 billion people, and have nearly limitless adventures taking place within it. And that's on one tiny elevator out of 10^25 elevators (100 times more elevators than cups of water in the ocean), and not including any of the vast gulfs of space between elevators for people to live.

If you replaced lightyears with meters it would be equally vast from any realistic point of view. It would span the distance from the Sun to Saturn and require the consumption of thousands of solar systems to construct, with potentially dodecillions living on it. And yet it's 10^45 times smaller. You don't need to have a whole universe and need to redefine all known natural laws to make your story semi-plausible.
