You best start visualizing a 4d space Anon. You're in one.

Don't worry, you're not doing anything wrong. There are only 3 dimensions. Time is not a dimension, nor is it physical.

When people talk about visualizing 4D space they mean 4 spatial dimensions.

There are tricks to reasoning in higher dimensions besides the futile attempt to visualize four orthogonal lines.
A dimension is really just an independent parameter, so you can make the parameter whatever you want it to be. You could imagine a fourth dimension as color, where the difference in color of two objects contributes to the overall distance between them, and two objects can overlap in 3d space if they have different colors. Or you could imagine time as a fourth parameter. Or temperature. Get creative.
As a fun exercise, try to imagine what it would look like to rotate 3d shapes by 90 degrees in these spaces

Just break it into 2 spaces. A 3d space and then a line. Every point into your 3d space is also somewhere on your line.

That's because you haven't learned the relevant math. You're supposed to define a topology that reduces the dimensions.

Did you learn the relevant math of 2D <-> 3D transforms in order to build a 3D model in your head to navigate the world through?
No.
Shut up when you have not yourself achieved what OP is trying to do.

OP without my software, the best I can give you for now is this gif and the next. Its the first thing that gave me a glimpse of the 4th.

Stare at this one for awhile and think about it. This is 3D -> 2D -> 3D as you are used to. The trick to 4D vis is to teach your brain to understand there is another layer involved. 4D -> 3D -> 2D -> 3D -> 4D
The first part, from 4D to 2D is already what the animation is, so all you really need to do is learn to interpret 3D information into 4D similar to how you do 2D into 3D.

By staring at this the idea is you examine what your brain is doing in order to turn this 2D image of a deforming trapezoid folding in on itself into a 3D image of a rotating plane. By understanding this better you will be able to look for the same indicators, but framed in 3D with reference to a 4D object.

>> No.11355799

>>11355779
Now that you understand your own current ability to transform a 2D image into 3D you can focus on applying it to 3D->4D.

Pic related is functionally the same thing as previous, its the 3D form of a plane, a cube, undergoing the exact same rotation. Because you are familiar with taking in 3D information at face value, it appears as a cube being deformed in on itself. But the 2D plane did just the same.
All you have to do now is keep glancing between these and thinking about why you can so effortlessly understand 2D as 3D but not 3D as 4D. Soon enough you will see it. A hint that might help is to focus on the idea that far=small near=big. But Im sure you already knew that. What you really need is to just stare at these long enough while thinking about that.

Once you get it, it probably will not last. Our brains evolved to be great at 2D -> 3D because thats how our eyes work. Luckily we also are good enough at general learning that this IS possible, its just difficult. So if you only get a few seconds at a time, be proud of that. You'll know it when you see it. The cube stays a cube. Its just rotation.
