  • โœ“An early step in the scientific method
  • โœ“Made before experiments are carried out
  • โœ“Can be supported or rejected by evidence
  • โœ“Often phrased as an 'if-then' statement
๐Ÿ“šTheory
  • โœ“A broad explanation supported by extensive evidence
  • โœ“Built from many confirmed hypotheses and experiments
  • โœ“Has survived repeated rigorous testing
  • โœ“Explains a wide range of related observations
  • โœ“Examples include evolution and plate tectonics

Verdict

A hypothesis is a starting guess to be tested; a theory is a powerful explanation backed by mountains of evidence. A theory is not 'just a guess' โ€” it is among the strongest ideas in science.

Frequently asked

Does a hypothesis become a theory?+

Not directly. A theory grows from many tested hypotheses and broad confirmed evidence over time.

Is a scientific theory just a guess?+

No. In science a theory is a well-tested, evidence-backed explanation, far stronger than a guess.

Can a theory be wrong?+

Theories can be refined or replaced if strong new evidence contradicts them, but established ones rarely fail.
