1. ## What you guys think about 4th dimension ?

Whatuuuuup booooyz, how ya all doin' tonigh ? ))

I've been thining about 4th dimension whole class of math today, and I would really like to know what so smart ppl like you guys here think about it.

If you've never heard about it, let me introduce you to a basic 4 dimensional object.
It is called Tesseract, but we can only observe it's 3D shadow / projection.

It's projection (hyper-cube) looks like this (try not to look at it as 1 smaller and 1 bigger sphere, think about it as a perspective projection of a 4D object. AKA object with 4 space directions (up/down | left/right | forward/backward | ???wForward / ???wBackward).
WARNING: "Do not try to imagine 4th dimension at all, you just can't."

There is a great example of how moving with 3D space looks like for a 2D observer.

So with a little bit of introduction, let me ask agin, what you guys think aobut it ? I am like really interested in that.

Before you start with "4th dimension is basically TIME" - first of all I am talking about spacial dimensions, not "timespacial". Second of all, time
is some kind of a "global" dimension in my opinion.

3. Really interesting would be freaky if this was real.

Damn I hope it is. There are some theories, that just like we draw 2D stuff, some 4D creatures are able to "make" us in 3D.

5. Haha confusing it'll probably drive me crazy

6. I hope it exists. We'd be able to do some crazy shit :^)))

7. Now I can't stop thinking about it either...

Haha It's just like trying to imagine a new color ^^

9. 4th dimension is only theoretical in math theory.

In physics it doesn't exist, unless wormholes exist and spacetime can be bent.

If you really think about it like that, everything about spacetime is thory. Even our physics we "know"

11. This is interesting but no point in dwell on this, because I am currently feeling down in the physics department.

Exactly, we all could also just be dreaming, there is no way to proof neither is there one to deny it,
we simply do not know.

Yeah, I guess you are right with that

Mathematical theory and physics theory is completely two different subjects. Infinity exists mathematically, doesn't exist physically.
