# What would be the fifth dimensional property of a Tesseract?

Here's another question. If 4+ dimentions are physically manifest, we should be able to go backwards and say that 2 dimentions are physically manifest as well, right? So show me something that is physically and exactly 2 dimentions...
There is nothing physicsally manifest that is 2-dimensional. Dimensional models are only used to explain the properties of the world around us.

Well, that may be your opinion (and you are entitled to it), but string theory heartily disagrees with you.

Well, sting theory postulates the existence of one-dimensional strings, and two-dimensional membranes. These have physical existence (according to the theory).

I'm sorry. I can see the mathematics behind it, but I just can't buy that anything in this universe could physically be only one dimension, let alone two dimensions. I mean we live in a world that depends on 3-D...

BTW, anyone have any feedback on my +3 dimensional "visualization" idea?

Right now you have 3 dimension note that they are all part of the electromagnetic spectrum; are you prepared to accept that each force has its own spectrum?

I don't know!
I'll just be quiet now.
...wait. Maybe I understand this. By that do you mean that we perceive 3-dimensions because of light?

The only reason we see 3-d is that we have two eyes, but if we had one wew would only see 2-d. Better yet, if we had three eyes we would probably see 4-d.

But even if we had one eye, we could deduce through observation that a "2-d" object that we perceive to be as such, has length, width, and depth.

yes, that is where we get string theory.
