Would that not depend on your inertial frame? Like isn’t the entire concept of being stationary relative to spacetime not an actual thing? I’m not trying to be pedantic, BTW, I literally don’t know the answer to my question.
Yup. Same as the time travel meme that was on the front page recently, this relies on there being a fixed inertial frame which is not a thing in our weird universe.

There might be one, but there is just no way of knowing
No, there cannot be one. It’s been proven, I’m pretty sure.
