Someone on earth vs someone on the ISS have different gravitational experiences for instance.

The experience is different because the person in the ISS is simply not close enough to Earth to be subjected to Earth's gravity, in any practical amount. But that doesn't mean gravity stopped existing for them.

Ooh, time for science pedantry! The ISS is plenty close enough to Earth to experience almost the same gravity from the planet as on its surface, which is why it has to be orbiting at such speed - falling sideways fast enough and at the right angle so as not to come crashing down!

It sounds like someone still hasn't played KSP! Play it! It's great. You'll learn a lot, and you'll have fun doing it.

Stuff doesn't stay in orbit because there isn't gravity. It stays there because it's moving sideways while it's falling down, so it doesn't hit the thing it's orbiting. Without gravity it'd be able to just sit in space wherever it wants. Rockets mostly don't go up, they go sideways. There wouldn't be a geosyncronus orbit as all orbits would allow you to just sit above any location you want. A geosyncronus orbit is one that the amount it has to move sideways is, in degrees from the center of earth, the same amount the earth rotates.

I wish I could say I've never came across this sort of muppet. But… *sigh*

Yeah...

Wilful control of reality in this case requires truth to be subjective; and conversely, if truth is subjective you can control reality. You're right they aren't the same thing, but they're clearly tied.

Not really....to any of that.

There's no reason gravity control requires a subjective truth.

An unusual level of reality control could exist within an objectively truth based system. It would just have to adhere to the constraints.

Perhaps you mean omnipotence? I'm not sure on that one either, but definitionally it usually implies complete control, im not sure if that's within a fixed system or not.

Reality control and subjectivity can be tied if an example ties them somehow, but it's not a given.

Yep, that's why I went with gravitational experience instead of one having gravity and the other not.

the ISS is simply not close enough to Earth to be subjected to Earth’s gravity, in any practical amount

Imagine being this convinced that one's understanding of gravity is objective truth, while also being this wrong about how gravity works

Wilful control of reality in this case requires truth to be subjective

Hmm, maybe. Others have covered this and it doesn't quite seem perfectly true, but let's let that slide.

and conversely, if truth is subjective you can control reality

No, that definitely doesn't follow. If truth is subjective it doesn't at all mean you can control it. It just means that what is true for you might be different from what is true for me. The reason that's the case isn't a part of that equation.

sort of. they just keep falling and missing

Individual control of truth is a superpower. It definitely violates causality, it also isn't what those people really mean by "truth is subjective"

so it's less of a "truth is relative to ME! ME! ME!"

This, I think, is an argument that exists in your head only. An excellent example of relativity, if I'm being honest.

I don't understand why subjectivity makes people so uncomfortable. Like, people would fight each other over the objectively correct temperature for the AC of their building if you let them—I just, I don't get it.
