When there wrong about there theory. Like for example , if a scientist creates a new theory, but research proved it incorrect.
theory is when a researcher, scientist, physician, nurse etc has an idea. testing is when they go to prove it either on humans or animals.
Scientist are always testing their models to get new information or results, but other times learning evidence makes scientist have to change their models so scientist can change their models in theory.
I guess it's because science today doesn't know everything we will ever know and there are still discoveries to be made which might change what we believe to be fact.
Incorrect. In science, a theory is a well-substantiated explanation of some aspect of the natural world that is based on a body of evidence and has withstood testing and scrutiny. It is more than a best guess; it is a framework that explains a wide range of phenomena and is supported by multiple lines of evidence.
A psychologist would use the scientific method to test a theory, just as any other scientist would.
They explain all of the observations about a topic that scientist s have at a certain time.
Hypotheses are based on theories. If a hypothesis seems incorrect then a scientist knows that she has been mistaken about her understanding of the theory, and that's why she formed the wrong hypothesis to test. Or it might be that she has learned that there are new conditions under which the theory does not hold, and that the theory must be refined. Both of these are useful to scientists.
A hypothesis is a temporary explanation for some observation. It is then tested and, if is found to be incorrect, a new one has to be formed. If found to be correct, it becomes a theory. If that theory is later found to have a counter-example it is modified (hypothesis -> theory - same process) or a completely new hypothesis proposed and tested. The hypothesis alwasy comes before the theory. it is a practical explanation that the scientist develops that accounts for a theory.
I believe that theory is called the Heisenberg Uncertainty Principle.
