Yes, if the experiment was repeated 100 times with the same results, the hypothesis could become a theory. A theory is a well-established explanation that has been repeatedly confirmed through observation and experimentation. Therefore, if an experiment is repeated multiple times with the same results, it provides strong evidence to support the hypothesis, which can lead to the development of a theory.
A theory can be created by just one person, but it requires extensive research, experimentation, and peer review to become widely accepted. A theory is a well-established explanation that has been repeatedly confirmed through observation and experimentation, and it must be supported by a large body of evidence. Therefore, a theory cannot be created by just one person without extensive research and experimentation, and without undergoing peer review to ensure its validity.
