You are again demonstrating that you don't really understand this topic.
You are equivocating applied science and scientific research by just using the label "science" as if they are the same thing. Scientific research advances knowledge and understanding in a field of study, while applied science takes that knowledge and uses it for applications. For scientific research, testable and repeatable experiments are critical so that others can replicate the research and results. Peer review is an important quality control method for this, because as we see regularly published in garbage pay-to-publish journals, when you don't have peer review you end up with cranks and swindlers presenting their claims as legitimate for gullible people to eat up.
Scientific research is when chemists ran experiments with electricity, metals, and inert gasses and discovered that you could produce different results depending on the materials and currents used. This advanced knowledge in the field of study. Applied science is when people took that knowledge and created practical applications from it such as the commercial light bulb. This didn't advance our knowledge or understanding, it created a practical application for scientific knowledge.
