❓Hypothesis
- ✓A specific, testable prediction or proposed explanation
- ✓An early step in the scientific method
- ✓Made before experiments are carried out
- ✓Can be supported or rejected by evidence
- ✓Often phrased as an 'if-then' statement
📚Theory
- ✓A broad explanation supported by extensive evidence
- ✓Built from many confirmed hypotheses and experiments
- ✓Has survived repeated rigorous testing
- ✓Explains a wide range of related observations
- ✓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' — 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.
