In the physical sciences experiments can be enormously expensive to run and doing them "continuously" is impractical. Groundbreaking work is usually verified independently, but it varies across fields. E.g. physics is usually quite careful about reproducing new physics before accepting it, while in the biological sciences it seems that work isn't always reproduced.
