Why can a hypothesis never be “proven” to be true?

• One can never collect enough data to be 100% sure.

• There may always be alternative untested hypotheses that might account for the results.

• Science is limited by our senses.

• Experimental error is involved in every research project.

• Science “evolves”; hypotheses and even theories are always changing.
