OK. Thanks.
So it goes from hypothesis to theory. But a law can stand on its own? I thought a theory when is tested and retested over and over again and is proven correct, it then becomes a law.
I'll try to remember this distinction between theory and law.
Nope. Laws are just mathematical descriptions of empirical regularities. For example physical objects attract each other with a force that is proportional to the product of their masses and the inverse square of the distance between them. That's the law of gravity.
Theories attempt to explain the mechanisms behind laws. The theory of gravity seeks to find precisely what causes masses to attract each other, i.e. curves in the fabric of spacetime, microscopic particles called gravitons, etc.
