Difference Between Theory and Hypothesis

Many of them belittle evolution because “it is just a theory.” Gravity, on the other hand, must be real because it is a law. The words “theory,” “facts,” “laws” and “hypothesis” have very specific meaning in the scientific world that doesn’t quite match the ones we use in everyday language. Science employs a particular vocabulary to describe how ideas are proposed, tested, validated or disproven. And this is where we see the difference between hypothesis and theory. A hypothesis is a tentative explanation of an observation that can be tested. It acts as a starting point for further explanation. Theory, on the other hand, is an explanation of some aspect of the natural world that’s well-justified by facts, tested hypotheses, and laws. Let us look at more differences between hypothesis and theory given in a tabular column below.

Theory vs Hypothesis

Theory Hypothesis
A theory is a well-vindicated explanation of a natural phenomenon that is validated through observation and experimentation. A hypothesis is an educated guess based on certain data that acts as a foundation for further investigation.
It is based on a wide range of data It is based on limited data
A theory is tested and proven scientifically A hypothesis is not tested and proven scientifically
The results are certain The results are uncertain
It relies on evidence and verification It relies on the possibility

From the above differences, we can infer that a hypothesis might change significantly as the testing occurs. A hypothesis can either be right or wrong. When a hypothesis is tested and proved true, it becomes a theory. At BYJU’S, learn more differences like the difference between asteroid and comet.
