Ironically, facts in science often are more susceptible to change than theories, which is one reason why the word "fact" is not much used in science.

That's a very insightful point, and it hadn't occurred to me look at thinks that way before.

Great post, RA. In fact, I'm going to go back and re-read it.

After going back and looking at my own post, I realize I should be more careful combining prior posts in answering a current one.

FYI, what was in quotes from my reply #4 was taken from an NSF abstract. My original post did include the reference.

The entire rest of the post was my own.

Sigh.
