What would be the fifth dimensional property of a Tesseract?

Click For Summary
The discussion centers on the properties of the fifth dimension in relation to a tesseract and its implications for physics. Participants explore the Kaluza-Klein theory, which attempts to unify gravity and electromagnetism through a compact fifth dimension, but note its limitations in addressing quantum mechanics and other fundamental forces. There is debate about whether time behaves differently in the fourth dimension and how higher dimensions might affect particle tunneling properties. The conversation also touches on the mathematical complexities of higher-dimensional spaces and the nature of forces as curvatures in spacetime. Overall, the thread reflects a deep inquiry into the intersection of geometry, physics, and the nature of reality.

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.
