In scientific terms, something is only a theory when it has been rigorously tested, confirmed by evidence and peer reviewed many times. I think most people just don't understand what theory, hypothesis and law are in science and confuse them all with colloquial terms.Thick said:The same reason that relativity is still considered a theory, even though there is so much science based around it.Natdaprat said:I still don't know why evolution is still considered a theory.
It's so that if something ever ever comes along to disprove it, scientists don't have to put up with all the ridicule and "neenurneenur" etc.
They try to avoid using absolutes whenever they can.
Evolution is a theory. That doesn't mean it's just some untested or unproven idea. It means it's an idea that has been tested thoroughly, peer review, supported by a large amount of evidence(in this case, perhaps more than any other theory) and generally accepted by the scientific community.
For clarification on the other two terms that people mess up:
A hypothesis is a TESTABLE idea.
A law is a short rule that we assume to be true throughout the universe.
For example, gravity is a theory, but we have the laws of gravity that each explain aspects of how it works.
