Supposed that you have a device that could shift an object’s position on the 4th diamension, or had a 4th dimensional friend that can do it casually who could help you do the same, would you survive the process?
Taking it down a notch, would a 2D being survive being manipulated by 3D movement i.e twisting, shifting, fliping, etc?
I would assume so, since in theory all you’re doing is moving where you are in space. It might be a problem if it’s only done partially over time though
Depends on if existence in this level of 4D is dependent on being at this level. Using your 2D in 3D example (aka Flatland) what if the 2D plane is at sea level pressure, but changing the Z axis there is a different pressure (as we understand, but the shapes would not), to the point where Mr. Square dies if we lift him too far up.
Now imagine a 4D version, where it’s not air pressure, but something more fundamental about physics changes if we’re moved from our current 4D state. The idea being that space as we understand it is 3D, but perhaps exists as part of higher dimensions along with other universes. But they could be completely different, and movement from ours to theirs by just sliding in 4D would change the “space” we’re in, in a bad way.
Or we could just wink out of this 3D space, but be in just a different state and be fine, seeing a weird cross section of what we’re used to.
The 4D force could very much be gravity. Move in one direction and you can fly. Move in the other, get crushed by your own weight.
