I am writing my first short story in science fiction and am struggling with the issue of gravity.
What would it take to make a planet match Earth's gravity (e.g. Titan (yes, it's a moon but for the sake of argument it's settleable ergo a planet), Mars, or beyond)?
Conversely, what would it take to make a long-term inhabited space station match Earth's gravity?
Gravity is a tricky subject in sci-fi. Do we assume that, without explanation, we can walk on a foreign world the same as we could on Earth (or whatever the central planets are called). Or do we make changes to world, via terraforming or assume like there would be issues with gravity.
Some examples of the above would be Star Wars - Return of the Jedi. Luke seemingly has no problem with gravity when he goes from Tatooine to Endor to Yavin 4, etc. While, on Firefly - they make ready mention of worlds being terraformed to "Earth-that-was" standards, they don't mention how they overcame the issue of gravity. More recently on the show The Expanse, the issue of gravity is front and centre with it having such an effect on some people in some cases it is used in torture for people not from Earth.
My question lays here! What would we need to do in two aspects of space colonization to ensure that we as a people can move freely from one settlement to the other (at least anatomically - if that is the right word).

Please feel free to cite our works in science fiction, hard science, anything to back up your argument except magic. It is important to my story to have something to back this up, so as to not just rely on an attitude of "Meh, it just works."
