I'm not sure where you got this notion unless from an extremely old textbook. Here is a fun little history lesson about galaxy morphologies: those "fuzzy" galaxies, spheroids, are called "ETGs" in the field to this day. Spiral-looking galaxies are called "LTGs."I dont have the permissions astrocat has on this site so would astrocat be kind and kindly post this
"ETG" stands for "early-type galaxy" and "LTG" stands for "late-type galaxy." Hubble originally thought, as you proposed here, that the fuzzy spheroid galaxies condensed and began to rotate to form spirals (hence "early" and then "late" types)
