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.
