Den första vetenskapsregeln är att den är baserad på bevis.
Det här betyder:
* Observations and experiments are paramount. Scientists rely on gathering data from the real world through careful observation and experimentation.
* Hypotheses are tested rigorously. Scientists propose explanations for observations (hypotheses) and then design experiments to see if those explanations hold up under scrutiny.
* Conclusions are drawn based on the evidence. Scientists don't simply believe what they want to be true. They draw conclusions based on the evidence they have collected.
While this rule might seem simple, it forms the foundation for the entire scientific process. It ensures that scientific knowledge is grounded in reality and open to revision as new evidence emerges.
