A theory is an idea or ideas that are used to explain something. You can formulate a theory, then work on a theory and develop a theory, which means you create the theory and then add more thoughts and ideas to it.

Scientists have formulated a theory to explain this strange new phenomenon. Now they should find other experts to help develop their theory in order to improve it. Once you have the ideas, you should test the theory to see if it's true. New evidence might support the theory, be in favour of the theory, or challenge the theory, be against the theory.
