Is it a wormhole? A black hole? The homonymous black hole's very center, somehow existing outside of one? Is it perhaps a non-sapient, non-carbon-based being who stumbles around aimlessly, with the only purpose of consuming and growing? Or is it just a completely ficticious anomaly, with no real basis on physical laws nor any scientific accuracy, exclusive to the ss13 universe?
Say you want to portray the singulo on a 3D setting (be it a game, a movie or animation), how would you do it? Would it move around freely, or just spin in place? How do you think it'd end up looking?
Would it look like this? (a la Interstellar)
