Pulling it "off the wall"

[Katsushiro_Myoshi]

If Emily pulled Bob's world off the wall
or Bob pulled Fred's world off the wall...what would happen?

[thigle]

that surely is tinglingly perplexing question

[thigle]

or what if some mad TetraBob pulled our 3d world out of its own 3-space (which is just a surface for mad TetraBob)? and put it into another slice of his home Tetronia ?

would we even notice ? does each 'what' have its own 'where' as the ancient greeks perceived ? or is there a universal 'where' that holds each and any 'what' in it, as the 'science' would make us believe ? place or space ? ( Yi Tu Fuan would ask).

places arise where spacetime allows.

um...what!?!?!

Okay another question...Does fred's plane have another side? Because he lives in a 1D world which theoretically speaking is a line. And does our 3D "world" have another side? ahah questions

Hi Katsushiro,

These are interesting questions. A 2d plane has 2 sides, and if you flip it around in the 3rd dimension, you can see either one. Perhaps by flipping around our perceived 3D world in the 4th dimension, you can see different "cubes" as well...?

Every (n-1) dimensional subspace splits the (eucledean) n dimensional space into 2 halfs. A line is such an subspace for the plane, a plane for the 3d space, and so on.

Nothing much would happen. Bob or Fred would just feel a lot of shaking, but if Emily or Bob pulled Bob or Fred out of the paper or the four dimensional paper, then something cool would happen.

A plane in this sense doesn't have two sides. It is not a sheet of paper with a thickness and you can write on either the top or bottom surface of what is essentially a very flat rectangular prism. There is only one surface and it is the exact surface in question. You write IN it, not on it.

But a plane may have two sides to be observed from. I think you're right in saying that you cannot write "on" it, but rather "in" it, although you would still be able to view it from two different sides, namely, seeing the reflection when viewing from the opposite side.

It's not going to happen. Its more likely that ye will pull a movie character off the wall. We are intrinsicly laced into the fabric we occupy, and depend on hidden parities to an extent far more than is taken.
