Why do Don and Ra talk about a lenticular galaxy when our galaxy is spiral?

[4Dsunrise]

Raman says:

I repeat: a spiral galaxy is lenticular if seen sideways. Also neither Don or Ra used 'elliptical'.

And zenmaster just above says:

My understanding is that 4D is about learning 'the thing in itself' - i.e. the 'noumenal', Plato's 'forms', etc.

I agree that our Milky Way is of spiral (face on) and lenticular (edge on) shape and the latest infrared/ultraviolet telescopic views display the more 'noumenal' matter creating an elliptical/lenticular halo as seen edge on.

So the Ra group's 6D 'noumenal-sensing' visual apparatus probably picked up on this.

And we might, in 4D, get to see a few of these 'invisible planets' that Ra talked about, or perhaps the Sphere Being alliance? I could see a less dramatic version of a dozen or so sphere being-type crafts in satellite orbit around the Earth in early 4D.
