Yes, of course it can! =D A theory is just a hypothesis that has been tested and supported by numerous experiments. However, if another scientist can argue against a theory, and can sufficiently support his own ideas, the original theory is disproved. So we have to be careful when we say "prove." It is almost impossible to "prove" something in science, but rather ideas are "very well supported." It's also how the science community grows. So hopefully, you can disprove a major scientific theory one day and revolutionize the field of study!
interesting question. I hear lot of people say "but its only a theory, it cant be proved"
However, E=MC^2 and special relativity is supposed to be a theory, yet through experimentation, we can show that these things are correct.
Also there is such a thing as scientific proof.
A scintific law is a statement that describes what scientisis expect to happen. A scintififc theory is a well-tested explantion for a range of observations. This answers the question '' How Does Scientific Law Differ From Scientific Theroy?''
Dependent variable
A law cannot become a theory, as laws are higher in scientific hierarchy than theories. Theories may become laws when the evidence for their factuality proves that the theory meets all established requirements set forth by the theory. If at any point in the scientific method a theory is disproven for the criteria that it sets forth, it can never be considered a Law. The hierarchy is thusly: Hypothesis < Theory < Law.
Yes, they can, if new evidence is discovered to support a change in the theory. Physical theories are not provable in the sense of mathematical theorems. They depend on evidence, and they can be disproved if enough contrary evidence comes up.
A theory is useless if it cannot be tested and verified/disproven. That is the purpose of experiments.

A scientific theory is something that is tried and tested, and not yet disproven. It is close to being scientific 'fact' as you can get. Not all hypotheses will become theories because sometimes they get disproven. That means the hypothesis will need to be changed and tested again.
A scientific law is an indisputable fact: there are no observances dictating it. For example, gravity is a scientific law. A scientific theory is simply a generally accepted explanation for a particular phenomenon or idea that cannot currently be proven or disproven. The structure of the atom and evolution are theories.
No. A theory cannot be disproven. This is a corollary of the fact that a theory cannot be proven either; otherwise it would be a theorem.The correct term for a theory being consistent with evidence and reliable in predictions is validated. The correct term for not being validated, or an overturning of validation, is invalidated.
A theory
in real science, anything with the word theory in-front of it means it hasn't been disproven - for example gravity is a theory.
A postulate is a basic assumption or principle accepted without proof, while a theory is an explanation supported by evidence and experimentation. Postulates serve as starting points for developing theories, which are more comprehensive and detailed explanations of natural phenomena. Theories can be revised or replaced based on new evidence, whereas postulates are typically seen as foundational truths within a particular framework.
Dependent variable
A law cannot become a theory, as laws are higher in scientific hierarchy than theories. Theories may become laws when the evidence for their factuality proves that the theory meets all established requirements set forth by the theory. If at any point in the scientific method a theory is disproven for the criteria that it sets forth, it can never be considered a Law. The hierarchy is thusly: Hypothesis < Theory < Law.
A theory is a proposed idea as an explaination to a problem. A scientific law is a tested and experimentally proven idea that can be considered as truth; until experimentally disproven. Newton's law of gravity was law, proven by experimental observations, right up until Einstein developed special relativity and it was experimentally proven. Thus disproving Newton's "law". String theory is an idea that is quite appealing to physicists, but there is no experimental proof to its validity, so it remains as just a theory.
No. That is the SECOND STEP. In the Scientific Method, the first step is to ask a question or make an observation. The problem / question / observation is the subject of the investigation. Once the question exists, a theory (hypothesis, conjecture) can be made, which can be proven or disproven through experimentation.
