The main differences between hypothesis and theory are based on the amount of scientific evidence and the ability to make predictions about a given outcome.
<h3>What is a scientific theory?</h3>
A scientific theory is a well-sustained body of empirical evidence that allows us to make predictions associated with new observations of the real world.
Conversely, a hypothesis is a given explanation that must be tested in order to be confirmed (or rejected) by using the steps of the scientific method.
In conclusion, The main differences between hypothesis and theory are based on the amount of scientific evidence and the ability to make predictions about a given outcome.
