Why might scientists change a scientific theory?
If a new theory better fits the data overall or simply because new and significant data disagrees or the method which brought about the original theory is invalid.
Under what conditions can a scientific model or theory change?
A scientific model can change if new evidence is found. If the new evidence that has been found contradicts the model or theory then a scientific model or theory can change.
What is a scientific theory that has been changed due to new evidence?
When new evidence is found, the theory is tested against the new evidence, if the theory and new evidence are compatible then the theory is confirmed, if the new evidence and the theory are not compatible, then this indicates the theory is wrong and the theory must be abandoned or modified. Sometimes a theory will predict that new things (evidence) will be discovered. In such cases when these things are discovered AS PREDICTED, the theory becomes stronger. For instance some of the outer planets were predicted (using orbital and gravitational theory and observation on the orbits of known planets) and they were later discovered close to where they were predicted to be.
What would best describe a theory?
A theory is a guess at what the result of something will be, based on what is already known about it. Theories will often remain unchanged, unless new evidence is found that suggests the theory is incorrect - if this is the case, the theory will be modified in order to better reflect the new evidence
How are scientific theories related to observations and evidence?
Scientist use scientific methods to test the new theory. They also examine all the evidence to see if it supports the new theory. Scientist accept a new theory when many test and pieces of evidence support it.

If new evidence does not support a scientific theory scientists will most likely?
if new evidence doesn't support a scientific theory, scientists will either revise the theory to accommodate the new evidence or discard the theory altogether in favor of a more accurate explanation. This process is crucial for the progress of science as it ensures that theories are continuously tested and refined to reflect our understanding of the natural world.
What is the difference between a scientific theory and a scientific law?
A scientific theory is an explanation supported by evidence and can be modified as new evidence is discovered. A scientific law is a description of a natural phenomenon that is consistent and often expressed mathematically, without explaining why it happens.

What happens when new evidence does not support your theory?
Depends on whether all the theory is being contradicted or only a part of theory faces contradiction. For instance; the theory of evolution by natural selection would take a theory shaking hit if we found fossil rabbits in the Cambrian period, which has not happened. Only part of the theory of evolution by natural selection was contradicted by Mendelian genetics, when Mendel's much better heritability mechanism replaced Darwin's idea about blending inheritance. The theory only got stronger by this ratification.If that new evidence is solid enough, it may require a revision of the theory. If it is just shaky and occurs because of some error in the experiment, it is usually discarded as uncredible.
If careful and accurate scientific measurement disagree wit the measurement presicted bt theory is what?
Exactly how a theory is tested. Or rather, we should say that this is exactly how a hypothesis is tested. If a careful and accurate scientific measurement disagrees with the prediction of a hypothesis, then it never gets far enough to become a theory. But OK. Let's say that everything the hypothesis predicted was conformed by measurement, and the hypothesis was elevated to the rank of Theory. And then, 50 years later, somebody does a new measurement with better equipment, and it doesn't agree with a prediction of the theory. What happens is: The theory has to change. Either we have to find a way to adjust or modify the theory so that it explains the new measurement, or else the theory is discarded. Either way, if the measurement is trustworthy (and can be repeated by others), then the theory can't continue to be accepted in its present form.
When a theory is disproved by further evidence occurs?
When a theory is disproven by further evidence, it means that the predictions or explanations it offers are no longer supported by the new data. This can lead to a revision or rejection of the theory in favor of one that better fits all available evidence. The scientific process encourages updating theories based on new evidence to improve our understanding of the natural world.
What should scientists do if new evidence was found which didnt relate the big bang theory?
Scientists should carefully analyze the new evidence and conduct further research to understand its implications. They should evaluate whether this evidence challenges the current understanding of the Big Bang theory or if it can be integrated into the theory with modifications. Open-mindedness, critical thinking, and rigorous testing are essential in assessing the impact of new evidence on scientific theories.
How are scientific theories related to observations and evidence?
Scientist use scientific methods to test the new theory. They also examine all the evidence to see if it supports the new theory. Scientist accept a new theory when many test and pieces of evidence support it.
If a scientific theory changes does that mean that it was not a good theory to begin with?
No. It means that it was the best theory supported at the time it was formulated. Theories can change if new scientific evidence provides new information.
