Reality of history of physics: why people accept facts finally?

There are more differences between scientific field and unscientific field. Scientific field is the production of reality and others may or may not of the production of reality. When a person works in his own region, the work becomes the subject of research because human generation wants new and real ways for solutions of different problems. No one can neglect the useful and real discovery in physics. But it will be the most important question that the discovery is really discovery or not. If it is really discovery, people accept that either in short time period or in long time period. Because of being the necessity for human generation, facts are accepted finally. So, let us do our work regularly where as people pay attention or not suddenly.
