And, first post.
Um.. I have to add something to the topic... ummmmm.....
Well, couldn't you call anything a "group" or a cluster? Like, for example, you could call one half of the universe the 2nd largest cluster of
planets and black holes and space matter and quasars and stars, etc...... Wouldn't that be an individual structure, if you stated them as bundled all
together like that?
me not know.
