yeah well that's what a klein bottle looks like to simplify things, but really, its more like..
well we can't explain how this occurs because we're only in 3d right now. but its like, the neck of the bottle loops around to connect with the other end, but it passed INSIDE the bottle WITHOUT breaking the surface. it's very messed up, and it similar to the mobius strip but just more complex.
and it's definately in the 4th dimension.
let me try and explain
picture a 1d object (a point) trying to break inside something that's in the 2nd dimension (a circle, for example). it can't right? i mean, it has to break the surface. its like, try to take a penny and slide it inside a piece of yarn that's wound into a circle. you can't, because you'd have to break thru the yarn to get in it.
so what now? the 1d object (point) is moved into the 3RD dimension and allows the 'penny' to lift and then go inside the circle. so there's always a connection between two dimensions and the one in between them.
like in that example, we combined the 1st and 3rd break into the second.
now what scientists predict is that there's some sort of connection between the 2nd and 4th which give us all these heavenly bodies that are spherical and whatnot. i mean, its no coindicence, and there's been some speculation about the klein bottle and this and that.
sorry i'm not better at explaining things, it's difficult to type, but i read alot, this shit is so fascinating
stick that in your pipe and smoke it!
keep it real.
