Like I don’t quite get that, they can apparently travel FTL in space, but then they never use it on a planet. Then they travel in ships, but why, if you’re just as fast flying by yourself. Idk if this is explained anywhere and sorry if this has been already answered.
Someone literally asked this 2 days ago. The answer is simple, transportation of resources.Also requires way less effort.they have to hold their breath and if they’re going really far they have to eventually stop on a planet to get some air.But mainly transportation of resources like we see in episode 4, they needed heal the Viltrumites.
The real question is why the ships have engines, and not just a single viltrumite whose job is to push the ship.
