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.

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

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

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.

Generally explosions do in fact involve an object suddenly increasing in volume (with corresponding decrease in density)

Said objects typically become partially gaseous, but if the rest of it is porous then it's not unusual at all for that to increase in volume also.

Easy example: popcorn.

Why assume it started off as a sphere? Everything makes sense if it started off as an irregular blob.

It might well have started our as a sphere. But you also need to rotate pieces in the third dimension of you want to pay the sphere back together.

Only if you assume the object was round. I mean it was almost certainly meant to be round, but it could be right ¯\_(ツ)_/¯

If it was round it wouldn't have blown up!

Right? Round isn't what I'd think to call "a funny shape." Maybe some folks do though.

Clearly the artist believes in the axiom of choice

It just means the explosion had so much energy some of it was converted to mass. As you cannot determine what kind of explosion that is, this explanation cannot be disproven in general terms.
