Watch the part about the slicing of 2d world looking at the 3d objects. That slice is infinitely large in both dimensions, yet it can't see the 3D objects when they aren't in the same plane.
Now apply the same analogy to our world: our 3D world is just an infinitely large 3D plane in a 4D world. When the objects aren't in our 'plane', we can't see them.

Edit: Didn't notice it was mentioned at the end of the comments, https://news.ycombinator.com/item?id=14472395 https://news.ycombinator.com/item?id=14472395, there's a free version linked from archive.org.
- mabbo 9y agoA favorite novel of mine actually! Hard to believe that it was written in the 1800s, yet still Abbott understood the 4th dimension better than most people today.
- fao_ 9y ago> Hard to believe that it was written in the 1800s Aside from all the misogyny and the style of writing, you mean?
- nanistheonlyist 9y agoVirtue signal a little harder, I dont't think they can hear you in the fourth dimension.
- throwaway135634 9y agoTo be fair I think the misogyny was satirical
- fao_ 9y agoYou obviously know that it wasn't, otherwise you wouldn't have created that throwaway.
- mabbo 9y agoIt was the 1800s. I'm sure that 150 years from now, everything you and I are writing now will be offensive in ways we don't understand today.
