    No. He shows how non euclidean (spherical) space translates to euclidean (flat) space. Description is bullshit.

      There is the cool idea of showing how different dimensions, in our situation where fully visualizing a fourth dimension is fundamentally impossible, could potentially look. Like, yes this is obviously not going to show us a fourth dimension but looking at how a 2D plane can actually be a 3D space if you have the capacity to see it is kinda neat. It’s as close as most people are going to get to visualizing a fourth dimension.

      You’re so focused on how this isn’t a literal representation of something fundamentally impossible to represent that you forgot to exercise your imagination even a little bit.

        There’s nothing to extrapolate here. The description is BS. There’s no such thing as ‘linear plane’ there’s a flat plane and curved plane (with positive and negative curvatures). There’s a thing called linear algebra but it’s not the same. Also planes are 2 dimensional spaces. When you have more dimensions name ‘plane’ doesn’t apply. If you extrapolate BS you’ll get even more BS

          Isn’t the description dumbed down to fit thosoe of us with less than mathematician level brains? :-)

            The description hurts my brain, it doesn’t make any sense to me at all, it just seems to be filled with irrelevant words that sound sciency to someone who doesn’t know what they mean. Like a sci fi script

    Seems to me like it’s demonstrating the projection of a complex three dimensional shape which produces a simple pattern on a two dimensional plane.

    This is like me laying naked on my back with an erection and saying the shadow cast by the sun is a complex timekeeping device.

      I mean typically people refer to planes as hyperplanes once you go past 3D, but I’ve definitely heard them just called “planes” too

      Hyperplanes are just a generalization of planes to higher dimensions. Often you hear the term when working with vectors because, like in 3D, you can define an n-dimensional hyperplane by a surface normal vector and a point. All lines perpendicular (orthogonal) to that normal vector which pass through the point form the plane.

      It’s a useful concept and since we already have a word for that kind of structure in 3D space we just use the same term for it in other dimensions

      Hmmm. I don’t think so but I do think it is incorrectly used here. To me, the 3rd dimensional plane would just be the z axis. If you were talking about the entire 3D shape which they are here, I would just say 3rd dimension.

    Neat. How does this help me violate causality or skip over to a different planet? “Scientists discover we are trapped in an even deeper infinite fractal of hell from which there is no escape.”

      Um, hypothetically speaking, for a ah friend, if I wanted to STOP slipping into the ever deepening abyss of further levels of hell, how might I, oh I mean my friend, accomplish this?
