: : You are not understanding this. This isn't about a : : giant 3d box. It's about giant 4d "box". : It is an 3D box, because time is not an issue. : What I am saying is that by creating the plane YOU create the borders. : Which does not automaticly there is nothing beyond the borders you create.
OK, I see that you are in the wrongest track. So please read next few lines very carefully.
It IS a 4D (4 "spatial" dimensions without time). 2D creatures can't escape from the sphere which is 3D (without time).
3D creatures can't escape from the 4D "sphere"(of course this is not a sphere since is 4 dimensional).
That's what I am saying. When I am talking about 4D I don't include time because, like you said, time is not an issue here.
4th dimension ("spatial" dimension, not time) isn't something we can imagine, so maybe that's why it gets so confusing some times.
That's why I tryed to simplify it a little bit, transfering 3D to 2D. Now if 2D is the maximum number of dimensions (that's true for those imaginary 2D creatures), it is easy for us to understand the dimension they can't understand.
Now, let's get complicated, let's include time. We are living in spacetime (4D space + 1D time = 5D spacetime) which 3 space dimensions are wrapped around 4th and all this includes time, so we have a 5D spacetime. (Hey it's just a theory)
All matter is 3D spatialy extended(Einstein), that's why it can't go pass the 4D enclosure.
If you would draw a lines from one point in space, they would meet at 2 points. One would be at the other "side" of 4D enclosure, and the other would be startpoint.
I hope you are understanding now.
