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.

For instance, Newton's theory of gravity was considered accurate for hundreds of years, but was later succeeded by Einstein's theories of relativity, which attributes gravitational attraction to the curvature of space-time, and accounts for the non-euclidean reference frame. On a quantum scale, there is yet another theory for gravity, although this does not so much replace relativity as supplement it.

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.
If a scientific theory has been held as true for many years what will happen when a well monitored experiment gives evidence that seems to go against that theory?
If the evidence is accurate, it may disprove the theory.
How are theory laws hypothesis connected?
A scientific theory and a scientific law are similar in that they both propose to describe and predict the behavior of some aspect of nature in terms of a few basic princples. The main difference is that a scientific theory does not yet have enough evidence to verify its validity. A scientific theory becomes a scientific law after enough evidence has been collected, through experimentation, to be reasonably sure that its description of how nature behaves will always be correct. It often takes as long as a hundred years of experiments before a theory is accepted as a law.
How can scientific theory change?
If new evidence or observations falsify a scientific theory, the theory must be changed to adapt to the new data or discarded altogether. The discoverer of the falsification usually publishes his or her results in a peer-reviewed scientific journal, through which the information is presented to the scientific community. Theories are not "official," but they instead rely on consensus and an understanding of the evidence involved and the scientific method. Usually, however, since a hypothesis must be tested rigorously in order to be accepted as theory, the existing theory needs only to be modified or expanded, and not discarded entirely.
Is a well-tested and widely accepted view that best explains certain scientific observations?
A well-supported hypothesis is a theory that appears to have a lot of evidence behind it. This evidence helps to make it seem likely that the hypothesis is true, but it is still just a theory until it has been proven.
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.
When a theory has been established a it cannot change b it must become law c it may be altered or changed or d it becomes accepted scientific principle?
Once a theory is established, it both becomes accepted scientific principle and may be altered or changed at a later point (normally upon discovery of new evidence or through revaluation of existing evidence).
If a scientific theory has been held as true for many years what will happen when a well monitored experiment gives evidence that seems to go against that theory?
If the evidence is accurate, it may disprove the theory.
When can scientific theories be changed or replaced?
Scientific theories can be changed or replaced when there has been significant evidence for the change. The scientific method must be used to create a new hypothesis, which must then be proven.
Is a scientific theory a well tested explanation?
In science a theory is thesis which has been tested time and time again, only once you have sufficient evidence to say that your theory may be true can you then proclaim it a scientific theory and release it to public criticism. A theory will change as our understanding does, it is well tested, but keep in mind it is still a theory.
How are theory laws hypothesis connected?
A scientific theory and a scientific law are similar in that they both propose to describe and predict the behavior of some aspect of nature in terms of a few basic princples.

It often takes as long as a hundred years of experiments before a theory is accepted as a law.
Can scientific theories be replaced?
A scientific theory is the way scientists attempt to explain what they observe through experiments. When a theory has been made it can be changed if experiments alter the understanding of the event that is being observed.
Is the big bang theory a supposition?
No, it is a theory (in the scientific sense). This means that it was proposed, tested rigorously and passing strongly, and no evidence to disprove it has yet been found.
How long has Evolution been debated?
The theory of evolution is no longer debated in the scientific community, because there is no competing theory that satisfactorily explains, or is supported by, the mounting archaeological and genetic evidence. Put simply, evolution is the only scientific theory consistent with this evidence. To distinguish a scientific theory from a common theory, refer to the related question, What is the Scientific Theory?.Elements of the general population have challenged and debated the theory of evolution since Charles Darwin presented his book, On the Origin of the Species, in 1859, and many continue to do so.

How is a scientific law unlike a scientific theory?
scientific law is unlike a scientific theory in a sense that its the next step above a scientific theory.A scientific law is one that has been proven, a scientific theory has not been proven yet.

A well-supported hypothesis is a theory that appears to have a lot of evidence behind it. This evidence helps to make it seem likely that the hypothesis is true, but it is still just a theory until it has been proven.
