More form the “Xeelee” universe of Stephen Baxter. A GUT ship (Grand Unified Theory) derives power from heating matter to immense temperatures where the fundamental forces unify, releasing huge amounts of energy. A small asteroid is used as propellant. Very early WIP. The dome will be transparent, inside, a small town. For scale it’s about a mile wide and three miles long, hence lots of greebles. Eventually I’ll try and bash this up a bit, I want to depict it after many thousands of years in space.
Big render of the full ship so far :
