Question	—	Wormhole travel system: how would they connect the systems? Here, star systems are connected with "wormholes". The wormholes facilitate travel at $250c$, regardless of mass. They are made using special ships. Any travel (including military vessels) not through the wormholes is well below light-speed (not more than $0.05c$, ). It takes a road builder ship...

Question	—	A planet with radius 128 km: ocean The planet has a radius of 128 kilometres and the surface gravity is the same as Earth's. My calculations have discovered that the planet would have a density of about 50 times the Earth's: $$gP=gE$$ $$\frac{GMP}{(rP{)}^2}=\frac{GME}{(rE{)}^2}$$ $$\frac{\text{rhoPVP}}{(rP{)}^2}=\frac{\text{rhoEVE}}{(rE{)}^2}$$ $$\frac{\...
