A scientist develops a new experiment to test atomic theory. His results do not agree with the theory.

What will most likely happen next?
Scientists worldwide will reject atomic theory because of the new results.
The scientist will change his results to agree with the accepted theory.
Other scientists will reject the results because they do not agree with the theory.
The scientist will repeat the experiment to make sure that his results are reliable.

When the results of a new experiment to test atomic theory do not agree with the theory, scientist will repeat the experiment to make sure that his results are reliable.

Explanation:

In the scientific context, each new experiment must be performed with precision and following the steps of the scientific method.

An experiment that does not provide reliable data to demonstrate a theory must be reviewed in detail and performed again to confirm the data obtained in the first attempt.

A theory is a postulate that tries to explain a natural phenomenon, but whose argument can be discussed or does not have the acceptance of a law. When the theory is proven and there are no arguments against it, it can be universally accepted and becomes a law.

The other options are not valid due to:

Scientists worldwide will reject atomic theory because of the new results. A theory cannot be discarded without solid arguments or evidence in order to dismiss it and establish a new one.
The scientist will change his results to agree with the accepted theory. This would be an unethical procedure and unacceptable to the scientific community.
Other scientists will reject the results because they do not agree with the theory. The opinion of other scientists is not enough to dismiss a theory, if it has a valid scientific basis.
