Yes ... in theory. Scientific knowledge is always provisional knowledge, that is, not absolutely certain. However, it is very, very rare for a well established scientific theory to be completely overturned. Ordinarily theories are refined by correcting small errors, or by filling in missing parts. Relativity 'superceded' Newtonian Physics, but it did not replace it or find it wrong. Rather it extended it into new realms, and provided a new basis for Gravity (among other things). See the entry for "Theory" in Wikipedia for more. (And always remember, the meaning of "theory" in science is not the same as the meaning in ordinary language, where theory is often used to mean "hypothesis". In science, "Theory" means a well established body of laws and facts.)
Yes. Scientific theories, hypotheses or more generally conjectures must be testable capable of being proved false.
A scientific theory is a theory, no given proof of being a fact, a scientific law is what always happens, essentially a fact. Both is in chemistry and physics. The theory of gravitation happens before it became the Law of gravitation. Scientific theories and laws are similar except laws were proven to be recognize as a fact.
Nearly 100%. Someone who claims something is "just a theory" has already proven they lack an understanding of scientific definitions. This usually means they lack an understanding of the subject which they refered to as just a theory.
BASIC ANSWER>! Scientific law is proven (for the most part) and scientific theory is not proven yet."However scientific law is a law that cannot be broken and scientific theory is an attempt to explain a pattern or a rule repeadetly observed in nature".
A False Positive.
testable
in the scientific method the hypothesis is always assumed correct until proven wrong by the experiment that is being performed
Isn't a theory based on facts and what is proven so far and speculation being what could happen if..
Proof of it being wrong or another improved and better theory.
By being tested against reality multiple times.
