What is a scientific theory can a theory ever be proved to be true?
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not “guesses” but reliable accounts of the real world.
Why would a scientific theory be revised over time?
Why would a scientific theory be revised over time? because new theories can come out that better explain observations and experimental results can replace old theories.
Can a theory be proven?
A scientific theory is not the end result of the scientific method; theories can be proven or rejected, just like hypotheses. Theories can be improved or modified as more information is gathered so that the accuracy of the prediction becomes greater over time.
When can a scientific theory be changed?
Scientists are likely to accept a new or modified theory if it explains everything the old theory did and more. The process of theory change may take time and involve controversy, but eventually the scientific explanation that is more accurate will be accepted.
Is theory of evolution a fact?
Evolution, in this context, is both a fact and a theory. It is an incontrovertible fact that organisms have changed, or evolved, during the history of life on Earth. And biologists have identified and investigated mechanisms that can explain the major patterns of change.”
What constitutes a good theory?
One lesson is that the reason a “good” theory should be testable, be coherent, be economical, be generalizable, and explain known findings is that all of these characteristics serve the primary function of a theory–to be generative of new ideas and new discoveries.
What is the purpose of a good theory?
1. Theory serves the purpose of helping us to bring events which seem randomized and without relationship into meaningful relationship and order. A good theory can help a teacher “make sense” out of the behavior of his students. operationally, in terms of ,the degree of its predictive content.
Does a good theory have to be a true theory?
A theory not only explains known facts; it also allows scientists to make predictions of what they should observe if a theory is true. Scientific theories are testable. New evidence should be compatible with a theory. If it isn’t, the theory is refined or rejected.
