All are theories, hypothesis if that's what you would like to call it, based on phisical evidence/artifacts, that can be dated.
........................just sayin'
No, my point was specifically that a theory and a hypothesis are DIFFERENT things - they're not interchangeable
. I'm just pointing out the problem with referring to theories (as the word is used in science) as "just a theory". A theory isn't something that someone just dreamed up - that is a hypothesis. A hypothesis BECOMES a theory when it has sufficient evidence.
To sum it up:
Hypothesis - "This MIGHT be the truth . . ."
Theory - "This PROBABLY IS the the truth . . . "
Law - "This is unquestionably the truth . . ."
The thing is, the scientific community doesn't declare much a law anymore, because when you say it's a law you're not just saying that it's generally true, but that every single detail is true, and we've had scientific laws from long ago get a few details wrong. For example, Newton's Laws. They were declared scientific laws, and for everything that happens on Earth and in nearly all of the Solar System, Newton's "Laws" worked fine. However, we discovered an oddity - according to Newton's Laws, Mercury didn't move right. Turns out, when you get REALLY close to a massive body such as the sun, the equations start producing results that are a little off. In comes Einsteins' THEORY of Relativity. His equations were more complex, produce the correct results in the same situations that Newton's did, but also work even when you get close to a massive body.
So Newton's Laws weren't really 100% correct. From a mathematical standpoint, they work as perfectly viable approximations for anything that happens on Earth, but they were less right then the Theory of Relativity which works in more cases. And so even things that we understand really, really well, we're still hesitant to call a scientific Law. Put it this way - the satellites we're flying to other planets, the GPS systems that will show your coordinates anywhere on the planet, the radio waves that show your TV - they're all built upon a ton of stuff that is "just a theory".
