Many of you have probably learned about the image above in school or have heard someone refer to it whenever they try to refute evolution. I'ts the idea that a hypothesis, turns into a theory and then when it gets enough scientific support, it becomes a law. It's all a load of bullshit.
A scientific theory, is a model of reality and the way it works, on the other hand, a scientific law, is descriptive in nature, like gravitation, if two bodies move away from each other the force of gravity between them decreases, a law doesn't tell us why this happens, it just does. Another fine example is how computers work, we know our CPU does all the work, our video card gives us an image on the screen by sending energy through wires and cables, again, we don't know exactly how it happens, it just does. Like when light goes through a prism and it separates into its component colors, it doesn't say why, the law of nature just says it does happen and thats where the theory of light comes along to try and explain whats going on.
Theory and law are two completely different things, one does not become the other. Some people like to say "its only a theory!" suggesting that we can't trust something unless its a law. Theories in reality, are backed up by tons and tons of evidence to support their case, they explain to us how laws work, what really goes on with the light particles, and what gravity does to objects. In fact, its only a theory that right now millions of electrons are going from my keyboard, to the motherboard, and up to the monitor, but, working with that theory will get me quite remarkable results and that indicates that the model, the theory, is very close to how reality works.
So, next time someone tells you that evolution is just a theory be sure to point out to them that the fact that they are not floating around on earth, is also just a theory, and that the fact that they own a working cellphone or computer is also just a theory. A theory is not a hypothesis. Theories are proven facts.
