hey, would some good space powers be like, the ability to manipulate magnetic fields, or the ability to change something at an atomic/chemical level, or being able to change the weight of something at will? what about gravity manipulation?

All of these are most definitely cool uses for Space that fit the motif really well! Changing the atomic or chemical structure of something, the weight, and gravity, are a few I’ve heard and seen before, but magnetic fields? I hadn’t quite considered that and I love the idea.
