A scientific theory and a hypothesis differ primarily in that a theory is a well-established framework built upon extensive evidence, whereas a hypothesis is a testable prediction or explanation that is formulated as part of research or experimentation., While the word “theory” is commonly used outside the scientific world to describe a simple hunch, scientists use the term to describe a broadly accepted explanation for an occurrence. The purpose of a theory is to establish a general principle that clearly explains certain phenomena., Hypothesis refers to a supposition, based on few pieces of evidence, as an inception of further research or investigation. A theory is a well-affirmed explanation of natural phenomena, which is frequently validated through experimentation and observation., In science, a theory is a tested, well-substantiated, unifying explanation for a set of verified, proven factors. A theory is always backed by evidence; a hypothesis is only a suggested possible outcome, and is testable and falsifiable., A hypothesis is a specific, testable prediction that is proposed before conducting a research study, while a thesis is a statement or theory put forward to be maintained or proved., A theory, in the scientific context, is a well-substantiated explanation that encompasses a wide range of observations, experiments, and hypotheses. Unlike a hypothesis, a theory is supported by a substantial body of evidence and has withstood extensive testing and scrutiny..
