when enough evidence contradicts earlier ideas
How do scientific theories develop and change?
no
they can change over time
Theories
To be a fact the theoretical methods used must be replicatable with the same results.Scientific theories can be rejected by new reliable evidence.They Can Change Over TimeAs a theory, it is unproven.For a scientific theory to deserve that name, it can of course not just be idle speculation. There must a strong suggestion that the claim of the theory is true, but a formal and sound proof has not yet been found.
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.

no

constructing plausible theories
When there are more convincing theories occur and proved experimentally, scientist will modify or change the current theories.
Scientific theories can be modified and in some cases completely scrapped based upon new research.

A scientific theory must be based on many repeated correct experiments; also this theory must be related with other accepted theories.
