Can't see the other side- if it's a 2 dimensional representation of a 3 dimensional object in can still be accurate because of perspective.

There's a third dimension now?

Not really, but it's a useful assumption for lots of different types of maths.

As long as everything you imagine in 3D space is spherical

Quaternions make a whole lot more sense when you imagine a third spatial axis and use them to rotate a hypothetical 3D object.

This is madness!!!

Yes, time is the third dimension.

Always has been

Yes, and now some bozos are even discussing a 4th dimension. Something to do with chess, I think.

My thoughts precisely, they are just assumimg this is just a 2D circle, when in reality it's more likely to be a 3D sphere. They aren't accounting for the area of a 3D object, we don't even know the thickness of the "slices" that are flying.
