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

I agree with zenmaster. Although Hubble did invent the galaxy classification early in the last century, before the Hubble Telescope went up (after Don died) we had photos from the Lick Observatory showing galaxies from the edge that looked lens-shaped, ones viewed from near perpendicular that looked as though they would be lens-shaped viewed from the edge and some that looked like glowing footballs. Don's education was in engineering and likely did not include astronomy at all; mine didn't. So when he talked about our "lenticular galaxy," he was asking Ra to distinguish it from their sometime using "galaxy" when they meant our solar system.

Ra apologized for the error, saying they didn't always have the right vocabulary for big systems. If Ra could mistakenly use galaxy for our planetary system, I forgive them for not getting that our stellar galaxy was correctly a "spiral" and not a "lenticular."
