When you think about it, Scientifically we really dont know anything.......

You seem to be confusing the difference between Law, Hypothesis, and Theory. Laws don't describe the mechanism that underlies what they are describing. They just describe what will happen given a certain set of circumstances. A Hypothesis is a idea put forward for consideration which matches observation, and is a attempt to explain the underlying mechanism. A Theory is more then a idea however. It has been validated, verified, and applied. In other words a theory isn't just useful it is actively used. Not just to explain things, but to make things.

In Science the vast majority of things we know are Laws. Only a small number of things are dedicated to the conjectures that surround those Laws be it Hypothesis or Theory. Further more when you get right down to it. Most of our Theories are really just a collection of Laws. Even if a flaw is discovered within a theory. Such as finding a situation where it fails, or is obviously lacking a critical detail. Some of the many equations in that theory can still be valid.

For the sake of a example if Einsteins theory of General Relativity were proven to not work at say the very center of Black Holes. It doesn't change the fact that those equations work here in our own Solar System. My cell phone won't suddenly stop working, because that Theory still adequately expresses the temporal difference between me on the Planets surface, and the Satellite in orbit that needs to take my call. The real problem that exists is that math seems to be Universal, and to be honest there isn't any reason to think that isn't the case.

We don't know much of what we know, because of Hypothesis of Theory. Like I said it is a really small part of things. Most of what we know comes from the application of Laws. We know how sound moves through liquids, solids, and gasses. We aren't guessing. We have centuries of experimentation that show us the end result. So when we fire sound waves through the planet, or listen for naturally occurring ones. We just listen, and compare it against the data we collected over all those centuries. Sound moving through Lead doesn't sound anything like sound moving through liquid Iron. We basically don't even need to know why the sound is different. We just need to recognize the sound.

You have to understand something about Scientists. Theoreticians proceeding the Experimentalists is actually a fairly recent phenomena. Theories usually came after the fact. We knew the colors elements produced when heated long before we had a theory to explain why they were different. You are kind of complicating things. We basically know a huge fucking number of things, and you shouldn't get hung up on theorists. Their job is to basically understand them, and try to simplify them into a framework.

Has that answered your question.
