Often times, the religiously drowned population, as well as just non-science people with honest intentions, like to use the word "theory" against a scientific concept. Let's face it, outside of the scientific community people know not a thing about science. To be widely considered a theory in science is a great honor. One can certainly call their concept a theory. But to become appropriate labeled a theory, a hypothesis must go through rigorous testing, many times by many different independant organizations. There is no particular rule as to the label of a concept. As you can see in my new post called "the world as I have come to see it" physics is the hardest science. Thus things in physics often recieve the term LAW. It's a fundamental principle, VERY FUNDAMENTAL. And something that shapes the entire existance of that area of science. Such as netwon's laws. A Theory and Law require the same rigorous testing. THEORY is just a term used in lesser sciences that are more complex. Because they're more complex, humans would probably make more mistakesss in their studies. That's the main reason LAWS are reserve for physics. You can also see some LAWS in chemistry, but rarely in biology. So, don't ever say "it's just a theory". To say that is to saw "It's just considered absolutely true and proven by hundreds of independant tests". It makes you, to the scientific community, certainly look like a mule. Remember, this is for widely accepted theories, in its given community. If you're questioning something in science you MUST: 1. Be in the scientific community. Don't you dare be religious either. 2. Have extraordinarily documented evidence, or a good plan to carry out the scientific method. As I stated before, this regards evolutionary theory. Evolution is a group of evolutionary agents. All accepted agents have been proven to exist in every niche and every ecosystem on our planet. Every single one. Don't you dare refute it unless you've done some serious investigation and experimentation. You just look downright stupid.
