Gravity is only a theory. I don't know why they don't tell our students the the Theory of Universial Gravitation was proposed by Newton, but it's only a theory. The other explanation that isn't allow in the schools is that " The Earth Sucks". Join the fight to get the Earth Sucks equal time in the schools. Let the students decide.

Good point, Joker. I suppose that's why scientists talk about the "theory" of evolution.

Right on Batman. But the scientist do more than "talk" about the theory of evolution. That is the important point. They USE it to make predictions and then test the predictions. You can't do that with "The Earth Sucks" of some other stories you may be thinking about.

I think that Batman knows that already, but please name one such prediction.
Robin, I believe you'll find that some scientists throw those terms to their students like hay on a farm, but conclusive empirical evidence for that particular theory leaves something to be desired.
Batman, aren't the predictions that scientists make about that particular theory really nothing more than observations "after the fact?" and not predictions at all?

Wonder Woman, there is no such thing as "conclusive empirical evidence" for a scientific theory. You can only disprove a scientific theory, you can never prove it. When so many test fail to prove a theory wrong, people tend to think of it as a fact, but scientist realize that in the future the theory may need revision to fit new data. But hey, it's spring break. No lectures today.

I'm not sure what you mean here Invisible. For example, many predictions can be made concerning sellar evolution and then a search for that situation can be undertaken. True, if the situation is discovered, then it had occurred many eons ago, but so what? I know, I know, most are thinking of biological evolution. But why, evolution occurs in all braches of science?
