Science finds out about the real world by using all the indicators of truth mentioned above and then engaging in a communal activity. In other words, Science can't be carried out in isolation. This may take the form of an informal remark to a colleague, a seminar to a group of colleagues, or a published article. The last route, publication, is the official route for community dissemination. The act of publication is saying that the scientists think that they have discovered something new and they are announcing this to the science community.
All journals have one or more editors.
Sometimes an article is rejected, even though it is important and correct. If an article contains errors, several things may happen. Sometimes the facts in an article are checked by another group of scientists who then come up with a different story. Sometimes, the authors of the article find that they have made a mistake and they publish a retraction. Sometimes no one pays attention and the article gets forgotten.
