→Facts: it can be understood.
==Facts==
==Facts==
I'm confused here, and as an hostotian, not without good reason. It is a scientific fact there are 8 planets. One year ago it was a scientific fact there were 9 planets. Now, in historical reporting which "fact" do I use? And one reason I got into history is because I don't follow the fads of the moment, which the 8 planet fact theory currently dominates. How do I know science, or what it calls facts, won't change again tomorrow? [[User:RobS|RobS]] 23:10, 3 May 2007 (EDT)

:It's like the word "alive". It has a colloquial meaning, and science has worked with and suffered the consequences. The planets used to be the "wanderers" - the "stars" that moved about the firmament. There used to be 5 known to man (Hg, V, M, J, S) As we got to know our system better, we readily found U & N, and the tiny P. Then we found tens of thousands more and the distinctions blurred. Especially with the identification of a couple of rocks that, were Pluto to be a plant, they would be to. So the a definition was created that pretty much limits the word "planet" to the first eight. By the way, "history" is constantly undergoing revision and deeper understanding, too. [[User:Human|Human]] 00:24, 4 May 2007 (EDT)
