Using the example i listed, i was thinking either a machine functioning sort of like elevators (maybe revolving door better?), or a 4D being touching you to shift where you are like how we rotate a piece of paper.

Something more subtle like, i doubt we survive a equivalent of being strapped to a rocket

Huh, that’s surprising close to what i was thing of!

*Sidenote - of course it would be the US to be the one to have invented it
